[Qemu-devel] [PATCH v13 02/30] sdhci: add qtest to check the SD capabili


From: Philippe Mathieu-Daudé
Subject: [Qemu-devel] [PATCH v13 02/30] sdhci: add qtest to check the SD capabilities register
Date: Tue, 13 Feb 2018 01:07:41 -0300

The PCI model is tested with the pc/x86_64 machine,
the SysBus model with the smdkc210/arm machine.
