Could you do it, please? I will not have time for that ATM. :(

bootpart is the right name I think, we just need to update it after loading our
script.

I found the problem. U-boot already defines loadfdt:
echo $loadfdt
load mmc ${bootpart} ${fdtaddr} ${bootdir}/${fdtfile}
Do we want to change our var name our do we overwrite loadfdt?
I think overwriting a u-boot var is not a good idea. Moreover, why do we have 2
vars: usefdt and loadfdt? if we want to use DT, we must load it. And we do not
need to load it if we do not use it. Isn't it?
I would like to remove loadfdt and only use usefdt. Are you ok?
