When I try check wifi chip RT2870, It is still not work completely.
Anyway Fire:88W8686 needs ANTENNA even 30cm radius from AP.
And headache cross compile RT2870.
Change Makefile like that,Hope it will help for another too.
I used bitbake, So better use that tool chain for cross compile. Because bitbake already gitted kernel headers and build tool chain.
For example, little change RT2870's Makefile.
in ~/tmp/work dir there is source for build and ~/tmp/cross dir there is Tool chain.
But end of line should be "arm-angstrom-linux-gnueabi-", compiler will attach on that end.

'HAS_WPA_SUPPLICANT=y' and 'HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=n'
that version doesn't work in arm... still I am testing.
