The region is mapped at address "0x00000000" and has a size of 128KB, identical to the SRAM region size. This memory region is intended for loading a vbootrom image file as part of the boot process. The vbootrom region is initialized as ROM and registered in the SoC's address space using the ASPEED_DEV_VBOOTROM index.
