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 the external NOR defined by the board device tree to be the first qspi/ospi instance (not necessarily zephyr, flash-controller) Signed-off-by: Francois Ramu <francois.ramu@st.com>
Define the stm32 disco board configuration to set the STM32 XIP mode that will enable the MemoryMapped mode. See Kconfig of the stm32 soc. Signed-off-by: Francois Ramu <francois.ramu@st.com>

Prepare the boot/zephyr/flash_map_extended.c to support the stm32 MemoryMapped mode where the application is XiP from a external octo/quad flash memory
This is done by setting the CONFIG_STM32_MEMMAP flag which configures the octo/quad flash stm32 driver in MemoryMapped mode
Then the application which is built/linked/stored in slot1_partition of the external ospi-nor-flash/qspi-nor-flash NOR flash is identified by the MCU boot, loaded and executed on the external NOR.
