Hi Everyone,

The recent commit d06d60d5 'mmc: sdhci-of-arasan: Issue DLL reset
explicitly' seems to break the eMMC on our zynqmp boards, we get
messages like this:
mmc0: error -110 whilst initialising MMC card
We're using the XCZU2EG-1SFVC784I parts [1]. I see that this is moving
the DLL reset out of ATF. So part of the issue might be that we're
using the 2019.1 ATF version.

thanks,
Paul

Can you please try any latest version if that fix your problem?

Manish: Please take look at this issue and try to replicate it.

Thanks,

Manish pointed me at the firmware patch here:
https://lore.kernel.org/patchwork/patch/1338926/

This fixed the issue for me. Thanks everyone.
