Subject: [PATCH v10 03/11] target/arm: Extract TCG -cpu max code into a function
Date: Wed, 12 Apr 2023 09:18:21 -0300	[thread overview]
Message-ID: <20230412121829.14452-4-farosas@suse.de> (raw)
In-Reply-To: <20230412121829.14452-1-farosas@suse.de>

Introduce aarch64_max_tcg_initfn that contains the TCG-only part of
-cpu max configuration. We'll need that to be able to restrict this
code to a TCG-only config in the next patches.
