The 'allmodconfig' is what we run, and it chose
#
# Platform support
#
CONFIG_PPC=y
CONFIG_PPC32=y
CONFIG_6xx=y

#
# IBM 4xx options
#
CONFIG_EMBEDDEDBOOT=y
CONFIG_8260=y
CONFIG_PPC_STD_MMU=y
CONFIG_SERIAL_CONSOLE=y
# CONFIG_EST8260 is not set
# CONFIG_SBS8260 is not set
# CONFIG_RPX6 is not set
# CONFIG_TQM8260 is not set
CONFIG_WILLOW_1=y

I had to change this to do TQM8260 because the header file willow.h is
missing and the number of errors for this one file made the compile look
far worse than it actually was.  If you suggest something, I will
change it.

I also realize that my output should include any changes I make to the
configurations and have that changed right away.

We are also adding the 'allyesconfig' and will apply the same platform
changes as to 'allmodconfig'.

Thanks;
