This makes printed info consistent with other kernel messages. After
scanning NAND BBT create_bbt() prints offset of each bad block. This
change makes is easy to verify nand_erase_nand() failure reason.

The reference counting issue happens in several error handling paths
on a refcounted object "nc->dmac". In these paths, the function simply
returns the error code, forgetting to balance the reference count of
"nc->dmac", increased earlier by dma_request_channel(), which may
cause refcount leaks.
Fix it by decrementing the refcount of specific object in those error
paths.

The root of the problem is that we are selecting symbols that have
dependencies. This can cause random configurations that can fail.
The cleanest solution is to avoid using select.
This driver uses interfaces from the OMAP_GPMC driver so we have to
depend on it instead.

Reduce the number of exported symbols by replacing:
- mtd_expert_analysis_warning (the error string)
- mtd_expert_analysis_mode (the boolean)
with a single helper:
- mtd_check_expert_analysis_mode
Calling this helper will both check/return the content of the internal
boolean -which is not exported anymore- and as well conditionally
WARN_ONCE() the user, like it was done before.
While on this function, make the error string local to the helper and
set it const. Only export this helper when CONFIG_DEBUG_FS is defined to
limit the growth of the Linux kernel size only for a debug feature on
production kernels.
Mechanically update all the consumers.

On non-OF enabled platforms (CONFIG_OF is not set), of_match_node() will
expand to NULL. The of_device_id array pointed by the macro will then be
left unused. Let's mark the array __maybe_unused in this case to prevent
compiler warnings.

of_match_ptr() either expands to NULL if !CONFIG_OF, or is transparent
otherwise. There are several drivers using this macro which keep their
of_device_id array enclosed within an #ifdef CONFIG_OF check, these are
considered fine. However, When misused, the of_device_id array pointed
by this macro will produce a warning because it is finally unused when
compiled without OF support.
A number of fixes are possible:
- Always depend on CONFIG_OF, but this will not always work and may
break boards.
- Enclose the compatible array by #ifdef's, this may save a bit of
memory but will reduce build coverage.
- Tell the compiler the array may be unused, if this can be avoided,
let's not do this.
- Just drop the macro, setting the of_device_id array for a non OF
enabled platform is not an issue, it will just be unused.
The latter solution seems the more appropriate, so let's use it.

The brcmnand driver contains a bug in which if a page (example 2k byte)
is read from the parallel/ONFI NAND and within that page a subpage (512
byte) has correctable errors which is followed by a subpage with
uncorrectable errors, the page read will return the wrong status of
correctable (as opposed to the actual status of uncorrectable.)
The bug is in function brcmnand_read_by_pio where there is a check for
uncorrectable bits which will be preempted if a previous status for
correctable bits is detected.
The fix is to stop checking for bad bits only if we already have a bad
bits status.

Interacting with a NAND chip on an IPQ6018 I found that the qcomsmem NAND
partition parser was returning -EPROBE_DEFER waiting for the main smem
driver to load.
This caused the board to reset. Playing about with the probe() function
shows that the problem lies in the core clock being switched off before the
nandc_unalloc() routine has completed.
If we look at how qcom_nandc_remove() tears down allocated resources we see
the expected order is
qcom_nandc_unalloc(nandc);
clk_disable_unprepare(nandc->aon_clk);
clk_disable_unprepare(nandc->core_clk);
dma_unmap_resource(&pdev->dev, nandc->base_dma, resource_size(res),
DMA_BIDIRECTIONAL, 0);
Tweaking probe() to both bring up and tear-down in that order removes the
reset if we end up deferring elsewhere.

to manage High-Speed NAND devices, so it was wrong to assume that only
i.MX6 can achieve EDO timings.
This patch has been tested on a 2048/64 byte NAND (Micron MT29F2G08ABAEAH4).
Kernel mtd tests:
- mtd_nandbiterrs
- mtd_nandecctest

- mtd_readtest
- mtd_speedtest
- mtd_stresstest

What to do when the real rate of the gpmi clock is not equal to the
required one? The solutions proposed in [1] did not lead to a conclusion
on how to validate the clock rate, so, inspired by the document [2], I
consider the rate correct only if not lower or equal to the rate of the
previous edo mode. In fact, in chapter 4.16.2 (NV-DDR) of the document [2],
it is written that "If the host selects timing mode n, then its clock
period shall be faster than the clock period of timing mode n-1 and
slower than or equal to the clock period of timing mode n.". I thought
that it could therefore also be used in this case, without therefore
having to define the valid rate ranges empirically.
For example, suppose that gpmi_nfc_compute_timings() is called to set
edo mode 5 (100MHz) but the rate returned by clk_round_rate() is 80MHz
(edo mode 4). In this case gpmi_nfc_compute_timings() will return error,
and will be called again to set edo mode 4, which this time will be
successful.

Set the controller registers according to the real clock rate. The
controller registers configuration (setup, hold, timeout, ... cycles)
depends on the clock rate of the GPMI. Using the real rate instead of
the ideal one, avoids that this inaccuracy (required_rate - real_rate)
affects the registers setting.
This patch has been tested on two custom boards with i.MX28 and i.MX6
SOCs:
- i.MX28:
required rate 100MHz, real rate 99.3MHz
- i.MX6
required rate 100MHz, real rate 99MHz

Add a BCMA shim to allow us to register the brcmnand driver using the
BCMA bus which provides indirect memory mapped access to SoC registers.
There are a number of registers that need to be byte swapped because
they are natively big endian, coming directly from the NAND chip, and
there is no bus interface unlike the iProc or STB platforms that
performs the byte swapping for us.

Allow a brcmnand_soc instance to provide a custom set of I/O operations
which we will require when using this driver on a BCMA bus which is not
directly memory mapped I/O. Update the nand_{read,write}_reg accordingly
to use the SoC operations if provided.
To minimize the penalty on other SoCs which do support standard MMIO
accesses, we use a static key which is disabled by default and gets
enabled if a soc implementation does provide I/O operations.

of_get_nand_bus_width() had a wrong behavior because:
1/ it ignored the -ENODATA and -EOVERFLOW return values of
of_property_read_u32(). "nand-bus-width" without value was tolerated
while it shouldn't have been according to the devicetree bindings.
2/ returned -EIO when the nand-bus-width was neither 8 nor 16, when it
should have returned -EINVAL instead.
3/ returned the 8 or 16 bus-width integer, but it was never used it its
caller. A simply return 0 on success is enough.

Pull MTD updates from Miquel Raynal:
"MTD core changes:
- mtdchar: Prevent unbounded allocation in MEMWRITE ioctl
- gen_probe: Use bitmap_zalloc() when applicable
- Introduce an expert mode for forensics and debugging purposes
- Clear out unregistered devices a bit more
- Provide unique name for nvmem device
- Remove unused header file <linux/mtd/latch-addr-flash.h>
- Fixed breaking list in __mtd_del_partition.
MTD device changes:
- Warn about failure to unregister mtd device in sst25l, mchp48l640,
mchp23k256, and dataflash drivers.
Raw NAND core changes:
- Export nand_read_page_hwecc_oob_first()
GPMC memory controller for OMAP2 NAND controller changes:
- Add support for AM64 SoC and allow build on K3 platforms
- Use a compatible match table when checking for NAND controller
- Use platform_get_irq() to get the interrupt
Raw NAND controller changes:
- OMAP2 NAND controller:
- Document the missing 'rb-gpios' DT property
- Drop unused variable
- Fix force_8bit flag behaviour for DMA mode
- Move to exec_op interface
- Use platform_get_irq() to get the interrupt
- Renesas:
- Add new NAND controller driver with its bindings and MAINTAINERS entry
- Onenand:
- Remove redundant variable ooblen
- MPC5121:
- Remove unused variable in ads5121_select_chip()
- GPMI:
- Add ERR007117 protection for nfc_apply_timings
- Remove explicit default gpmi clock setting for i.MX6
- Use platform_get_irq_byname() to get the interrupt
- Remove unneeded variable
- Ingenic:
- JZ4740 needs 'oob_first' read page function
- Davinci:
- Rewrite function description
- Avoid duplicated page read
- Don't calculate ECC when reading page
SPI NOR core changes:
- Add Pratyush as SPI NOR co-maintainer.
- Flash parameters initialization was done in a spaghetti way. Clean
flash parameters initialization.
- Rework the flash_info flags and clarify where one should be used.
- Initialize all flash parameters based on JESD216 SFDP where
possible. Flash parameters and settings that are SFDP discoverable
should not be duplicated via flash_info flags at flash declaration.
- Remove debugfs entries that duplicate sysfs entries.
SPI NOR manufacturer driver changes:
- Use late_init() hook in various drivers to make it clear that those
flash parameters are either not declared in the JESD216 SFDP
standard, or the SFDP tables which define those flash parameters
are not defined by the flash.
- Fix mtd size for s3an flashes.
- Write 2 bytes when disabling Octal DTR mode: 1 byte long
transactions are not allowed in 8D-8D-8D mode.
Hyperbus changes:
- Couple of fixes in Renesas hyperbus rpc-if driver to avoid crash on
module remove and for missing check for error value in probe"

platform_get_resource_byname(pdev, IORESOURCE_IRQ, ..) relies on static
allocation of IRQ resources in DT core code, this causes an issue
when using hierarchical interrupt domains using "interrupts" property
in the node as this bypasses the hierarchical setup and messes up the
irq chaining.
In preparation for removal of static setup of IRQ resource from DT core
code use platform_get_irq_byname().
