[edk2-devel] [PATCH 1/5] ArmPkg/IndustryStandard: 32b/64b agnostic FF-A and Mm SVC IDs

[Etienne Carriere]

Defines ARM_SVC_ID_FFA_* and ARM_SVC_ID_SP_* identifiers for 32bit
function IDs as per SMCCC specification. Defines also generic ARM
SVC identifier macros to wrap 32bit or 64bit identifiers upon target
built architecture.
