I had similar issue on imx53 (hsc). The problem was with not properly
set GPIO pin by DM/DTS in SPL. The GPIO was responsible for eMMC card
detect, so the SPL code after checking this got the impression that the
card is missing -> hence the -19 error.

Interesting commit: SHA1: 7a0425dd969c44e6afb6936bf8205c8770e9dea9
