2 should be good to support non secure usecases. 5 not needed.

This value is incorrect, fix it to 133330000.

Do you see other corners in the reference catalog as well, not just the
downstream code ? OR did you limit this as the usecase do not demand higher corner ?

there was an internal AR50_LITE presentation where only these two
claimed to be supported - all of the others were not. so I went for the
most restrictive option (ie, this one).
how do you want me to proceed then? should I just use IPCAT, or downstream?

isnt it better to just leave 5 here - thinking of the future support for
secure buffers - and just update the dts?
