Subject: [Qemu-devel] [PULL 1/8] target-arm: Allow special cpregs to have flags set
Date: Tue, 25 Jun 2013 18:33:05 +0100 [thread overview]
Message-ID: <1372181592-32170-2-git-send-email-peter.maydell@linaro.org> (raw)
In-Reply-To: <1372181592-32170-1-git-send-email-peter.maydell@linaro.org>
Relax the "is this a valid ARMCPRegInfo type value?" check to permit
"special" cpregs to have flags other than ARM_CP_SPECIAL set. At
the moment none of the other flags are relevant for special regs,
but the migration related flag we're about to introduce can apply
here too.
