In the interest of making long-term branch maintenance incur as little technical debt on us as possible, we should not maintain any files on the branch we are not actually using. This has the added effect of making it extremely clear when merging CLs from the main branch when changes have the possibility to affect us. The follow-on CL adds a convenience script to actually pull updates from the main branch and generate a CL for the update.

-This is the combined driver test. The goal is to have many driver test suites
-in one binary, so that compile time will be faster than many small tests, and
-so we can test interactions between different subsystems easily.
-
-## Run all the test suites
-
-```bash
-(chroot) zmake configure --test zephyr/test/drivers
-```
-
-To see all the output of zmake (for example if the build fails)
-
-```bash
-(chroot) zmake -l DEBUG -j 1 configure --test zephyr/test/drivers
-```
-
-## Code coverage
-
-To calculate code coverage for this test only
-
-```bash
-(chroot) zmake configure --coverage --test zephyr/test/drivers
-(chroot) lcov --gcov-tool ~/trunk/src/platform/ec/util/llvm-gcov.sh -q \
- -o build/zephyr/test/drivers/lcov.info -c -d build/zephyr/test/drivers
-(chroot) genhtml -q -o build/zephyr/test/drivers/coverage_rpt \
- build/zephyr/test/drivers/lcov.info
-```
-
-The report will be in build/zephyr/test/drivers/coverage_rpt/index.html
-
-## Debugging
-
-You need the host version of gdb:
-
-```bash
-(chroot) sudo emerge -j sys-devel/gdb
-```
-
-Build the test
-```bash
-(chroot) zmake configure --build zephyr/test/drivers
-```
-
-Then run gdb
-
-```
-(chroot) gdb build/zephyr/test/drivers/build-singleimage/zephyr/zephyr.exe
-# Set breakpoints, run, etc.
-```
