RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429 IntelTdx.h defines the defition used by TDX in OvmfPkg: - Mailbox related defitions,such as the data structure, command code, AP relocation defitions. See Table 5.44 Multiprocessor Wakeup Mailbox Structure in below link. https://uefi.org/specs/ACPI/6.4/05_ACPI_Software_Programming_Model/ ACPI_Software_Programming_Model.html#multiprocessor-wakeup-structure Cc: Ard Biesheuvel <ardb+tianocore@kernel.org> Cc: Jordan Justen <jordan.l.justen@intel.com> Cc: Brijesh Singh <brijesh.singh@amd.com> Cc: Erdem Aktas <erdemaktas@google.com> Cc: James Bottomley <jejb@linux.ibm.com> Cc: Jiewen Yao <jiewen.yao@intel.com> Cc: Tom Lendacky <thomas.lendacky@amd.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Acked-by: Gerd Hoffmann <kraxel@redhat.com> Reviewed-by: Jiewen Yao <jiewen.yao@intel.com> Signed-off-by: Min Xu <min.m.xu@intel.com>
