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

[Paulo Alcantara <pcacjr@zytor.com>]

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.
