Subject: OvmfPkg/PlatformPei: remove Xen support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The "OvmfPkg/PlatformPei/PlatformPei.inf" module is used by the following
platform DSCs:

  OvmfPkg/AmdSev/AmdSevX64.dsc
  OvmfPkg/OvmfPkgIa32.dsc
  OvmfPkg/OvmfPkgIa32X64.dsc
  OvmfPkg/OvmfPkgX64.dsc

Remove Xen support from "OvmfPkg/PlatformPei", including any dependencies
that now become unused. The basic idea is to substitute FALSE for "mXen".

Remove "OvmfPkg/PlatformPei" from the "OvmfPkg: Xen-related modules"
section of "Maintainers.txt".

This patch is best reviewed with "git show -b -W".
