The concept of PPC_HIGH_BATS is already some what handled with
CPU_FTR_HAS_HIGH_BATS.  I recommend you use this feature instead of
introducing another one as well as a compile time option.
CPU_FTR_HAS_HIGH_BATS only clears the high bats, but does
not attempt to use them. My patch will use them.
I understand, I'm suggesting you expand CPU_FTR_HAS_HIGH_BATS to
include your additional functionality.
How do you mean that exactly?

Do you mean making the feature always-on (not selectable in Kconfig)?
Having CONFIG_PPC_LARGE_BATS and CONFIG_HIGH_PATS always-on would
be ok for me, but for PHYS_64BIT should be left up to the platform
to decide if it should be presented to the user or not.
Yes, I think just making support for BATS 4-7 always on and use  
CONFIG_FTR_HAS_HIGH_BATS for any runtime fixup.
Do you think the other two features, CPU_FTR_BIG_PHYS and
CPU_FTR_LARGE_BATS should be merged into one bit? They could for now,
because there is no processor supporting only one of them.
Yes, this should still be a config option.  Merging  
CPU_FTR_LARGE_BATS into CPU_FTR_BIG_PHYS should be ok.
