# Temporary build locations:

# Versions:
SHEEVATOOLSVER=09.04.2010

# Extract source:

cd u-boot* || exit 1
# Add some Debian source to obtain some default env configs and extra man pages:

# Configure:
# 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.

# the specific board you're using.  This could be done automatically by looking
# 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.
