4 Subject: [PATCH 34/93] mmc: fsl_esdhc: add workaround for non-removable card
7 The esdhc-2 usually uses some on-board memory devices such as eMMC
8 card or SDIO wifi module, and it doesn't support SDHC_CD_B. So we
9 could only assume it always has a card instead of detecting SDHC_CD_B
10 status. This patch is to add workaround for these non-removable
11 cards which are used by esdhc-2.
