Not sure what you like to do, but be aware that you can only use the
third UART on this SoC without auto flow contol as nRTS2 and nCTS2 are
The data sheet for this SoC is available on the samsung website.
Chapter 11 tells you everything about the UARTs.

Don't invest work in such a old kernel. Nobody will help you with
problems on obsolete kernels. And also think about all the bugs that
were fixed for this hardware in newer kernels.
