The Lichee Zero Plus is a core board made by Sipeed, with a microUSB
connector on it, TF slot or WSON8 SD chip, optional eMMC or SPI

It has a gold finger connector for expansion, and UART is available

reserved pins w/ 2.54mm pitch. The board can use either SoChip S3 or
Allwinner V3L SoCs.

Add the device tree binding of the basic version of the core board --
w/o eMMC or SPI Flash, w/ TF slot or WSON8 SD, and use S3 SoC.

If the S3 is just a rebranded V3, then we should have the v3 compatile
in that list too.

S3 is V3 with copackaged DDR3 DRAM.

It's pin incompatible w/ V3.

Does it matter though?

If the only thing that changes is the package, we're not manipulating
that, and any software that deals with the v3 can deal with the
s3. Which is what the compatible is about.

Okay. Should the S3 compatible be kept befoer the V3 one?
