Nikolay,

You are correct in that the Gateworks Ventana boards use SPL (to
configure MMDC/DDR3) and u-boot.img (which I suppose technically could
be called a Tertiary Program Loader or TPL). Marek's board here looks
to be doing the same thing.

I believe TPL commonly refers to something else in the u-boot
community, but I'm not clear why. In the IMX6 world, the Primary Boot
Loader, or PBL is the IMX6 BOOT ROM firmware.

I would love to clear up this terminology in order to properly
document it for my users.
