Enable FSL_85XX_CACHE_SRAM selection. On e500 platforms, the cache
could be configured and used as a piece of SRAM which is hignly
friendly for some user level application performances.

Why make that user selectable ?
Either a kernel is 64-bit or it is 32-bit. So having PPC64 user
selectable is all we need.
And what is the link between this change and the description in the log ?

Why make this user-selectable ? This is already selected by the
processors requiring it, ie 8500, e5500 and e6500.
Is there any other case where we need E500 ?
And again, what's the link between this change and the description in
the log ?
