Subject: [PATCH 0/4] read-only UDF file system support

Hi,

I'm posting this series again after ~3 years that introduces UDF file system 
support in UEFI. Why? Because Laszlo (or Red Hat) seemed to be interested in 
such support.

I started working on this driver just as an excuse to learn UEFI development at 
that time. This work isn't based on any previous one and it's BSD licensed. I 
also *never* intended to replace it with the default FAT file system. On the 
contrary, I was looking to give people an opportunity to use file system 
features that current FAT file system lacks.

This series was never reviewed or fully tested. I basically used Linux and 
mkudffs[1] to test different UDF disks, as well as booting a Linux (EFI stub) 
rootfs from UDF file systems. Please, I'd really appreciate if some of one 
could help reviewing or testing it.

Note that UDF file system support was *only* added to OVMF platform and it's 
disabled by default through UDF_ENABLE build option. There's also a feature PCD 
flag that turns on or off parsing of UDF volumes during partition discovery in 
PartitionDxe driver.
