The ArmPkg has a driv= er 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 conten= ts on an FV (Firmware Volume): https://git= hub.com/tianocore/edk2/tree/master/MdeModulePkg/Universal/FvSimpleFileSyste= mDxe
FV is defined in the PI Spec as a layout for flash that = contains files, but no directories. 

Thanks,
