From 4ef7b373df330bc0ff037dc4792d373c9346375f Mon Sep 17 00:00:00 2001 From: Jeremy Kerr Date: Sun, 14 Feb 2010 07:13:47 -0700 Subject: of/flattree: Don't assume HAVE_LMB We don't always have lmb available, so make arches provide an early_init_dt_alloc_memory_arch() to handle the allocation of memory in the fdt code. When we don't have lmb.h included, we need asm/page.h for __va.
