[Qemu-devel] [PULL 19/32] sdcard: fix the 'maximum data transfer rate' to 25MHz |

From: Philippe Mathieu-Daudé <address@hidden>
To comply with Spec v1.10 (and 2.00, 3.01):
. TRAN_SPEED
for current SD Memory Cards that field must be always 0_0110_010b (032h) which
is
equal to 25MHz - the mandatory maximum operating frequency of SD Memory Card.
