OvmfPkg: Create initial version of PlatformInitLib
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3863
There are 3 variants of PlatformPei in OvmfPkg:
- OvmfPkg/PlatformPei
- OvmfPkg/XenPlatformPei
- OvmfPkg/Bhyve/PlatformPei/PlatformPei.inf
These PlatformPeis can share many common codes, such as
Cmos / Hob / Memory / Platform related functions. This commit
(and its following several patches) are to create a PlatformInitLib
which wraps the common code called in above PlatformPeis.
In this initial version of PlatformInitLib, below Cmos related functions
are introduced:
- PlatformCmosRead8
- PlatformCmosWrite8
- PlatformDebugDumpCmos
They correspond to the functions in OvmfPkg/PlatformPei:
- CmosRead8
- CmosWrite8
- DebugDumpCmos
Considering this PlatformInitLib will be used in SEC phase, global
variables and dynamic PCDs are avoided. We use PlatformInfoHob
to exchange information between functions.
EFI_HOB_PLATFORM_INFO is the data struct which contains the platform
information, such as HostBridgeDevId, BootMode, S3Supported,
SmmSmramRequire, etc.
After PlatformInitLib is created, OvmfPkg/PlatformPei is refactored
with this library.
