ar71xx: add mac partition to the MR12/MR16
On the stock Meraki Firmare for the MR12/MR16, a chunk of SPI space after u-boot-env is used to store the boards Mac address. Sadly as this was removed on any device already on OpenWRT/LEDE, moving forward a new, 64k partition named "mac" will be used to store the mac address for the device (which is the minimum size). This allows users to properly set the correct MAC, without editing the ART partition (which holds the same MAC for all devices). The reason the space is taken from kernel instead of rootfs is currently kernels are only 1.3MB, so that way we can leave the current rootfs space alone for users who fully utilize the available storage space. Once this partition is added to a device, you can set your MAC doing the following: mtd erase mac echo -n -e '\x00\x18\x0a\x33\x44\x55' > /dev/mtd5 sync && reboot Where 00:18:0a:33:44:55 is your MAC address. This was tested, and confirmed working on both the MR12 and MR16. Signed-off-by: Chris Blake <chrisrblake93@gmail.com>
