Subject: [PATCH] mtd: diskonchip: remove unused entries in Kconfig

This patch proposes to remove kernel configuration parameters
defined in drivers/mtd/devices/Kconfig, but used nowhere
in the makefiles and source code (except in comments).

-	  Check for the 0x55 0xAA signature of a DiskOnChip, and do not
-	  continue with probing if it is absent.  The signature will always be
-	  present for a DiskOnChip 2000 or a normal DiskOnChip Millennium.
-	  Only if you have overwritten the first block of a DiskOnChip
-	  Millennium will it be absent.  Enable this option if you are using
-	  LinuxBIOS or if you need to recover a DiskOnChip Millennium on which
-	  you have managed to wipe the first block.
