From 1b986676eb472e41dfff7c946adb14552ebb3c23 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Tue, 20 Feb 2024 09:55:01 +0100 Subject: hw/ide: Move IDE DMA related definitions to a separate header ide-dma.h MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit These definitions are required outside of the hw/ide/ code, too, so lets's move them from internal.h to a new header called ide-dma.h.
