[PATCH 27/27] target/ppc: Move common SPR functions out of cpu_init |
|
Date: |
Tue, 15 Feb 2022 18:41:48 -0300 |
Let's leave cpu_init with just generic CPU initialization and
QOM-related functions.
The rest of the SPR registration functions will be moved in the
following patches along with the code that uses them. These are only
the commonly used ones.
