The AXP805 PMIC used with H6 is capable of shutting down the system. Add support for using it to shut down the system power. The original placeholder power off code is moved to A64 code, as it's still TODO to implement PMIC operations for A64. Signed-off-by:Icenowy Zheng <icenowy@aosc.io>

As the ATF may need to do some power initialization on Allwinner platform with AXP PMICs, call the PMIC setup code in BL31. Stub of PMIC setup code is added, to prevent undefined reference. Signed-off-by:

The relative VER_REG *offset* is the same across all known SoCs, so we can define this offset near it's user. Remove it from the memory map. Reported-by:

Some peripherals are TrustZone aware, so they need to be configured to be accessible from non-secure world, as we don't need any of them being exclusive to the secure world. This affects some clocks, DMA channels and the Secure Peripheral Controller (SPC). The latter controls access to most devices, but is not active unless booting with the secure boot fuse burnt.

sun50i_cpu_on will be used by the PSCI implementation to initialize secondary cores for SMP. Unfortunately, sun50i_cpu_off is not usable by PSCI directly, because it is not possible for a CPU to use this function to power itself down. Power cannot be shut off until the outputs are clamped, and MMIO does not work once the outputs are clamped. But at least CPU0 can shutdown the other cores early in the BL31 boot process and before shutting down the system. Signed-off-by:

The Allwinner A64 SoC is quite popular on single board computers. It comes with four Cortex-A53 cores in a singe cluster and the usual peripherals for set-top box/tablet SoC. The ATF platform target is called "sun50i_a64". [Andre: adapted to amended directory layout, removed unneeded definitions ] Signed-off-by:
