you may need at A72/SPL stage as well,
Other J7 boards already have this config enabled in the a72 stage.
and do you think , R5/SPL will need this too ?
Any of the K3 devices does not enables this in R5 SPL, though we do have
HS400 enabled in the R5 stage.
Adding the config should result in a little performance gain I think.
