From ac7018614dd958c68ffbb67e8eb6826e1533b96e Mon Sep 17 00:00:00 2001 From: Willy Tarreau Date: Sun, 1 Mar 2020 20:55:53 +0100 Subject: floppy: introduce new functions fdc_inb() and fdc_outb() These two functions replace fd_inb() and fd_outb() in that they take the FDC in argument. This will ease the separation of the base address and the port everywhere the code is used.
