3a543a8084 arm: mach-k3: Add secure device support
K3 devices have High Security (HS) variants along with the non-HS already
supported. Like the previous generation devices (OMAP/Keystone2) K3
supports boot chain-of-trust by authenticating and optionally decrypting
images as they are unpacked from FIT images. Add support for this here.

ccdb7c2255 armv7r: K3: Allow SPL to run only on core 0
Based on the MCU R5 efuse settings, R5F cores in MCU domain
either work in split mode or in lock step mode.

If efuse settings are in lockstep mode: ROM release R5 cores
and SPL continues to run on the R5 core is lockstep mode.

If efuse settings are in split mode: ROM releases both the R5
cores simultaneously and allow SPL to run on both the cores.
In this case it is bootloader's responsibility to detect core
1 and park it. Else both the core will be running bootloader
independently which might result in an unexpected behaviour.

a3501a4a44 armv7R: K3: am654: Add support to start ATF from R5 SPL
Considering the boot time requirements, Cortex-A core
should be able to start immediately after SPL on R5.
Add support for the same.

Enable MPU regions for AM654 evm:
- Region0: 0x00000000 - 0xFFFFFFFF: Device memory, not executable
- Region1: 0x41c00000 - 0x42400000: Normal, executable, WB, Write alloc
- Region2: 0x80000000 - 0xFFFFFFFF: Normal, executable, WB, Write alloc
- region3-15: Disabled

With this dcache can be enabled either in SPL or U-Boot.
