From d01c08c9ae91c1526d4564b400b3e0e04b49d1ba Mon Sep 17 00:00:00 2001 From: "Mark A. Greer" Date: Sat, 3 Sep 2005 15:55:56 -0700 Subject: [PATCH] [PATCH] ppc32: mv64x60 updates & enhancements Updates and enhancement to the ppc32 mv64x60 code: - move code to get mem size from mem ctlr to bootwrapper - address some errata in the mv64360 pic code - some minor cleanups - export one of the bridge's regs via sysfs so user daemon can watch for extraction events Signed-off-by: Mark A.
