When a FIT includes some OS requests, U-Boot should process these and add the requested info to corresponding subnodes of the /chosen node. Add a pytest for this, which sets up the FIT, runs bootm and then uses a C unit test to check that everything looks OK. The test needs to run on sandbox_flattree since we don't support device tree fixups on sandbox (live tree) yet. So enable BOOTMETH_VBE and disable bootflow_system(), since EFI is not supported on sandbox_flattree. Add a link to the initial documentation. Signed-off-by: Simon Glass <sjg@chromium.org>
