I'm ready to work a bit more than just compiling the kernel and run it on MPC5554.
On my target system there is a possibility to use external RAM connected to the
External Bus Interface, so I don't see this would be a problem in my case.

However, I have not much experience running Linux on PowerPC environment. Could
you suggest a PowerPC port which would be a good starting point to make support
for MPC5554?

As far as I could find out I'll need to create a device tree as documented in
the linux/Documentation/powerpc/booting-without-of.txt file.
