Can you also confirm if mmc is working correctly on imx8mm evk?

I currently building with atf imx_4.19.35_1.1.0 and firmware-imx 8.5
(tried multiple versions, no difference) and I'm unable to get u-boot
to find the mmc device. The funny thing is that SPL itself seems to be
fine, the problem is really just u-boot:

Will investigate more tomorrow, but reporting as you might know where
the problem is.
