[PATCH v5 3/7] arm64/sysreg/tools: Move TRFCR definitions to sysreg
From: James Clark
Date: Tue Feb 20 2024 - 05:11:48 EST
Add separate definitions for ELx and EL2 as TRFCR_EL1 doesn't have CX.
This also mirrors the previous definition so no code change is required.
Also add TRFCR_EL12 which will start to be used in a later commit.
Unfortunately, to avoid breaking the Perf build with duplicate
definition errors, the tools copy of the sysreg.h header needs to be
updated at the same time rather than the usual second commit. This is
because the generated version of sysreg
(arch/arm64/include/generated/asm/sysreg-defs.h), is currently shared
and tools/ does not have its own copy.
