+Subject: [PATCH 3/6] MIPS: BCM47XX: detect some more Linksys devices
+
+The Linksys WRT54G/GS/GL family uses the same boardtype numbers, and
+the same gpio configuration. The boardtype numbers are changing with
+the hardware versions, but these hardware numbers are different or each
+model.
+Detect them all as one device, this also worked in OpenWrt.

+Add a few Belkin F7Dxxxx entries, with F7D4401 sourced from online
+documentation and the "F7D7302" being observed. F7D3301, F7D3302, and
+F7D4302 are reasonable guesses which are unlikely to cause
+mis-detection.
