[U-Boot] what are valid formats for initrd image downloaded and used by "bootm"

[Robert P. J. Day]

  using yocto project to build artifacts to tftp down to a board for
"bootm" command -- what are the valid formats for the "initrd" object
that can be recognized by "bootm"? since YP can generate a *ton* of
different image types. thanks.
