NOTICE THAT:
"...we don't know whether we need fallthroughs or breaks here and this
is just a change to avoid having new warnings when switching to

See the original thread of discussion here:

So, in preparation to enabling -Wimplicit-fallthrough, this patch silences
the following warnings:

Also, notice that this patch doesn't change any functionality. See the
most recent thread of discussion here:

This patch is part of the ongoing efforts to enable

it differs in the SPI interfacing in significant ways.

This change supports nand-ecc-step-size and nand-ecc-strength fields in

see: Documentation/devicetree/bindings/mtd/brcm,brcmnand.txt
If both nand-ecc-strength and nand-ecc-step-size are not specified in
device tree node for NAND, raw NAND layer does detect ECC information by
reading ONFI extended parameter page for parts using ONFI >= 2.1.
In case of non-ONFI NAND parts there could be a nand_id table entry with
ECC information. If there is valid device tree entry for nand-ecc-strength
and nand-ecc-step-size fields it still shall override the detected values.

The gpmi driver performance suffers from NAND operations being split
in multiple small DMA transfers. This has been forced by the NAND layer
in the former days, but now with exec_op we can use the controller as
intended.
With this patch gpmi_nfc_exec_op becomes the main entry point to NAND
operations. Here all instructions are collected and chained as separate
DMA transfers. In the end whole chain is fired and waited to be
finished. gpmi_nfc_exec_op only does the hardware operations, bad block
marker swapping and buffer scrambling is done by the callers. It's worth
noting that the nand_*_op functions always take the buffer lengths for
the data that the NAND chip actually transfers. When doing BCH we have
to calculate the net data size from the raw data size in some places.
This patch has been tested with 2048/64 and 2048/128 byte NAND on
i.MX6q. mtd_oobtest, mtd_subpagetest and mtd_speedtest run without
errors. nandbiterrs, nandpagetest and nandsubpagetest userspace tests
from mtdutils run without errors and UBIFS can successfully be mounted.

Then, if RE# access time is bigger than RE# pulse width, the real

read performance be worse than that expected.
This patch improves data sampling timing by calculating RE# low level

At present, the flow of calculating AC timing of read/write cycle in SDR
mode is that:
At first, calculate high hold time which is valid for both read and write
cycle using the max value between tREH_min and tWH_min.
Secondly, calculate WE# pulse width using tWP_min.
Thridly, calculate RE# pulse width using the bigger one between tREA_max
and tRP_min.
But NAND SPEC shows that Controller should also meet write/read cycle time.
That is write cycle time should be more than tWC_min and read cycle should
be more than tRC_min. Obviously, we do not achieve that now.
This patch corrects the low level time calculation to meet minimum
read/write cycle time required. After getting the high hold time, WE# low
level time will be promised to meet tWP_min and tWC_min requirement,
and RE# low level time will be promised to meet tREA_max, tRP_min and
tRC_min requirement.

Sometimes the exec_op parser does not choose the optimal pattern if
multiple patterns with optional elements are available. Since the stack
automatically splits operations in multiple exec_op calls, a non-optimal
pattern gets broken up into multiple calls. E.g. an OOB read using the
vf610 driver:
nand: executing subop:
nand: ->CMD [0x00]
nand: ->ADDR [5 cyc: 00 08 ea 94 02]
nand: ->CMD [0x30]
nand: ->WAITRDY [max 200000 ms]
nand: DATA_IN [64 B]
nand: executing subop:
nand: CMD [0x00]
nand: ADDR [5 cyc: 00 08 ea 94 02]
nand: CMD [0x30]
nand: WAITRDY [max 200000 ms]
nand: ->DATA_IN [64 B]
However, the vf610 driver has a pattern which can execute the complete
command in a single go...
This patch makes sure that the longest matching pattern is chosen
instead of the first (potentially only partial) match. With this
change the vf610 reads the OOB in a single exec_op call:
nand: executing subop:
nand: ->CMD [0x00]
nand: ->ADDR [5 cyc: 00 08 c0 1d 00]
nand: ->CMD [0x30]
nand: ->WAITRDY [max 200000 ms]

Cypress' HyperBus is Low Signal Count, High Performance Double Data Rate
Bus interface between a host system master and one or more slave
interfaces. HyperBus is used to connect microprocessor, microcontroller,
or ASIC devices with random access NOR flash memory (called HyperFlash)
or self refresh DRAM (called HyperRAM).
Its a 8-bit data bus (DQ[7:0]) with Read-Write Data Strobe (RWDS)
signal and either Single-ended clock(3.0V parts) or Differential clock
(1.8V parts). It uses ChipSelect lines to select b/w multiple slaves.
At bus level, it follows a separate protocol described in HyperBus
specification[1].
HyperFlash follows CFI AMD/Fujitsu Extended Command Set (0x0002) similar
to that of existing parallel NORs. Since HyperBus is x8 DDR bus,
its equivalent to x16 parallel NOR flash with respect to bits per clock
cycle. But HyperBus operates at >166MHz frequencies.
HyperRAM provides direct random read/write access to flash memory
array.
But, HyperBus memory controllers seem to abstract implementation details
and expose a simple MMIO interface to access connected flash.
Add support for registering HyperFlash devices with MTD framework. MTD
maps framework along with CFI chip support framework are used to support
communicating with flash.
Framework is modelled along the lines of spi-nor framework. HyperBus
memory controller (HBMC) drivers calls hyperbus_register_device() to
register a single HyperFlash device. HyperFlash core parses MMIO access
information from DT, sets up the map_info struct, probes CFI flash and
registers it with MTD framework.
Some HBMC masters need calibration/training sequence[3] to be carried
out, in order for DLL inside the controller to lock, by reading a known
string/pattern. This is done by repeatedly reading CFI Query
Identification String. Calibration needs to be done before trying to detect
flash as part of CFI flash probe.
HyperRAM is not supported at the moment.

HyperFlash devices are compliant with CFI AMD/Fujitsu Extended Command
Set (0x0002) for flash operations, therefore
drivers/mtd/chips/cfi_cmdset_0002.c can be used as is. But these devices
do not support DQ polling method of determining chip ready/good status.
These flashes provide Status Register whose bits can be polled to know
status of flash operation.
Cypress HyperFlash datasheet here[1], talks about CFI Amd/Fujitsu
Extended Query version 1.5. Bit 0 of "Software Features supported" field
of CFI Primary Vendor-Specific Extended Query table indicates
presence/absence of status register and Bit 1 indicates whether or not
DQ polling is supported. Using these bits, its possible to determine
whether flash supports DQ polling or need to use Status Register.
Add support for polling Status Register to know device ready/status of
erase/write operations when DQ polling is not supported.
Print error messages on erase/program failure by looking at related
Status Register bits.

The reason this patch is needed is in the case where a bootloader leaves
the QSPI controller in a reset state, or a state where init cannot occur
successfully, the patch will put the QSPI controller into a clean state.

there are written at different times: some use markdown,
some use their own peculiar logic to split sections.
Convert everything to ReST without affecting too much
the author's style and avoiding adding uneeded markups.
The conversion is actually:
- add blank lines and identation in order to identify paragraphs;
- fix tables markups;
- add some lists markups;
- mark literal blocks;
- adjust title markups.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

There's a new driver using the SPI memory interface of the
SPI framework at spi/spi-stm32-qspi.c, which can be used
together with m25p80.c to replace the functionality of
this SPI NOR driver.
The "new" driver uses the same dt properties and not affects
the legacy compatibility.
