Booting an initramfs with the current initrd_addr address may lead to initramfs corruption and boot failure. Fix the initramfs problem by applying the following layout suggested by Tom Rini: loadaddr=0x40480000 --> Gets moved to 0x40600000 in run-time: Uncompressing Kernel Image Moving Image from 0x40480000 to 0x40600000, end=41e80000 fdt_addr_r= moved loadaddr + 128 MiB = 0x48600000 initrd_addr=fdt_addr_r + 512 KiB = 0x48680000 Signed-off-by: Fabio Estevam <festevam@denx.de> Tested-by: Stefano Babic <sbabic@denx.de> Reviewed-by: Tom Rini <trini@konsulko.com>
