I see no way to detect ATF version using smc_call().

Downstream Marvell ATF have the required code[1] in the 18.12.2
release[2], which is based on ATF 1.5. This is the last ATF version from
Marvell that was released on github.

Is there a way to detect if an older ATF is installed and print
an error message (warning) in this case?

Boot of Armada 8040 rev B0 hangs when U-Boot attempts to initialize the PCIe 
serdes. Adapt patches from downstream Marvell tree that move serdes 
initialization to ATF.

This series requires upstream ATF version 2.1 or newer.
