From 8b41c30525a529ee69505909908a704fc134d21b Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 4 Mar 2016 11:30:17 +0000 Subject: sdhci: Implement DeviceClass reset The sdhci device was missing a DeviceClass reset method; implement it. Poweron reset looks the same as reset commanded by the guest via the device registers, apart from modelling of the rpi 'pending insert interrupt on powerup' quirk.
