Implement GCC code coverage analysis In order to provide some insight on what code is executed during coreboot's run time and how well our test scenarios work, this adds code coverage support to coreboot's ram stage. This should be easily adaptable for payloads, and maybe even romstage. See http://gcc.gnu.org/onlinedocs/gcc/Gcov.html for more information. To instrument coreboot, select CONFIG_COVERAGE ("Code coverage support") in Kconfig, and recompile coreboot. coreboot will then store its code coverage information into CBMEM, if possible. Then, run "cbmem -CV" as root on the target system running the instrumented coreboot binary. This will create a whole bunch of .gcda files that contain coverage information. Tar them up, copy them to your build system machine, and untar them. Then you can use your favorite coverage utility (gcov, lcov, ...) to visualize code coverage. For a sneak peak of what will expect you, please take a look at http://www.coreboot.org/~stepan/coreboot-coverage/ Change-Id: Ib287d8309878a1f5c4be770c38b1bc0bb3aa6ec7 Signed-off-by: Stefan Reinauer <reinauer@google.com> Reviewed-on: http://review.coreboot.org/2052 Tested-by: build bot (Jenkins) Reviewed-by: David Hendricks <dhendrix@chromium.org> Reviewed-by: Martin Roth <martin@se-eng.com> Reviewed-by: Ronald G.
