Banana Pi M2 Zero is a board by Sinovoip with Allwinner H2+ SoC, 16-bit 512MiB DDR3 memory, a MicroSD slot, two MicroUSB ports (one OTG and one powering-only) and a miniHDMI port.
DTS file is from Linux kernel with removing some nodes that are not needed in u-boot or not merged into u-boot yet.

Don't forget to CC me on the sunxi-related patches.

Why not using straight the DT from linux here? There's a couple of things missing from this one (the pinctrl nodes, for example).

Did you run savedefconfig recently? That should be the default nowadays.

That doesn't match the DT.
