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, mmake 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].
