Reasons:
- USE_OLD_BDS requires duplicating updates between OVMF's library
instances that depend on USE_OLD_BDS being FALSE vs. TRUE. Examples:
d5aee61bfa OvmfPkg/QemuNewBootOrderLib: adapt Q35 SATA PMPN to UEFI
spec Mantis 1353
1da7616649 OvmfPkg/QemuBootOrderLib: adapt Q35 SATA PMPN to UEFI spec
Mantis 1353
- The Xen community has embraced the new BDS. Examples:
14b2ebc30c OvmfPkg/PlatformBootManagerLib: Postpone the shell
registration
49effaf26e OvmfPkg/PciHostBridgeLib: Scan for root bridges when
running over Xen
- OVMF doesn't build with "-D USE_OLD_BDS -D HTTP_BOOT_ENABLE" anyway, as
NetworkPkg/HttpBootDxe now requires UefiBootManagerLib:
50a65824c7 NetworkPkg: Use UefiBootManagerLib API to create load
option.
We (correctly) don't resolve UefiBootManagerLib when USE_OLD_BDS is
TRUE.
- The new BDS has been working well; for example it's the only BDS
available in ArmVirtPkg:
1946faa710 ArmVirtPkg/ArmVirtQemu: use MdeModulePkg/BDS
