[PATCH V3 04/16] arm64/cpufeature: Introduce ID_PFR2 CPU register

2020-05-02 Thread Anshuman Khandual
This adds basic building blocks required for ID_PFR2 CPU register which provides information about the AArch32 programmers model which must be interpreted along with ID_PFR0 and ID_PFR1 CPU registers. This is added per ARM DDI 0487F.a specification. Cc: Catalin Marinas Cc: Will Deacon Cc: Marc
