9a04b9a439 test/py: Allow tests to be filtered by role
Some test can only be run by a particular board in a lab, e.g. because
they are loaded with an OS image used by the test. Add a way to specify
this in tests.

It is sometimes tricky to figure out what modules test.py is loading

what when wrong.

752c376987 test/py: Shorten u_boot_console
This fixture name is quite long and results in lots of verbose code.
We know this is U-Boot so the 'u_boot_' part is not necessary.

But it is also a bit of a misnomer, since it provides access to all the
information available to tests. It is not just the console.

It would be too confusing to use con as it would be confused with
config and it is probably too short.

So shorten it to 'ubman'.

ba87a2fcfb test/py: Provide the correct U_BOOT_SOURCE_DIR to getrole
The u-boot-test-getrole script runs before the normal environment
variables have been set up. This is unavoidable since the script is
providing necessary information to test.py

This means that U_BOOT_SOURCE_DIR is not set in the environment.

As a result, Labgrid uses its default source path, configured in its
environment variable. While this may happen to work, it is not correct.
Also, it causes problems when running from Gitlab, where the runner may
not have access to that source path.

Provide the required source path in U_BOOT_SOURCE_DIR so that Labgrid
does the right thing.

a8f09d6282 test/py: Always use the current dir as the source tree
The logic in get_details() retrieves the default source directory from
the Labgrid settings. This is convenient for interactive use, since it
allows pytests to be run from any directory and still find the source
tree.

However, it is not actually correct.

Gitlab sets the current directory to the source tree and expects that to
be used. At present it is ignored. The result is that Gitlab builds
whatever happens to be in the default source directory, ignoring the
tree it is supposed to be building.

Fix this by using the directory of the source tree, always. This is
obtained by looking at the grandparent of the conftest.py file.

8f2a9fa7d6 test: Support testing with two board-builds
The Beagleplay board uses an SoC from the TI K3 family. This has both a
Cortex-R core and a Cortex-A core and the R core needs to come up before
the A core. In both cases we have U-Boot SPL then U-Boot proper being
used.

In practice this means we need two entirely separate builds to produce
an image.

Handle this in test.py by adding more parameters.

bf89a8f1fc test: Introduce the concept of a role
In Labgrid there is the concept of a 'role', which is similar to the
U-Boot board ID in U-Boot's pytest subsystem.

The role indicates both the target and information about the U-Boot
build to use. It can also provide any amount of other configuration.
The information is obtained using the 'labgrid-client query' operation.

Using this role, all required configuration for the board is stored
within the Labgrid environment, with pytest simply querying it. This
allows connecting to boards using an interactive console, something that
isn't possible without some kind of mapping. It also means that we don't
need to replicate the pytest functionality in tbot, since Labgrid can
handle the console and kick off builds as needed.

Make use of this in tests, so that only the role is required in gitlab
and other situations. The board type and other things can be queried
as needed.

Use a new 'u-boot-test-getrole' script to obtain the requested
information.

With this it is possible to run lab tests in gitlab with just a single
'ROLE' variable for each board.

Note that, without this feature:
- interactive use of boards with Labgrid-sjg would require repeating the
  id/board in a separate configuration file
- Gitlab yaml file would need to specify both the id and board

This feature is entirely optional, however, with the code gracefully
falling back to using a separate ID and board.

6f3583074f test: Allow connecting to a running board
Sometimes we know that the board is already running the right software,
so provide an option to allow running of tests directly, without first
resetting the board.

This saves time when re-running a test where only the Python code is
changing.

Note that this feature is open to errors, since the user must know that
the board is in a fit state to execute tests. It is useful for repeated
iteration on a particular test, where it can save quite a bit of time.

cbd71fad6d test: Support tests which can only be run manually
At present we normally write tests either in Python or in C. But most
Python tests end up doing a lot of checks which would be better done in C.
Checks done in C are orders of magnitude faster and it is possible to get
full access to U-Boot's internal workings, rather than just relying on
the command line.

The model is to have a Python test set up some things and then use C code
(in a unit test) to check that they were done correctly. But we don't want
those checks to happen as part of normal test running, since each C unit
tests is dependent on the associate Python tests, so cannot run without
it.

To acheive this, add a new UT_TESTF_MANUAL flag to use with the C 'check'
tests, so that they can be skipped by default when the 'ut' command is
used. Require that tests have a name ending with '_norun', so that pytest
knows to skip them.

689d0a1cb0 test/py: Relax the naming rules for unit tests
At present the collection function used by pytest is quite strict on the
naming of the functions it detects. In particular it requires the name of
the test to be repeated in the function name.

This is not enforced anywhere else, but instead the tests are silently
omitted from the pytest run. This affects a few dozen tests.

The rule does not seem to have any particular purpose. Relax it, so that
all tests that use the UNIT_TEST() macro will run, regardless of the name
of the test function.

6f243e25e6 test/py: improve regular expression for ut subtest symbol matcher
Improve the regular expression that matches unittest symbols in
u-boot.sym.

Currently we do not enforce no prefix in symbol string, but with the
soon to come change in linker lists declaring lists and entries with the
__ADDRESSABLE macro (because of LTO), the symbol file will contain for
every symbol of the form
  _u_boot_list_2_ut_X_2_Y
also symbol
  __UNIQUE_ID___addressable__u_boot_list_2_ut_X_2_YN,
(where N at the end is some number).

In order to avoid matching these additional symbols, ensure that the
character before "_u_boot_list_2_ut" is not a symbol name character.

372497572b test/py: fix runtest wrapper for pytest 6
The implementation of pytest_runtest_protocol() must call
pytest_runtest_logstart() and pytest_runtest_logfinish(). This appears to
be necessary even in pytest 5.2.1 judging by the default version of
pytest_runtest_protocol(), but evidently some form of code reorganization
in pytest only made this have a practical effect in the newer version. I'd
previously been under the impression that 100% of the required work of
pytest_runtest_protocol() was handled by the fact it called
runtestprotocol() as its implementation. However, it appears that custom
implementations do need to do a little more than this.

f5ec7eebf7 test/py: Allow using buildman to build U-Boot
It is a pain to have to set the CROSS_COMPILE environment variable when
using test.py's --build option. It is possible to get this using the -A
option from buildman. But it seems better to just use buildman to do the
build when it is available.

However using buildman adds a new dependency to the test system which we
want to avoid. So leave the default as is and add a flag to make it use
buildman.

Note that most of these changes relate to test.py and the parts of the
travis/gitlab/azure scripts which relate to running test and building a
suitable U-Boot to run the tests on.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

features into sandbox. So this commit may not be necessary.

0671960bee test/py: Allow tests to control the sandbox device-tree file
Normally tests will run with the test.dtb file designed for this purpose.
However, the verified boot tests need to run with their own device-tree
file, containing a public key.

Make the device-tree file a config option so that it can be adjusted by
tests. The default is to keep the current behaviour.

1326022c2e test/py: print summary in test order
Use lists rather than sets to record the status of tests. This causes
the test summary in the HTML file to be generated in the same order as
the tests are (or would have been) run. This makes it easier to locate
the first failed test. The log for this test might have interesting
first clues re: interaction with the environment (e.g. hardware flashing,
serial console, ...) and may help tracking down external issues.

06088b0473 test/py: don't import pexpect
The code replaced pexpect with custom code long ago. Don't import the
unused module so it doesn't need to be installed.

1cd85f571d test/py: run all "ut" subtests
Invoke each "ut"-based unit test as a separate pytest.

Now that the DM unit test runs under test/py, remove the manual shell

83357fd5c2 test/py: HTML awesome!
Implement three improvements to the HTML log file:
- Ability to expand/contract sections. All passing sections are contracted
  at file load time so the user can concentrate on issues requiring
  action.
- The overall status report is copied to the top of the log for easy
  access.
- Add links from the status report to the test logs, for easy navigation.

This all relies on Javascript and the jquery library. If the user doesn't
have Javascript enabled, or jquery can't be downloaded, the log should
look and behave identically to how it did before this patch.

A few notes on the diff:

- A few more 'with log.section("xxx")' were added, so that all stream
  blocks are kept within a section block for consistent HTML entity
  nesting structure. This changed indentation in a few places, making
  the diff look slightly larger.
- HTML entity IDs are cleaned up. We assign simple incrementing integer
  IDs now, rather than using mangled test names which were possibly
  invalid.
- Sections and streams now use common CSS class names (in addition to the
  current separate class names) to more easily share the new behaviour.
  This also reduces the CSS file size since rules don't need to be
  duplicated.
- An "OK" status is logged after some external command executions so that
  make and flash steps are auto-contracted at log file load time, assuming
  they passed.

89ab841088 test/py: support running sandbox under gdbserver
Implement command--line option --gdbserver COMM, which does two things:

a) Run the sandbox process under gdbserver, using COMM as gdbserver's
   communication channel.

b) Disables all timeouts, so that if U-Boot is halted under the debugger,
   tests don't fail. If the user gives up in the middle of a debugging
   session, they can simply CTRL-C the test script to abort it.

This allows easy debugging of test failures without having to manually
re-create the failure conditions. Usage is:

Window 1:
./test/py/test.py --bd sandbox --gdbserver localhost:1234

Window 2:
gdb ./build-sandbox/u-boot -ex 'target remote localhost:1234'

When using this option, it likely makes sense to use pytest's -k option
to limit the set of tests that are executed.

Simply running U-Boot directly under gdb (rather than gdbserver) was
also considered. However, this was rejected because:

a) gdb's output would then be processed by the test script, and likely
   confuse it causing false failures.

b) pytest by default hides stdout from tests, which would prevent the
   user from interacting with gdb.

   While gdb can be told to redirect the debugee's stdio to a separate
   PTY, this would appear to leave gdb's stdio directed at the test
   scripts and the debugee's stdio directed elsewhere, which is the
   opposite of the desired effect. Perhaps some complicated PTY muxing
   and process hierarchy could invert this. However, the current scheme
   is simple to implement and use, so it doesn't seem worth complicating
   matters.

c) Using gdbserver allows arbitrary debuggers to be used, even those with
   a GUI. If the test scripts invoked the debugger themselves, they'd have
   to know how to execute arbitary applications. While the user could hide
   this all in a wrapper script, this feels like extra complication.

An interesting future idea might be a --gdb-screen option, which could
spawn both U-Boot and gdb separately, and spawn the screen into a newly
created window under screen. Similar options could be envisaged for
creating a new xterm/... too.

--gdbserver  currently only supports sandbox, and not real hardware.
That's primarily because the test hooks are responsible for all aspects of
hardware control, so there's nothing for the test scripts themselves can
do to enable gdbserver on real hardware. We might consider introducing a
separate --disable-timeouts option to support use of debuggers on real
hardware, and having --gdbserver imply that option.
