dcdeeb21c0
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 <kaloz@openwrt.org> Signed-off-by: Deepak Saxena <dsaxena@mvista.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
