Use menuconfig objects: MTD

Use menuconfigs instead of menus, so the whole menu can be disabled at once instead of going through all options. Signed-off-by: Jan Engelhardt Signed-off-by: Andrew Morton Signed-off-by: David Woodhouse

[MTD] Driver for AT26Fxxx dataflash devices

2007-04-17T17:42:56Z

Add support for AT26Fxxx dataflash devices. These devices have a quite different commandset than the AT45xxx chips, which are handled by at91_dataflash.c, so a combined driver turned out to be more ugly than useful. Tested only on AT26F004.

[PATCH] BLOCK: Make it possible to disable the block layer [try #6]

2006-09-30T18:52:31Z

Make it possible to disable the block layer. Not all embedded devices require it, some can make do with just JFFS2, NFS, ramfs, etc - none of which require the block layer to be present. This patch does the following: (*) Introduces CONFIG_BLOCK to disable the block layer, buffering and blockdev support. (*) Adds dependencies on CONFIG_BLOCK to any configuration item that controls an item that uses the block layer. This includes: (*) Block I/O tracing. (*) Disk partition code. (*) All filesystems that are block based, eg: Ext3, ReiserFS, ISOFS. (*) The SCSI layer. As far as I can tell, even SCSI chardevs use the block layer to do scheduling. Some drivers that use SCSI facilities - such as USB storage - end up disabled indirectly from this. (*) Various block-based device drivers, such as IDE and the old CDROM drivers. (*) MTD blockdev handling and FTL. (*) JFFS - which uses set_bdev_super(), something it could avoid doing by taking a leaf out of JFFS2's book. (*) Makes most of the contents of linux/blkdev.h, linux/buffer_head.h and linux/elevator.h contingent on CONFIG_BLOCK being set. sector_div() is, however, still used in places, and so is still available. (*) Also made contingent are the contents of linux/mpage.h, linux/genhd.h and parts of linux/fs.h. (*) Makes a number of files in fs/ contingent on CONFIG_BLOCK. (*) Makes mm/bounce.c (bounce buffering) contingent on CONFIG_BLOCK. (*) set_page_dirty() doesn't call __set_page_dirty_buffers() if CONFIG_BLOCK is not enabled. (*) fs/no-block.c is created to hold out-of-line stubs and things that are required when CONFIG_BLOCK is not set: (*) Default blockdev file operations (to give error ENODEV on opening). (*) Makes some /proc changes: (*) /proc/devices does not list any blockdevs. (*) /proc/diskstats and /proc/partitions are contingent on CONFIG_BLOCK. (*) Makes some compat ioctl handling contingent on CONFIG_BLOCK. (*) If CONFIG_BLOCK is not defined, makes sys_quotactl() return -ENODEV if given command other than Q_SYNC or if a special device is specified. (*) In init/do_mounts.c, no reference is made to the blockdev routines if CONFIG_BLOCK is not defined. This does not prohibit NFS roots or JFFS2. (*) The bdflush, ioprio_set and ioprio_get syscalls can now be absent (return error ENOSYS by way of cond_syscall if so). (*) The seclvl_bd_claim() and seclvl_bd_release() security calls do nothing if CONFIG_BLOCK is not set, since they can't then happen. Signed-Off-By: David Howells Signed-off-by: Jens Axboe

Re-add module description for ms02-nv to Kconfig

2006-05-17T15:20:37Z

In an unrelated MTD commit, a description about the ms02-nv module got removed from Kconfig. While I personally agree with this removal, the module maintainer (Maciej W. Rozycki) would like to see it added back. In the absense of any consistency regarding Kconfig descriptions his wish should be followed. Signed-off-by: Martin Michlmayr Acked-by: Maciej W.

[PATCH] Remove blkmtd

2006-04-11T13:18:43Z

Remove the blkmtd driver. - An alternative exists (block2mtd) that hasn't had bug report for > 1 year. - Most embedded people tend to use ancient kernels with custom patches from mtd cvs and elsewhere, so the 1 year warning period neither helps nor hurts them too much. - It's in the way of klibc. The problems caused by pulling blkmtd support are fairly low, while the problems caused by delaying klibc can be fairly substantial. At best, this would be a severe burden on hpa's time.

[PATCH] spi: M25 series SPI flash

2006-01-14T00:29:55Z

This was originally a driver for the ST M25P80 SPI flash. It's been updated slightly to handle other M25P series chips. For many of these chips, the specific type could be probed, but for now this just requires static setup with flash_platform_data that lists the chip type (size, format) and any default partitioning to use.

[PATCH] spi: mtd dataflash driver

2006-01-14T00:29:54Z

This is a conversion of the AT91rm9200 DataFlash MTD driver to use the lightweight SPI framework, and no longer be AT91-specific. It compiles down to less than 3KBytes on ARM. The driver allows board-specific init code to provide platform_data with the relevant MTD partitioning information, and hotplugs. This version has been lightly tested. Its parent at91_dataflash driver has been pretty well banged on, although kernel.org JFFS2 dataflash support was acting broken the last time I tried it.
