Subject: [PATCH v4 3/7] ARM: davinci: da850: changed SRAM allocator to shared ram.
Date: Fri, 5 Oct 2012 13:04:42 -0400 [thread overview]
Message-ID: <1349456686-22736-4-git-send-email-mporter@ti.com> (raw)
In-Reply-To: <1349456686-22736-1-git-send-email-mporter@ti.com>
From: Subhasish Ghosh <subhasish@mistralsolutions.com>
This patch modifies the sram allocator to allocate memory
from the DA8XX shared RAM.
Regression tested suspend/resume on AM180x EVM.
Signed-off-by: Subhasish Ghosh <subhasish@mistralsolutions.com>
[rebased onto consolidated SRAM patches]
