Some pytest modules exercising the dispatch added by
fs: dispatch null_dev_desc_ok filesystems before lookup
test_load_semihosting.py:
"load semihosting - <addr> <file>" and the optional
[bytes] [pos] variant. Runs on qemu_arm64 with
CONFIG_SEMIHOSTING=y; reuses test_hostfs.py's host-staged
fixture.
test_load_sandbox.py:
"load sandbox - <addr> <file>" and the optional [bytes] [pos]
variant. Runs on sandbox (boardspec('sandbox')); the sandbox
fstype is registered with name="sandbox" and
null_dev_desc_ok=true,
so the same fs_lookup_null_dev_info() helper that
routes semihosting also routes the "sandbox".
A "load ubifs - <addr> <file>" test is intentionally not provided.
UBIFS is built on UBI on MTD, which requires some additional works
that are not available with qemu/sandbox-ing.
