[U-Boot] [PATCH] powerpc: Consolidate bootcount_{store|load} for PowerPC

[Detlev Zundel <dzu@denx.de>]

Hi Stefan,

> This patch consolidates bootcount_{store|load} for PowerPC by
> implementing a common version in arch/powerpc/lib/bootcount.c. This
> code is now used by all PowerPC variants that currently have these
> functions implemented.
>
> The functions now use the proper IO-accessor functions to read/write the
> values.
>
> This code also supports two different bootcount versions:
>
> a) Use 2 seperate words (2 * 32bit) to store the bootcounter
> b) Use only 1 word (2* 16bit) to store the bootcounter
>
> Version b) was already used by MPC5xxx.

Cool, thanks!

I have only a cosmetic suggestion - can we rename the option
CONFIG_SYS_BOOTCOUNT_USE_32BIT to CONFIG_SYS_BOOTCOUNT_SINGLEWORD?
According to your documentation this would describe the situation
somewhat closer.

Apart from that:
