If it is possible, I would like to have a configuration option, which
allows to use D-Cache as RAM not only on PXA25X, but also on PXA27X. I
propose to preserve status-quo for now and only use D-Cache as RAM when
it is explicitly configured so.

You mentioned in a separate letter, that config options need
documenting. This part is missing in my patch, and I'll fix this, if the
above is OK.
