Allows to compile OVMF without HashInstanceLibSha1, i.e. no SHA1 hash support in TPM/TCG modules. Signed-off-by: Gerd Hoffmann <kraxel@...> --- OvmfPkg/OvmfTpmComponentsDxe.dsc.inc | 2 ++

Rename TPM_ENABLE to TPM2_ENABLE and TPM_CONFIG_ENABLE to TPM2_CONFIG_ENABLE so they are in line with the ArmVirtPkg config option names. Add separate TPM1_ENABLE option for TPM 1.2

Split Tcg2ConfigPei.inf into two variants: Tcg2ConfigPeiCompat12.inf with TPM 1.2 backward compatibility included and Tcg2ConfigPei.inf supporting TPM 2.0 only. This allows x86 builds to choose

Allows to enable/disable TPM 1.2 support in OVMF. Allows to enable SHA-1 support for TPM hashing. Gerd Hoffmann (4): OvmfPkg: move tcg configuration to dsc and fdf include files OvmfPkg: create

With this in place the tpm configuration is not duplicated for each of our four ovmf config variants (ia32, ia32x64, x64, amdsev) and it is easier to keep them all in sync when updating the tpm

Some system may has multi PCI root bus. It needs to use PciRootBridgeIo protocol to get the root bus count. Scan each root bus to get all devices. REF:
