Add a defconfig for the Allwinner Nezha, a raspberrypi-style board built around the RISC-V 64bit D1 SoC. There is currently no upstream support, so use the git repos from Samuel Holland as explained on the linux-sunxi wiki: https://linux-sunxi.org/Allwinner_Nezha The U-Boot DTB is also used by opensbi, but the two branches are unfortunately not in sync at the moment, so add a patch to fix the compatible for the PLIC so opensbi makes it available to S-Mode (Linux). The use of the sun20i-d1-spl SPL bootloader / TOC1 file format also makes it a bit more complicated to build the boot image. As this is expected to only be a temporary issue, add a U-Boot patch to build the TOC1 image as part of the build rather than adding explicit support in our U-Boot package to do it.

Allwinner Nezha =============== Nezha is is a low-cost RISC-V 64-bit based platform, powered by an Allwinner D1 SoC. How to build ============ $ make nezha_defconfig $ make How to write the SD card ======================== Once the build process is finished you will have an image called "sdcard.img" in the output/images/ directory. Copy the bootable "sdcard.img" onto an SD card with "dd": $ sudo dd if=output/images/sdcard.img of=/dev/sdX Connect a TTL UART to the debug connector, insert the microSD card and plug in a USB-C cable to the PWR connector to boot the system.
