ArmPkg: Add FF-A related dynamic Pcd and Guid
To communicate with spmc or spmd, UEFI needs to map the Rx/Tx buffer
(which is a global resource in a partition)
by getting the required information from the partition descriptor.
for this, Define ArmFfaLib related Pcd and Guid.
Pcd:
- PcdFfaLibConduitSmc
conudit to use ArmFfaLib.
- PcdFfaTxBufeer
address of Tx buffer.
- PcdFfaRxBuffer:
address of Rx buffer.
- PcdTxRxPageCount:
specify buffer size with EFI_PAGE_SIZE unit.
- PcdFfaExitBootEventRegistered:
check exit boot event registered to unmap rx/tx buffer.
Guid:
- gArmFfaRxTxBufferInfoGuid:
This is used in Hob to get Rx/Tx buffer information to pass
Rx/Tx buffer information via HobList if Rx/Tx Buffer mapped in
PEI phase.
