Dan,
A change made by you on April 15th breaks firmware downloading to an
sdio connected 8686 on the OLPC's XO-1.5s. I reverted it and was able
to get firmware to load just fine, with it in, the firmware fails to
load.

libertas: consolidate SDIO firmware wait code
Consolidate a bunch of C&P code that waits for the firmware to be ready.

I don't know if there's something unique with this device where
libertas_sdio works everywhere else and not with the XO-1.5, but I
suspect we'll encounter this issue with other libertas devices.
I apologize for not sending a patch, but I don't have time right now
to get to it. Perhaps you can get to it quicker, if so, I'll be happy
to test anything you come up with.
