I haven't looked in detail what would be needed for the SPL part of the
MMC driver to really work, I just checked that the base addresses are
correct, the pinmux looked alright as well.
The DT nodes are not needed for the SPL, and I don't see other changes
related to MMC in the original series?
Do you see UART output from the SPL, or nothing at all?
And you are not using UART0 on the PortF pins, so multiplexed with the
MMC, I guess?

Cheers,
Andre
