[PATCH v2 00/10] sunxi: Add support for A733 SoC

[Yixun Lan]

Allwinner A733 SoC[1] is an octa-core Cortex-A76/A55 processor, below
list the brief features. 

- Dual-core Cortex-A76, Hexa-core Cortex-A55, RISC-V E902 core
- UP to 16GB RAM, 192K+512K SRAM
- Imagination BXM-4-64 MC1 GPU
- Optional 3 TOPS NPU
- UFS3.0 storage
- eMMC, SD, SDIO
- Octal SPI
- HDMI, RGB, LVDS, eDP, MIPI display interface
- MIPI CSI, up 4 lanes
- Audio 5x I2S
- GMAC Ethernet
- USB3.1, 2.0 support
- PCIe 3.0 DM

Add support for Allwinner A733 SoC, target to support booting mainline
U-boot via FEL download mode, also add eMMC driver support, make it
able to load images from the eMMC/SD storage device.

I've not pushed DT part patches, but put a more complete working branch
at my development branch[2] for reference or testing if people
interested. Please note, we reply on vendor boot0 firmware for the DDR
initialization, then use sunxi-fel to down and execute U-Boot, see doc[3].
