      Implement memory accessor interface in the MTD layer which enables the
      kernel to access flash data.
      
      This patch adds two new members to the mtd_partition structure, a function
      handler which will be called during setup of the partition and an argument
      to be passed to this setup function.
      
      Example:
      +static struct mtd_partition spi_flash_partitions[] = {
      +       [0] = {
      +               .name       = "U-Boot",
      +               .offset     = 0,
      +               .size       = SZ_256K,
      +               .mask_flags = MTD_WRITEABLE,
      +       },
      +       [1] = {
      +               .name       = "U-Boot Environment",
      +               .offset     = MTDPART_OFS_NXTBLK,
      +               .size       = SZ_64K,
      +               .mask_flags = MTD_WRITEABLE,
      +       },
      +       [2] = {
      +               .name       = "Linux",
      +               .offset     = MTDPART_OFS_NXTBLK,
      +               .size       = SZ_7M,
      +               .mask_flags = 0,
      +       },
      +       [3] = {
      +               .name       = "MAC Address",
      +               .offset     = MTDPART_OFS_NXTBLK,
      +               .size       = SZ_64K,
      +               .mask_flags = 0,
      +               .setup      = davinci_get_mac_addr,
      +               .context    = (void *)0,
      +       },
      +};
      
      The davinci_get_mac_addr function reads the MAC address from
      offset ZERO of last MTD partition.
