Re: WARNING: Unimplemented Standard Service Call:

What system? From the message it sounds like the TF-A firmware isn't 
implementing a standard service call that should exist.

With some systems you can build the TF-A firmware yourself, but others 
it's provided as a binary you include as part of the UEFI build when 
producing a SPI-NOR image.
