Fair enough.. I see that the base firmware name is in SoC.dtsi on a per
SoC basis. Agreed that exception can be an override if required
(unlikely in this case). Please document that rationale in the commit
message.
Since we just have a single HSM in each of the SoCs, am62p-hsm-m4f-fw
j722s-hsm-m4f-fw etc in SoC.dtsi would make sense.. just dont do a
generic hsm.bin kind of deal.
