Therefore the board specific name mgcoge was renamed to a generic name km82xx. Additionally some enhancements were made: - rework partition table in dts file - add cpm2_pio_c gpio controller in dts file - update defconfig - add pin description for SCC1 - add pin description and configuration for USB Signed-off-by: Holger Brunck Acked-by: Heiko Schocher CC: Benjamin Herrenschmidt CC: Heiko Schocher Signed-off-by: Kumar Gala --- arch/powerpc/boot/dts/mgcoge.dts | 47 ++++---- arch/powerpc/configs/mgcoge_defconfig | 9 +- arch/powerpc/platforms/82xx/Makefile | 2 +- arch/powerpc/platforms/82xx/km82xx.c | 206 ++++++++++++++++++++++++++++++++++ arch/powerpc/platforms/82xx/mgcoge.c | 180 ----------------------------- 5 files changed, 234 insertions(+), 210 deletions(-) create mode 100644 arch/powerpc/platforms/82xx/km82xx.c delete mode 100644 arch/powerpc/platforms/82xx/mgcoge.c (limited to 'arch/powerpc/platforms/82xx') diff --git a/arch/powerpc/boot/dts/mgcoge.dts b/arch/powerpc/boot/dts/mgcoge.dts index 0ce96644176d..1360d2f69024 100644 --- a/arch/powerpc/boot/dts/mgcoge.dts +++ b/arch/powerpc/boot/dts/mgcoge.dts @@ -13,7 +13,7 @@ /dts-v1/;
