From 5ed0794cde59365d4d5895b89bb2f7ef7ffdbd55 Mon Sep 17 00:00:00 2001 From: Michael Schmitz Date: Wed, 6 Nov 2019 15:47:29 +1300 Subject: m68k/atari: Convert Falcon IDE drivers to platform drivers 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. Use this in the pata_falcon driver in place of the simple platform device set up on the fly. Convert falconide driver to use the same platform device that is used by pata_falcon also. (With the introduction of a platform device for the Atari Falcon IDE interface, the old Falcon IDE driver no longer loads (resource already claimed by the platform device)). Tested (as built-in driver) on my Atari Falcon.
