[RFC PATCH 00/38] arm64/sysreg: Convert aarch32 id regs

[James Morse <james.morse@arm.com>]

Hello!

To cleanup an erratum affecting aarch32, I wanted a mask for an id register.
This would have been quick to add, but the right thing to do is to convert
that register to automatic generation. If I was going that far, I may as
well do the lot...

I'll post this again at rc1, I've posted it now so folk can work on cleaning
up the cpufeature macro jungle! (leaving the maintainer off CC was
deliberate)

The patch that changes the size of the fields in the middle of the series
is the most interesting thing. I also discovered that the tools accept
'0b002' as a value.

This series is based on arm64/for-next/core, and can be retrieved from:
https://git.kernel.org/pub/scm/linux/kernel/git/morse/linux.git 'arm64/generated_sysreg/a32/rfc-v1

Thanks,
