bootm command. This feature is available if U-Boot is configured with::

An external image file can be downloaded from TFTP, when related
details are provided by the boardenv_* file; see the comment at the
beginning of this file.
If the size of the TFTP file is not provided within env__efi_fit_tftp_file,
the test image is generated automatically and placed in the TFTP root
directory specified via the 'dn' field.
When running the tests on Sandbox, the image file is loaded directly
from the host filesystem.
Once the load address is available on U-Boot console, the 'bootm'
command is executed for either 'config-efi-fdt' or 'config-efi-nofdt'
FIT configuration, depending on the value of the 'enable_fdt' function
argument.
Eventually the 'Hello, world' message is expected in the U-Boot console.

enable_fdt: Flag to enable using the FDT blob inside FIT image.
enable_comp: Flag to enable GZIP compression on EFI and FDT
generated content.
