Bootloader detection on Colibri iMX6ULL 512MB (NAND)

[griloHBG]

Although I have U-boot installed, the logic used to get the bootloader on Colibri iMX6ULL 512MB (NAND) is giving me "Unknown" bootloader:

But works as expected on Apalis iMX6D 512MB (eMMC)

Probably all NAND based modules are presenting the same behavior.

Thanks, @griloHBG. We'll need to think about a fix for NAND modules... do you have something that would fix it?
