2009-06-05mtd: Flex-OneNAND supportRohit Hagargundgi
Add support for Samsung Flex-OneNAND devices. Flex-OneNAND combines SLC and MLC technologies into a single device. SLC area provides increased reliability and speed, suitable for storing code such as bootloader, kernel and root file system. MLC area provides high density and is suitable for storing user data. SLC and MLC regions can be configured through kernel parameter.

2009-06-05mtd: uclinux: do not allow to be built as a moduleMike Frysinger
There isn't any benefit to building the uClinux MTD map as a module as the rootfs it requires in order to actually be usable is appended to the kernel image, not the module. No known system builds it this way either, so change the option to "bool".

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.

2009-06-05mtd: plat_nand: allow platform to set partitionsH Hartley Sweeten
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.

2009-06-05mtd: remove pmcmsp-ramroot.cShane McDonald
The RAMROOT function was a successful but non-portable attempt to append the root filesystem to the end of the kernel image. The preferred and portable solution is to use an initramfs instead. The only user of this function was the msp71xx configuration in the MIPS architecture; as the use of the RAMROOT has been removed from that configuration, there are no more users, so this code can be removed.

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()'.
