This DXE driver will load/save persistent values for OVMF's config knobs,
plus expose those knobs via HII.
Contributed-under: TianoCore Contribution Agreement 1.0
Signed-off-by: Laszlo Ersek <ler...@redhat.com>
---
Notes:
- introduce driver emptily as first step, so that we can later add HII vs.
config (de)serialization in separate patches
- rename files: "PlatformConfig" -> "Platform"
