I am missing here a way to pass additional parameters to TF-A (as in
TFA_ADDITIONAL_PARAMETERS in Alejandro's version) as there are many
other options (some of which may be vendor specific) that are not explicitly
defined in the .in file.

This should probably remove whatever was installed in targetinstall
(TF_A_ARTIFACTS)
instead of "bl1.bin" and "fip.bin".
