[PATCH v3 04/11] arm: mach-k3: Add config option for packaging HSM firmware

[Beleswar Padhi]

Some K3 SoCs like J721S2, and J784S4 have a HSM (High Security Module)
M4F core in the Wakeup Voltage Domain which could be used to run secure
services like Authentication. Add a config option which indicates that
the SoC has a HSM core and the firmware for the core is available.
