Actually there are two parts to it:
bootcount_store() and bootcount_load() are needed for the boot
counter, a generic feature; I tend to move these into
arch/powerpc/lib/bootcount.c; the code also needs to be rewritten to
use I/O accessors.
post_word_store() and post_word_load() is architecture specific,
common POST code that unfortunately also gets used by the logbuffer
code. This should be split. Then we would have
arch/powerpc/lib/logbuf.c and post/arch/powerpc/post_io.c or such.
Please also note that there are more files implementing such code -
see for example here:
board/cm5200/cm5200.c
board/bf537-stamp/post.c
board/barco/barco.c
board/bc3450/bc3450.c
board/ssv/common/post.c
board/tqc/tqm5200/tqm5200.c
board/xes/xpedite1000/xpedite1000.c
Thanks.
Best regards,
Wolfgang Denk

Without facts, the decision cannot be made logically. You must rely
on your human intuition.
