THe traball is a snapshot from the linuxppc_2_4_devel CVS  tree  (for
ELDK  3.1.1  the  date  of  the  snapshot  is  2005-03-06  or CVS tag
LABEL_2005_03_06_0100).

PPCBoot 0.9.2 and U-Boot 1.1.2 are about 4 years apart. This is  like
comparing Linux kernel versions 2.0 with 2.6 ....

Both versions were perfectly  capable  of  booting  a  working  Linux
kernel. I don't know the MV toolchain, but I guess it's working fine,
too.  So my guess is that it's your port of the Linux kernel which is
broken.

Your port of the Linux kernel is broken.  Probably  you  made  errors
when changing the configure scripts and/or Makefiles.

You cannot do that. It does not work.

The _res pointer can be used for that; see the existing driver sources.

This depends on how your hardware and your port of Linux support such
a feature. I cannot answer such a question.
