From fcfa696b3a354ab1e16601683c61f671487aded7 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Thu, 28 Jun 2012 03:54:11 +0000 Subject: [PATCH] ARM: increase lmb stack space reservation to 4KB The bootm initrd image copy to ram can collide with the stack in cases where the print buffer size is large (i.e. 1K). The result is intermittent initrd decompression errors depending on the initrd size MOD 4KB since the initrd start address is 4KB aligned.
