Useful commands

See what Kconfig symbols are used in a platform

Find hex encoded binaries in coreboot

git grep -c '0x' | grep src/ | grep -v ':.\?.\?.$' | sort -n -k2 -t ':'

Find binary files in src tree

find src -type f -exec file -i '{}' \; | grep 'charset=binary' | grep -v 'x-empty'

run checkpatch on files

DIR=src/lib;for file in $(git ls-files | grep "${DIR}"); do util/lint/checkpatch.pl --file $file --terse; done
