The Allwinner Tech Optimus Board by Merrii is the evaluation board for the Allwinner A80 SoC with big.LITTLE Cortex-A15/-A7 configuration (32-bit ARMv7).

The sources leaked from Allwinner contain GPL violations in U-Boot and Linux kernel and therefore won't easily build with openSUSE's armhf gcc (binaries seem to be softfp).

Initial mainline kernel support is being prepared for v3.19. I succeeded in booting via USB-loaded binary downstream U-Boot, but neither SD nor USB nor Ethernet were enabled yet, so no rootfs.

I have prepared a draft patch for adding MMC/SD nodes to the device tree a week before Hackweek Interstellar, which likely depends on forward-porting pinctrl drivers first.

Upstream U-Boot would be another area that A80 support could be contributed to, for native device tree support.

Looking for mad skills in:

    As a workaround transferring a full rootfs as initramfs (suggestion algraf) had failed with libusb errors from the fel tool.

    Upstream work by others enabled USB, allowing me to successfully boot into an openSUSE armv7hl rootfs on a USB hard drive. SD is still not working.
