The write buffer comes from user and should be const.
Constify write buffer in mtd core and across all _write_user_prot_reg()
users. cfi_cmdset_{0001, 0002} and onenand_base will pay the cost of an
explicit cast to discard the const qualifier since the beginning, since
they are using an otp_op_t function prototype that is used for both reads
and writes. mtd_dataflash and SPI NOR will benefit of the const buffer
because they are using different paths for writes and reads.

Permit the user to specify the erase page size as a parameter.
This solves two problems:
- phram can access images made by mkfs.jffs2. mkfs.jffs2 won't
create images with erase sizes less than 8KiB; many architectures
define PAGE_SIZE as 4KiB.
- Allows more effective use of small capacity devices. JFFS2
needs somewhere between 2 and 5 empty pages for garbage collection;
and for an NVRAM part with only 32KiB of space, a smaller erase page
allows much better utilization in applications where garbage collection
is important.

It seems that several hardware ECC engine use a swapped representation
of bytes compared to software. This might having to do with how the
ECC engine is wired to the NAND controller or the order the bits are
passed to the hardware BCH logic.
This means that when the software BCH engine is working in conjunction
with data generated with hardware, sometimes we might need to swap the
bits inside bytes, eg:
0x0A = b0000_1010 -> b0101_0000 = 0x50
Make it possible by adding a boolean to the BCH initialization routine.
Regarding the implementation itself, this is a rather simple approach
that can probably be enhanced in the future by preparing the
->a_{mod,pow}_tab tables with the swapping in mind.

Any write with either dd or flashcp to a device driven by the
spear_smi.c driver will pass through the spear_smi_cpy_toio()
function. This function will get called for chunks of up to 256 bytes.
If the amount of data is smaller, we may have a problem if the data
length is not 4-byte aligned. In this situation, the kernel panics
during the memcpy:
# dd if=/dev/urandom bs=1001 count=1 of=/dev/mtd6
spear_smi_cpy_toio [620] dest c9070000, src c7be8800, len 256
spear_smi_cpy_toio [620] dest c9070100, src c7be8900, len 256
spear_smi_cpy_toio [620] dest c9070200, src c7be8a00, len 256
spear_smi_cpy_toio [620] dest c9070300, src c7be8b00, len 233
Unhandled fault: external abort on non-linefetch (0x808) at 0xc90703e8
[...]
PC is at memcpy+0xcc/0x330
The above error occurs because the implementation of memcpy_toio()
tries to optimize the number of I/O by writing 4 bytes at a time as
much as possible, until there are less than 4 bytes left and then
switches to word or byte writes.
Unfortunately, the specification states about the Write Burst mode:
"the next AHB Write request should point to the next
incremented address and should have the same size (byte,
half-word or word)"
This means ARM architecture implementation of memcpy_toio() cannot
reliably be used blindly here. Workaround this situation by update the
write path to stick to byte access when the burst length is not
multiple of 4.

The m25p80 driver is actually a generic wrapper around the spi-mem
layer. Not only the driver name is misleading, but we'd expect such a
common logic to be directly available in the core. Another reason for
moving this code is that SPI NOR controller drivers should
progressively be replaced by SPI controller drivers implementing the
spi_mem_ops interface, and when the conversion is done, we should have
a single spi-nor driver directly interfacing with the spi-mem layer.
While moving the code we also fix a longstanding issue when
non-DMA-able buffers are passed by the MTD layer.

some use their own peculiar logic to split sections.
Convert everything to ReST without affecting too much
the author's style and avoiding adding uneeded markups.
The conversion is actually:
- add blank lines and identation in order to identify paragraphs;
- fix tables markups;
- add some lists markups;
- mark literal blocks;
- adjust title markups.
At its new index.rst, let's add a :orphan: while this is not linked to

Pull Devicetree updates from Rob Herring:
"The biggest highlight here is the start of using json-schema for DT
bindings. Being able to validate bindings has been discussed for years
with little progress.
- Initial support for DT bindings using json-schema language. This is
the start of converting DT bindings from free-form text to a
structured format.
- Reworking of initrd address initialization. This moves to using the
phys address instead of virt addr in the DT parsing code. This
rework was motivated by CONFIG_DEV_BLK_INITRD causing unnecessary
rebuilding of lots of files.
- Fix stale phandle entries in phandle cache
- DT overlay validation improvements. This exposed several memory
leak bugs which have been fixed.
- Use node name and device_type helper functions in DT code
- Last remaining conversions to using %pOFn printk specifier instead
of device_node.name directly
- Create new common RTC binding doc and move all trivial RTC devices
out of trivial-devices.txt.
- New bindings for Freescale MAG3110 magnetometer, Cadence Sierra
PHY, and Xen shared memory
