dm: sandbox: Switch over to using the new host uclass

2022-11-07T23:24:30+00:00

Update the sandbox implementation to use UCLASS_HOST and adjust all
the pieces to continue to work:

- Update the 'host' command to use the new API
- Replace various uses of UCLASS_ROOT with UCLASS_HOST
- Disable test_eficonfig since it doesn't work (this should have a unit
  test to allow this to be debugged)
- Update the blk test to use the new API
- Drop the old header file

Unfortunately it does not seem to be possible to split this change up
further.

dm: blk: Tidy up obtaining a block device from its parent

2022-11-07T23:24:30+00:00

This function now finds its block-device child by looking for a child
device of the correct uclass (UCLASS_BLK). It cannot produce a device of
any other type, so drop the superfluous check.

Provide a version which does not probe the device, since that is often
needed when setting up the device's platdata.

Also fix up the function's comment.

test: Add a way to detect a test that breaks another

2022-11-07T23:24:30+00:00

When running unit tests, some may have side effects which cause a
subsequent test to break. This can sometimes be seen when using 'ut dm'
or similar.

Add a new argument which allows a particular (failing) test to be run
immediately after a certain number of tests have run. This allows the
test causing the failure to be determined.

Update the documentation also.

test: Allow showing basic information about tests

2022-11-07T23:24:30+00:00

Add a 'ut info' command to show the number of suites and tests. This is
useful to get a feel for the scale of the tests.

test: Tidy up help for ut command

2022-11-07T23:24:30+00:00

Sort this and put the command summary at the top instead of the bottom.

Adjust it so that the newlines are at the start of the strings, so that
there is not a blank line at the end.

test: Drop an unused parameter to ut_run_test_live_flat()

2022-11-07T23:24:30+00:00

The select_name parameter is not used anymore. Drop it.

dm: test: Clear the block cache after running a test

2022-11-07T23:24:30+00:00

Some tests access data in block devices and so cause the cache to fill
up. This results in memory being allocated.

Some tests check the malloc usage at the beginning and then again at the
end, to ensure there is no memory leak caused by the test. The block cache
makes this difficult, since the any test may cause entries to be allocated
or even freed, if the cache becomes full.

It is simpler to clear the block cache after each test. This ensures that
it will not introduce noise in tests which check malloc usage.

Add the logic to clear the cache, using the existing blkcache_invalidate()
function. Drop the duplicate code at the same time.

dm: test: Drop the special function for running DM tests

2022-11-07T23:24:30+00:00

This is not needed since the flag takes care of all differences. Make use
of the common function.

test: Correct pylint warnings in fs_helper

2022-11-07T23:24:30+00:00

Tidy this up so that pylint is happy. Use hex for the 1MB size and make
sure it is not a floating-point value.

Add a little main program to allow the code to be tried out, since at
present is only called from a long-running test.
