From 347d120a63e612b3e959a1982b15c3e79412e653 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Fri, 11 Feb 2011 19:05:30 +0000 Subject: [PATCH] gas: blackfin: docs: typo fixes and fill out directive info A bunch of Blackfin-specific directives were lacking info on what they actually do, so fill in the blanks. Further, the byte2/byte4 descriptions were swapped.
