SD Card
^^^^^^^
To write an image that boots from a SD card first create a FAT32 partition
and a FAT32 filesystem on the SD card::
sudo fdisk /dev/sdx
sudo mkfs.vfat -F 32 /dev/sdx1
Mount the SD card and copy the SPL and U-Boot to the root directory of the
SD card::
sudo mount -t vfat /dev/sdx1 /mnt
sudo cp spl/boot.bin /mnt
sudo cp u-boot.img /mnt
