Supporting a PS/2 Keyboard

Hi everyone,

Is it possible to have a PS/2 keyboard connector interfaced directly to
the Intel PXA270 (via GPIO pins) and leverage the existing KeyBD driver
to get scan codes from the keyboard? Obviously there's not an 8042
keyboard controller in the chain so I don't know if its possible to do
this. We have an application which basically is supposed to grab the
raw codes from the keyboard and passes them over a serial connection to
another application.

I'd appreciate any comments or suggestions any of you may have on this.

Thanks.
