Sorry I'm not 100% sure what you are asking?
In EFI devices are named by Device Path, and a Device Path is a protocol that
lives on a Handle. So if an EFI driver produces a RAM disk either via adding
BlockIo or Simple File System protocols to a handle then that driver should
also add a device path protocol to the handle. There is not concept of mounting
in EFI, only connecting devices. If you connect the device drivers will layer
on top. So if the RAM disk produced Block IO, then the FAT32 driver would layer
on top of it if the block device looks like it is formatted for a FAT file
system. When booting generally only the boot device is connected to increase
boot speed, however if you boot to the EFI shell a connect is done, and you can
connect and disconnect devices at will via shell commands.
