I have a PPC405GPr based board w/ 128Meg SDRAM, and I'm building
kernel 2.4.24 (devel CVS) for it. I also have U-Boot ported to
it, and I'm using U-Boot as the bootstrap loader.
I am able to compile a uImage, load the uImage via SystemACE,
and bootm seems happy with it. (See bootm log below.) I'm able
to show that head_4xx.S gets as far as calling early_init in
setup.c, and I can show that it starts executing in setup.c,
but calls to reloc_offset never execute. It appears that the
reloc_offset function never even starts.
I believe the SDRAM is configured OK, as u-boot is running out
of it quite happily. So I'm left wondering what can possibly
