I’ve searched and found some threads, but it’s still not clear to = me. I’m working on 405 with powerpc and trying to get UART550 = working.

I know that I need speed, freq, and reg-shift properties in the device = tree and I have found patches for of_serial.c.

I still don’t understand when to use of_serial.c = (SERIAL_OF_PLATFORM) vs the legacy support for serial ports. Is there any docs that = I’m not finding that I should read?

I don’t see a way to configure in the legacy support, but I’m using = SERIAL_OF and having problems. I don’t see the console getting enabled even = though it found the serial port driver.

Thanks,

John
