[Qemu-devel] [PATCH v4 01/20] 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 <address@hidden>
 and Peter Ogden <address@hidden> from qemu/xilinx tag xilinx-v2015.4]
