[U-Boot] SA1110 Uart3 Weirdness

Greetings,

An update on the blob vs u-boot problems Im having. I noticed that driving UART3 > 19200
on blob caused the same kind of issues that Im seeing in u-boot. 
But downgrading baud = 19200 works in u-boot, but when booting kernel
I instead get scrambled data (which looks like wrong baud). Ive double checked so
the kernel in itself is using 19200 (hardcoded command line).

Since no one is using u-boot with an sa1110 + sa1111 platform its quite hard to
get any ideas about this. So suggestions are very welcome.

The memory, pin settings are all the same on both bootloaders

Best wishes
Kristoffer
