Fabio,

No, that commit is 'not' in v2021.07. Please test with master and you
should see that go away.

Regardless, Marek's suggestion is the right fix if you can manage
that... we really don't want to limit 4GB boards to 3GB. I was hoping
NXP would step up and address the peripheral drivers for this.
