From 25d4eb8091f4c410987c139161d3621e0fb1fbca Mon Sep 17 00:00:00 2001 From: Masahiro Yamada <yamada.masahiro@socionext.com> Date: Sat, 9 Jan 2016 02:12:27 +0900 Subject: [PATCH] ARM: uniphier: add bootm_low environment The load address of the kernel can be changed via "kernel_addr_r" environment. The device tree and the initramdisk should be relocated according to the kernel location. The "bootm_low" should be calculated by masking the lower bits (TEXT_OFFSET part) of the "kernel_addr_r" environment value.
