From e3e641993a1a5148e71bdd3f7b3cb5da695b1632 Mon Sep 17 00:00:00 2001

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