Subject: [PATCH] MPC8xxx: Define cache ops for USB
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit
This patch conditionally defines flush_dcache_range() and
invalidate_dcache_range() on MPC8xxx, to avoid EHCI complaining,
resulting in the following output:
$ ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- ./MAKEALL MPC8572DS
