From 39bdaff4f4dd75b578c9e1fe372e8d56e7d51526 Mon Sep 17 00:00:00 2001 From: Ruchika Gupta Date: Mon, 25 Mar 2013 07:40:25 +0000 Subject: SECURE BOOT - Removed deletion of TLB entries code Boot ROM code creates TLB entries for 3.5G space before entering the u-boot. Earlier we were deleting these entries after early initialization of CPU. In recent past, code has been added to invalidate all these entries before relocation of u-boot code. So this code to delete TLB entries after CPU initialization is no longer required.
