Due to grown code sizes the TQM85xx boards don't build any more with
some older tool chains (like ELDK 4.2). As these boards have long
reached EOL it seems a waste of effort trying to fix them. The vendor
has agreed to drop support for them, too. So let's get rid of them.

commit 14f44abf1dafc20ba42ce8616a8fc8fbd1b3712b

mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driver
The NAND_CHIPOPTIONS_MSK has limited utility and is causing real bugs. It
silently masks off at least one flag that might be set by the driver
(NAND_NO_SUBPAGE_WRITE). This breaks the GPMI NAND driver and possibly
others.
Really, as long as driver writers exercise a small amount of care with
NAND_* options, this mask is not necessary at all; it was only here to
prevent certain options from accidentally being set by the driver. But the
original thought turns out to be a bad idea occasionally. Thus, kill it.
Note, this patch fixes some major gpmi-nand breakage.

Micron NAND flash (e.g. MT29F4G08ABADAH4) BLOCK LOCK READ STATUS is not
the same as others. Instead of bit 1 being lock, it is #lock_tight.
To make the driver support either format, ignore bit 1 and use only
bit 0 and bit 2.

With onfi a flash is organized into one or more logical units (LUNs).
A logical unit (LUN) is the minimum unit that can independently execute
commands and report status.
Mtd does not exploit LUN, so make it see a big single flash where size is
lun_size * number_of_lun.
Without this patch MT29F8G08ADBDAH4 size is 512MiB instead of 1GiB.

The Programmable Multibit ECC (PMECC) controller is a programmable binary
BCH(Bose, Chaudhuri and Hocquenghem) encoder and decoder. This controller
can be used to support both SLC and MLC NAND Flash devices. It supports to
generate ECC to correct 2, 4, 8, 12 or 24 bits of error per sector of data.
To use PMECC in this driver, the user needs to set the PMECC correction
capability, the sector size and ROM lookup table offsets in board config file.
This driver is ported from Linux kernel atmel_nand PMECC patch. The main difference
is in this version it uses registers structure access hardware instead of using macros.
It is tested in 9x5 serial boards.

"For the beagleboard, ecc.size is not explicitly set when doing 'nandecc
sw'. If it's not set for the NAND_ECC_SOFT case in nand_scan_tail, it's
set to 256 bytes.
When doing 'nandecc hw', ecc.size is set to 512 bytes. Hence, when
changing back to 'nandecc sw' ecc.size remains at 512 bytes and suddenly
the format has changed."
No patch has been submitted and the issue was still present. This patch
adds the mentioned solution. Tested on a tam3517 board.

commit 54652991
Work around bug in Numonyx P33/P30 256-Mbit 65nm flash chips
fixes a problem for Numonyx P33/P30 flashes for 256-Mbit, but this leads
to problems for smaller versions of this chip e.g. the 32Mbit version
with deviceid 0x16 on mgcoge. So move the code for this work around to
an own function and check previously manufacturer id and device id to
not break other flashes which don't need this work around.
