Subject: aarch64: clear CTI halt event early at debug entry
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=332d66c75a89516750726f1a9d2b65a624037770;p=openocd

aarch64: clear CTI halt event early at debug entry

The halt event was left pending in the CTI, better to clear it immediately
after debug entry.
