From 305b90919ea8c17edeb1e7d15ae5ca43f36bddc2 Mon Sep 17 00:00:00 2001 From: Peter Griffin Date: Wed, 20 Apr 2016 17:14:02 +0100 Subject: ARM: hisilicon: hikey: Align memory node with upstream kernel The memory node gets automatically generated by U-Boot in arch_fixup_fdt(), before passing control to the kernel using U-Boots representation of the dram banks. However the upstream kernel uses the memory node to carve-out regions of RAM for various purposes. To make this work without changing arch_fixup_fdt() which will effect many platforms we replicate the upstream memory node layout using the dram banks.
