Re: [Isl3893-devel] OpenEmbedded port for isl3893?

Nearly all toolchains and embedded SDK I have seen sucks. I have not
tried OE yet, and emdebian will probably be out during the next year.

Even the openwrt distrib sucks, since it is impossible to recompile from
sources for other platforms.

I will have a look this afternoon to see what it looks like.

It seems that some people of Prism54-softmac can read arm assembler.

Maybe I will send them one Netgear AP which I have here for development.

I think it is really possible to build a new kernel for isl, sinc you
can ignore the most difficult part, which is probably supporting MVC
and/or the softmac thing.
