Subject: [PATCH 02/23] floppy: add references to 82077's extra registers
Date: Tue, 31 Mar 2020 11:40:33 +0200 [thread overview]
Message-ID: <20200331094054.24441-3-w@1wt.eu> (raw)
In-Reply-To: <20200331094054.24441-1-w@1wt.eu>
This controller provides extra status registers SRA and SRB as well
as a tape drive register (TDR) and a data rate select register (DSR),
which are referenced in the sparc port, so let's have their symbolic
definitions centralized.
