Subject: [PATCH] ARM: mach-shmobile: Set CONSISTENT_DMA_SIZE to 158 MB
Date: Wed, 28 Apr 2010 08:25:30 +0000 [thread overview]
Message-ID: <20100428082530.29018.50464.sendpatchset@t400s> (raw)
From: Magnus Damm <damm@opensource.se>
This patch sets CONSISTENT_DMA_SIZE to 158 MB
for all SH-Mobile ARM processors.
The DMA area is mapped at 0xf6000000 - 0xffdfffff,
on top of the 256 MB I/O window at 0xe6000000.
