The SoPine is a SoM by Pine64, with an Allwinner A64 SoC, a LPDDR3 DRAM chip, an AXP803 PMIC, a SPI NOR Flash and a MicroSD slot. The card detect pin of the MicroSD slot is broken, however, it doesn't matter as the design of SoPine didn't allow hot-swapping the MicroSD card (The MicroSD slot is at the back of the SoM, and when the SoM is installed on the baseboard, it's nearly impossible to remove the MicroSD).
The official baseboard of it is a board with nearly the same connectors with the original Pine64+, with the MicroUSB power jack replaced, and at the position of MicroSD slot a eMMC module slot is added.
Add support for SoPine with the official baseboard by adding its defconfig file. It still uses the device tree of Pine64, however, it will change after a proper device tree of SoPine with baseboard is accepted by Linux mainline.
There is some point in this, but I wonder if we actually need to wait for Linux. In fact since the SoPine has SPI flash, we don't desperately need a DT in the Linux source tree, since it could just come with the device - as in U-Boot's DT passed through to the kernel.
So can we have a separate DT, probably including -pine64.dts and at least adding the eMMC? Could be copy&paste version of the BPi-M64, for instance.
In fact changing the defconfig is now enough to initialize the MMC2 controller.
See "CONFIG_MMC_SUNXI_SLOT_EXTRA=2" below.
One more below ....

Can you add the SPL SPI flash options here? This allows loading U-Boot from SPI flash and makes this much more useful.
Yes, seems useful...
Cheers, Andre.
