/*
 * How to add or update the tests:
 * Contributor:
 * 1. add empty files for new tables, if any, under tests/data/acpi
 * 2. list any changed files in tests/bios-tables-test-allowed-diff.h
 * 3. commit the above *before* making changes that affect the tables
 * Maintainer:
 * After 1-3 above tests will pass but ignore differences with the expected files.
 * You will also notice that tests/bios-tables-test-allowed-diff.h lists
 * a bunch of files. This is your hint that you need to do the below:
 * 4. Run
 *      make check V=1
 * this will produce a bunch of warnings about differences
 * beween actual and expected ACPI tables. If you have IASL installed,
 * they will also be disassembled so you can look at the disassembled
 * output. If not - disassemble them yourself in any way you like.
 * Look at the differences - make sure they make sense and match what the
 * changes you are merging are supposed to do.
 *
 * 5. From build directory, run:
 *      $(SRC_PATH)/tests/data/acpi/rebuild-expected-aml.sh
 * 6. Now commit any changes.
 * 7. Before doing a pull request, make sure tests/bios-tables-test-allowed-diff.h
 *    is empty - this will ensure following changes to ACPI tables will
 *    be noticed.
