"""Execute a "ut" subtest.
The subtests are collected in function generate_ut_subtest() from linker
generated lists by applying a regular expression to the lines of file
spl/u-boot-spl.sym. The list entries are created using the C macro
UNIT_TEST().
Strict naming conventions have to be followed to match the regular
expression. Use UNIT_TEST(foo_test_bar, _flags, foo_test) for a test bar in
test suite foo that can be executed via command 'ut foo bar' and is
implemented in C function foo_test_bar().
Args:
u_boot_console (ConsoleBase): U-Boot console
ut_subtest (str): SPL test to be executed (e.g. 'dm platdata_phandle')

# happen since SPL tests are run in their own invocation of test.py, but
