> 
> The patch adds support for the MikroTik RB911-2Hn (911 Lite2)
> and the RB911-5Hn (911 Lite5) boards:
> 
>  https://mikrotik.com/product/RB911-2Hn
>  https://mikrotik.com/product/RB911-5Hn
> 
> The two boards are using the same hardware design, the only difference
> between the two is the supported wireless band.
> 
> Specifications:
>  * SoC: Atheros AR9344 (600MHz)
>  * RAM: 64MiB
>  * Storage: 16 MiB SPI NOR flash
>  * Ethernet: 1x100M (Passive PoE in)
>  * Wireless: AR9344 built-in wireless MAC, single chain
>              802.11b/g/n (911-2Hn) or 802.11a/g/n (911-5Hn)
> 
> Notes:
>  * Older versions of these boards might be equipped with a NAND
>    flash chip instead of the SPI NOR device. Those boards are not
>    supported (yet).[1]
>  * The MikroTik RB911-5HnD (911 Lite5 Dual) board also uses the
>    same hardware. Support for that can be added later with little
>    effort probably.[2]

> Known issues
> Compared to ar71xx target image, there is still small leak of current to

> to 0. The cause of that is still unknown.

> 2. RB911-5HnD should work with this commit or with [1], depending on
