Ruiyu Ni db27e9f3d8 OvmfPkg/LegacyRegion: Support legacy region manipulation of Q35
Current implementation only supports legacy region of 440 chip.
When QEMU is launched in Q35 mode using CSM enabled OVMF image,
LegacyBios driver fails to start due to the legacy region
[0xC0000, 0xFFFFF] cannot be written.

v2:
 * just updates the comments.

v3:
 * uses PcdOvmfHostBridgePciDevId as Jordan suggested.

Laszlo Ersek a99b5e629b OvmfPkg: CsmSupportLib: depend on OvmfPkg.dec explicitly
SVN r16375 (git commit 72a11001, "OvmfPkg: CsmSupportLib: Set/use platform
specific legacy interrupt device") added the

  gUefiOvmfPkgTokenSpaceGuid.PcdOvmfHostBridgePciDevId

PCD to CsmSupportLib. Since that "namespace" GUID is declared in
OvmfPkg/OvmfPkg.dec, and we've not used anything from OvmfPkg/OvmfPkg.dec
in CsmSupportLib.inf thus far, this is a new [Packages] dependency and
must be named.
