nRF7120 builds without Partition Manager, where BOOT_MAX_IMG_SECTORS_AUTO is enabled by default and derives the sector count from the DTS slot size and the MRAM erase-block. Enable link-time optimization (CONFIG_LTO and CONFIG_ISR_TABLES_LOCAL_DECLARATION) to reduce the MCUboot footprint. Enable FPROTECT. Signed-off-by: Erdem Simsek <erdem.simsek@nordicsemi.no>
Generalize the self-RWX lock for nRF71 and nRF54 series devices. Signed-off-by: Erdem Simsek <erdem.simsek@nordicsemi.no>

new procedure should works - it now uses stack, although it is moved before stack reconfiguration.
Original procedure was sackless - so it was not the case.
