UBI has 2 RB-trees to implement PEB protection, which is too
much for simply prevent PEB from being moved for some time.
This patch implements this using lists. The benefits:
1. No need to allocate protection entry on each PEB get.
2. No need to maintain balanced trees and walk them.

This patch modifies @struct ubi_wl_entry and adds union which
contains only one element so far. This is just a preparation
for further changes which will kill the protection tree and
make UBI use a list instead.

This patch replaces some legacy OMAP GPIO calls with the "new" (not
really, any more!) calls that work on most platforms.
The calls addressed by this patch are the simple ones to get and set
values ... for code that's in mainline, including the implementations
of those calls.
Except for the declarations and definitions of those calls, all of
these changes were performed by a simple SED script. Plus, a few
"if() set() else set()" branches were merged by hand.

When a PEB is moved and a write error happens, UBI switches
to R/O mode, which is wrong, because we just copy the data
and may select a different PEB and re-try this. This patch

We cannot call 'ubi_wl_get_peb()' with @ubi->buf_mutex locked,
because 'ubi_wl_get_peb()' may force erasure, which, in turn,
may call 'torture_peb()' which also locks the @ubi->buf_mutex
and deadlocks.

The 'ubi_io_read_vid_hdr()' and 'ubi_io_read_ec_hdr()' function
have the 'verbose' argument which controls whether they should
print a warning if the VID/EC header was not found or was corrupted.
Some callers require the headers to be OK, and pass 1. Some allow
a corrupted/not present header, and pass 0.
if (UBI_IO_DEBUG)
verbose = 1;
And UBI_IO_DEBUG is 1 if CONFIG_MTD_UBI_DEBUG_MSG_BLD is true. So in
this case the warning is printed all the time. This confuses people.
Thus, do not print the messages as warnings if UBI_IO_DEBUG is true,
but print them as debugging messages instead.

As suggested by Andrew Morton, remove memzero() - it's not supported
on other architectures so use of it is a potential build breaking bug.
Since the compiler optimizes memset(x,0,n) to __memzero() perfectly
well, we don't miss out on the underlying benefits of memzero().

This fixes broken terminology added in the "m25p80.c erase enhance" patch,
which added a chip erase command but called it "block erase". There are
already two block erase commands; blocks are 4KiB or 32KiB. There's also
a sector erase (usually 64 KiB). Chip erase typically covers Megabytes.
OPCODE_BE ==> OPCODE_CHIP_ERASE
erase_block ==> erase_chip

Commit d0e8c47c58575b9131e786edb488fd029eba443e ("m25p80.c extended jedec
support") added support for extended ids but in the process managed to
break detection of all flashes.
The ext jedec id check was inserted into an if statement that lacked
braces, and it did not add the required braces. As such, the detection
routine always returns the first entry in the SPI flash list.

For "unlock" cycles to 16bit devices in 8bit compatibility mode we need
to use the byte addresses 0xaaa and 0x555. These effectively match
the word address 0x555 and 0x2aa, except the latter has its low bit set.
Most chips don't care about the value of the 'A-1' pin in x8 mode,
but some -- like the ST M29W320D -- do. So we need to be careful to
set it where appropriate.
cfi_send_gen_cmd is only ever passed addresses where the low byte
is 0x00, 0x55 or 0xaa. Of those, only addresses ending 0xaa are
affected by this patch, by masking in the extra low bit when the device
is known to be in compatibility mode.
[dwmw2: Do it only when (cmd_ofs & 0xff) == 0xaa]
v4: Fix stupid typo in cfi_build_cmd_addr that failed to compile
I'm writing this patch way to late at night.
v3: Bring all of the work back into cfi_build_cmd_addr
including calling of map_bankwidth(map) and cfi_interleave(cfi)
So every caller doesn't need to.
v2: Only modified the address if we our device_type is larger than our
bus width.

To keep the size of changesets sane we split the switch by drivers;
to keep the damn thing bisectable we do the following:
1) rename the affected methods, add ones with correct
prototypes, make (few) callers handle both. That's this changeset.
2) for each driver convert to new methods. *ALL* drivers
are converted in this series.
3) kill the old (renamed) methods.
Note that it _is_ a flagday; all in-tree drivers are converted and by the
end of this series no trace of old methods remain. The only reason why
we do that this way is to keep the damn thing bisectable and allow per-driver
debugging if anything goes wrong.
New methods:
open(bdev, mode)
release(disk, mode)
ioctl(bdev, mode, cmd, arg) /* Called without BKL */
compat_ioctl(bdev, mode, cmd, arg)
locked_ioctl(bdev, mode, cmd, arg) /* Called with BKL, legacy */
