Once upon a time, the MTD repository was using CVS. This patch therefore removes all usages of the no longer updated CVS keywords from the MTD code. This also includes code that printed them to the user. Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

---help---
|
|
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 its 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.

|

Some of Ramix's PMC551 boards with 256M configurations have invalid

break other memory configurations. If unsure say N.

This option makes the PMC551 more verbose during its 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.

This is an MTD driver for the DEC's MS02-NV (54-20948-01) battery
|
|
backed-up NVRAM module. The module was originally meant as an NFS
|
|
accelerator. Say Y here if you have a DECstation 5000/2x0 or a
|
|
DECsystem 5900 equipped with such a module.
|
|
|
|
If you want to compile this driver as a module ( = code which can be

|
inserted in and removed from the running kernel whenever you want),
|

say M here and read <file:Documentation/kbuild/modules.txt>.

The module will be called ms02-nv.ko.

This enables access to most modern SPI flash chips, used for

program and data storage. Series supported include Atmel AT26DF,

Spansion S25SL, SST 25VF, ST M25P, and Winbond W25X. Other chips
|

are supported as well. See the driver source for the current list,
|
|
or to add other chips.
|
|
|
|
Note that the original DataFlash chips (AT45 series, not AT26DF),
|
|
need an entirely different driver.
|

Set up your spi devices with the right board-specific platform data,

doesn't support the JEDEC ID instruction.

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

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 <file:drivers/mtd/devices/docprobe.c> source code.
|

emulate a block device by using a kind of file system on the flash

chips.

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 <file:drivers/mtd/devices/docprobe.c>.
