Standard NXP headers
firmware/config/boards/kinetis/OS/os/common/ext/CMSIS/KINETIS
To address Kinetis #e10536 errata we need to sleep 100 cycles to make watchdog happy.
This is taken care by
firmware/config/boards/kinetis/OS/os/common/startup/ARMCMx/compilers/GCC/startup_ke1xf.S
which is executed prior to the default firmware/ChibiOS/os/common/startup/ARMCMx/compilers/GCC/crt0_v7m.S
Linker script for 512K ROM
firmware/config/boards/kinetis/OS/os/common/startup/ARMCMx/compilers/GCC/ld/MKE1xF512.ld
flash1a & flash1b is some hardware configuration magic
_bca is flash1a via .bcaconfig
_cfm is flash1b via .cfmconfig
firmware/config/boards/kinetis/OS/os/hal/ports/KINETIS/KE1xF/fsl contains Kinetis SDK files with modifications:
1) include hal.h in the beginning
2) firmware/config/boards/kinetis/OS/os/hal/ports/KINETIS/KE1xF/fsl/fsl_lpuart.c has UART patch (see AndreiKA tag)

Here is the magic here
1) AndreiKA has downloaded libtinyc from somewhere
2) AndreiKA has compiled libtinyc locally
3) AndreiKA has taken some of the .o object files and pasted those here
4) AndreiKA has added his custom libc_stub.c
libtinyc.a is the gcc library produced from all the above mentioned object files
todo: open question where is the official home of libtinyc
This is about wasting as little RAM as possible. Even complete libtinyc wastes some RAM.

rusEfi runs on MKE16F512 (alpha version as of July 2019)
rusEfi Kinetis implementation consists of three files/folders:
firmware/config/boards/kinetis
firmware/hw_layer/ports/kinetis
firmware/hw_layer/trigger_input_comp.cpp
Since MKE16F512 is the first not stm32 rusEfi implementation, AndreiKA has a lot of fun!
Kinetis overrides are in
firmware/config/boards/kinetis/rusefi_hw_enums.h overrides pins
firmware/config/boards/kinetis/config/rusefi_config_kinetis.txt
todo:
have rusefi_stm32_hw_enums.h
have rusefi_kinetis_hw_enums.h
move more generated files to 'generated' folder(s)
maybe generated_stm32?
todo:
move firmware/config/boards/kinetis/config/!gen_enum_to_string.bat somewhere else? merge with stm32?
At the moment we use internal RC generator. Open question if it's good enough.

# How to program
Used to be NXP_Kinetis_Bootloader_2_0_0 KinetisFlashTool and it's not clear how to download it now :(
We happen to have https://github.com/rusefi/rusefi_external_utils/raw/master/Kinetis/FSL_Kinetis_Bootloader_2.0.0_repack.zip
