[Qemu-devel] [PULL v2 05/11] milkymist-vgafb: swap pixel data in source buffer |

In commit fc97bb5ba3e7239c0b6d24095df6784868dfebbf the lduw_raw() call was
eliminated. But we are reading from the target buffer a 16-bit value, which
is in big-endian format. Therefore, swap the bytes if we are building for a
little-endian host.
