Date: Wed, 30 Nov 2022 17:15:59 +0000	[thread overview]
Message-ID: <20221130171637.718182-1-james.morse@arm.com> (raw)

Hello!

Changes since the v1
 * Duplicate definition muck up in patch 29 fixed.
 * Rebased onto arm64/for-next/sysregs, which is just rc4.

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...

Thanks to Mark Brown for reviewing all this - it was mind numbing to write,
I'm sure its even worse to review!

This will conflict with Amit's series that adds new HWCAPs for 32bit.
Let me know what I should rebase this onto.

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, and it doesn't mind duplicate entries.

This series is based on v6.1-rc4, and can be retrieved from:
