It does not. On the ICU862 the U-Boot image is at the lower end of
the enfironment, while the environment is at the upper end (IIRC this
board uses top boot sector flash memory). The environment does NOT
get installed when installing the U-Boot image. So there is no need
to put any initialized data in it.
It will be initialized as soon as the user types "saveenv" for the
first time. Until then, the default environment is used.
