Probably your port of U-Boot is broken.

This is correct. U-Boot uses polling drivers.
the serial clks or the driver itself? Has anyone used SMC2 as the serial driver in the U-boot code. I was comparing the getc function of smc_serial.c and uart.c, one is using the while loop to wait and the other is using the for loop to wait, does it make a difference. Can anyone tell me what is going on?
We used SMC1 and S<C2 on quite a lot of boards. No problems ever.
