doc: Rename k210 partitions anchor

2021-02-26T14:30:55Z

This anchor is only for the k210 partition layout, so rename it appropriately. This keeps it from conflicting with the (to be added) anchor for U-Boot partitions in general. Signed-off-by: Sean Anderson Reviewed-by: Simon Glass

riscv: Add support for SPI on Kendryte K210

2021-01-18T03:06:26Z

This enables configs necessary for using SPI. The environment is saved to the very end of SPI flash. This is unlikely to be overwritten unless the entire flash is reprogrammed. This also supplies a default bootcommand. It loads an image and device tree from the first partition of the MMC. This is a minimal/least effort bootcmd, so suggestions (especially in the form of patches) are welcome. I didn't set up distro boot because I think it is unlikely that any general-purpose linux distros will ever be ported to this board.
