CONFIG_MTD_ARM_INTEGRATOR left for rmk.
i82092 compatible bridge support
CONFIG_I82092
This provides support for the Intel I82092AA PCI-to-PCMCIA bridge device,
found in some older laptops and more commonly in evaluation boards for the
chip.
CONFIG_JFFS_PROC_FS
Enabling this option will cause statistics from mounted JFFS file systems
to be made available to the user in the /proc/fs/jffs/ directory.
Support for absent chips in bus mapping
CONFIG_MTD_ABSENT
This option enables support for a dummy probing driver used to
allocated placeholder MTD devices on systems that have socketed
or removable media. Use of this driver as a fallback chip probe
preserves the expected registration order of MTD device nodes on
the system regardless of media presence. Device nodes created
with this driver will return -ENODEV upon access.
MTD Emulation using block device
CONFIG_MTD_BLKMTD
This driver allows a block device to appear as an MTD. It would
generally be used in the following cases:
Using Compact Flash as an MTD, these usually present themselves to
the system as an ATA drive.
Testing MTD users (eg JFFS2) on large media and media that might
be removed during a write (using the floppy drive).
Cirrus CDB89712 evaluation board mappings
CONFIG_MTD_CDB89712
This enables access to the flash or ROM chips on the CDB89712 board.
If you have such a board, say 'Y'.
Detect non-CFI AMD/JEDEC-compatible flash chips
CONFIG_MTD_JEDECPROBE
This option enables JEDEC-style probing of flash chips which are not
compatible with the Common Flash Interface, but will use the common
CFI-targetted flash drivers for any chips which are identified which
are in fact compatible in all but the probe method. This actually
covers most AMD/Fujitsu-compatible chips, and will shortly cover also
non-CFI Intel chips (that code is in MTD CVS and should shortly be sent
for inclusion in Linus' tree)
BIOS flash chip on Intel L440GX boards
CONFIG_MTD_L440GX
Support for treating the BIOS flash chip on Intel L440GX motherboards
as an MTD device - with this you can reprogram your BIOS.
BE VERY CAREFUL.
28F160xx flash driver for LART
CONFIG_MTD_LART
This enables the flash driver for LART. Please note that you do
not need any mapping/chip driver for LART. This one does it all
for you, so go disable all of those if you enabled some of them (:
Older (theoretically obsoleted now) drivers for non-CFI chips
CONFIG_MTD_OBSOLETE_CHIPS
This option does not enable any code directly, but will allow you to
select some other chip drivers which are now considered obsolete,
because the generic CONFIG_JEDEC_PROBE code above should now detect
the chips which are supported by these drivers, and allow the generic
CFI-compatible drivers to drive the chips. Say 'N' here unless you have
already tried the CONFIG_JEDEC_PROBE method and reported its failure
to the MTD mailing list at <linux-mtd@lists.infradead.org>
CFI Flash device mapped on Hitachi SolutionEngine
CONFIG_MTD_SOLUTIONENGINE
This enables access to the flash chips on the Hitachi SolutionEngine and
similar boards. Say 'Y' if you are building a kernel for such a board.
Flash chip mapping on TQM8xxL PPC board
CONFIG_MTD_TQM8XXL
The TQM8xxL PowerPC board has up to two banks of CFI-compliant
chips, currently uses AMD one. This 'mapping' driver supports
that arrangement, allowing the CFI probe and command set driver
code to communicate with the chips on the TQM8xxL board. More at
(http://www.denx.de/embedded-ppc-en.html).
Darkness
CONFIG_MEMORY_SET
This is an option about which you will never be asked a question.
Therefore, I conclude that you do not exist - go away.
Are you still here? Piss off, I tell you.
There is a grue here.
Physical memory size
CONFIG_MEMORY_SIZE
This sets the default memory size assumed by your SH kernel. It can
be overridden as normal by the 'mem=' argument on the kernel command
line. If unsure, consult your board specifications or just leave it
as 0x00400000 which was the default value before this became
configurable.
CONFIG_SH_PCIDMA_NONCOHERENT
Enable this option if your platform does not have a CPU cache which
remains coherent with PCI DMA. It is safest to say 'Y', although you
will see better performance if you can say 'N', because the PCI DMA
code will not have to flush the CPU's caches. If you have a PCI host
bridge integrated with your SH CPU, refer carefully to the chip specs
to see if you can say 'N' here. Otherwise, leave it as 'Y'.
