| | * UBI: do not warn unnecessarilyArtem Bityutskiy2010-08-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, when UBI attaches an MTD device and cannot reserve all 1% (by default) of PEBs for bad eraseblocks handling, it prints a warning. However, Matthew L. Creech <mlcreech@gmail.com> is not very happy to see this warning, because he did reserve enough of PEB at the beginning, but with time some PEBs became bad. The warning is not necessary in this case. This patch makes UBI print the warning o if this is a new image o of this is used image and the amount of reserved PEBs is only 10% (or less) of the size of the reserved PEB pool.

| | * UBI: improve delete-compatible volumes handlingBrijesh Singh2010-06-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a delete-compatible volume is found, it is first added to the 'corr' list, which contains "corrupted" PEBs which should be erased, and then it is added to the used volumes tree. However, the second step should not be done. This does not cause problems in practice, because we never access delete-compattible volumes, but it is still not the right thing to do.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ECC errors are quite typical errors on NAND, so it is worth improving the UBI message and print something like ubi_io_read: error -74 (ECC error) while reading 4096 bytes from PEB 1:4 ... rather than ubi_io_read: error -74 while reading 4096 bytes from PEB 1:4 ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch improves the way UBI handles corrupted flash, or flash containing garbage or non-UBI data, which is the same from UBI POW. Namely, we do the following: * if 5% or more PEBs are corrupted, refuse the flash * if less than 5% PEBs are corrupted, do not refuse the flash and format these PEBs * if less than 8 PEBs are corrupted, format them silently, otherwise print a warning message.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is just a preparation patch which introduces several 'struct ubi_scan_info' fields which count eraseblocks of different types.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces the %UBI_IO_BAD_HDR_READ return code for the I/O level function. We will use this code in order to distinguish between "corrupted header possibly because this is non-ubi data" and "corrupted header possibly because of real data corruption and ECC error".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We do not really need 2 separate error codes for indicating bad VID and bad EC headers (UBI_IO_BAD_EC_HDR, UBI_IO_BAD_VID_HDR), it is enough to have only one UBI_IO_BAD_HDR return code.

As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion.

His original comments follow: This patch adds support for some MLC NAND flashes that place the BB marker in the LAST page of the bad block rather than the FIRST page used for SLC NAND and other types of MLC nand. Lifted from Samsung datasheet for K9LG8G08U0A (1Gbyte MLC NAND): " Identifying Initial Invalid Block(s) All device locations are erased(FFh) except locations where the initial invalid block(s) information is written prior to shipping. The initial invalid block(s) status is defined by the 1st byte in the spare area. Samsung makes sure that the last page of every initial invalid block has non-FFh data at the column address of 2,048. ... " As far as I can tell, this is the same for all Samsung MLC nand, and in fact the samsung bsp for the processor used in our project (s3c6410) actually contained a hack similar to this patch but less portable to enable use of their NAND parts. I discovered this problem when trying to use a Micron NAND which does not used this layout - I wish samsung would put their stuff in main-line to avoid this type of problem. Currently this patch causes all MLC nand with manufacturer codes from Samsung and ST(Numonyx) to use this alternative location, since these are the manufactures that I know of that use this layout.

For instance: Samsung K9GAG08U0M (5-byte sequence): ec d5 14 b6 74 4th byte, bits 1:0 encode the page size: 0=1KiB, 1=2KiB, 2=4KiB, 3=8KiB 4th byte, bits 5:4 encode the block size: 0=64KiB, 1=128KiB, ... 4th byte, bit 6 encodes the OOB size: 0=8B/512B, 1=16B/512B Samsung K9GAG08U0D (6-byte sequence): ec d5 94 29 34 41 4th byte, bits 1:0 encode the page size: 0=2KiB, 1=4KiB, 3=8KiB, 4=rsvd 4th byte, bits 7;5:4 encode the block size: 0=128KiB, 1=256KiB, ... 4th byte, bits 6;3:2 encode the OOB size: 1=128B/page, 2=218B/page This patch uses the new 6-byte scheme if the following conditions are all true: 1) The ID code wraps around after exactly 6 bytes 2) Manufacturer is Samsung 3) 6th byte is zero The patch also extends the maximum OOB size from 128B to 256B.
