Are you sure? There probably aren't any boards out there
without TF-A, but why shouldn't it work without it?

PSCI, i.e. the only means to start the secondary CPUs, is implemented
in TF-A, so it's very unlikely that anyone would want to run a system
without TF-A. Also quite a bit of the lowlevel SoC initialization is
implemented in TF-A.

Doesn't mean u-boot cannot implement PSCI; actually you doesn't need
it at all, you can still use spin tables. I just keep hearing the same
arguments for the LS1028A SoC and yet there is one board without TF-A ;)
Anyway, I admit it's rather unlikely.
