Hi,

I've got working cross-build toolchain now.

IIRC virtera is commercial, no go.

Well, speed of my Internet connection can make ssh connection slow,
but if you have no time to do decompression of PCI fullmac or
softmac firmware (I'm most interested in those), let's do it.

Fullmac which is working for me is:
http://prism54.org/~mcgrof/firmware/1.0.4.3.arm

If you can't decompress fullmac, softmac version is your
pick, but it won't be as useful to me (I won't be able
to verify correctness of reassembly by running it).

Ultimately I want to have fullmac fw in the form of .s file
which I can compile, load into my card and have card working.
I need help in getting uncompressed binary image, rest
I will do myself (as I said above I already have objdump & as).
