From 7ff7166c55c67b2e567e4cbf4a934cdf0d41ea5b Mon Sep 17 00:00:00 2001 From: Alison Wang <b18965@freescale.com> Date: Mon, 26 Oct 2015 14:08:28 +0800 Subject: [PATCH] arm: ls102xa: Set fdt_high and initrd_high to the value of 0xffffffff As 3G/1G user/kernel memory split is used on LS1021A, the Linux kernel fails to access the device tree blob on boot. The reason is that u-boot relocates the device tree blob into high memory when booting the kernel and the kernel is unable to access the blob. To avoid this issue, fdt_high is set to the value of 0xffffffff. The device tree blob will not get relocated and is still in low memory to make it accessible to the kernel. For the same reason, initrd_high is set to the value of 0xffffffff too.
