From ff1c0b6a795bce744527bc10c8268127ed818b42 Mon Sep 17 00:00:00 2001 From: Vineet Gupta Date: Tue, 15 Dec 2015 13:57:16 +0530 Subject: ARC: [plat-sim] unbork non default CONFIG_LINUX_LINK_BASE HIGHMEM support bumped the default memory size for nsim platform to 1G. Thus total memory ended at the very edge of start of peripherals address space. With linux link base shifted, memory started bleeding into peripheral space which caused early boot bad_page spew !
