mtd_dataflash: fix probing of AT45DB321C chips.

2009-03-17T00:52:56+00:00

commit 229cc58ba2b5a83b0b55764c6cb98695c106238a upstream.

Commit 771999b65f79264acde4b855e5d35696eca5e80c ("[MTD] DataFlash: bugfix,
binary page sizes now handled") broke support for probing AT45DB321C flash
chips.  These chips do not support the "page size" status bit, so if we
match the JEDEC id return early.

[MTD] DataFlash: bugfix, binary page sizes now handled

2008-07-30T13:20:32+00:00

The wrong version of the "teach dataflash about binary density" patch
just got merged (v2 not v3) ... this restores the missing updates:

  * Fix the cmdlinepart *regression* that caused testing failures (!!)
    by restoring the original part labels in relevant cases.

  * Don't reference things that don't exist (!)
	- An opcode that doesn't even exist for DataFlash
	- The part is "at45db642" not "at45db641"
	- ID zero in this JEDEC table

  * Make the JEDEC probe routine report and handle errors better:
	- If the SPI calls fail, return the error codes.
	- Don't depend on ordering of table entries.
	- Unrecognized ids are different from parts that have no ID.
          We won't actually know how to handle them correctly; display
	  the ID and ignore the chip.

  * Move the original block comment about the "legacy" chip ID scheme
    back next to the code to which it applies ... not next to the new
    JEDEC query code, which uses an entirely different strategy.

  * Don't print a guessed erasesize; /proc/mtd has the real value.

And add a few more comments.

[MTD] [NAND] remove PPC hardcoded address from DiskOnChip drivers

2008-07-11T17:21:54+00:00

Such a hardcoded address can cause a checkstop or machine check if
the driver is in the kernel but the address is not acknowledged.

Both drivers allow an address to be specified as either a module
parameter or config option.   Any future powerpc board should either
use one of these methods or find the address in the device tree.

MTD/JFFS2: remove CVS keywords

2008-06-04T16:50:17+00:00

Once upon a time, the MTD repository was using CVS.

This patch therefore removes all usages of the no longer updated CVS
keywords from the MTD code.

This also includes code that printed them to the user.
