No; the stuff in 2.6 is not integrated w/ platform studio.  (only 2.4
is).  However, you do need to extract the xparameters.h file from the
platform studio BSP.  You can generate a Linux BSP w/o actually
telling it where your Linux tree is.  Once its generated; pull out
xparameters.h and drop it into arch/ppc/platforms/4xx/xparameters/ in
your source tree.  Note: it's important that you generate a LINUX BSP;
not a 'standalone' bsp.  If you don't, then you'll be missing a bunch
of #defines.

Let me say that once more for clarity: The only file you need from
platform studio is the generated xparameters.h

This will give you at the very least a serial port driver.  Once your
booting with that, you can focus on other device drivers.

Trust me; this is the path of far less pain.

Cheers,
