[TF-M] Couple of adjustment patches coming

Hi,

For implementing coming features and optimization, there would be couples of adjustment patches coming, this is the first one (the number looks good): https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/8000

The idea is to get these patches to come in first so that we can have more time before the next release to fix spotted issues.

Please help to review the patches and provide different thinking if you have.

Thanks.
