ARM: mx6: Change the FDT loading address to avoid overlaping
This patch fixes allow for the DeviceTree and initrd relocation fixing the boot of FSL 3.10.9-1.0.0-alpha kernel. This changes following boards: - mx6sabreauto - mx6sabresd - wandboard - udoo - nitrogen6x - cgtqmx6eval The reasoning, as explained by Hui Liu, is: ,---- | The FDT blob will be placed at DDR physical addr: 0x11000000. When Linux kernel | Boot up, it will decompress the compressed kernel image and place the decompressed | kernel image at the low end of the DDR memory and start running from it. If the | decompressed kernel image is bigger for example than 16M, it may over written the | fdt blob which u-boot loaded to the DDR memory @0x11000000 with fdt_addr=0x11000000 | | To expand the fdt_addr from 0x11000000 to 0x18000000, which can avoid the override | Since we will not likely have one kernel image larger than 128MB. `---- Signed-off-by: Otavio Salvador <otavio@ossystems.com.br> Acked-by: Stefano Babic <sbabic@denx.de>
