We use CONFIG_SYS_RAMBOOT for when boot out of NAND, SPI, SDHC/MMC
and utilize a L2 or L3 cache in SRAM mode. In this case we will
end up changing the cache from SRAM mode back to cache before we
relocate the environment properly in env_relocate().
So we need to manual relocate the env pointer out of SRAM into DDR.
