From 2c6b9f20b1c4b639d82188a70b63b7638249b909 Mon Sep 17 00:00:00 2001 From: Aurelien Jarno Date: Thu, 20 Jan 2011 21:40:53 +0100 Subject: [PATCH] gt64xxx: set isa_mem_base during registration isa_mem_base is computed from registers during reset, but due to QEMU limitations some devices (e.g. VGA card) need to know it earlier when they are registered. Workaround this by setting the value during registration instead of reset.
