[ELDK] udbg and early debug support for MPC5200

[Chris Alfred]

We have built a custom MPC5200B board similar to the Lite5200b. u-boot 
works fine, but we do not get any serial output when we transfer to 
the linux kernel.

We invoke the kernel with console=ttyPSC0,115200

So I tried setting up early debug based on:
http://www.mail-archive.com/linuxppc-dev@lists.ozlabs.org/msg22667.html

Unfortunately, this will not compile with the latest denx kernel git - 
ioremap_bat and most of the of_ functions in mpc52xx_udbg_init are 
unresolved.

Has anyone got a patch that works with the latest kernel git?


Argh! It's frustrating that the kernel structure keeps changing.
