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.
