Subject: pxa: Disable dcache on palmld, palmtc, zipitz2
X-Git-Tag: v2013.01-rc3~9^2~27
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=899590816a498beb771bc85f96a019cc91bcab3d;p=oweals%2Fu-boot.git

pxa: Disable dcache on palmld, palmtc, zipitz2

These platforms don't include dcache support. Define CONFIG_SYS_DCACHE_OFF
so that functions don't try to call non-existent routines like
flush_dcache_range().
