CONFIG_OF_FLAT_TREE
New kernel versions are expecting firmware settings to be
passed using flat open firmware trees.
The environment variable "disable_of", when set, disables this
functionality.
CONFIG_OF_FLAT_TREE_MAX_SIZE
The maximum size of the constructed OF tree.
OF_CPU - The proper name of the cpus node.
OF_TBCLK - The timebase frequency.
