[U-Boot] [PATCH 0/2] pxa: fix memory coherency problem after relocation

[Mike Dunn]

These patches fix a memory coherency problem that sometimes occurs on xscale
after code relocation.  The first patch changes the options passed to the
compiler so that the __XSCALE__ macro is defined.  This is used in the second
patch to limit the change to xscale cores, where the necessary cache operations
are performed before jumping to the relocated code.

Whether other cores need a similiar operation after code relocation remains an
open question.

Thanks Albert.
