Hello u-boot users:
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. 


Fixed cpu/ppc4xx/start.S for Epx Errata

- further corrects PPC440EPx errata 1.12: 440_33 by moving patch up in
