[PATCH v1] mmc: core: Verify SD bus width

2019-04-15 Thread Raul E Rangel

The SD Physical Layer Spec says the following: Since the SD Memory Card shall support at least the two bus modes 1-bit or 4-bit width, then any SD Card shall set at least bits 0 and 2 (SD_BUS_WIDTH="0101"). This change verifies the card has specified a bus width. verified it didn't mount.
