The patch fixes a bug when converting dev to mtd_info by using the drvdata of the dev, the previous code used container_of(dev, struct mtd_info, dev), but won't work for the mtdXro devices as they created without being contained inside mtd_info structure.

Add optional callback to allow platform to initialize partitions. Static partitions on a nand device could vary depending on the size of the device. This patch allows an optional platform callback to be used to setup this partition information at runtime. Scan order is: 1) chip.part_probe_types 2) chip.set_parts 3) chip.partitions 4) full mtd device (fallback for no partitions) Some of the existing nand drivers could possibly be replaced by the plat_nand driver by using this patch. These include autcpu12.c and ts7250.c drivers.

UBI volume notifications are intended to create the API to get clients notified about volume creation/deletion, renaming and re-sizing. A client can subscribe to these notifications using 'ubi_volume_register()' and cancel the subscription using 'ubi_volume_unregister()'. When UBI volumes change, a blocking notifier is called. Clients also can request "added" events on all volumes that existed before client subscribed to the notifications. If we use notifications instead of calling functions like 'ubi_gluebi_xxx()', we can make the MTD emulation layer to be more flexible: build it as a separate module and load/unload it on demand.

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 internal API presently uses 32-bit values to represent device size. This patch updates them to 64-bits but leaves the external API unchanged. Extending the external API is a separate issue for several reasons. First, no one needs it at the moment. Secondly, whether the implementation is done with IOCTLs, sysfs or both is still debated. Thirdly external API changes require the internal API to be accepted first. Note that although the MTD API will be able to support 64-bit device sizes, existing drivers do not and are not required to do so, although NAND base has been updated. In general, changing from 32-bit to 64-bit values cause little or no changes to the majority of the code with the following exceptions: - printk message formats - division and modulus of 64-bit values - NAND base support - 32-bit local variables used by mtdpart and mtdconcat - naughtily assuming one structure maps to another in MEMERASE ioctl Signed-off-by: NAdrian Hunter <ext-adrian.hunter@nokia.com> Signed-off-by: NArtem Bityutskiy <Artem.Bityutskiy@nokia.com> Signed-off-by: NDavid Woodhouse <David.Woodhouse@intel.com>

For "unlock" cycles to 16bit devices in 8bit compatibility mode we need to use the byte addresses 0xaaa and 0x555. These effectively match the word address 0x555 and 0x2aa, except the latter has its low bit set. Most chips don't care about the value of the 'A-1' pin in x8 mode, but some -- like the ST M29W320D -- do. So we need to be careful to set it where appropriate. cfi_send_gen_cmd is only ever passed addresses where the low byte is 0x00, 0x55 or 0xaa. Of those, only addresses ending 0xaa are affected by this patch, by masking in the extra low bit when the device is known to be in compatibility mode. [dwmw2: Do it only when (cmd_ofs & 0xff) == 0xaa] v4: Fix stupid typo in cfi_build_cmd_addr that failed to compile I'm writing this patch way to late at night. v3: Bring all of the work back into cfi_build_cmd_addr including calling of map_bankwidth(map) and cfi_interleave(cfi) So every caller doesn't need to. v2: Only modified the address if we our device_type is larger than our bus width.

Timeouts are currently given by the typical operation time times 8. It works in the general well-behaved case but not when an erase block is failing. For erase operations, it seems that a failing erase block will keep the device state machine in erasing state until the vendor specified maximum timeout period has passed. By this time the driver would have long since timed out, left erasing state and attempted further operations which all fail. This patch implements timeouts using values from the CFI Query structure when available. The patch also sets a longer timeout for locking operations. The current value used for locking/unlocking given by 1000000/HZ microseconds is too short for devices like J3 and J5 Strataflash which have a typical clear lock-bits time of 0.5 seconds.

There are some CFI chips which require non standard procedures to get into QRY mode. The possible way to support them would be trying different modes till QRY will be read. This patch introduce two new functions qry_mode_on qry_mode_off. qry_mode_on tries different commands in order switch chip into QRY mode. So if we have one more "odd" chip - we just could add several lines to qry_mode_on. Also using these functions remove unnecessary code duplicaton in porbe procedure. Currently there are two "odd" cases 1. Some old intel chips which require 0xFF before 0x98 2. ST M29DW chip which requires 0x98 to be sent at 0x555 (according to CFI should be 0x55) This patch is partialy based on the patch from Uwe (see "[PATCH 2/4] [RFC][MTD] cfi_probe: remove Intel chip workaround" thread ) Signed-off-by: NAlexey Korolev <akorolev@infradead.org> Signed-off-by: NAlexander Belyakov <abelyako@gmail.com> Signed-off-by: NDavid Woodhouse <David.Woodhouse@intel.com>
