  *  05-19-2004  tglx: Basic support for Renesas AG-AND chips

  *  09-24-2004  tglx: add support for hardware controllers (e.g. ECC) shared
- *		among multiple independend devices. Suggestions and initial patch

- *  12-05-2004	dmarlin: add workaround for Renesas AG-AND chips "disturb" issue.
- *		Basically, any block not rewritten may lose data when surrounding blocks
- *		are rewritten many times.  JFFS2 ensures this doesn't happen for blocks
- *		it uses, but the Bad Block Table(s) may not be rewritten.  To ensure they
- *		do not lose data, force them to be rewritten when some of the surrounding
- *		blocks are erased.  Rather than tracking a specific nearby block (which
- *		could itself go bad), use a page address 'mask' to select several blocks
- *		in the same area, and rewrite the BBT when any of them are erased.
- *
- *  01-03-2005	dmarlin: added support for the device recovery command sequence for Renesas
- *		AG-AND chips.  If there was a sudden loss of power during an erase operation,
- * 		a "device recovery" operation must be performed when power is restored
- * 		to ensure correct operation.
- *
- *  01-20-2005	dmarlin: added support for optional hardware specific callback routine to
- *		perform extra error status checks on erase and write failures.  This required
- *		adding a wrapper function for nand_read_ecc.
