Since commit 54e4fcfa3c749a78 ("ARM: mx6: add MMC2 boot device detection support in SPL") we can no longer boot from SD card on a mx6sx Udoo neo board:
U-Boot SPL 2016.11-32108-g9cd37b0 (Nov 30 2016 - 11:05:54) Trying to boot from MMC2 MMC Device 1 not found spl: could not find mmc device. error: -19 SPL: failed to boot from all boot devices ### ERROR ### Please RESET the board ###
Prior to this commit we had the following logic:
/* SD/eSD: 8.5.3, Table 8-15 */ case 0x4: case 0x5: return BOOT_DEVICE_MMC1; /* MMC/eMMC: 8.5.3 */ case 0x6: case 0x7: return BOOT_DEVICE_MMC1;and in the case of MX6SX Udoo board we entered the case 0x5 (SD card boot) and returned BOOT_DEVICE_MMC1 as expected.
Now this does not happen anymore and BOOT_DEVICE_MMC2 is returned, which breaks the boot.
In order to fix this problem keep the original behavior for the SD card case by returning BOOT_DEVICE_MMC1.
Tested on mx6cuboxi and mx6sx UDOO neo boards.
