Unable to read or write from system SPI flash memory.

[AKASH G J]

I flashed OpenBMC image to system flash using pflash. After power-off, I
tried to boot the BMC (Aspeed AST-2500) from the system flash. For that I
used the command *bootm <system flash address>* in u-boot prompt. That
gives error "no image found".
