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.
