  at risk of adding another question to this earlier post, my build of
a core-image-minimal worked, and among other generated artifacts in
images/beaglebone/, i have the files:

 * MLO -> MLO-beaglebone-2013.10-r0+gitrAUTOINC+183acb7003
 * u-boot-spl.bin-beaglebone-2013.10-r0+gitrAUTOINC+183acb7003

which are very close in size. i'm used to just installing the MLO
file, so what's the difference here? what am i supposed to do with the
"spl" file?
