From dcdeeb21c010e9b5cb2e91f865cd5bebb65bc31f Mon Sep 17 00:00:00 2001 From: Imre Kaloz Date: Sat, 2 Jun 2007 15:47:51 +0100 Subject: [ARM] 4426/2: Netgear WG302 v2 and WAG302 v2 support This patch provides support for the Netgear WG302 v2 and WAG302 v2 AccessPoint series. This patch relies on the patch "Gateway 7001 series support" minimally, as they only have UART2 connected. Updated to stay below the 80 char limit in uncompress.h Signed-off-by: Imre Kaloz Signed-off-by: Deepak Saxena Signed-off-by: Russell King --- arch/arm/mach-ixp4xx/Kconfig | 8 +++ arch/arm/mach-ixp4xx/Makefile | 2 + arch/arm/mach-ixp4xx/wg302v2-pci.c | 64 ++++++++++++++++++ arch/arm/mach-ixp4xx/wg302v2-setup.c | 109 +++++++++++++++++++++++++++++++ include/asm-arm/arch-ixp4xx/uncompress.h | 2 +- 5 files changed, 184 insertions(+), 1 deletion(-) create mode 100644 arch/arm/mach-ixp4xx/wg302v2-pci.c create mode 100644 arch/arm/mach-ixp4xx/wg302v2-setup.c diff --git a/arch/arm/mach-ixp4xx/Kconfig b/arch/arm/mach-ixp4xx/Kconfig index daaa190c125..61b2dfcb89d 100644 --- a/arch/arm/mach-ixp4xx/Kconfig +++ b/arch/arm/mach-ixp4xx/Kconfig @@ -49,6 +49,14 @@ config MACH_GATEWAY7001 7001 Access Point.
