Problem bringing up Linux on Custom MPC522 Board

["Chris Down" <chris@alcor.co.uk>]

I am trying to bring up Linux (latest linuxppc-2.4 tree) on a custom =
MPC852
Board. The board has 8MByte SDRAM and 8MByte Flash.=20
I have ported u-boot, modified Linux to add a new board config and added =
the
board specific definitions in arch/ppc/platforms.=20
U-Boot and Linux were built using the ppc_8xx compiler from ELDK 3.0.

When I boot Linux I get the following:-

## Booting image at 00100000 ...
   Image Name:   Linux-2.4.28-pre3-cdd1
   Image Type:   PowerPC Linux Kernel Image (gzip compressed)

POSIX conformance testing by UNIFIX

At this point it stops executing in arch_kernel_thread.

As I am new to this I could do with some pointers as to what to do next. =
Any
help would be gratefully appreciated.
