[OpenWrt-Devel] [PATCHv5] ramips: add support for SamKnows SK-WB8

[Andrew Yong]

"alternatively call uboot-env directly without the fw_* abstraction layer"

Pardon the obtuse question but how would I go about doing this? It
sounds like the cleanest way to do things.

I'd like to avoid calling uci-default earlier than it needs to be, and
potentially messing up other things in the init process.

If there really isn't an OpenWrt-approved way to do this, I may just
advocate replacing SamKnows' u-boot entirely (writing to the same
partition every boot seems bad for flash memory anyway).
