You could enable DEBUG in SPL, and disable SPL_SDP because of size will exceeds. Then see what happends.
Even without DEBUG enabled we get useful error messages:
U-Boot SPL 2019.07-rc2 (May 17 2019 - 09:30:33 -0300) Trying to boot from MMC1 spl: could not find mmc device 0. error: -19 SPL: failed to boot from all boot devices ### ERROR ### Please RESET the board ###
This means that err = uclass_get_device(UCLASS_MMC, mmc_dev, &dev); fails inside common/spl/spl_mmc.c
Why does this happen?
About the size difference:
Original defconfig generates an SPL of 76800 bytes With CONFIG_SPL_DM=y removed the SPL size goes to 68608 bytes.
I have no idea, then. My board is REV C4, chip 1.5
Mine is rev C2 with i.MX6Q rev1.2
