these are causing some boards to crash on startup. Tested with a
QiotekZealotH743 which doesn't get out of setup_usb_strings()
once we have debugged this we can re-add the functionality
use regular ChibiOS RAM areas for RAM functions
exclude board.o from RAM functions and add some comments
use separate linker script for H750
use correct RAM area for process stack on H750/H743
update EXCLUDE items to put __early_init in flash on H730 and H750
optimize H730 ramfunc usage
Added support for stm32l4+ processor
- Added scripts for hwdef generation
- Tested in custom hardware prototype (stm32l4r5vit6)
- Tested all peripherals and auto pilot modes.
this fixes an issue where a variable in SRAM1 gets set to a bad value
when we reset AHB1 with the top bit (a reserved bit)
the bug was only reproducible with this particular commit:
https://github.com/tridge/ardupilot/commits/cubeorangplus-crash-boot-bisect
but likely is just luck that it triggered on that commit. In this
instance it triggered as AP_OSD::singleton was reset to non-nullptr,
causing a panic() in AP_OSD::AP_OSD()
compiler was gcc 10.2-2020-q4
hwdef for DevEBoxH7v2
pin definitions for STM32H750
add QSPI to DevEBox bootloader

rename EXTERNAL_PROG_FLASH_MB to EXT_FLASH_SIZE_MB
Add support for EXT_FLASH_RESERVE_START_KB and EXT_FLASH_RESERVE_END_KB
Disable HAL_ENABLE_SAVE_PERSISTENT_PARAMS when there is no bootloader flash available
relax storage health status with SD card backend
don't check SD card health unless USE_POSIX
binary sections rearranged on external ram
manage RAMFUNC through ldscript and optimize function placement in external flash
inline timer functions
optimize placement of ChibiOS and functions in ITCM and AXI RAM
fix chibios features on bootloader build with external flash
change H750 memory layout
increase line storage for SD card based parameters
comment external flash linker script
move vtables into DTCM
update ram map for H757
enable crashdump support with external flash
correct bootloader pins and generator on SPRacingH7/DevEBoxH7v2
setup external flash reserve regions
allow different RAM_MAP for external flash on H750 and H757
