Subject: [PATCH RESEND v7 1/9] target/arm: Move cortex sysregs into a separate file
Date: Tue, 28 Feb 2023 16:26:20 -0300 [thread overview]
Message-ID: <20230228192628.26140-2-farosas@suse.de> (raw)
In-Reply-To: <20230228192628.26140-1-farosas@suse.de>
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.
