1dbebd3256 mtd: harmonize mtd_writev usage
This patch makes the 'mtd_writev()' function more usable and logical. We first
teach it to fall-back to the 'default_mtd_writev()' function if the MTD driver
does not define its own '->writev()' method. Then we make block2mtd and JFFS2
just 'mtd_writev()' instead of 'default_mtd_writev()' function. This means we
can now stop exporting 'default_mtd_writev()' and instead, export
'mtd_writev()'. This is much cleaner and more logical, as well as allows us to
get read of another direct 'mtd->writev' access in JFFS2.

If doc_probe_device() returned an ERR_PTR, then we accidentally saved

5d3667eee4 mtd: Remove redundant spi driver bus initialization
In ancient times it was necessary to manually initialize the bus field of an
spi_driver to spi_bus_type. These days this is done in spi_driver_register(),
so we can drop the manual assignment.

The patch was generated using the following coccinelle semantic patch:
// <smpl>

identifier _driver;

struct spi_driver _driver = {
	.driver = {
-		.bus = &spi_bus_type,

c3de8a8a5a mtd: docg3: add fast mode
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.

Credit for discovering the BCH algorith parameters, and bit
reversing algorithm is to be give to Mike Dunn and Ivan
Djelic.

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.

32a50b3a45 mtd: docg3: fix reading oob+data without correction
Fix the docg3 reads to be able to cope with all possible
data buffer / oob buffer / file mode combinations from
docg3_read_oob().
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().

6be55f79a2 mtd: clean up usage of MTD_DOCPROBE_ADDRESS
Depending on whether MTD_DOCPROBE_ADVANCED is set or not,
MTD_DOCPROBE_ADDRESS will default to either 0x0000 or 0. 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.

adaf2a5d08 mtd: sst25l don't specify default parsing options
Since 'cmdline, NULL' is now a default for parse_mtd_partitions, don't specify
this in every driver, instead pass NULL to force parse_mtd_partitions
to use default.

1c5454eed8 Change Ryan Mallon's email address across the kernel
I no longer work at Bluewater Systems. Update my email address accordingly. I
have deleted my email address from C files rather than change it. This
was suggested by several people, since the commit from my new email
address will cause scripts/get_maintainer.pl to function properly. I
have not added the .mailmap entry as suggested by Joe because I think
it is no longer necessary if I touch all the files which had my name
in them.

counterparts will soon be gone.  Replace uses with mtd_device_register()
