Dear Anatolij Gustschin,
This patch consolidates bootcount_{store|load} for ARM by implementing a common version in arch/arm/lib/bootcount.c. This code is now used by all ARM variants that currently have these functions implemented.
Also supports two different bootcount versions:
a) Use 2 separate words (2 * 32bit) to store the bootcounter b) Use only 1 word (2 * 16bit) to store the bootcounterThe latter was already used by AT91.
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...
