[U-Boot-Users] UART test in the Uboot

Hi all,
Can anyone explain me what is done in POST for UART (in the file uart.c in post directory of uboot).
Or how the testing is done in that code?
I am using PSC (Programmable Serial Controller) as UART, so how can I modify the code for that.
Please help me.
Regards,
Yasotha Balan R

There is no file post/uart.c in the U-Boot source tree. There are cpu/mpc8xx/uart.c and cpu/ppc4xx/uart.c - which one are you referring to?
Or how the testing is done in that code?
May I repeat my request that you read the code? The comments are pretty clear to me. Please explain which specific parts of the comments or code are not clear enough.

You cannot. You will have to write a new test driver.
