The previous commit ("add a new command to show .config contents")
improves the basic infrastructure of "embed a compressed file into
the U-Boot image, and print it by a command". The same pattern for
the "license" command.
This commit reworks the command to improve the following:
[1] Improve log style
Kbuild style log
GZIP cmd/license_data.gz
CHK cmd/license_data_gz.h
UPD cmd/license_data_gz.h
CHK cmd/license_data_size.h
UPD cmd/license_data_size.h
instead of the bare Make log:
cat ./Licenses/gpl-2.0.txt | gzip -9 -c | \
tools/bin2header license_gzip > ./include/license.h
[2] Collect related code into the "cmd" directory
Prior to this commit, the license.h was created by tools/Makefile,
placed under the "include" directory, included from cmd/license.c,
and deleted by the top-level Makefile. It is not a good idea to
scatter related code.
[3] Drop the fixed-malloc size LICENSE_MAX
Just allocate the minimum required size of buffer because we know
the size of the original gpl-2.0.txt.
[4] Fix more issues
Terminate the buffer with zero to prevent puts() from over-running.
Add "static" to do_license.
