Yes, Udoo Neo boots from the SDHC2 port.
However BOOT_DEVICE_MMC1 does not mean "boot from the SDHC1 port".
BOOT_DEVICE_MMC1 just tells SPL to boot from the first registered mmc device.
Please take a look at common/spl/spl_mmc.c
int spl_mmc_get_device_index(u32 boot_device)
{
switch (boot_device) {
case BOOT_DEVICE_MMC1:
return 0;
case BOOT_DEVICE_MMC2:
case BOOT_DEVICE_MMC2_2:
return 1;
}
,so we should return BOOT_DEVICE_MMC1 as we always did.
mx6cuboxi is also broken for the same reason.
If you took the assumption that in "BOOT_DEVICE_MMC1 = Boot from SDHC1
port" in 54e4fcfa3c749a78 ("ARM: mx6: add MMC2 boot device detection
support in SPL") I suggest we need to revert it.
