This patch alone barely supports APF27, since the resulting U-Boot
cannot be flashed on the board and booted cold; for this it needs the
SPL from patch 3/4. Please merge 2/4 and 3/4.

(aside: I am somewhat surprised that something "reserved for future
use" can be considered "available for customer use": reserved areas
are... reserved... thus probably not available -- future revisions of
the *IC* may actually exercize the reservation, causing a conflict
with the *board* assumptions. But hey, that's not a U-boot issue)

Wouldn't it simplify the code to create a function that initializes one
port passed as an argument with an array of consts passed as a second
argument, then define 6 consts for the 6 ports and call the function 6
times with the right arguments?

This is a reference to the freescale documentation.
It means that customer (here Armadeus) can use it to store
informations.

Yes, this function can be used if it's enable in the u-boot environment.

In fact lowlevel_init isn't only the call of a function, this is also
some "low level" init (like cache). I need this low level init, but
I don't need to call a function, so I only define an empty function.
