eMMC Boot mode: No plan exists to support eMMC boot mode (at present). This decision will likely be revisited in the future. Some (untested, preliminary) support exists for boot mode in the VerilogeMMC model. eMMC Collision Detection:Collision detection remains an ongoing issue with eMMC suppor...

In code I have noticed there is no piece of code for cd-gpios - card detection,wp-gpios for write protection and max burst width checking in dts function(sdhci_esdhc_imx_probe_dt in the file drivers/mmc/host/sdhci-esdhc-imx.c). These help me out to resol...

Here is a non RFC version of my patch-set to wait for card_busy before starting sdio requests. It is the same as the RFC version of the set, but this time it has been tested no hardware which actually needs this and I can confirm now that this fixes wifi on that hardware. ...
