[U-Boot] [ARM] Environment variables not available during, console initialisation?

[Derek Ou]

Is this a catch 22?  If console is initialized after loading environment 
variables, this
means NAND (or other memories) driver are loaded before console being 
available
and there is no console output to debug NAND driver initialization.  If 
console is
initialized before loading NAND driver, environment variable is 
available after the
console is configured?
