boot: zephyr: defines FLASH device for external NOR (cde66e17) · Commits · Wenxi XU / Mcuboot

With CONFIG_STM32_MEMMAP flag get NOR flash 32 bytes header Read the NOR flash to get header of the image. The FLASH_DEVICE is now given by the parent of the "st,stm32-xspi-nor" node, which is the "st,stm32-xspi" compatible same for qspi/ospi instances of stm32 devices. Signed-off-by:
