From 6584a1b52624d60249c3d5115b176315dbac3939 Mon Sep 17 00:00:00 2001 From: Otavio Salvador Date: Mon, 16 Dec 2013 20:44:04 -0200 Subject: 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 Acked-by: Stefano Babic --- include/configs/udoo.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'include/configs/udoo.h') diff --git a/include/configs/udoo.h b/include/configs/udoo.h index 4d96f18b08..614e1fe3b5 100644 --- a/include/configs/udoo.h +++ b/include/configs/udoo.h @@ -106,7 +106,7 @@ "fdt_high=0xffffffff\0" \ "initrd_high=0xffffffff\0" \ "fdt_file=" CONFIG_DEFAULT_FDT_FILE "\0" \ - "fdt_addr=0x11000000\0" \ + "fdt_addr=0x18000000\0" \ "boot_fdt=try\0" \ "ip_dyn=yes\0" \ "mmcdev=0\0" \ -- cgit v1.2.1
