[U-Boot-Users] PPC440GX reset command doesn't work

We have a custom PPC440GX board running a ported version of U-Boot based
on the OCOTEA codebase. Most U-Boot commands are working - life is good.

Except for the 'reset' command. The do_reset() source code at
cpu/ppc4xx/cpu.c appears to be the function for doing the reset via the
PPC "debug control register". The PPC manual shows that a cpu reset is
possible thru this register, but I'm a PPC assembly newbee and need to
figure it out the macros in the cpu.c source code.

Just wondering if anyone else with a PPC440 target had any special
modifications to make 'reset' work.

Thank you.
