Subject: [PATCH 15/20] nubus: move NubusBus from mac-nubus-bridge to nubus-bridge
Date: Sun, 12 Sep 2021 08:49:09 +0100	[thread overview]
Message-ID: <20210912074914.22048-16-mark.cave-ayland@ilande.co.uk> (raw)
In-Reply-To: <20210912074914.22048-1-mark.cave-ayland@ilande.co.uk>

Now that Nubus has its own address space rather than mapping directly into the
system bus, move the Nubus reference from MacNubusBridge to NubusBridge.
