Hello,


As long as we have <mach/asv.h> in our hands, we can have the ASV
value stored at the common place declared by this asv.h rather than at
INFORM2 as I've mentioned before at another thread. This location
<mach/asv.h> seems the perfect location for the purpose. Besides, now,
with Exynos4x12s, I start to hear cases where all the INFORMx
registers are fully used; thus, it seems that it's time to remove
unnecessary usage of the registers.



Cheers!
