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
Don't know whether this is SPL size issue or not? can you try SPL_OF_PLATDATA and TINY* I can see the size reduced with 64512 bytes (one build issue on fdtdec_get_int undefined)
