In non-combined boot flow for K3, all the firewalls are locked by default until sysfw comes up. Rom configures some of the firewall for its usage along with the SRAM for R5 but the PSRAM region is still locked.
The K3 MCU Scratchpad for j721e was set to a PSRAM region triggering the firewall exception before sysfw came up. The exception started happening after adding multi dtb support that accesses the scratchpad for reading EEPROM contents.
The commit changes R5 MCU scratchpad for j721e to an SRAM region.
