Summary

  • Remap FMC banks on Arduino boards to support an M4 SDRAM-based firmware.
  • Update Arduino library submodule.

Testing

  • Test the usually Open-AMP examples, additionally Arduino M4 sketch/firmware can now run from SDRAM (the mbed-core still needs some fixes unrelated to micropython).

stm32/boards: Swap FMC banks on ARDUINO_GIGA and ARDUINO_PORTENTA_H7.
a3100be 
Swap FMC banks to remap the SDRAM bank1 address to 0x60000000.  Arduino's
M4 firmware uses address 0x60000000 by default.  When the elf loader tries
to load that it will fail because by default NOR/PSRAM is mapped at that
address, not SDRAM bank1.  (Note that the region at 0xC0000000 has an XN
attribute by default, so switching the M4 firmware address will not work.)

Thanks! With this and some other changes to the Arduino side, we're now able to load M4 firmware to SDRAM and have it execute from there.
