0d92f2141a arm64: mvebu: Fix A8K memory mapping and add documentation
Fix the MMU mapping for A8K device family:
 - Separate A7K and A8K memory mappings
 - Fix memory regions by including IO mapping for all
   3 PCIe interfaces existing on each connected CP110 controller
Add A8K memory mapping documentation with all regions
configured by Marvell ATF.

b58385df3a arm64: mvebu: Add L3 cache flush functionality to A8K family
Add missing L3 cache flush functionality which absence prevents
Linux kernel from normal boot in case the L3 cache is enabled
by ATF.
The L3 cache is named the "last level" cache in order to keep
the terminology similar to the ATF code.
This cache should not be disabled by u-boot since the Linux
kernel cannot activate it, so it is activates at ATF stage.
However the cache flush is required for preventing data corruption
after disabling the MMU and the data cache before passing control
to the loaded Linux image.

6324fdc547 arm64: mvebu: Add regions for PCI spaces to the memory map
To use the PCIe driver, its controller memory and the PCIe regions need
to get mapped in the MMU. Otherwise these areas can't be accessed.

21b29fc64e arm64: mvebu: Add basic support for the Marvell Armada 7K/8K SoC
Compared to the Armada 3700, the Armada 7K and 8K are much more on the
high-end side: they use a dual Cortex-A72 or a quad Cortex-A72, as
opposed to the Cortex-A53 for the Armada 3700.

The Armada 7K and 8K also use a fairly unique architecture, internally
they are composed of several components:

- One AP (Application Processor), which contains the processor itself
  and a few core hardware blocks. The AP used in the Armada 7K and 8K
  is called AP806, and is available in two configurations:
  dual Cortex-A72 and quad Cortex-A72.
- One or two CP (Communication Processor), which contain most of the I/O
  interfaces (SATA, PCIe, Ethernet, etc.). The 7K family chips have one
  CP, while the 8K family chips integrate two CPs, providing two times
  the number of I/O interfaces available in the CP.
  The CP used in the 7K and 8K is called CP110.

All in all, this gives the following combinations:

- Armada 7020, which is a dual Cortex-A72 with one CP
- Armada 7040, which is a quad Cortex-A72 with one CP
- Armada 8020, which is a dual Cortex-A72 with two CPs
- Armada 8040, which is a quad Cortex-A72 with two CPs

This patch adds basic support for this ARMv8 based SoC into U-Boot.
Future patches will integrate other device drivers and board support,
starting with the Marvell DB-88F7040 development board.
