# Temporary build locations:

# Extract source:

# 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 need a configuration file only so that we
# can build the tools:
make distclean
#make guruplug_config || exit 1
make tools-only_defconfig || failconfig

# Build:
echo "** Building tools **"
make $NUMJOBS tools || make tools || failmake
echo "** Building Env tools **"
make $NUMJOBS env   || make env   || failmake
make $NUMJOBS envtools || make envtools || failmake

# the package install script will take care of renaming it into place
# but you'll still have to manually uncomment the one line you need for
# 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.
