From: Biwen Li <[email protected]> The MCU firmware copies the rsc table to a fixed address (0x1FFF8000) at startup. However, this address is occupied by variables used in the MCU firmware, so copying the rsc table there corrupts those variables. Move the rsc-table reserved memory region from 0x1FFF8000 to 0x20000000 to avoid the conflict. The M33 firmware linker script has been updated accordingly to place the rpmsg resource table at 0x20000000 (DTCM m_rsc_tbl region).
