A64 requires new clock mode on SD and eMMC controllers. Not using new clock mode causes stability issues of the driver - SPL may occasionally fail to load u-boot from SD for some particular SD card on some particular devices.
This series depends on "sunxi: add support for automatic delay calibration" from my Pinebook series.
