   4 Subject: [PATCH 149/203] mtd: nand: pxa3xx: Fix SEQIN column address set
   5
   6 This commit adds support page programming with a non-zero "column"
   7 address setting. This is important to support OOB writing, through
   8 command sequences such as:
   9
  10   cmdfunc(mtd, NAND_CMD_SEQIN, mtd->writesize, ofs);
  11   write_buf(mtd, oob_buf, 6);
  12   cmdfunc(mtd, NAND_CMD_PAGEPROG, -1, -1);
