From 8c4d239139e93268884f9d385a0966ef40db422f Mon Sep 17 00:00:00 2001 From: Bernhard Beschow Date: Sun, 14 Jan 2024 13:39:07 +0100 Subject: [PATCH] hw/block/fdc-isa: Implement relocation and enabling/disabling for TYPE_ISA_FDC The real SuperI/O chips emulated by QEMU allow for relocating and enabling or disabling their SuperI/O functions via software. So far this is not implemented. Prepare for that by adding isa_fdc_set_{enabled,iobase}. Signed-off-by: Bernhard Beschow Message-Id: <20240114123911.4877-8-shentey@gmail.com> Reviewed-by: Michael S.
