Marek,

I suppose it depends on when in SPL you need env. I assume memory
controller is about the first thing done after things like iomux. If
this is a problem then at least nand env (env_nand.c) is broken too as
that's where I got my inspiration for this after I realized I was
hanging due to not having enough stack space.

It looks like Tom may have a solution that I'll look at.
