ee7883b746 [Blackfin] arch: fix bug kernel boot message: memory information is not reasonable 
Some of the information in kernel boot message is not reasonable.
http://blackfin.uclinux.org/gf/project/uclinux-dist/tracker/?action=TrackerItemEdit&tracker_item_id=3846

 - use _rambase as the start of kernel image.
   kernel is in the region [_rambase, _ramstart]
 - count in pages in per-cpu-page list as available memory
 - reserved memory now include: [0 - 4K] for bad pointer catching,
   memory reserved for abnormaly 05000263, memory reserved by kernel itself.

fac3cf432e [Blackfin] arch: Fix gpio label handling 
early serial init also utilizes the peripheral request api - however
at this point bfin_gpio_init didn't allocate memory for the labels.
So we always have two zombies (allocated pin functions without labels)

This happens before the initcalls - We now allocate memory statically.
Define MAX_RESOURCES individually for each cpu.
