ar71xx: add preliminary support for Mikrotik RB2011L
This patch adds preliminary support for the Mikrotik RB2011L. The NAND flash is not yet supported, so only the initramfs kernel can be used for now. [juhosg: remove unnecessary PCI/USB related stuff, the board does not use that, update commit message] Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@33344 3c298f89-4303-0410-b956-a3cf2f4a3e73
