From c94472d4ad11c5b7d8cd527d136c198269d390fc Mon Sep 17 00:00:00 2001 From: Subhasish Ghosh Date: Fri, 5 Oct 2012 13:04:42 -0400 Subject: [PATCH] ARM: davinci: da850: changed SRAM allocator to shared ram. This patch modifies the sram allocator to allocate memory from the DA8XX shared RAM. Regression tested suspend/resume on AM180x EVM.
