| * | | | mtd: docg3: add fast modeRobert Jarzmik2012-01-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Docg3 chips can work in 3 modes : normal MLC mode, fast mode and reliable mode. Normally, as docg3 is a MLC chip, it should be configured to work in normal mode. In both normal mode, each page is distinct. This means that writing to page 12 of blocks 14,15 writes only to that page, and reading from page 12 of blocks 14,15 reads only from that page. In reliable and fast modes, pages are coupled by pairs, and are clones one of each other. This means that the available capacity of the chip is halved. Pages are coupled in each block, and page of index 2*n contains the same data as page 2*n+1 of the same block. In fast mode, the reads occur a bit faster, but are a bit less reliable that in normal mode. When reading from page 2*n, the chip reads bytes from both page 2*n and page 2*n+1, makes a logical and for each byte, and returns the result. As programming a page means "clearing bits", even if a bit was not cleared on one page because the flash is worn out, the other page has the bit cleared, and the result of the "AND" gives a correct result. When writing to page 2*n, the chip writes data to both page 2*n and page 2*n+1.

The BCH correction code relied upon the BCH library, where all data and ECC is bit-reversed. The BCH library works correctly when each input byte is bit-reversed, and accordingly ECC output is also bit-reversed.

This especially ensures that raw reads do not use ECC corrections, and AUTOOOB and PLACEOOB do use ECC correction. The approach is to empty docg3_read() and make it a wrapper to docg3_read_oob(). As docg3_read_oob() handles all the funny cases (no data buffer but oob buffer, data buffer but no oob buffer, ...), docg3_read() is just a special use of docg3_read_oob().

This meant that, while the error path was handled correctly on the first time through blktrans_open(), the device is erroneously considered already open on the second time through. This problem can be seen, for instance, when a UBI volume is simultaneously mounted as a UBIFS partition and read through its corresponding gluebi mtdblockX device. This results in blktrans_open() passing its error checks (with `dev->open > 0') without actually having a handle on the device.

That should lead to (basically) identical code in docprobe.c. The current two defaults should be merged. And, while we're at it, if MTD_DOCPROBE is set MTD_DOCPROBE_ADDRESS will always be set. (MTD_DOCPROBE_ADDRESS depends on MTD_DOCPROBE and it has a default value.) So the check whether CONFIG_MTD_DOCPROBE_ADDRESS is defined is unnecessary and should be dropped.

We can't make this assumption on local structs, and we shouldn't be relying on a previous state anyway. Instead, we initialize mode to 0 for don't-care situations (i.e., the operation does not use OOB anyway) and MTD_OPS_PLACE_OOB when we want to place OOB data. This fixes a bug with nand_default_block_markbad(), where we catch on the BUG() call in nand_fill_oob(): Kernel bug detected[#1]: ...

| * mtd: provide an alias for the redboot module nameAndres Salomon2011-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | parse_mtd_partitions takes a list of partition types; if the driver isn't loaded, it attempts to load it, and then it grabs the partition parser. For redboot, the module name is "redboot.ko", while the parser name is "RedBoot". Since modprobe is case-sensitive, attempting to modprobe "RedBoot" will never work. I suspect the embedded systems that make use of redboot just always manually loaded redboot prior to loading their specific nand chip drivers (or statically compiled it in).
