      powerpc: Consolidate bootcount_{store|load} for PowerPC · e4a95d11
      Stefan Roese authored
      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 separate 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.
