Is there a chance to boot from SD-Card at all? Do you want to start barebox from USB/MMC or do you only want to load the kernel from USB/MMC? The latter is possible, though you have to add support for it. See arch/arm/boards/eukrea_cpuimx35/eukrea_cpuimx35.c for an example how to do it. Basically for MMC you have to configure the iomuxer and register the device. USB might be a bit more complicated, you have to configure the phy correctly.
