From: James Morse Date: Wed, 30 Nov 2022 17:16:08 +0000 (+0000) Subject: arm64/sysreg: Standardise naming for ID_PFR1_EL1 X-Git-Tag: Ubuntu-6.2.0-16.16~1414^2~2^2~30 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=0a648056d68d4049dfb5d1c36b79ad3eba0090f0;p=mirror_ubuntu-kernels.git arm64/sysreg: Standardise naming for ID_PFR1_EL1 To convert the 32bit id registers to use the sysreg generation, they must first have a regular pattern, to match the symbols the script generates. Ensure symbols for the ID_PFR1_EL1 register have an _EL1 suffix, and use lower case in feature names where the arm-arm does the same. No functional change.
