Subject: [PATCH 2/4] target/ppc: Tidy POWER book4 SPR registration
Date: Sun, 4 Jun 2023 09:36:10 +1000 [thread overview]
Message-ID: <20230603233612.125879-3-npiggin@gmail.com> (raw)
In-Reply-To: <20230603233612.125879-1-npiggin@gmail.com>
POWER book4 (implementation-specific) SPRs are sometimes in their own
functions, but in other cases are mixed with architected SPRs. Do some
spring cleaning on these.
