From de40614e92bf1b0308d953387b0cb9d3a5710186 Mon Sep 17 00:00:00 2001 From: Joonsoo Kim Date: Fri, 5 Apr 2013 03:16:51 +0100 Subject: ARM: 7694/1: ARM, TCM: initialize TCM in paging_init(), instead of setup_arch() tcm_init() call iotable_init() and it use early_alloc variants which do memblock allocation. Directly using memblock allocation after initializing bootmem should not permitted, because bootmem can't know where are additinally reserved. So move tcm_init() to a safe place before initalizing bootmem.
