* [MTD] support driver model updatesDavid Brownell2009-04-04
| | | | | | | | | | | | Follow-on patch to the previous driver model patch for the MTD framework. This one makes various MTD drivers connect to the driver model tree, so /sys/devices/virtual/mtd/* nodes are no longer present ... mostly drivers used on boards I have handy. Based on a patch from Kay Sievers. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
* [MTD] driver model updates (part 2)Kevin Cernekee2009-04-04
| | | | | | | | | | | | | | 1) Add more sysfs attributes: flags, size, erasesize, writesize, oobsize, numeraseregions, name 2) Move core_initcall() code into init_mtd(). The original approach does not work if CONFIG_MTD=m . 3) Add device_unregister() in del_mtd_device() so that devices get removed from sysfs as each driver is unloaded.

* [MTD] driver model updatesDavid Brownell2009-04-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | Update driver model support in the MTD framework, so it fits better into the current udev-based hotplug framework: - Each mtd_info now has a device node. MTD drivers should set the dev.parent field to point to the physical device, before setting up partitions or otherwise declaring MTDs. - Those device nodes always map to /sys/class/mtdX device nodes, which no longer depend on MTD_CHARDEV. - Those mtdX sysfs nodes have a "starter set" of attributes; it's not yet sufficient to replace /proc/mtd. - Enabling MTD_CHARDEV provides /sys/class/mtdXro/ nodes and the /sys/class/mtd*/dev attributes (for udev, mdev, etc). - Include a MODULE_ALIAS_CHARDEV_MAJOR macro. It'll work with udev creating the /dev/mtd* nodes, not just a static rootfs. So the sysfs structure is pretty much what you'd expect, except that readonly chardev nodes are a bit quirky.

* [MTD] [NAND] move gen_nand's probe function to .devinit.textUwe Kleine-König2009-04-03
| | | | | | | | | | | | | | | | | | | | | | A pointer to plat_nand_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.

| | | | | | | | | | | | | | | | | | | Add support for direct mapping through mtdconcat, if possible, by attaching the samebacking_dev_info structure to the master. It has some restrictions: (1) It won't permit direct mapping of concatenated devices that have differing BDIs. (2) It doesn't support maps that span the 'gap' between devices, although it possibly could if the devices spanned across return compatible (ie. contiguous) addresses from their get_unmapped_area() ops.

* [MTD] mtdoops: allow MTD selection by nameAdrian Hunter2009-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | MTD's have both an index number and a name. Formerly, the MTD selected for mtdoops was done only by index number. With this patch, a name can be used instead. For example, the kernel command line: console=ttyMTD5 selects MTD 5 for mtdoops. But now this is also possible: console=ttyMTD,log which selects the MTD named "log" for mtdoops. This has the advantage that partitions can be added or removed that would affect the MTD index number but not the name, without having to then change the kernel command line.

* [MTD] [NAND] davinci_nand driverDavid Brownell2009-03-20
| | | | | | | | | | | | | | | | | | | | | This is a device driver for the NAND flash controller found on the various DaVinci family chips. It handles up to four SoC chipselects, and some flavors of secondary chipselect (e.g. based on upper bits of the address bus) as used with some multichip packages. (Including the 2 GiB chips used on some TI devel boards.) The 1-bit ECC hardware is supported (3 bytes ECC per 512 bytes data); but not yet the newer 4-bit ECC (10 bytes ECC per 512 bytes data), as available on chips like the DM355 or OMAP-L137 and needed with the more error-prone MLC NAND chips. This is a cleaned-up version of code that's been in use for several years now; sanity checked with the new drivers/mtd/tests.

* [MTD] [NAND] fix "raw" reads with ECC syndrome layoutsDavid Brownell2009-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | The syndrome based page read/write routines store ECC, and possibly other "OOB" data, right after each chunk of ECC'd data. With ECC chunk size of 512 bytes and a large page (2KiB) NAND, the layout is: data-0 OOB-0 data-1 OOB-1 data-2 OOB-2 data-3 OOB-3 OOB-leftover Where OOBx is (prepad, ECC, postpad). However, the current "raw" routines use a traditional layout -- data OOB, disregarding the prepad and postpad values -- so when they're used with that type of ECC hardware, those calls mix up the data and OOB. Which means, in particular, that bad block tables won't be found on startup, with data corruption and related chaos ensuing. The current syndrome-based drivers in mainline all seem to use one chunk per page; presumably they haven't noticed such bugs. Fix this, by adding read/write page_raw_syndrome() routines as siblings of the existing non-raw routines; "raw" just means to bypass the ECC computations, not change data and OOB layout.
