Please use bootm_size and see include/configs/ti_armv7_common.h / DEFAULT_LINUX_BOOT_ENV for the why/wheres and then adjust to fit UniPhier, thanks!

I noticed "bootm_size" and "bootm_low" environments are checked for relocation for FDT, but not for Initramdisk. Namely, "initrd_high" is only the way to prevent the initramdisk from going too high. So, I posted this patch: http://patchwork.ozlabs.org/patch/558077/

With FIT boot, U-boot puts a device tree and an initramdisk at the tail of the memory. Some UniPhier boards have a large amount of memory. For those boards, a device tree and an initramdisk are located out of reach of the Linux kernel causing a kernel panic if CONFIG_VMSPLIT_3G is defined in the kernel side. Add initrd_high and fdt_high to prevent them from going too high. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> --- include/configs/uniphier.h | 2 ++ 1 file changed, 2 insertions(+)
