FYI you can have much larger files in the newer version of the filesystem. See

Hi, John
Can you show how do you add your FV?
[FV.MY_FV]
balabala
I cannot find a way to insert a linux.efi and initrd into FV. But I see you
success.
If you are willing, your work on this post will be very meaningful. Can you
write a blog with all the steps?
Thank you very much!

Maybe ref to ramdisk sample, create a memory type block io device, then mount
file system on it.
UEFI supports fat file system, some 3rd drivers could be added to support ext4
filesystem.

Hi Michael,
Thanks for the tool recommendation.
However, the tools are useful for x86, arm, and IPF platforms. I'm working on a
RISC-V platform.
I wanted to compile the tools for RISC-V, but the link is not found:

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
