Per the Physical Layer Simplified Spec. "3.6 Bus Protocol":
There are two types of Data packet format for the SD card.
(1) Usual data (8-bit width): The usual data (8-bit width) are sent in
LSB (Least Significant Byte) first, MSB (Most Significant Byte) last
sequence. But in the individual byte, it is MSB (Most Significant Bit)
first, LSB (Least Significant Bit) last.
(2) Wide width data (SD Memory Register): The wide width data is shifted
from the MSB bit.
Since the SD frames use different byte order, we use the lm32 target
for big-endian qtesting, and aarch64 for the little-endian qtesting.
