MTD debugging support
CONFIG_MTD_DEBUG
This turns on low-level debugging for the entire MTD sub-system.
+ Normally, you should say 'N'.
+
+MTD partitioning support
+CONFIG_MTD_PARTITIONS
+ If you have a device which needs to divide its flash chip(s) up
+ into multiple 'partitions', each of which appears to the user as
+ a separate MTD device, you require this option to be enabled. If
+ unsure, say 'Y'.
+
+ Note, however, that you don't need this option for the DiskOnChip
+ devices. Partitioning on NFTL 'devices' is a different - that's the
+ 'normal' form of partitioning used on a block device.
+
+RedBoot partition table parsing
+CONFIG_MTD_REDBOOT_PARTS
+ RedBoot is a ROM monitor and bootloader which deals with multiple
+ 'images' in flash devices by putting a table in the last erase
+ block of the device, similar to a partition table, which gives
+ the offsets, lengths and names of all the images stored in the
+ flash.
+
+ If you need code which can detect and parse this table, and register
+ MTD 'partitions' corresponding to each image in the table, enable
+ this option.
+
+ You will still need the parsing functions to be called by the driver
+ for your particular device. It won't happen automatically. The
+ SA1100 map driver (CONFIG_MTD_SA1100) has an option for this, for
+ example.
+
+Compaq bootldr partition table parsing

MTD debugging verbosity
CONFIG_MTD_DEBUG_VERBOSE
Determines the verbosity level of the MTD debugging messages.
-M-Systems Disk-On-Chip 1000 support
-CONFIG_MTD_DOC1000
- This provides an MTD device driver for the M-Systems DiskOnChip
- 1000 devices, which are obsolete so you probably want to say 'N'.
-M-Systems Disk-On-Chip 2000 and Millennium support
-CONFIG_MTD_DOC2000
- This provides an MTD device driver for the M-Systems DiskOnChip
- 2000 and Millennium devices. Originally designed for the DiskOnChip
- 2000, it also now includes support for the DiskOnChip Millennium.
- If you have problems with this driver and the DiskOnChip Millennium,
- you may wish to try the alternative Millennium driver below. To use
- the alternative driver, you will need to undefine DOC_SINGLE_DRIVER
- in the drivers/mtd/docprobe.c source code.
+Direct chardevice access to MTD devices
+CONFIG_MTD_CHAR
+ This provides a character device for each MTD device present in
+ the system, allowing the user to read and write directly to the
+ memory chips, and also use ioctl() to obtain information about
+ the device, or to erase parts of it.
- If you use this device, you probably also want to enable the NFTL
- 'NAND Flash Translation Layer' option below, which is used to emulate
- a block device by using a kind of filesystem on the flash chips.
+Caching block device access to MTD devices
+CONFIG_MTD_BLOCK
+ Although most flash chips have an erase size too large to be useful
+ as block devices, it is possible to use MTD devices which are based
+ on RAM chips in this manner. This block device is a user of MTD devices
+ performing that function.
+
+ At the moment, it is also required for the Journalling Flash File
+ System(s) to obtain a handle on the MTD device when it's mounted
+ (although JFFS and JFFS2 don't actually use any of the functionality
+ of the mtdblock device).
-Alternative Disk-On-Chip Millennium support
-CONFIG_MTD_DOC2001
- This provides an alternative MTD device driver for the M-Systems
- DiskOnChip Millennium devices. Use this if you have problems with
- the combined DiskOnChip 2000 and Millennium driver above. To get
- the DiskOnChip probe code to load and use this driver instead of
- the other one, you will need to undefine DOC_SINGLE_DRIVER near
- the beginning of drivers/mtd/docprobe.c
+ Later, it may be extended to perform read/erase/modify/write cycles
+ on flash chips to emulate a smaller block size. Needless to say,
+ this is very unsafe, but could be useful for filesystems which are
+ almost never written to.
- If you use this device, you probably also want to enable the NFTL
- 'NAND Flash Translation Layer' option below, which is used to emulate
- a block device by using a kind of filesystem on the flash chips.
+ You do not need this option for use with the DiskOnChip devices. For
+ those, enable NFTL support (CONFIG_NFTL) instead.
-Ramix PMC551 PCI Mezzanine ram card support
-CONFIG_MTD_PMC551
- This provides a MTD device driver for the Ramix PMC551 RAM PCI card
- from Ramix Inc. (http://www.ramix.com/products/memory/pmc551.html).
- These devices come in memory configurations from 32M - 1G. If you
- have one, you probably want to enable this.
+Readonly block device access to MTD devices
+CONFIG_MTD_BLOCK_RO
+ This allows you to mount read-only filesystems (such as cramfs) from
+ an MTD device, without the overhead (and danger) of the caching
+ driver.
- If this driver is compiled as a module you get the ability to select the
- size of the aperture window pointing into the devices memory. What this
- means is that if you have a 1G card, normally the kernel will use a 1G
- memory map as it's view of the device. As a module, you can select a
- 1M window into the memory and the driver will "slide" the window around
- the PMC551's memory. This was particularly useful on the 2.2 kernels
- on PPC architectures as there was limited kernel space to deal with.
+ You do not need this option for use with the DiskOnChip devices. For
+ those, enable NFTL support (CONFIG_NFTL) instead.
-Use extra onboard system memory as MTD device
-CONFIG_MTD_SLRAM
- If your CPU cannot cache all of the physical memory in your machine,
- you can still use it for storage or swap by using this driver to
- present it to the system as a Memory Technology Device.
+FTL (Flash Translation Layer) support
+CONFIG_FTL
+ This provides support for the original Flash Translation Layer which
+ is part of the PCMCIA specification. It uses a kind of pseudo-
+ filesystem on a flash device to emulate a block device with 512-byte
+ sectors, on top of which you put a 'normal' filesystem.
-PMC551 256M DRAM Bugfix
-CONFIG_MTD_PMC551_BUGFIX
- Some of Ramix's PMC551 boards with 256M configurations have invalid
- column and row mux values. This option will fix them, but will break
- other memory configurations. If unsure say N.
+ You may find that the algorithms used in this code are patented
+ unless you live in the Free World where software patents aren't
+ legal - in the USA you are only permitted to use this on PCMCIA
+ hardware, although under the terms of the GPL you're obviously
+ permitted to copy, modify and distribute the code as you wish. Just
+ not use it.
-PMC551 Debugging
-CONFIG_MTD_PMC551_DEBUG
- This option makes the PMC551 more verbose during it's operation and is
- only really useful if you are developing on this driver or suspect a
- possible hardware or driver bug. If unsure say N.
+NFTL (NAND Flash Translation Layer) support
+CONFIG_NFTL
+ This provides support for the NAND Flash Translation Layer which is
+ used on M-Systems' DiskOnChip devices. It uses a kind of pseudo-
+ filesystem on a flash device to emulate a block device with 512-byte
+ sectors, on top of which you put a 'normal' filesystem.
-Debugging RAM test driver
-CONFIG_MTD_MTDRAM
- This enables a test MTD device driver which uses vmalloc() to
- provide storage. You probably want to say 'N' unless you're
- testing stuff.
+ You may find that the algorithms used in this code are patented
+ unless you live in the Free World where software patents aren't
+ legal - in the USA you are only permitted to use this on DiskOnChip
+ hardware, although under the terms of the GPL you're obviously
+ permitted to copy, modify and distribute the code as you wish. Just
+ not use it.
+
+Write support for NFTL (EXPERIMENTAL)
+CONFIG_NFTL_RW
+ If you're lucky, this will actually work. Don't whinge if it doesn't.
+ Send mail to the MTD mailing list <linux-mtd@lists.infradead.org> if
+ you want to help to make it more reliable.

-FTL (Flash Translation Layer) support
-CONFIG_FTL
- This provides support for the original Flash Translation Layer which
- is part of the PCMCIA specification. It uses a kind of pseudo-
- file system on a flash device to emulate a block device with 512-byte
- sectors, on top of which you put a 'normal' file system. You may find
- that the algorithms used in this code are patented unless you live
- in the Free World where software patents aren't legal - in the USA
- you are only permitted to use this on PCMCIA hardware, although
- under the terms of the GPL you're obviously permitted to copy,
- modify and distribute the code as you wish. Just not use it.
+M-Systems Disk-On-Chip 2000 and Millennium support

+ 2000, it also now includes support for the DiskOnChip Millennium.
+ If you have problems with this driver and the DiskOnChip Millennium,

+ the alternative driver, you will need to undefine DOC_SINGLE_DRIVER
+ in the drivers/mtd/devices/docprobe.c source code.
-NFTL (NAND Flash Translation Layer) support

+ If you use this device, you probably also want to enable the NFTL
+ 'NAND Flash Translation Layer' option below, which is used to emulate
+ a block device by using a kind of filesystem on the flash chips.

+Alternative Disk-On-Chip Millennium support
+CONFIG_MTD_DOC2001
+ This provides an alternative MTD device driver for the M-Systems
+ DiskOnChip Millennium devices. Use this if you have problems with
+ the combined DiskOnChip 2000 and Millennium driver above. To get
+ the DiskOnChip probe code to load and use this driver instead of
+ the other one, you will need to undefine DOC_SINGLE_DRIVER near
+ the beginning of drivers/mtd/devices/docprobe.c
+
+ If you use this device, you probably also want to enable the NFTL
+ 'NAND Flash Translation Layer' option below, which is used to emulate

+
+Probe for DiskOnChip devices
+CONFIG_MTD_DOCPROBE
+ This isn't a real config option, it's derived.
+
+Advanced detection options for DiskOnChip
+CONFIG_MTD_DOCPROBE_ADVANCED
+ This option allows you to specify nonstandard address at which to
+ probe for a DiskOnChip, or to change the detection options. You're
+ unlikely to need any of this unless you're using LinuxBIOS. Say 'N'.
+
+Probe for 0x55 0xAA BIOS Extension Signature.
+CONFIG_MTD_DOCPROBE_55AA
+ 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.
+
+Physical address of DiskOnChip
+CONFIG_MTD_DOCPROBE_ADDRESS
+ 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're 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.
+
+Probe high addresses
+CONFIG_MTD_DOCPROBE_HIGH
+ 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're using LinuxBIOS, this is unlikely to be useful to you. Say 'N'.
+
+Ramix PMC551 PCI Mezzanine ram card support
+CONFIG_MTD_PMC551
+ This provides a MTD device driver for the Ramix PMC551 RAM PCI card
+ from Ramix Inc. (http://www.ramix.com/products/memory/pmc551.html).
+ These devices come in memory configurations from 32M - 1G. If you
+ have one, you probably want to enable this.
+
+ If this driver is compiled as a module you get the ability to select the
+ size of the aperture window pointing into the devices memory. What this
+ means is that if you have a 1G card, normally the kernel will use a 1G
+ memory map as it's view of the device. As a module, you can select a
+ 1M window into the memory and the driver will "slide" the window around
+ the PMC551's memory. This was particularly useful on the 2.2 kernels
+ on PPC architectures as there was limited kernel space to deal with.
+
+PMC551 256M DRAM Bugfix
+CONFIG_MTD_PMC551_BUGFIX
+ Some of Ramix's PMC551 boards with 256M configurations have invalid column
+ and row mux values. This option will fix them, but will break other memory
+ configurations. If unsure say N.
+
+PMC551 Debugging
+CONFIG_MTD_PMC551_DEBUG
+ This option makes the PMC551 more verbose during it's operation and is only
+ really usefull if you are developing on this driver or suspect a possible
+ hardware or driver bug. If unsure say N.
+
+Use extra onboard system memory as MTD device
+CONFIG_MTD_SLRAM
+ If your CPU cannot cache all of the physical memory in your machine,
+ you can still use it for storage or swap by using this driver to
+ present it to the system as a Memory Technology Device.
+
+Debugging RAM test driver
+CONFIG_MTD_MTDRAM
+ This enables a test MTD device driver which uses vmalloc() to
+ provide storage. You probably want to say 'N' unless you're
+ testing stuff.
+
+MTDRAM erase block size in KiB
+CONFIG_MTDRAM_ERASE_SIZE
+ This allows you to configure the size of the erase blocks in the
+ device emulated by the MTDRAM driver. If the MTDRAM driver is built
+ as a module, it is also possible to specify this as a parameter when
+ loading the module.
+
+MTDRAM device size in KiB
+CONFIG_MTDRAM_TOTAL_SIZE
+ This allows you to configure the total size of the MTD device
+ emulated by the MTDRAM driver. If the MTDRAM driver is built
+ as a module, it is also possible to specify this as a parameter when
+ loading the module.
+
+SRAM absolute position
+CONFIG_MTDRAM_ABS_POS
+ If you have system RAM accessible by the CPU but not used by Linux
+ in normal operation, you can give the physical address at which the
+ available RAM starts, and the MTDRAM driver will use it instead of
+ allocating space from Linux's available memory. Otherwise, leave
+ this set to zero. Most people will want to leave this as zero.
+
+Flash chip mapping on the Flaga Digital Module
+CONFIG_MTD_CFI_FLAGADM
