[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.
