From b8f0d861152439b4f8c6304c4f556cfd5317ee77 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Wed, 4 Jan 2012 21:13:54 +0000 Subject: [PATCH] ar71xx: add inital support for the ALFA Network AP96 board The microSD slot and the Real Time Clock is not working yet. The miniPCIe interface is not tested due to the lack of a suitable card.
