Even if sst26vf shares the SPINOR_OP_GBULK opcode with
Macronix (ex. MX25U12835F) and Winbound (ex. W25Q128FV),
it has its own Individual Block Protection scheme, which
is also capable to read-lock individual parameter blocks.
Thus the sst26vf's Individual Block Protection scheme will
reside in the sst.c manufacturer driver.
Add support to unlock the entire flash memory. The device
is write-protected by default after a power-on reset cycle
(volatile software protection), in order to avoid inadvertent
writes during power-up. Could do an erase, write, read back,
and compare when MTD_SPI_NOR_SWP_DISABLE_ON_VOLATILE=y.

The Global Block Unlock command has different names depending
on the manufacturer, but always the same command value: 0x98.
Macronix's MX25U12835F names it Gang Block Unlock, Winbond's
W25Q128FV names it Global Block Unlock and Microchip's
SST26VF064B names it Global Block Protection Unlock.
Used in the Individual Block Protection mode, which is mutually
exclusive with the Block Protection mode (BP0-3).

Even if erase type is same as previous region, erase size can be different
if the previous region is overlaid region. Since 'region->size' is assigned
to 'cmd->size' for overlaid region, comparing 'erase->size' and 'cmd->size'
can detect previous overlaid region.

In case of overlaid regions in which their biggest erase size command
overpasses in size the region's size, only the non-overlaid portion of
the sector gets erased. For example, if a Sector Erase command is applied
to a 256-kB range that is overlaid by 4-kB sectors, the overlaid 4-kB
sectors are not affected by the erase.
For overlaid regions, 'region->size' is assigned to 'cmd->size' later in
spi_nor_init_erase_cmd(), so 'erase->size' can be greater than 'len'.

In the case of failure while parsing the partitions, the iterator should
be pre decremented by one before starting to free the memory allocated
by kstrdup(). Because in the failure case, kstrdup() will not succeed
and thus no memory will be allocated for the current iteration.

Pull ARM SoC platform removals from Arnd Bergmann:
"There are a lot of platforms that have not seen any interesting code
changes in the past five years or more.
I made a list and asked around which ones are no longer in use, and
received confirmation about six ARM platforms and the TI C6x
architecture that have all reached the end of their life upstream,
with no known users remaining:
- efm32 - added in 2011, first Cortex-M, no notable changes after 2013
- picoxcell - added in 2011, abandoned after 2012 acquisition
- prima2 - added in 20111, no notable changes since 2015
- tango - added in 2015, sporadic changes until 2017, but abandoned
- u300 - added in 2009, no notable changes since 2013
- zx - added in 2015 for both 32, 2017 for 64 bit, no notable changes
- arch/c6x - added in 2011, but work stalled soon after that
A number of other platforms on the original list turned out to still
have users. In some cases there are out-of-tree patches and users that
plan to contribute them in the future, in other cases the code is
complete and works reliably"

The Ericsson U300 platform was one of two ARM929 based SoC platforms for
mobile phones in ST-Ericsson after the merger of Ericsson with ST-NXP
into ST-Ericsson, the other one being the ST Nomadik.
The platform was not widely adopted in Linux based systems and was
replaced with the far superior ST-Ericsson U8500 in 2011, but Linus
Walleij kept maintaining the code for the whole time.
Linus continues to use the Nomadik machine, but decided to drop
u300 from the kernel as part of this year's spring cleaning.
Thanks for having maintained it all these years.

The OMAP driver may leverage software BCH logic to locate errors while
using its own hardware to detect the presence of errors. This is
achieved with a "mixed" mode which initializes manually the software
BCH internal logic while providing its own OOB layout.
The issue here comes from the fact that the BCH driver has been
updated to only use generic NAND objects, and no longer depend on raw
NAND structures as it is usable from SPI-NAND as well. However, at the
end of the BCH context initialization, the driver checks the validity
of the OOB layout. At this stage, the raw NAND fields have not been
populated yet while being used by the layout helpers, leading to an
invalid layout.
The chosen solution here is to include the BCH structure definition
and to refer to the BCH fields directly (de-referenced as a const
pointer here) to know as early as possible the number of steps and ECC
bytes which have been chosen.
Note: I don't know which commit exactly triggered the error, but the
entire migration to a generic BCH driver got merged in one go, so this
should not be a problem for stable backports.

The initial change breaking the logic is
commit 3d1f08b032dc ("mtd: spinand: Use the external ECC engine logic")
It inadvertently dropped proper OOB support while doing something
else.
Shortly later, half of it got re-integrated by
commit 868cbe2a6dce ("mtd: spinand: Fix OOB read")
(pointing by the way to a more early change which had nothing to do
with the issue). Problem is, this commit failed to revert the faulty
change entirely and missed the logic handling MTD_OPS_AUTO_OOB
requests.
Let's fix this mess by re-inserting the missing part now.

Move the check for mtd->name after the mtd variable has actually been
initialized.
While here, also drop the NULL assignment to the mtd variable as it's
overwritten later on anyways and the NULL value is never read.

I have been fooled by the logic picking the right ECC engine which is
spread across two functions: *init_module() and *_attach(). I thought
this driver was not impacted by the recent changes around the ECC
engines DT parsing logic but in fact it is.

For NOR flashes EC and VID are zeroed out before an erase is issued to
make sure UBI does not mistakenly treat the PEB as used and associate it
with an LEB.
But on some flashes, like the Cypress Semper S28 SPI NOR flash family,
multi-pass page programming is not allowed on the default ECC scheme.
This means zeroing out these magic numbers will result in the flash
throwing a page programming error.
Do not zero out EC and VID for such flashes. A writesize > 1 is an
indication of an ECC-ed flash.

To get better performance, current gpmi driver collected and chained all
small DMA transfers in gpmi_nfc_exec_op, the whole chain triggered and
wait for complete at the end.
But some random DMA timeout found in this new driver, with the help of
ftrace, we found the root cause is as follows:
Take gpmi_ecc_read_page() as an example, gpmi_nfc_exec_op collected 6
DMA transfers and the DMA chain triggered at the end. It waits for bch
completion and check jiffies if it's timeout. The typical function graph
shown below,

63.216730 | 1) ! 379.125 us | }
but it's not gurantee that bch irq handled always after dma irq handled,
sometimes bch_irq comes first and gpmi_nfc_exec_op won't wait anymore,
another gpmi_nfc_exec_op may get invoked before last DMA chain IRQ
handled, this messed up the next DMA chain and causes DMA timeout. Check
the trace log when issue happened.

In the first gpmi_nfc_exec_op, bch_irq comes first and gpmi_nfc_exec_op
exits, but DMA IRQ still not happened yet until the middle of following
gpmi_nfc_exec_op, the first DMA transfer index get messed and DMA get
timeout.
To fix the issue, when there is bch ops in DMA chain, the
gpmi_nfc_exec_op should wait for both completions rather than bch
completion only.

SDX55 uses QPIC version 2.0.0 IP for the NAND controller support.
In this version, DEV_CMD_* registers are moved to operational state,
hence CPU access in BAM mode is restricted. So, skip accessing these
registers and also use a different config for reading ONFI parameters.
