This patch adds initial support for the Aztech HW550-3G (Ralink RT3052f SoC, 8MB flash, 32MB dram). Ethernet is not working yet. Wireless appears to work fine. USB does not work yet (as with other Ralink boards). Signed-off-by: Layne Edwards <ledwards76@gmail.com> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@26123 3c298f89-4303-0410-b956-a3cf2f4a3e73
