Ha, good point. I should've written the 'SPL' file instead, which is
just the SPL without U-Boot. I don't want to install U-Boot to random
offset on the SD card as it has the potential to corrupt data if the
u-boot binary changes in size.

If I install u-boot image to random offset 138 blocks from the start of
SD card, it will boot that, otherwise it will load from FS.

I will update the commit message with the correct info, sorry.
