With the latest commit now the test-shell app mounts the SD card and there're new ls and vfs commands that work, tested with the Re-mote.

The SD card uses SPI. Above that there's the MTD layer, where MTD stands for Memory Technology Device, my understanding is that this is a hardware abstraction, idea borrowed from Linux as many other things in RIOT.

Then we've the filesystem, we use FAT but RIOT supports some more. And above the filesystem there is the VFS layer, where VFS stands for Virtual File System. Using VFS we should be able to switch to a different filesystem without changing user's code. Probably in the future we should use littlefs instead of fatfs (low priority though).

In our current stack we use the EEPROM to store configuration, but apparently the re-mote doesn't have EEPROM. So we will use the SD card instead.
