+	  This enables support for reading, writing and locking so called
+	  "Protection Registers" present on some flash chips.
+	  A subset of them are pre-programmed at the factory with a
+	  unique set of values. The rest is user-programmable.
+
+	  The user-programmable Protection Registers contain one-time
+	  programmable (OTP) bits; when programmed, register bits cannot be
+	  erased. Each Protection Register can be accessed multiple times to
+	  program individual bits, as long as the register remains unlocked.
+
+	  Each Protection Register has an associated Lock Register bit. When a
+	  Lock Register bit is programmed, the associated Protection Register
+	  can only be read; it can no longer be programmed. Additionally,
+	  because the Lock Register bits themselves are OTP, when programmed,
+	  Lock Register bits cannot be erased. Therefore, when a Protection
+	  Register is locked, it cannot be unlocked.
+
+	  This feature should therefore be used with extreme care. Any mistake
+	  in the programming of OTP bits will waste them.

-The ELAN-104NC has up to 8 Mibyte of Intel StrataFlash (28F320/28F640) in x16
-mode.  This drivers uses the CFI probe and Intel Extended Command Set drivers.
-
-The flash is accessed as follows:
-
-   32 kbyte memory window at 0xb0000-0xb7fff
-   
-   16 bit I/O port (0x22) for some sort of paging.
-
-The single flash device is divided into 3 partition which appear as separate
-MTD devices.
-
-Linux thinks that the I/O port is used by the PIC and hence check_region() will
-always fail.  So we don't do it.  I just hope it doesn't break anything.

+ *  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.
