bool "Unit tests"
Select this to compile in unit tests for various parts of
U-Boot. Test suites will be subcommands of the "ut" command.
This does not require sandbox to be included, but it is most
often used there.
bool "Unit tests for time functions"
depends on UNIT_TEST
Enables the 'ut time' command which tests that the time functions
work correctly. The test is fairly simple and will not catch all
problems. But if you are having problems with udelay() and the like,
this is a good place to start.
