One additional topic to add is the dependency on bootloader update for
this as well. I know things are chicken or egg kind of problem, but
will be good to mention requires newer version than 2021.xx version of
u-boot as this is an "breaking" change. And, if we block both regions
off for bootloader compatibility, that is not feasible given the
limited SRAM available as well.
