which driver for uartlite with 2.6.17?

[Robert Corley]

All,

Based on what was posted recently, it appears that there is more than one uartlite driver 
floating about.

Can someone please inform me of which driver works for which kernel?

Here is what I see

D. Lynch    2.6.15    polled, (Pico E12 board specific?)
P. Korsgaard    2.6.18    interrupt driven, official lanana.org nodes
D. Bolcsfoldi    2.6.18    interrupt driven

patch locations:

D. Bolcsfoldi    http://ozlabs.org/pipermail/linuxppc-embedded/2006-October/024697.html

Comments?

And, lastly, I need a driver for 2.6.17.  Can someone point me in the right direction?  
I have tried Peter's driver but it fails to compile, showing this:
