Fix up some missing unit tests with pytest
At present an Exception is raised if a command fails. This is a very broad
class and makes it difficult for callers to catch the error without also
catching other things, like programming bugs.
Change it to ValueError to make this easier.

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.

In some cases it is useful to search just by a partial name, such as
when looking for a sibling device that has a common name substring. Add
helper functions to handle these requirements.
Signed-off-by: Simon Glass <sjg@chromium.org>
At present we support reading a string list a string at a time. Apart
from being inefficient, this makes it impossible to separate reading of
the devicetree into the of_to_plat() method where it belongs, since any
code which needs access to the string must read it from the devicetree.
Add a function which returns the string property as an array of pointers
to the strings, which is easily used by clients.

If we look at the path that bootm/booti take when preparing to boot the
OS, we see that as part of (or prior to calling do_bootm_states,
explicitly) the process, bootm_disable_interrupts() is called prior to
announce_and_cleanup() which is where udc_disconnect() /
board_quiesce_devices() / dm_remove_devices_flags() are called from. In
the EFI path, these are called afterwards. In efi_exit_boot_services()
however we have been calling bootm_disable_interrupts() after the above
functions, as part of ensuring that we disable interrupts as required
by the spec. However, bootm_disable_interrupts() is also where we go
and call usb_stop(). While this has been fine before, on the TI J721E
platform this leads us to an exception. This exception seems likely to
be the case that we're trying to stop devices that we have already
disabled clocks for. The most direct way to handle this particular
problem is to make EFI behave like the do_bootm_states() process and
ensure we call bootm_disable_interrupts() prior to ending up in
usb_stop().

This change implements an SCMI transport for agent interfacing the
OP-TEE SCMI service. OP-TEE provides an SCMI PTA (Pseudo-TA) for
non-secure world to send SCMI messages over an identified channel.
The driver implemented here uses a SMT shared memory for passing
messages between client and server.
The implementation opens and releases channel resources for each
passed SCMI message so that resources allocated (sessions) or
registered (shared memory areas) in OP-TEE firmware are released for
example before relocation as the driver will likely allocate/register
them back when probed after relocation.
The integration of the driver using dedicated config switch
CONFIG_SCMI_AGENT_OPTEE is designed on the model posted to the
U-Boot ML by Patrick Delaunay [1].
