Reported by kernelci, It seems like some of these patches are causing
the exynos5250-arndale to fail to boot.
I looked briefly at the logs and the bisect report (which isn't
complete) and it turns out that the eMMC card at mmc0 isn't detected
properly.

Here's the boot summary (it turns out there are more boards failing,
don't know if all are related to dw_mmc, yet):
https://kernelci.org/boot/all/job/ulfh/kernel/v4.7-rc5-92-g4e01b578ade9/

Here's the bootlog:
https://storage.kernelci.org/ulfh/v4.7-rc5-92-g4e01b578ade9/arm-multi_v7_defconfig+CONFIG_EFI=y/lab-baylibre-seattle/boot-exynos5250-arndale.txt

Please, could any of you dw_mmc experts have a look at this as soon as
possible!?

Kind regards
Uffe
