Overall architecture is very similar to SCPI[4] as follows:

Dumb Q: I'm curious about the limitations in SCPI that were found that
made TI decided to implement its own version.

Long story short, investigation was done into what SCPI was providing
(TI internal ofcourse) and SCPI did not fit our SoC generation needs -

Thanks for the detailed explanation.  Very helpful.

To be clear, I'm not a proponent of always using ARM "standards"
(especially when it's not exactly clear if it's a standard or a Juno
thing) but I'm seeing several SoCs come out with SCPI derivatives, or
old ARM versions etc., so was just curious about the decision making
process.

Thanks for sharing,

Kevin

So, any other comments for this series or shall we still try to get it merged for 4.9? We are -rc5 so it might be too late already and probably better to push this for 4.10.
