Subject: [PATCH RFC 1/2] m68k/atari: add platform device for Falcon IDE port
Date: Fri, 21 Jun 2019 08:47:21 +1200 [thread overview]
Message-ID: <1561063642-13900-2-git-send-email-schmitzmic@gmail.com> (raw)
In-Reply-To: <CAMuHMdUcUqWWGNngNV3EpEq5wSsf5qTVeZvTB9gX1e26Jrq1xA@mail.gmail.com>
Autoloading of Falcon IDE driver modules requires converting
these drivers to platform drivers.
Add platform device for Falcon IDE interface in Atari platform
setup code in preparation for this.
Add Falcon IDE base address in Atari hardware address header.
