From d4614cc3121b3c6375a63d01947779e36149c68c Mon Sep 17 00:00:00 2001 From: =?utf8?q?Andreas=20F=C3=A4rber?= Date: Thu, 6 Jun 2013 15:41:10 +0200 Subject: [PATCH] usb/hcd-ehci: Split off instance_init from realize MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This makes the mem MemoryRegion available to derived instance_inits. Keep the bus in realize for now since naming breaks in instance_init.
