Subject: [PATCH v6 05/24] target/arm: Move cortex impdef sysregs to cpu_tcg.c
Date: Fri,  6 May 2022 13:02:23 -0500	[thread overview]
Message-ID: <20220506180242.216785-6-richard.henderson@linaro.org> (raw)
In-Reply-To: <20220506180242.216785-1-richard.henderson@linaro.org>

Previously we were defining some of these in user-only mode,
but none of them are accessible from user-only, therefore
define them only in system mode.

This will shortly be used from cpu_tcg.c also.
