Hi,

upon revisiting the PPC4xx UART driver, I stumbled (again) over the CONFIG_SERIAL_SOFTWARE_FIFO feature. As it seems this feature is only implemented for PPC4xx and is not used in any mainline board ports. Frankly I never really understood why such a "feature" should be used. So I'm asking if anybody is really caring for this feature. If not, I'll send a patch to remove this stuff completely.

Any comments?

Cheers, Stefan
