From e275e023aa69bdc6a2f43b86ca3aa93a22e47837 Mon Sep 17 00:00:00 2001 From: Sean MacLennan Date: Fri, 9 Jan 2009 18:20:11 +0000 Subject: [PATCH] powerpc/44x: Warp patches for the new NDFC driver Convert the Warp platform to use the newly merged NDFC driver - warp.dts changed to work with ndfc - warp-nand.c no longer needed - removed obsolete rev A support from cuboot-warp.c Signed-off-by: Sean MacLennan Signed-off-by: Josh Boyer --- arch/powerpc/boot/cuboot-warp.c | 43 ----------- arch/powerpc/boot/dts/warp.dts | 42 +++++++++- arch/powerpc/platforms/44x/Makefile | 1 - arch/powerpc/platforms/44x/warp-nand.c | 135 --------------------------------- 4 files changed, 41 insertions(+), 180 deletions(-) delete mode 100644 arch/powerpc/platforms/44x/warp-nand.c diff --git a/arch/powerpc/boot/cuboot-warp.c b/arch/powerpc/boot/cuboot-warp.c index 2178021..806df69 100644 --- a/arch/powerpc/boot/cuboot-warp.c +++ b/arch/powerpc/boot/cuboot-warp.c @@ -18,57 +18,14 @@ static bd_t bd;
