[microblaze-uclinux] Xilinx XPS USB Host controller with petalogix?

[hoefle marco <marco.hoefle@xxxxxxxxxxxxx>]

Hello,
I want to evaluate the Xilinx USB Host Controller available in EDK 11.x
together with petalinux. I have a mmu-less Microblaze test design
containing a the XPS USB Host controller on a Spartan3A Starter Kit.
If the Host controller works it would give a whole lot of opportunities
to a system.
The plan is either to use the Kernel pulled from git://git.monstr.eu/,
compiling it with the microblaze-uclinux- toolchain or to extract the
USB drivers from the Kernel sources and compile them as a module for the
standard petalogix kernel.

Has anyone recommendations in terms of:
- Is it possible to use the kernel 2.6.3x.y without mmu and the uclinux
toolchain?
- Will it be a lot of effort to backport the USB to the petalogix kernel
2.6.20?
- has anyone already used the XPS USB Host controller?

Thanks,
Marco
