[OpenWrt-Devel] [PATCH v3 0/3] x86: upgrade bootloader on sysupgrade

[Tomasz Maciej Nowak]

After gotten bit more familiar with OpenWrt, I found less intrusive
method to implement upgrading of bootloader, instead of rewriting image
generation code like in my previous attempt [1]. It had some value in
itself, so if anyone will request it, I'll respin these patches as
separate series in near future.

To expand a bit the explanation "Why this series?", please consult [2]
and the conversation in that letter.
