From a897269c932999a5c028654489ad68baa6806fdb Mon Sep 17 00:00:00 2001 From: Anup Patel Date: Mon, 8 Jul 2019 04:10:55 +0000 Subject: [PATCH] cmd: Remove mmc_spi command 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.
