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
