Hi Bryan,

Reusing the loadaddr to load the boot script breaks some of the logic we
want to have around the bootscript/FIT load addresses. Making a dedicated
bootscript address allows us to differentiate the bootscript load address
from the Linux Kernel or OPTEE load address, thus ensuring that no matter
what the load sequence the bootscript and Kernel/OPTEE binary load
addresses do not conflict.

Instead of implementing a new variable (bootscriptaddr), I think (IMHO)
it's time to migrate
to distroboot for the WaRP7 (like pico imx7 for instance).
In fact, in this specific case, this allows to use the common
scriptaddr[1] variable.
FYI, this is a task I am currently working on [2] (work in progress).
Maybe we could integrate this migration into this series ?
