[PATCH v11 01/13] target/arm: Move cortex sysregs into a separate file |
|
Date: |
Wed, 26 Apr 2023 15:00:01 -0300 |
The file cpu_tcg.c is about to be moved into the tcg/ directory, so
move the register definitions into a new file.
Also move the function declaration to the more appropriate cpregs.h.
