Hello,
I am trying to port linux for my ppc board. There is no keybord and
no scree. There is only UART.
I would like to have a console/terminal using UART.
What is the best way ? to write a serial driver using "struct
uart_driver" or using "tty_driver" or to write a driver from scratch.
Maybe there is other way.
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).
