This test suite helps you keep track of different versions of u-boot/build tools, static analysis of that build’s binaries, and runtime trace results of running that binary on a given hardware configuration. For each u-boot/build configuration it keeps a database of information it statically gathered for each boot stage, boot stage images/ELF files, a prepared SD card image, and test results of runtime trace analyses. If it detects changes in the u-boot source or build tools it will create a new set of test result directories with a new sdcard image and static analysis results.[…]
