Merge patch series "Adding support to load secure firmware for HS devices"

Udit Kumar <[email protected]> says:

Some use case needs rproc firmware to be loaded at u-boot stage,
using following commands at u-boot shell, firmware could be loaded

=> setenv dorprocboot 1
=> run boot_rprocs

For Secure devices, secure version of rproc firmware should be loaded,
which is appended by sec keyword[0].
but currently non-secure firmware is loaded even for secure devices.
So adding support for loading secure firmware on Secured devices.
