There are also utilities to partition and format.

MdeModulePkg/Universal/Disk/RamDiskDxe/RamDiskDxe.inf is a virtual storage device, so it just emulates an unformatted disk. You would need to partition or initialize the file system given you have a RAM disk.

The file system driver lives here: https://github.com/tianocore/edk2/tree/master/FatPkg/EnhancedFatDxe

The ArmPkg has a driver that lets you do a file system over JTAG: https://github.com/tianocore/edk2/blob/master/ArmPkg/Filesystem/SemihostFs/Arm/

You can make a ReadOnly file system out of contents on an FV (Firmware Volume): https://github.com/tianocore/edk2/tree/master/MdeModulePkg/Universal/FvSimpleFileSystemDxe
FV is defined in the PI Spec as a layout for flash that contains files, but no directories.

Thanks,

Andrew Fish
