From a28899c910024a0226331df07207b1038c300c93 Mon Sep 17 00:00:00 2001 From: Emilian Medve Date: Tue, 30 Jan 2007 16:14:50 -0600 Subject: [PATCH] mpc83xx: Fix alternating tx error / tx buffer not ready bug in QE UEC The problem is not gcc4 but the code itself. The BD_STATUS() macro can't be used for busy-waiting since it strips the 'volatile' property from the bd variable. gcc3 was working by pure luck.
