I finally managed to get a booting linuxppc-2.4 kernel and some console
output.  Now onto getting a working rootfs...

For reference in case anybody tries this at home, the problems were:

1) arch/ppc/platforms/rpx8260.h defined it's own bd_info structure which
was not consistent with u-boot.  This caused the time settings to be
wrong, which in turn caused the decrementer to be set to zero... "That's
it man, game over man, game over, man!"

2) drivers/char/tty_io.c has a typo on the CPM2 support in
console_init() that prevents it from working with anything but 8xx

- #if defined(CONFIG_8xx) || defined(CONFIG_CONFIG_CPM2_UART)
+ #if defined(CONFIG_8xx) || defined(CONFIG_CPM2_UART)
