Subject: [PATCH 1/4] arm: HVC and SMC encodings don't exist for M profile
Date: Mon, 20 Feb 2017 18:41:09 +0000 [thread overview]
Message-ID: <1487616072-9226-2-git-send-email-peter.maydell@linaro.org> (raw)
In-Reply-To: <1487616072-9226-1-git-send-email-peter.maydell@linaro.org>
M profile doesn't have the HVC or SMC encodings, so make them always
UNDEF rather than generating calls to helper functions that assume
A/R profile.
