From da31d6fb46b7671622dbfd44c7f27b0c97dc2faa Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Mon, 27 Jun 2011 15:43:56 -0400 Subject: [PATCH] Blackfin: dpmc: don't save/restore scratch registers The Blackfin C ABI says we do not need to save/restore R0-R3 and P0-P2 as they are available as scratch registers. So don't bother.
