From: Eric Auger <eric.au...@redhat.com>
Introduce a script that automates the generation of system register
properties definitions from a given linux source tree
arch/arm64/tools/sysreg.
Invocation of
./update-aarch64-sysreg-code.sh $PATH_TO_LINUX_SOURCE_TREE
in scripts directory additionally generates
target/arm/cpu-sysreg-properties.c containing definitions for
feature ID registers.
update-aarch64-sysreg-code.sh additionally calls
gen-cpu-sysreg-properties.awk which is inherited from kernel
arch/arm64/tools/gen-sysreg.awk. All credits to Mark Rutland
the original author of this script.
[CH: split off from original patch adding both sysreg definitions
and properties]
