How to calculate the TCB size

Hi Jaemin,

Sorry for the delayed answer. Unfortunately, I overlooked your question.

By default we calculate our LOC values via 'sloccount <SRC_DIR>' called
for each source directory that is used. Of course, this way you have to
evaluate manually which sources (repos, components, libs, specs) are
used in your scenario. At least, I do not know a way to automate this
step. You may reduce the effort by lower requirements in accuracy. E.g.,
when compiling core for hw_panda you can simply count all in base-hw and
base to get an upper bound.

Cheers,
