bootstd test suit is not working on master with the sandbox_defconfig:
https://termbin.com/un0p

Noticeable things are;
test/boot/bootdev.c:160, bootdev_test_any(): 0 == bootdev_find_by_any(seq, &dev, &mflags): Expected 0x0 (0), got 0xffffffed (-19)
Test: bootdev_test_any: bootdev.c (flat tree)
test/boot/bootdev.c:160, bootdev_test_any(): 0 == bootdev_find_by_any(seq, &dev, &mflags): Expected 0x0 (0), got 0xffffffed (-19)
Test 'bootdev_test_any' failed 2 times

And a nice segfault:
Test: bootflow_set_arg: bootflow.c
Test: bootflow_system: bootflow.c
[3]    569337 segmentation fault (core dumped)  ./u-boot

Maybe things are missing to run sandbox_defconfig on my computer?
With the sandbox64_defconfig there is not core dump anymore but there is still
the failed line:
Test 'bootdev_test_bootable' failed 2 times

And the uboot is reboot infinitely during the bootflow test:
./u-boot -T -c "ut bootstd"
