From eb4f566bbbe195b2475e8fa5d9ed29ca56a18b02 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Thu, 18 Feb 2016 14:16:18 +0000 Subject: [PATCH] sdhci_sysbus: Create SD card device in users, not the device itself Move the creation of the SD card device from the sdhci_sysbus device itself into the boards that create these devices. This allows us to remove the cannot_instantiate_with_device_add notation because we no longer call drive_get_next in the device model.
