Suresh,

This erratum only applies to LS1043A, LS1046A, LS2080A. It wouldn't be 
too much trouble to verify all of them. I'd rather we do it right at the 
first place than coming back to fix it. Are you in a rush to get this 
patch out?

Another thing, please drop defined(CONFIG_ARCH_LS2085A) for all the 
patches. We only use CONFIG_ARCH_LS2080A.
