Add ChibiOS support for QMK (#465)

* Modularity and gcc warnings fixes.

* Add ChibiOS support (USB stack + support files).

* Make usb_main more USB_DRIVER #define independent.

* Move chibios to tool.

* Implement jump-to-bootloader.

* Small updates.

* Fix bootloader-jump compiling.

* Move AVR specific sleep_led.c into avr.

* Add basic sleep_led for chibios.

* Update chibios README.

* NKRO fixes.

* Rename some Makefile defines.

* Move STM32 bootloader address config to separate .h file.

* Add ARM Teensies bootloader code.

* Fix chibios/usb_main GET_REPORT handing.

* Add missing #include to keymap.c.

* Make bootmagic.c code portable (_delay_ms -> wait_ms).

* Move declaration of keymap_config.

Should really not declare variables in .h files - since it's included
in different .c files, a proper linker then complains that the same
variable is declared more than once (once for each .c file that the
offending .h is included in).

* Add eeprom support for chibios/kinetis.

* Rename chibios example keyboard.

* Move chibios/cortex selection to local Makefiles.

* Chibios: use WFI in idle. WIP suspend stuff.

* ChibiOS/kinetis: sending remote wakeup.

* ChibiOS/STM32: send remote wakeup.

* Fix report size of boot protocol.

* Fix drop key stroke

Keyboard report should be checked if its transfer finishs successfully.
Otherwise key stroke can be missing when other key event occurs
before the last report transfer is done.

Boot protocol 10ms interval probably causes this problem in case
it receives key events in a row within the period. NKRO protocol
suffers less or nothing due to its interval 1ms.

* Chibios/usb_main: rename a variable for clarity.

* Add correct chibios/bootloader_jump for infinity KB.

* ChibiOS: make reset request more CMSISy.

* Chibios: Add breathing sleep LED on Kinetis MCUs.

* ChibiOS: Update infinity bootloader code to match updated ChibiOS.

* ChibiOS: prettify/document sleep_led code.

* Chibios: Remove the wait in the main loop.

* Add maple mini code.

* Do timeout when writing to CONSOLE EP queue.

Fixes TMK bug #266.

* Chibios: add 'core/protocol' to the makefiles' search path.

* Chibios: Update to new USB API.

* Chibios: add more guards for transmitting (fix a deadlock bug).

* Add update for chibios in README

* Chibios: Fix a HardFault bug (wait after start).

* Chibios: cleanup usb_main code.

* Chibios: Revert common.mk change (fix AVR linking problem).

* core: Fix chibios user compile options

Compile options can be defined in project Makefile such as UDEFS, UADEFS, UINCDIR, ULIBDIR and ULIBS.

* Sysv format for ChibiOS arm-none-eabi-size

Some new patches to ChibiOS puts heap as it's own section. So the
berkeley format is now useless, as the heap will be included in the
BSS report. The sysv format displays the bss size correctly.

* Fix hard-coded path of CHIBIOS

* Add support for new version of ChibiOS and Contrib

The Kinetis support has moved to a separate Contrib repository in
the newest version of Chibios. There has also been some structure
changes. So this adds support for those, while maintaining back-
wards compability.

* Update ChibiOS instructions

* Chibios: implement sleep LED for STM32.

* Chibios: Update the main chibios README.

* Chibios: fix STM32_BOOTLOADER_ADDRESS name.

* Chibios: make the default bootloader_jump redefinable (weak).

* Chibios: disable LTO (link-time optimisation).

With LTO enabled, sometimes things fail for mysterious reasons
(e.g. bootloader jump on WF with LEDs enabled), just because the
linker optimisation is too aggressive.

* Chibios: add default location for chibios-contrib.

* ChibiOS: update mk to match chibios/master.

* ChibiOS: update instructions.md.

* Add chibi_onekey example.

* Add comments to chibi_onekey Makefile.

* Rename some Makefile defines.

* Move STM32 bootloader address config to separate .h file.

* Rename chibios example keyboard.

* Move chibios/cortex selection to local Makefiles.

* Add Teensy LC onekey example.

* Chibios: use WFI in idle. WIP suspend stuff.

* Update chibi/teensy instructions.

* Update chibios/Teensy instructions.

* Add infinity_chibios

* Add keymap_hasu.c

* Infinity_chibios: select correct bootloader_jump.

* Infinity_chibios: improve comments.

* Add generic STM32F103C8T6 example.

* Add maple mini code.

* STM32F103x fixes.

* Add maple mini pinout pic.

* Chibios: updates for 3.0.4 git.

* Chibios: rename example stm32_onekey -> stm32_f072_onekey.

* Chibios: add makefiles for Teensy 3.x examples.

* Chibios: update Teensy 3.x instructions.

* Chibios: Tsy LC is cortex-m0plus.

* Chibios: add more guards for transmitting (fix a deadlock bug).

* Change README for chibios

* Chibios: update examples to current chibios git.

Match the changes in mainline chibios:
 - update chconf.h
 - update supplied ld scripts structure
 - update Teensy instructions (switch to official
    chibios and introduce contrib)

* Add ChibiOS and ChibiOS-Contrib submodules

Also fix the makefile path for them.

* Moves chibios keyboards to keyboards folder

* First version of ChibiOS compilation

Only the stm32_f072_onkey keyboard is ported at the moment. It
compiles, but still doesn't link.

* More chibios fixes

It now compiles without warnings and links

* Move the teensy_lc_onekey to the keyboards folder

* Clean up the make file rule structure

* Remove keymap_fn_to_action

* Update more ChibiOS keyboards to QMK

Most of them does not compile at the moment though.

* Use older version of Chibios libraries

The newest ones have problems with compilation

* Remove USB_UNCONFIGURED event

It isn't present in the older version of ChibiOS

* Fix the infinity_chibios compilation

* Fix potentially uninitialized variable

* Add missing include

* Fix the ChibiOS makefile

* Fix some Chibios keyboard compilation

* Revert the rules.mk file back to master version

* Combine the chibios and AVR makefiles

With just the required overrides in the respective platform
specific one.

* Slight makefile restrucuring

Platform specific compiler options

* Move avr specific targets out of the main rules

* Fix ChibiOS objcopy

The ChibiOS objcopy needs different parameters, so the parameters
are moved to the corresponding platform rule file

* Fix the objcopy for real this time

The comands were moved around, so chibios used avr and the ohter
way around.

Also change the objsize output format

* Fix the thumb flags

* Fix the infinity hasu keymap

* Per platform cpp flags

* Add gcc-arm-none-eabi package to travis

* Add arm-none-eabi-newlib to travis

* Fix the name of the libnewlib-arm-none-eabi lib

* Fix the ChibiOS paths

So that they are properly relative, and builds don't generate
extra folders

* Fix the board path of stm32_f103_onekey

* Only consider folders with Makefiles as subproject

+# Teensy LC, 3.0, 3.1, 3.2 support
+
+These ARM Teensies are now supported through [ChibiOS](http://chibios.org).
+
+You'll need to install an ARM toolchain, for instance from [gcc ARM embedded](https://launchpad.net/gcc-arm-embedded) website, or using your favourite package manager. After installing, you should be able to run `arm-none-eabi-gcc -v` in the command prompt and get sensible output. This toolchain is used instead of `avr-gcc`, which is only for AVR chips. Naturally you'll also need the usual development tools (e.g. `make`), just as in the AVR setting.
+
+Next, you'll need ChibiOS. For Teensies, you'll need code from two repositories: [chibios-main](https://github.com/ChibiOS/ChibiOS) and [chibios-contrib](https://github.com/ChibiOS/ChibiOS). If you're not using git, you can just download a [zip of chibios from here](https://github.com/ChibiOS/ChibiOS/archive/a7df9a891067621e8e1a5c2a2c0ceada82403afe.zip), unpack the zip, and rename/move the unpacked directory (named `ChibiOS-<long_hash_here>`) to `tmk_core/tool/chibios/chibios` (so that the file `tmk_core/tool/chibios/chibios/license.txt` exists). Now the same procedure with a [zip of chibios-contrib from here](https://github.com/ChibiOS/ChibiOS-Contrib/archive/e1311c4db6cd366cf760673f769e925741ac0ad3.zip): unpack and move `ChibiOS-Contrib-<long_hash_here>` to `tmk_core/tool/chibios/chibios-contrib`.
+
+(If you're using git, you can just clone the two repos: [chibios](https://github.com/ChibiOS/ChibiOS) and [chibios-contrib](https://github.com/ChibiOS/ChibiOS-Contrib). However - be warned that things may be somewhat out-of-sync (updates at different rates), so you may need to hunt a bit for the right commits.)
+
+(Why do we need chibios-contrib? Well, the main repo focuses on STM32 chips, and Freescale/NXP Kinetis chips are supported via the Contrib repository.)
+
+This should be it. Running `make` in `keyboard/teensy_lc_onekey` should create a working firmware in `build/`, called `ch.hex`.
+
+For more notes about the ChibiOS backend in TMK, see `tmk_core/protocol/chibios/README.md`.
+
+## About this onekey example
+
+It's set up for Teensy LC. To use 3.x, you'll need to edit the `Makefile` (and comment out one line in `mcuconf.h`). A sample makefile for Teensy 3.0 is provided as `Makefile.3.0`, can be used without renaming with `make -f Makefile.3.0`. Similarly for Teensy 3.2, there's `Makefile.3.2`.
+
+## Credits
+
+TMK itself is written by hasu, original sources [here](https://github.com/tmk/tmk_keyboard).
+
+The USB support for Kinetis MCUs is due to RedoX. His ChibiOS fork is also [on github](https://github.com/RedoXyde/ChibiOS); but it doesn't include Teensy LC definitions.
+
+## Features that are not implemented yet
+
+Currently only the more fancy suspend features are not there (power saving during suspend). The rest should work fine (reports either way are welcome).
+
+# Matrix programming notes
+
+The notes below explain what commands can be used to examine and set the status of Teensy pins.
+
+## ChibiOS pin manipulation basics
+
+### Pins
+
+Each pin sits on a "port", each of which comprises at most 32 individual pins.
+So for instance "PTC5" from Kinetis manual/datasheet refers to port C (or GPIOA), pin 5. Most functions dealing with pins take 2 parameters which specify the pin -- the first being the port, the second being the pin number.
+
+Within ChibiOS, there are definitions which simplify this a bit for the Teensies. `TEENSY_PINn_IOPORT` represents the port of the MCU's pin connected Teensy's PIN `n`, and `TEENSY_PINn` represents its MCU's pin number.
+
+### Mode
+
+A MCU pin can be in several modes. The basic command to set a pin mode is
+
+        palSetPadMode(TEENSY_PINn_IOPORT, TEENSY_PINn, PAL_MODE_INPUT_PULLUP);
+
+The last parameter is the mode. For keyboards, the usual ones that are used are `PAL_MODE_INPUT_PULLUP` (input with a pullup), `PAL_MODE_INPUT_PULLDOWN` (input with a pulldown), `PAL_MODE_INPUT` (input floating, a.k.a. Hi-Z), `PAL_MODE_OUTPUT_PUSHPULL` (output in the Arduino sense -- can be then set HIGH or LOW).
+
+### Setting
+
+Pins are set HIGH (after they've been put into `OUTPUT_PUSHPULL` mode) by
+
+        palSetPad(TEENSY_PINn_IOPORT, TEENSY_PINn);
+
+or set LOW by
+
+        palClearPad(TEENSY_PINn_IOPORT, TEENSY_PINn);
+
+Toggling can be done with
+
+        palTogglePad(TEENSY_PINn_IOPORT, TEENSY_PINn);
+
+Alternatively, you can use
+
+        palWritePad(TEENSY_PINn_IOPORT, TEENSY_PINn, bit);
+
+where `bit` is either `PAL_LOW` or `PAL_HIGH` (i.e. `0` or `1`).
+
+### Reading
+
+Reading pin status is done with
+
+        palReadPad(TEENSY_PINn_IOPORT, TEENSY_PINn);
+
+The function returns either `PAL_HIGH` (actually `1`) or `PAL_LOW` (actually `0`).
+
+### Further docs
+
+All the commands that are available for pin manipulation through ChibiOS HAL are documented in [ChibiOS PAL driver docs](http://chibios.sourceforge.net/docs3/hal/group___p_a_l.html).

 QMK is developed and maintained by Jack Humbert of OLKB with contributions from the community, and of course, [Hasu](https://github.com/tmk). This repo used to be a fork of [TMK](https://github.com/tmk/tmk_keyboard), and we are incredibly grateful for his founding contributions to the firmware. We've had to break the fork due to purely technical reasons - it simply became too different over time, and we've had to start refactoring some of the basic bits and pieces. We are huge fans of TMK and Hasu :)

+
+This library is realy just two files: 'printf.h' and 'printf.c'.
+
+They provide a simple and small (+200 loc) printf functionality to 
+be used in embedded systems.
+
+I've found them so usefull in debugging that I do not bother with a 
+debugger at all.
+
+They are distributed in source form, so to use them, just compile them 
+into your project. 
+
+Two printf variants are provided: printf and sprintf. 
+
+The formats supported by this implementation are: 'd' 'u' 'c' 's' 'x' 'X'.
+
+Zero padding and field width are also supported.
+
+If the library is compiled with 'PRINTF_SUPPORT_LONG' defined then the 
+long specifier is also
+supported. Note that this will pull in some long math routines (pun intended!)
+and thus make your executable noticably longer.
+
+The memory foot print of course depends on the target cpu, compiler and 
+compiler options, but a rough guestimate (based on a H8S target) is about 
+1.4 kB for code and some twenty 'int's and 'char's, say 60 bytes of stack space. 
+Not too bad. Your milage may vary. By hacking the source code you can 
+get rid of some hunred bytes, I'm sure, but personally I feel the balance of 
+functionality and flexibility versus  code size is close to optimal for
+many embedded systems.
+
+To use the printf you need to supply your own character output function, 
+something like :
+
+    void putc ( void* p, char c)
+        {
+        while (!SERIAL_PORT_EMPTY) ;
+        SERIAL_PORT_TX_REGISTER = c;
+        }
+
+Before you can call printf you need to initialize it to use your 
+character output function with something like:
+
+    init_printf(NULL,putc);
+
+Notice the 'NULL' in 'init_printf' and the parameter 'void* p' in 'putc', 
+the NULL (or any pointer) you pass into the 'init_printf' will eventually be 
+passed to your 'putc' routine. This allows you to pass some storage space (or 
+anything realy) to the character output function, if necessary. 
+This is not often needed but it was implemented like that because it made 
+implementing the sprintf function so neat (look at the source code).
+
+The code is re-entrant, except for the 'init_printf' function, so it 
+is safe to call it from interupts too, although this may result in mixed output. 
+If you rely on re-entrancy, take care that your 'putc' function is re-entrant!
+
+The printf and sprintf functions are actually macros that translate to 
+'tfp_printf' and 'tfp_sprintf'. This makes it possible
+to use them along with 'stdio.h' printf's in a single source file. 
+You just need to undef the names before you include the 'stdio.h'.
+Note that these are not function like macros, so if you have variables
+or struct members with these names, things will explode in your face.
+Without variadic macros this is the best we can do to wrap these
+fucnction. If it is a problem just give up the macros and use the
+functions directly or rename them.
+
+For further details see source code.

+## TMK running on top of ChibiOS
+
+This code can be used to run TMK keyboard logic on top of [ChibiOS], meaning that you can run TMK on whatever [ChibiOS] supports. The notable examples are ARM-based Teensies (3.x and LC) and on the boards with STM32 MCUs.
+
+### Usage
+
+- To use, [get a zip of chibios](https://github.com/ChibiOS/ChibiOS/archive/a7df9a891067621e8e1a5c2a2c0ceada82403afe.zip) and unpack/rename it to `tmk_core/tool/chibios/chibios`; or you can just clone [the repo](https://github.com/ChibiOS/ChibiOS) there. For Freescale/NXP Kinetis support (meaning ARM Teensies and the Infinity keyboard), you'll also need [a zip of chibios-contrib](https://github.com/ChibiOS/ChibiOS-Contrib/archive/e1311c4db6cd366cf760673f769e925741ac0ad3.zip), unpacked/renamed to `tmk_core/tool/chibios/chibios-contrib`. Likewise, for git-savvy people, just clone [the repo](https://github.com/ChibiOS/ChibiOS-Contrib) there.
+- Note: the abovementioned directories are the defaults. You can have the two chibios repositories wherever you want, just define their location in `CHIBIOS` and `CHIBIOS_CONTRIB` variables in your `Makefile`.
+- You will also need to install an ARM toolchain, for instance from [here](https://launchpad.net/gcc-arm-embedded). On linux, this is usually also present as a package for your distribution (as `gcc-arm` or something similar). On OS X, you can use [homebrew](http://brew.sh/) with an appropriate tap.
+
+### Notes
+
+- Some comments about ChibiOS syntax and the most commonly used GPIO functions are, as well as an example for ARM Teensies, is [here](https://github.com/tmk/tmk_keyboard/blob/master/keyboard/teensy_lc_onekey/instructions.md).
+- For gcc options, inspect `tmk_core/tool/chibios/chibios.mk`. For instance, I enabled `-Wno-missing-field-initializers`, because TMK common bits generated a lot of warnings on that.
+- For debugging, it is sometimes useful disable gcc optimisations, you can do that by adding `-O0` to `OPT_DEFS` in your `Makefile`.
+- USB string descriptors are messy. I did not find a way to cleanly generate the right structures from actual strings, so the definitions in individual keyboards' `config.h` are ugly as heck.
+- It is easy to add some code for testing (e.g. blink LED, do stuff on button press, etc...) - just create another thread in `main.c`, it will run independently of the keyboard business.
+- Jumping to (the built-in) bootloaders on STM32 works, but it is not entirely pleasant, since it is very much MCU dependent. So, one needs to dig out the right address to jump to, and either pass it to the compiler in the `Makefile`, or better, define it in `<your_kb>/bootloader_defs.h`. An additional startup code is also needed; the best way to deal with this is to define custom board files. (Example forthcoming.) In any case, there are no problems for Teensies.
+
+
+### Immediate todo
+
+- power saving for suspend
+
+### Not tested, but possibly working
+
+- backlight
+
+### Missing / not working (TMK vs ChibiOS bits)
+
+- eeprom / bootmagic for STM32 (will be chip dependent; eeprom needs to be emulated in flash, which means less writes; wear-levelling?) There is a semi-official ST "driver" for eeprom, with wear-levelling, but I think it consumes a lot of RAM (like 2 pages, i.e. 1kB or so).
+
+### Tried with
+
+- Infinity, WhiteFox keyboards
+- all ARM-based Teensies
+- some STM32-based boards (e.g. ST-F072RB-DISCOVERY board, STM32F042 breakout board, Maple Mini (STM32F103-based))
+
+## ChibiOS-supported MCUs
+
+- Pretty much all STM32 chips.
+- K20x and KL2x Freescale/NXP chips (i.e. Teensy 3.x/LC, mchck, FRDM-KL2{5,6}Z, FRDM-K20D50M), via the [ChibiOS-Contrib](https://github.com/ChibiOS/ChibiOS-Contrib) repository.
+- There is also support for AVR8, but the USB stack is not implemented for them yet (some news on that front recently though), and also the kernel itself takes about 1k of RAM. I think people managed to get ChibiOS running on atmega32[8p/u4] though.
+- There is also support for Nordic NRF51822 (the chip in Adafruit's Bluefruit bluetooth-low-energy boards), but be aware that that chip does *not* have USB, and the BLE softdevice (i.e. Bluetooth) is not supported directly at the moment.
+
+## STM32-based keyboard design considerations
+
+- STM32F0x2 chips can do crystal-less USB, but they still need a 3.3V voltage regulator.
+- The BOOT0 pin should be tied to GND.
+- For a hardware way of accessing the in-built DFU bootloader, in addition to the reset button, put another button between the BOOT0 pin and 3V3.
+- There is a working example of a STM32F042-based keyboard: [firmware here](https://github.com/flabbergast/flabber_kbs/tree/master/kb45p) and [hardware (kicad) here](https://github.com/flabbergast/kicad/tree/master/kb45p). You can check this example firmware for custom board files, and a more complicated matrix than just one key.
