From 0a93ebef698b08ed04af0d7d913bab8aedfdc253 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Mon, 31 Oct 2011 17:08:16 -0700 Subject: memblock: add memblock_start_of_DRAM() SPARC32 require access to the start address. Add a new helper memblock_start_of_DRAM() to give access to the address of the first memblock - which contains the lowest address. The awkward name was chosen to match the already present memblock_end_of_DRAM(). Signed-off-by: Sam Ravnborg Cc: "David S. Miller" Cc: Yinghai Lu Acked-by: Tejun Heo Cc: "H.
