6 tristate "Ramix PMC551 PCI Mezzanine RAM card support"
9 This provides a MTD device driver for the Ramix PMC551 RAM PCI card
10 from Ramix Inc. <http://www.ramix.com/products/memory/pmc551.html>.
11 These devices come in memory configurations from 32M - 1G. If you
12 have one, you probably want to enable this.
14 If this driver is compiled as a module you get the ability to select
15 the size of the aperture window pointing into the devices memory.
16 What this means is that if you have a 1G card, normally the kernel
17 will use a 1G memory map as its view of the device. As a module,
18 you can select a 1M window into the memory and the driver will
19 "slide" the window around the PMC551's memory. This was
20 particularly useful on the 2.2 kernels on PPC architectures as there
21 was limited kernel space to deal with.
23 config MTD_PMC551_BUGFIX
24 bool "PMC551 256M DRAM Bugfix"
27 Some of Ramix's PMC551 boards with 256M configurations have invalid
28 column and row mux values. This option will fix them, but will
29 break other memory configurations. If unsure say N.
31 config MTD_PMC551_DEBUG
32 bool "PMC551 Debugging"
35 This option makes the PMC551 more verbose during its operation and
36 is only really useful if you are developing on this driver or
37 suspect a possible hardware or driver bug. If unsure say N.
40 tristate "DEC MS02-NV NVRAM module support"
41 depends on MACH_DECSTATION
43 This is an MTD driver for the DEC's MS02-NV (54-20948-01) battery
44 backed-up NVRAM module. The module was originally meant as an NFS
45 accelerator. Say Y here if you have a DECstation 5000/2x0 or a
46 DECsystem 5900 equipped with such a module.
48 If you want to compile this driver as a module ( = code which can be
49 inserted in and removed from the running kernel whenever you want),
50 say M here and read <file:Documentation/kbuild/modules.txt>.
51 The module will be called ms02-nv.
54 tristate "Support for AT45xxx DataFlash"
57 This enables access to AT45xxx DataFlash chips, using SPI.
58 Sometimes DataFlash chips are packaged inside MMC-format
59 cards; at this writing, the MMC stack won't handle those.
61 config MTD_DATAFLASH_WRITE_VERIFY
62 bool "Verify DataFlash page writes"
63 depends on MTD_DATAFLASH
65 This adds an extra check when data is written to the flash.
66 It may help if you are verifying chip setup (timings etc) on
67 your board. There is a rare possibility that even though the
68 device thinks the write was successful, a bit could have been
69 flipped accidentally due to device wear or something else.
71 config MTD_DATAFLASH_OTP
72 bool "DataFlash OTP support (Security Register)"
73 depends on MTD_DATAFLASH
75 Newer DataFlash chips (revisions C and D) support 128 bytes of
76 one-time-programmable (OTP) data. The first half may be written
77 (once) with up to 64 bytes of data, such as a serial number or
78 other key product data. The second half is programmed with a
79 unique-to-each-chip bit pattern at the factory.
82 tristate "Support most SPI Flash chips (AT26DF, M25P, W25X, ...)"
83 depends on SPI_MASTER && MTD_SPI_NOR
86 This enables access to most modern SPI flash chips, used for
87 program and data storage. Series supported include Atmel AT26DF,
88 Spansion S25SL, SST 25VF, ST M25P, and Winbond W25X. Other chips
89 are supported as well. See the driver source for the current list,
90 or to add other chips.
92 Note that the original DataFlash chips (AT45 series, not AT26DF),
93 need an entirely different driver.
95 Set up your spi devices with the right board-specific platform data,
96 if you want to specify device partitioning or to use a device which
97 doesn't support the JEDEC ID instruction.
100 tristate "Microchip 23K256 SRAM"
101 depends on SPI_MASTER
103 This enables access to Microchip 23K256 SRAM chips, using SPI.
105 Set up your spi devices with the right board-specific
106 platform data, or a device tree description if you want to
107 specify device partitioning
110 tristate "SPEAR MTD NOR Support through SMI controller"
111 depends on PLAT_SPEAR
114 This enable SNOR support on SPEAR platforms using SMI controller
117 tristate "Support SST25L (non JEDEC) SPI Flash chips"
118 depends on SPI_MASTER
120 This enables access to the non JEDEC SST25L SPI flash chips, used
121 for program and data storage.
123 Set up your spi devices with the right board-specific platform data,
124 if you want to specify device partitioning.
126 config MTD_BCM47XXSFLASH
127 tristate "Support for serial flash on BCMA bus"
128 depends on BCMA_SFLASH && (MIPS || ARM)
130 BCMA bus can have various flash memories attached, they are
131 registered by bcma as platform devices. This enables driver for
132 serial flash memories.
135 tristate "Uncached system RAM"
137 If your CPU cannot cache all of the physical memory in your machine,
138 you can still use it for storage or swap by using this driver to
139 present it to the system as a Memory Technology Device.
142 tristate "Physical system RAM"
144 This is a re-implementation of the slram driver above.
146 Use this driver to access physical memory that the kernel proper
147 doesn't have access to, memory beyond the mem=xxx limit, nvram,
148 memory on the video card, etc...
151 tristate "28F160xx flash driver for LART"
152 depends on SA1100_LART
154 This enables the flash driver for LART. Please note that you do
155 not need any mapping/chip driver for LART. This one does it all
156 for you, so go disable all of those if you enabled some of them (:
159 tristate "Test driver using RAM"
161 This enables a test MTD device driver which uses vmalloc() to
162 provide storage. You probably want to say 'N' unless you're
165 config MTDRAM_TOTAL_SIZE
166 int "MTDRAM device size in KiB"
167 depends on MTD_MTDRAM
170 This allows you to configure the total size of the MTD device
171 emulated by the MTDRAM driver. If the MTDRAM driver is built
172 as a module, it is also possible to specify this as a parameter when
175 config MTDRAM_ERASE_SIZE
176 int "MTDRAM erase block size in KiB"
177 depends on MTD_MTDRAM
180 This allows you to configure the size of the erase blocks in the
181 device emulated by the MTDRAM driver. If the MTDRAM driver is built
182 as a module, it is also possible to specify this as a parameter when
186 tristate "MTD using block device"
189 This driver allows a block device to appear as an MTD. It would
190 generally be used in the following cases:
192 Using Compact Flash as an MTD, these usually present themselves to
193 the system as an ATA drive.
194 Testing MTD users (eg JFFS2) on large media and media that might
195 be removed during a write (using the floppy drive).
197 config MTD_POWERNV_FLASH
198 tristate "powernv flash MTD driver"
199 depends on PPC_POWERNV
201 This provides an MTD device to access flash on powernv OPAL
202 platforms from Linux. This device abstracts away the
203 firmware interface for flash access.
205 comment "Disk-On-Chip Device Drivers"
208 tristate "M-Systems Disk-On-Chip G3"
210 select BCH_CONST_PARAMS if !MTD_NAND_BCH
213 This provides an MTD device driver for the M-Systems DiskOnChip
216 The driver provides access to G3 DiskOnChip, distributed by
217 M-Systems and now Sandisk. The support is very experimental,
218 and doesn't give access to any write operations.
220 config MTD_ST_SPI_FSM
221 tristate "ST Microelectronics SPI FSM Serial Flash Controller"
224 This provides an MTD device driver for the ST Microelectronics
225 SPI Fast Sequence Mode (FSM) Serial Flash Controller and support
226 for a subset of connected Serial Flash devices.
