first thanks for your patch.
I tried it on my BF548 board today. Well, it basically did not change
the general behaviour.
Kernel Timer Tick set to 1000Hz - works at 11MBit/s.
But set to the default 250Hz (default for Blackfin) performance goes
down to 3MBit/s again.
Maybe there is an issue in the Blackfin SDIO Driver and not in
libertas? Not sure...
