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).

	  This option allows you to specify nonstandard address at which to

	  probe for a DiskOnChip, or to change the detection options.  You

	  are unlikely to need any of this unless you are using LinuxBIOS.

	  Say 'N'.

	default "0x0"

	---help---

	  By default, the probe for DiskOnChip devices will look for a

	  DiskOnChip at every multiple of 0x2000 between 0xC8000 and 0xEE000.

	  This option allows you to specify a single address at which to probe

	  for the device, which is useful if you have other devices in that

	  range which get upset when they are probed.



	  (Note that on PowerPC, the normal probe will only check at

	  0xE4000000.)



	  Normally, you should leave this set to zero, to allow the probe at

	  the normal addresses.



config MTD_DOCPROBE_HIGH

	bool "Probe high addresses"

	help

	  By default, the probe for DiskOnChip devices will look for a

	  DiskOnChip at every multiple of 0x2000 between 0xC8000 and 0xEE000.

	  This option changes to make it probe between 0xFFFC8000 and

	  0xFFFEE000.  Unless you are using LinuxBIOS, this is unlikely to be

	  useful to you.  Say 'N'.



config MTD_DOCPROBE_55AA

	bool "Probe for 0x55 0xAA BIOS Extension Signature"

	depends on MTD_DOCPROBE_ADVANCED

	help

	  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.
