From 70fdbefc6c50010cc56196b65a233369d2b2ce68 Mon Sep 17 00:00:00 2001 From: Amit Virdi Date: Mon, 7 May 2012 13:06:40 +0530 Subject: [PATCH] SPEAr: Eliminate dependency on Xloader table Xloader table was used primarily to inform u-boot about the DDR size. However, now the ddr size is calculated at runtime which eliminates any need for the Xloader table. So removing this unnecessary code.
