[U-Boot] [PATCH v3 4/6] cmd: Remove mmc_spi command

Mon Jul 8 04:10:55 UTC 2019


The mmc_spi command was added to manually setup MMC over SPI bus
using command. This was required by the legacy non-DM MMC_SPI driver.

With DM based MMC_SPI driver in-place, we can now use all general
storge commands and mmc command for MMC over SPI bus hence we remove
the mmc_spi command all it's references.
