[PATCH v1 9/9] arm64/sysreg: Generate definitions for FAR_ELx

Mark Brown broonie at kernel.org
Tue May 17 11:22:19 PDT 2022


Convert FAR_ELx to automatic register generation as per DDI0487H.a. In the
architecture these registers have a single field "named" as "Faulting
Virtual Address for synchronous exceptions taken to ELx" occupying the
entire register, in order to fit in with the requirement to describe the
contents of the register I have created a single field named ADDR.

No functional change.
