hw/sd/sdcard: Support boot area in emmc image
This assumes a specially constructed image:
$ dd if=/dev/zero of=mmc-bootarea.img count=2 bs=1M
$ dd if=u-boot-spl.bin of=mmc-bootarea.img conv=notrunc
$ dd if=u-boot.bin of=mmc-bootarea.img conv=notrunc count=64 bs=1K
$ cat mmc-bootarea.img obmc-phosphor-image.wic > mmc.img
$ truncate --size 16GB mmc.img
For now this still requires a mtd image to load the SPL:
$ qemu-system-arm -M tacoma-bmc -nographic \
-global driver=sd-card,property=emmc,value=true \
-drive file=mmc.img,if=sd,index=2,format=raw
