HACK: Add script to build an image without portage
This script allows building a mandolin, trembyle, etc rom without
portage. This script must be run inside the chroot and from the
coreboot-zork directory.
Usage:
./build-fast trembyle mandolin-hardcore
*** Built /tmp/coreboot/trembyle/image-trembyle.serial.bin ***
*** Built /tmp/coreboot/mandolin-hardcore/image-mandolin-hardcore.serial.bin ***
The script utilizes a cache located in /tmp/coreboot so repeat builds
don't have to start from scratch.
./build-fast trembyle
real 0m4.420s
user 0m3.235s
sys 0m2.785s
BUG=none
BRANCH=none
TEST=Built a mandolin rom and trembyle rom. Verified trembyle rom boots
to OS.
