Subject: [edk2] [PATCH 0/3] MdeModulePkg/PciBus: Fix bug that doesn't produce BusOverride
It's a regression of below commit:
SHA-1: 8be37a5cee700777ca8e8e8a34cc2225b21931a7
* MdeModulePkg/SecurityStubDxe: Defer 3rd party image before EndOfDxe
When PciBus driver fails to load the Option ROM, it doesn't produce BusOverride protocol. It was a correct behavior before the above commit. But due to the above commit, BusOverride protocol never is produced by PciBus driver.
The patch fixes this issue using the following solution:
1. PciBus records the image device path when LoadImage fails.
2. Override.GetDriver() tries to look for the image handle using
the stored image device path.
