[PATCH v1 0/2] board: toradex: improve env badblock management for NAND variant boards

[Francesco Dolcini]

Use the complete 512kb (4 blocks) nand partition reserved for u-boot
environment instead of just the first block, this allows the module
to have a working environment even if 3 blocks are bad.

Applied to u-boot-imx, master, thanks !

Sure, but is it not time to move CONFIG_ENV_RANGE into Kconfig (and drop 
it from whitelist= ?

I'll try to have a look at it later tonight, I cannot warrant anything at the
moment.

So, I gave it a try, but it is not trivial (CONFIG_ENV_RANGE is using most of
the time other CONFIG options that are not in kconfig yet) :-/

At the moment I have no much time to invest on this topic, I hope it would be fine
to merge these 2 patches as they are.

Ok, I will merge your patches into u-boot-imx.
