How is this going to be handled? Will you apply your patch
upstream and update the meta-fsl-arm recipe, or just add the
patch there?
I still need to test it on warpboard. Will do it later later today as
I don't have access to it here at the moment. After I confirm it also
works there, then we can ask Otavio to apply it in linux-fslc.
Please discard my previous workaround patch.
Otavio found a commit from 4.1-rc1 that makes this problem go away:

mmc: sdhci: fix card presence logic in sdhci_request function
The sdhci_request function should consider a non-removable device
always present.
Call the correct logic already available in sdhci_do_get_cd function.
This fixes some logic paths where MMC requests are being made to
non-removable devices that do not have the card detect pin connected
on the hardware as it is non-removable.

Will also ask in the linux-mmc if this should be applied to stable.
Applying it on top of 4.0 linux-fslc makes the SD card detection
problem go away.
Thanks Otavio!
Regards,
Fabio Estevam
Sorry for the delay, it looks I somehow got several of Fabio's mails
with delay.
The patch works OK, tested on riotboard, on both USDHC2 & USDHC3
interfaces. Thanks a lot for your help, and also thanks to Gary for
reporting the issue.
Have a nice day,
Nikolay
