[PATCH 5/7] bsps/stm32h7: add configuration and enable build of stm32h757i-eval-m4 BSP

Karel Gardas karel at functional.vision
Sun May 29 23:36:06 UTC 2022 

This is minimalist configuration for the stm32h757i-eval-m4 BSP provided
here. The only general enhancement worth mention is a flash origin address
configuration which is needed for simplification as M4 core boots
from second flash bank which starts at 0x8100000 by default. The boot
address of the core may be changed by using STM32CubeProgrammer. If done
so then also BSP configuration needs to be changed accordingly.

As the BSP variant is running on M4 core, there is also more configuration
changes required here. E.g. boot core and ABI (compilation flags)
in comparison with stm32h757i-eval BSP. On the other hand, C code is shared
completely with this BSP variant.
