I am not sure if it is a similar situation. But anyway, I am open to suggestions.

For this driver, the variable needs to be writable. I guess it wasn't a problem
for existing platforms which probably call this driver after relocation.

Does the SRAM code/data relocate to SDRAM? I don't want this variable to stay in
SRAM once u-boot relocates to normal memory.
