In both cases I booted from FEL with rootfs on sdcard and tried to mount
partition from eMMC to /mnt. With your patch, last step it fails.

pre-patch working:
pll-ddr-other[768MHz] -> mmc2[512MHz]. (For some reason ahb-mmc2 is off?)

post-patch not working:
pll-periph[600MHz] ->  mmc2[500Mhz], (ahb-mmc2 is enabled)

Also, attached the logs.
