From 83a92529c1789f86481190743a6bb09f31ec39a8 Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Mon, 19 Dec 2011 13:46:35 +0100 Subject: microblaze: mm: Fix lowmem max memory size limits Use CONFIG_LOWMEM_SIZE if system has larger ram size. For system with larger ram size, enable HIGMEM support. Also setup limitation for memblock and use memblock allocation in lowmem region.
