[U-Boot-Users] [PATCH] sequoia uarts

[Steven A. Falco]

I have verified that the Sequoia (440EPx) does not have its UARTs
properly configured.  The attached patch corrects this by setting three
bits in SDR0_PFC1 to enable 4-wire mode, and to select cts/rts
functionality for the UARTs.  Also, I modified the GPIO settings for
pins 34-37 to conform to the tables in section 31 of the 440EPx users
manual.

Here is a dump of the registers once the patch was made.  I've verified
that these match the users manual.  Also, my Sequoia board works. :-)
