A few more PPC440GP/Ebony cleanups

Hi, here's another step towards getting generic 440GP stuff out of
ebony.h/ebony.c.
At this point ebony.h looks OK to me. For ebony.c, it seems to me
that at least ebony_calibrate_decr(), ebony_find_end_of_memory() and
the PCI setup want to be generic.
Do you think it would be better to create an
arch/ppc/kernel/ppc440_setup.c with library functions like
ppc440_find_end_of_memory() that ebony.c uses, or just turn ebony.c
into ppc440_setup.c and use #ifdefs for new 440GP boards?
Best,
Roland

# The following is the BitKeeper ChangeSet Log
# --------------------------------------------
# 02/05/30 mporter at beef.az.mvista.com 1.1060
# Fix 440GP type 1 config cycle generation. Systems with P2P
# bridges now work.
#
# The 440GP has a lazy host bridge that needs the cycle type
# bit in the CFGA set appropriately for the desired cycle type.
# We now key off a machdep flag to set the cycle type bit as
# needed in the indirect_pci method.

# According to the errata list, the TAU unit on the 7455 reports temperatures
# that are 35 to 55 degrees lower than actual. It also states that the TAU
# is not supported as a feature and is not included in any 7455 documentation.
# Remove from the feature list.
# --------------------------------------------
# 02/06/03 mporter at beef.az.mvista.com 1.1069
# Book E cleanups from Kumar Gala <kumar.gala at motorola.com>.
#
# Added a CONFIG_BOOKE option so in the future as more BOOKE processores/cores
# come out generic code is not duplicated. Currently the only BOOKE part that
# exists is the 440.
#
# Renamed CONFIG_440 to CONFIG_BOOKE in cases where we really are ifdefing
# around BOOKE architecture details, not 440 implementation details.
#
# In the future, we'll use -mbooke if we are CONFIG_BOOKE as well, but
# it's necessary to be at binutils 2.11.90.0.10+ for that and most
# folks are using 2.10-based 4xx binutils at the moment that enable
# all the necessary Book E instructions.
# --------------------------------------------
# 02/06/03 trini at bill-the-cat.bloom.county 1.118.1.526
# According to the 7450 errata sheet (#25) the TAU is not a supported
# feature of any of the 7450s and has been removed from all documentation
# except for the errata sheet, so remove it from the feature list.
