From: Joe Komlodi <koml...@google.com> cde3247651dc998da5dc1005148302a90d72f21f fixed atomicity for LDRD, which ends up making accesses 64-bits wide. However, the AST2600 bootloader can sometimes compile with LDRD instructions, which causes the acceses to fail when accessing the memory-mapped SPI flash.
To fix this, increase the MMIO region valid access size to allow for 64-bit accesses.
