# Configure:
# An older ARM board - we aren't building u-boot for a specific 
# device (each device requires a specific version of u-boot with support for
# that device), we just need to configure it to be some sort of 'ARM' CPU
# so that we can build the u-boot tools.

# in /proc/cpuinfo -- if anyone wants to do this nicely (that does not involve
# including the data in the install script (instead all of the info is included
# in the sample file and sed is used to uncomment the correct one)) - let me know.
