A file called /lib/firmware/bcrm8011 is installed but it is 25k:

# ls -al /lib/firmware/brcm80211
-rw-r--r-- 1 root root 25617 Aug 28 00:00 /lib/firmware/brcm80211

and brcm80211/brcmfmac43455-sdio.clm_blob is missing.

Weirdly I can get to the correct blob by base64 decoding
lib/firmware/brcm80211 twice!

# base64 -d /lib/firmware/brcm80211 | \ 
base64 -d - > /lib/firmware/brcm/brcmfmac43455-sdio.clm_blob

# md5sum /lib/firmware/brcm/brcmfmac43455-sdio.clm_blob
c5aeca0e33de4ae870986c517963fef7  /lib/firmware/brcm/brcmfmac43455-
sdio.clm_blob

which matches the firmware shipped with raspbian.

I'm sorry but I don't know enough about binary patches in quilt to
figure out what went wrong.

Cheers,
Scott
