This patch further corrects errata 1.12: 440_33. We came across a problem affecting around 20% of 440EPx processors in which it took multiple resets to start the processor after a cold power up. In resolving the problem, it was discovered that the above mentioned errata correction in the startup code in start.S was never reached. This patch resolves that problem by moving up the errata correction erlier in the code. One of our software engineers hypothesizes that this patch, store gathering & broadcast disable, must happen before doing a jump.
