[PATCH v10 00/17] spacemit mmc driver

This series adds MMC support for the SpacemiT K1: an SDHCI platform
driver, the SD card device-tree overlay, defconfig options, and SPL
boot-device selection from the SoC strap/config registers. The SDHCI
driver is usable in both SPL and U-Boot proper.

A flashing guide (doc/board/spacemit/k1-flash.rst) describes how to
write images to eMMC.
