In-Reply-To: <1349456686-22736-1-git-send-email-mporter@ti.com> References: <1349456686-22736-1-git-send-email-mporter@ti.com> Message-ID: <1349456686-22736-4-git-send-email-mporter@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Subhasish Ghosh This patch modifies the sram allocator to allocate memory from the DA8XX shared RAM. Regression tested suspend/resume on AM180x EVM.
