From 46668df5d0a94c6f546bcd31bd56c0ded7b4193f Mon Sep 17 00:00:00 2001 From: Jagan Teki Date: Mon, 28 Aug 2017 16:45:47 +0530 Subject: [PATCH] i.MX6Q: spl: Fix falcon to use dram_init_banksize Memory dt node update introduced by spl_fixup_fdt() in below commit was making DDR configuration in-appropriate to boot falcon mode. Hence added dram_init_banksize for explicit assignment of proper base and size of DDR.
