compiling kernel 3.1 using buildroot touch doesn't works...

Hello all,
I'm compiling the buildroot 2011.11 to generate rootfs + kernel for a
mini2440, using default settings it generates u-boot OK, kernel OK and fs
OK - the board boots and show login on serial terminal, but the board
doesn't works the the 7'' touchscreen and SPI system, after some search  I
found that the vanilla kernel doesn't has the code to manage the
touchscreen and SPI subsystem.

I want to know if someone can run kernel 3.1.4 (version compiled in
buildroot) withou these problems, and/or if exists some place on the net
with the patches to run Linux OK on mini2440, these patches can be to
kernel 2.6 too.

Thanks for all 
Flavio

In my experience the only effective way is to use the Pengutronix mini2440
BSP or learn how to do these patches yourself. Have a look in their patch
directory.

You will find a SPI "patch" on buserror's site and that is one I am
up-dating for the above BSP.

Many patches for the mini2440 never worked their way to inclusion in the
mainline kernel.

Good luck!
