arm64/sme: Fix tests for 0b1111 value ID registers

2022-06-08T17:38:00Z

For both ID_AA64SMFR0_EL1.I16I64 and ID_AA64SMFR0_EL1.I8I32 we check for the presence of the feature by looking for a specific ID value of 0x4 but should instead be checking for the value 0xf defined by the architecture. This had no practical effect since we are looking for values >= our define and the only valid values in the architecture are 0b0000 and 0b1111 so we would detect things appropriately with the architecture as it stands even with the incorrect defines.

arm64/sysreg: Generate definitions for FAR_ELx

2022-05-20T17:49:58Z

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. Signed-off-by: Mark Brown Reviewed-by: Mark Rutland Link: https://lore.kernel.org/r/20220520161639.324236-7-broonie@kernel.org Signed-off-by: Catalin Marinas

arm64/sysreg: Generate definitions for CPACR_ELx

2022-05-20T17:49:29Z

Convert the CPACR system register definitions to be automatically generated using the definitions in DDI0487H.a. The kernel does have some additional definitions for subfields of SMEN, FPEN and ZEN which are not identified as distinct subfields in the architecture so the definitions are not updated as part of this patch.
