This signature is only valid for FSBL images. MCUBooot will sign images by itself. Signed-off-by: Erwan Gouriou <[email protected]>
- Provide external flash partition - Define external flash and flash controller - Define image as XIP as it will run from external flash - Defined flashing address depending on image (FSBL/Chainloaded) Signed-off-by: Erwan Gouriou <[email protected]>

Point to hal_stm32 change allowing to start chainloaded app (_s profile). Signed-off-by: Erwan Gouriou <[email protected]>
Make axisram2 which is used in fsbl mode available as well to chainloaded application in order not to loose 1M of RAM In order to avoid conflicts with bootloader, verify that code + ro data of the loaded application won't go further than bootloader start address. This is done with a linker assert. Signed-off-by: Erwan Gouriou <[email protected]>
Due to a BootROM clock switching issue, XSPI1 should use HCLK otherwise app won't restart on reset. Signed-off-by: Erwan Gouriou <[email protected]>

Set of required adaptations to allow running the zephyr image following a bootloader (mcuboot for now).
