It is interesting that I do not see the problem if I don't use SPL. For example: on a mx6qsabresd I can boot the SanDisk card without issues if I boot the mx6qbsabresd_deconfig target (u-boot.imx binary). However, if I try booting the mx6sabresd_spl_defconfig (SPL + u-boot.img) the boot fails with the same error as I noticed on the mx6ul board. So it seems this is is SPL MMC related problem.
