MPC8xx USB SOF microcode patch

Hello,

I am using linux 2.6.15 and try to get the MPC875 USB controller 
working. I just checked if the microcode patch in 
arch/ppc/8xx_io/micropatch.c for CONFIG_USB_SOF_UCODE_PATCH set 
corresponds with the newest microcode patch for mpc8xx, downloadable 
from freescale: They differ slighly, is it an older (working) version or 
where is it from ?

ciao
