Adding the support of the memoryMapped mode to the flash_stm32_xspi driver through the CONFIG_STM32_MEMMAP That will allow XiP from the external octo_flash Erase and Write operation must Abort operations. Signed-off-by: Francois Ramu <[email protected]>
Configure the external NOR flash memory to be executable. Change the board.cmake to add the external loader for flashing (version that do not mass-erase the external flash). The address of the external flash is not needed when flashing a hex file. Signed-off-by: Francois Ramu <[email protected]>
Define the configuration to run the code_relocation application on the external memory xspi flash of the stm32h573i_dk disco kit in XIP Signed-off-by: Francois Ramu <[email protected]>
Define the configuration to run the test on the external memory xspi flash of the stm32h573i_dk disco kit in MemoryMapped Mode Reading is done with memcopy and erase/write are aborting operation to send the appropriate command Signed-off-by: Francois Ramu <[email protected]>

Like the flash_stm32_qspi or flash_stm32_ospi drivers, this PR adds the Memory Mapped mode
so that code can eXecute In Place from the external NOR flash
This is validated on the stm32H5 serie and demonstrated on the stm32h573i_dk disco kit (Macronix MX25LM51245 octo-NOR ).
Running the samples/application_development/code_relocation_nocopy/ with CONFIG_STM32_MEMMAP=y
Requires #73220
