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.
