This driver needs a data structure in SRAM before SDRAM is available. This is not alway the case using .data section. Moving this data structure to global_data guarantees it is writable.

If you need something in SRAM then you need to place it in that section, see arch/arm/cpu/armv7/am33xx/u-boot-spl.lds for example
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.
