2009-06-06mtd: physmap_of: Add multiple regions and concatenation supportStefan Roese
This patch adds support to handle multiple non-identical chips in one flash device tree node. It also adds concat support to physmap_of. This makes it possible to support e.g. the Intel P30 48F4400 chips which internally consists of 2 non-identical NOR chips on one die. Additionally partitions now can span over multiple chips. To describe such a chip's, multiple "reg" tuples are now supported in one flash device tree node. Here an dts example: flash@f0000000,0 { #address-cells = <1>; #size-cells = <1>; compatible = "cfi-flash"; reg = <0 0x00000000 0x02000000 0 0x02000000 0x02000000>; bank-width = <2>; partition@0 { label = "test-part1"; reg = <0 0x04000000>; }; }; Signed-off-by: Stefan Roese <sr@denx.de> Reviewed-by: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

2009-06-05mtd: uclinux: allow systems to override map addr/sizeMike Frysinger
Due to a processor anomaly (05000263 to be exact), most Blackfin parts cannot keep the embedded filesystem image directly after the kernel in RAM. Instead, the filesystem needs to be relocated to the end of memory. As such, we need to tweak the map addr/size during boot for Blackfin systems. This can be done in any early arch/board init code.

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.

2009-06-02UBI: add notification APIDmitry Pervushin
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.

2009-06-02UBI: do not switch to R/O mode on read errorsArtem Bityutskiy
This patch improves UBI errors handling. ATM UBI switches to R/O mode when the WL worker fails to read the source PEB. This means that the upper layers (e.g., UBIFS) has no chances to unmap the erroneous PEB and fix the error. This patch changes this behaviour and makes UBI put PEBs like this into a separate RB-tree, thus preventing the WL worker from hitting the same read errors again and again. But there is a 10% limit on a maximum amount of PEBs like this. If there are too much of them, UBI switches to R/O mode. Additionally, this patch teaches UBI not to panic and switch to R/O mode if after a PEB has been copied, the target LEB cannot be read back. Instead, now UBI cancels the operation and schedules the target PEB for torturing. The error paths has been tested by ingecting errors into 'ubi_eba_copy_leb()'.
