Hi All,
While attempting to add support for some of the more recent NAND devices, I
ended up refactoring nand_get_flash_type() code. The refactoring was primarily
aimed at simplifying the way in which the growing number 'READID' decoding
exceptions could be accommodated.
The refactored code was tested on the data found at
http://www.linux-mtd.infradead.org/nand-data/nanddata.html, with a few extra
devices added along the way (179 devices in total).
I thought I would share the results here, partly for anyone else who might be
interested, but also to judge whether it would be worth me porting the code for
inclusion in mtd-2.6 (I currently work on a 2.6.32 derived tree!).
The results are attached as a CSV file, with a few selected results included
in-line below.
Notes:
[1] The table presents the results from 3 versions of nand_get_flash_type():
'mtd-2.6' - from the Linux-MTD git tree
'l2-mtd-2.6' - from Artem's 'MTD ML' git tree
'devel-mtd' - my development code
[2] Devices listed in table as "ONFI-only" were not tested
[3] Toshiba devices were not tested, since the datasheets only include the
decode table, not the actual READID signatures.
[4] The results assume "NAND_SCAN_BYTE1AND6" is valid and correct (affecting
ST/Numonyx LP NAND devices). (See previous emails on this topic!)
[5] "don't care" READID bytes are treated as 0xff, since this provides the best
indication of when the data is relied upon incorrectly. This is perhaps a bit
unfair to the existing code, since often the devices will output 0x00 for "don't
care" bytes, which causes far fewer errors in practice.
Sample results:

Well, mostly to avoid criticism of it not being based on the mtd-2.6 tree :-) I
have attached the file 'nand_id_decode.c' which includes most of the relevant
code. If there is interest, I am happy to port to mtd-2.6, but testing on this
version would be limited to compilation and nandsim.
Cheers,
Angus

/*
* drivers/mtd/nand/nand_id_decode.c
*
* Determine NAND device properties by decoding the READID string
*
* The following code attempts to encapsulate the knowledge in
* mtd-2.6(2011-07-09):nand_base.c:nand_get_flash_type(), refactored according
* to three basic schemes:
*
* 'ID 2' : extract properties from device table. For 2-byte IDs,
* or where device ID gives a non-zero page-size
* (SP devices).
*
* 'Extended ID': decode properties from ID string where possible, falling
* back to device table. For 3/4/5-byte IDs.
*
* 'ID 6' : decode properties from ID string where possible, falling
* back to device table. For 6-byte IDs.
*
* The refactoring is primarily aimed at simplifying the way in which decoding
* exceptions (growing fast!) can be accomodated.
*
* Tested on all devices found in
* http://www.linux-mtd.infradead.org/nand-data/nanddata.html (2011-07-09),
* EXCLUDING the following:
*
* - 'ONFI-only': READID is insufficient to decode all properties.
*
* - Toshiba devices: datasheets only present decode table, not actual
* READID strings.

That's unavoidable - please, base it on the l2-mtd-2.6.git tree:
git://git.infradead.org/users/dedekind/l2-mtd-2.6.git
:-)

The situation in MTD is that this is a scarcely populated subsystem
(everyone moves to eMMC) and we have little people who have time to take
your job, transform it into a nice patch, etc.
Your contribution is very appreciated, but please, do one more step -
create a nice patch against l2-mtd-2.6.git, with nice commit message,
and send it to this mailing list and CC Brian Norris. We will look at it
and take it to upstream.
Thanks!

I am currently grappling with this issue with my driver for the diskonchip G4,
which is an MLC nand under the hood, but has a proprietary controller around it
which doesn't interact as a "typical" NAND device. Specific to this topic, it
doesn't respond to NAND_READID commands. My solution was to skip the call to
nand_scan_ident(), which calls nand_get_flash_type(). Instead, I do all the
initializations done by nand_get_flash_type() within my driver.
Any thoughts or suggestions appreciated.
Thanks,
Mike

I am not familiar with the diskonchip technology but I had a quick look through
the patch you posted a few days ago. What you have done regarding
nand_scan_ident() is probably the most sensible solution here - I believe it was
this kind of use-case that led to nand_scan() being split into nand_scan_ident()
and nand_scan_tail().
An alternative approach would be to fake support for NAND_CMD_READID, similar to
what you have done for NAND_CMD_STATUS, with subsequent calls to
chip->read_byte() returning the 'DOCG4_IDREG' sequence {0x04, 0x00, 0xfb, 0xff}.
In the same way ONFI devices are handled, you could then add a special case in
nand_get_flash_type(), say nand_flash_detect_docg4(), jumping to 'ident_done' if
successful.
To be honest, in this case, I don't think there is much to be gained by adding
'nand_flash_detect_docg4()' to the generic code. It would just return some
hard-coded parameters to serve a single device and driver; you may as well put
them in the driver itself, as you have done. On the other hand, if you extend
it to also handle the other diskonchip varients, that might be more interesting.
Cheers,
Angus

My guess as well. The only problem is that, oddly, nand_scan_ident() calls
nand_set_defaults(). So by skipping the cal to nand_scan_ident(), the various
defaut nand methods are not set. Fortunately, I need to override most of them
anyway, but I did need to duplicate a couple trivial ones in my driver, since
they're not exported from nand_base.c

I did it this way originally. But this method requires serving up an arbitrary
unused ID and patching nand_ids.c with a new entry for the arbitrary ID
containing the docg4 parameters. It was so ugly, I went with the alternate method.

Thaks for the suggestion. Something to keep in mind; Robert Jarzmik is working
on a driver for the diskonchip G3 (which may also support the P3).
Thanks again,
