Subject: [PATCH 08/23] floppy: use symbolic register names in the x86 port
Date: Tue, 31 Mar 2020 11:40:39 +0200 [thread overview]
Message-ID: <20200331094054.24441-9-w@1wt.eu> (raw)
In-Reply-To: <20200331094054.24441-1-w@1wt.eu>
Now we can use FD_STATUS and FD_DATA instead of 4 or 5, let's do
this, and also use STATUS_DMA and STATUS_READY for the status bits.
