For this driver, there is nothing between nand_scan_ident() and
nand_scan_tail(). They can be merged into nand_scan().
Also, nand_scan() returns an appropriate error value when it fails.
Use it instead of the fixed error code -ENXIO.

Commit e96a8a3bb671 ("UBI: Fastmap: Do not add vol if it already
exists") introduced a bug by changing the possible error codes returned
by add_vol():
- this function no longer returns NULL in case of allocation failure
but return ERR_PTR(-ENOMEM)
- when a duplicate entry in the volume RB tree is found it returns
ERR_PTR(-EEXIST) instead of ERR_PTR(-EINVAL)
Fix the tests done on add_vol() return val to match this new behavior.

When building with -Wmaybe-uninitialized, gcc produces a silly false positive
warning for the mtk_ecc_encode function:
drivers/mtd/nand/mtk_ecc.c: In function 'mtk_ecc_encode':
drivers/mtd/nand/mtk_ecc.c:402:15: error: 'val' may be used uninitialized in this function [-Werror=maybe-uninitialized]
The function for some reason contains a double byte swap on big-endian
builds to get the OOB data into the correct order again, and is written
in a slightly confusing way.
Using a simple memcpy32_fromio() to read the data simplifies it a lot
so it becomes more readable and produces no warning. However, the
output might not have 32-bit alignment, so we have to use another
memcpy to avoid taking alignment faults or writing beyond the end
of the array.

When changing from one data interface setting to another, one has to
ensure a specific sequence which is described in the ONFI spec.
One of these constraints is that the CE line has go high after a reset
before a command can be sent with the new data interface setting, which
is not guaranteed by the current implementation.
Rework the nand_reset() function and all the call sites to make sure the
CE line is asserted and released when required.
Also make sure to actually apply the new data interface setting on the
first die.

Pull ARM SoC cleanups from Arnd Bergmann:
"The cleanups for v4.9 are a little larger that usual, but thankfully
that is almost exclusively due to removing a significant number of
files that have become obsolete after the still ongoing conversion of
old board files to devicetree.
- for mach-omap2, which is still the largest platform in arch/arm/,
the conversion to DT is finally complete after the Nokia N900 is
now fully supported there, along with the omap3 LDP, and we can
remove those two board files. If no regressions are found, another
large cleanup for the platform will happen as a follow-up, removing
dead code and restructuring the platform based on being DT-only.
- In mach-imx, similar work is ongoing, but has not come that far.
This time, we remove the obsolete board file for the i.MX1
generation, which like i.MX25, i.MX5, i.MX6, and i.MX7 is now
DT-only. The remaining board files are for i.MX2 and i.MX3 machines
based on old ARM926 or ARM1136 cores that should work with DT in
principle.
- realview has just been converted from board files to DT, and a lot
of code gets removed in the process. This is the last
ARM/Keil/Versatile derived platform that was still using board
files, the other ones being integrator, versatile and vexpress. We
can probably merge the remaining code into a single directory in
the near future.
- clps711x had completed the conversion in v4.8, but we accidentally
left the files in place that should have been deleted then"

Introduced by commit fde85cfd2d07 ("mtd: nand: Fix nand_command_lp() for
8bits opcodes") and I didn't have the heart to have Boris rewrite his
pull request just for that. Anyway, there's some value in having stable
commit hashes.

Notable core changes:
- add the infrastructure to automate NAND timings configuration
- provide a generic DT property to maximize ECC strength
The rest is just a bunch of minor drivers and core fixes/cleanup
patches.
"
Also not noted: some refactoring in the core bad block table handling,
to help with improving some of the logic in error cases.
