   4 Subject: [PATCH 136/203] mtd: nand: pxa3xx: Use chip->cmdfunc instead of the
   5  internal
   6
   7 Whenever possible, it's always better to use the generic chip->cmdfunc
   8 instead of the internal pxa3xx_nand_cmdfunc().
   9 In this particular case, this will allow to have multiple cmdfunc()
  10 implementations for different SoC variants.
