nit: I would suggest also updating the documentation at the top of
this file (point 7) to clarify that new standardized tags must be
allocated in the firmware_handoff repo?
Also, to point out the obvious, there are a bunch of tags in the
standardized range in this file that don't match the firmware_handoff
spec. I guess you could add them since 0x100 is still free. However,
at least the BLOBLISTT_ACPI_TABLES tag would likely(?) be redundant
with the existing XFERLIST_ACPI_AGGR tag.

FWIW, according to my view of the tag allocation philosophy, I think
these kinds of tags should be allocated as official tags in the
standardized range (e.g. in a cluster of U-Boot-specific tags). I
would really recommend completely avoiding the non-standardized range
for anything other than local experimentation or tags internal to
closed-source code.
