[Qemu-devel] [PATCH v3 01/18] sdcard: Don't always set the high capacity bit

[Philippe Mathieu-Daudé]

Don't set the high capacity bit by default as it will be set if required
in the sd_set_csd() function.

[based on a patch from Alistair Francis <alistair.fran...@xilinx.com>
 and Peter Ogden <og...@xilinx.com> from qemu/xilinx tag xilinx-v2015.4]
