Hi,

Ken Ma found few issues in the driver. I wrote the first fix is based
on his report and the second one was written for U-Boot but as they
use the same driver it can be applied on linux too.

thanks,

Gregory

From: Ken Ma <make@marvell.com>

If north bridge selection register bit1 is clear, pins [10:8] are for
SDIO0 Resetn, Wakeup, and PDN while if bit1 is set, pins [10:8]are for
GPIO; when bit1 is clear, pin 9 and pin 10 can be used for uart2 RTSn
and CTSn, so bit1 should be added to uart2 group and it must be set
for both "gpio" and "uart" functions of uart2 group.

The sdio_sb group is composed of 6 pins and not 5.
