SUMMARY = "Nuvoton NPCM8XX bootloader"
DESCRIPTION = "This is front end recipe for NPCM8XX IGPS. It replace \
original IGPS recipe which need implement many redundant function in \
recipe or class. After we add some hook in IGPS, now we can generate \
full bootbloader by IGPS script. We only need collect all built images \
from deploy folder, put them to IGPS input folder, and run script."
