A custom board?
Is this using one of the platforms from edk2-platforms, or something
from Marvell's repositories?

Well, this bit is USB related, so we can probably ignore it.

Does your platform build configuration enable the eMMC?
The easiest explanation would be if your EDK2 simply does not support
the eMMC. As long as the hardware description tells Linux about it,
the kernel can access it even when the firmware does not know how to
use it.
