What powerpc chip is this?  Most of the current SoC based chips 4xx/ 
8xx/8xxx should have UART drivers in existence already.  If this is  
something custom you are probably better of asking on the linux-kernel  
list this question since its not specific to PPC but just writing a  
driver.

(and I'm guessing the answer is uart_driver, but I haven't looked at  
what Alan Cox has been up to w/tty vs uart lately).
