More specific: only AT91SAM9260. There are many more AT91 SoCs
that might want to use bootcount in the future!
The more I think about it, the less sense it makes to move
bootcount access to arm/lib:
Handling bootcount is very SoC (maybe even board, if the SoC has no
nonvolatile storage) and definitely not ARM specific.
Moving it from ARM-SoC specific files to a common ARM-lib file will
cause many conditional compiles there.
The arch/powerpc/lib/bootcount.c is an example how the arm/lib/bootcount.c
is going to look like in the long run.

PS: your bootcount.c misses the GPL header...
