From: Matthias Welwarsky Date: Thu, 1 Sep 2016 19:14:46 +0000 (+0200) Subject: aarch64: make DCC read/write functions operate on struct armv8_common X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=db97bb4a9dbc210b599dc5acc58696ea22eee0da;p=openocd aarch64: make DCC read/write functions operate on struct armv8_common Change the signature of aarch64_(read|write)_dcc[_64] to take a "struct armv8_common *" as the context to operate on. No functional change.
