Great, that script does work. It is lacking usage output, but looking at
the code, its arguments were self-documenting.

I tried R28.1 flash.sh -k TOS with my ATF v1.4 with Spectre backports,
without SPD. BL31 appears to initialize okay, but later something runs
into an unhandled SMC 0x82000015 - things then go south and it doesn't
reach the Nvidia U-Boot. Serial log attached.

According to
https://github.com/ARM-software/arm-trusted-firmware/blob/master/docs/arm-sip-service.rst
that SMC function ID falls into the SiP range, so indeed something
Nvidia-specific missing in v1.4?

Regards,
Andreas
