If we do this, we should try to move all bootcounter implementations
to this file, see:

[hs at pollux u-boot]$ grep -lr bootcount_store .
./common/main.c
./arch/powerpc/lib/bootcount.c
./arch/arm/cpu/arm926ejs/at91/cpu.c
./arch/arm/cpu/armv7/highbank/bootcount.c
./arch/arm/cpu/ixp/cpu.c
./arch/blackfin/cpu/bootcount.c
./board/enbw/enbw_cmc/enbw_cmc.c
./board/omicron/calimain/calimain.c
./board/keymile/km_arm/km_arm.c
./include/common.h
[hs at pollux u-boot]$

and should provide a possibility to add board specific code,
for example needed for the

board/keymile/km_arm/km_arm.c boards.

Have you done a "MAKEALL arm"? I think (didn;t tried it) this
would fail with your patch ...

bye,
Heiko
