From e8fbcff2a43c4b911aac529c7f684bfbd6dad184 Mon Sep 17 00:00:00 2001 From: Jonas Aaberg Date: Wed, 28 Apr 2010 11:42:02 +0200 Subject: [PATCH 25/45] DMAENGINE: ste_dma40: arch updates for LCLA and LCPA This follows on the patch to allocate LCLA dynamically: the on-chip memory is needed for other things so now that that we're using it dynamically we can remove the LCLA resource altogether and free up some ESRAM memory.
