c7a87ceb17 mtd: rawnand: sunxi: Add A23/A33 DMA support with extra MBUS configuration
Allwinner NAND controllers can make use of DMA to enhance the I/O
throughput thanks to ECC pipelining. DMA handling with A23/A33 NAND IP
is a bit different than with the older SoCs, hence the introduction of
a new compatible to handle:
* the differences between register offsets,
* the burst length change from 4 to minimum 8,
* manage SRAM accesses through MBUS with extra configuration.

4f032640bf Revert "mtd: rawnand: sunxi: Add A23/A33 DMA support"
This reverts commit c49836f05a.

The commit is wrong and its approach actually does not work. Let's
revert it in order to add the feature with a clean patch.

c403ec33b6 mtd: rawnand: ingenic: Fix ingenic_ecc dependency
If MTD_NAND_JZ4780 is y and MTD_NAND_JZ4780_BCH is m,
which select CONFIG_MTD_NAND_INGENIC_ECC to m, building fails:

drivers/mtd/nand/raw/ingenic/ingenic_nand.o: In function `ingenic_nand_remove':
ingenic_nand.c:(.text+0x177): undefined reference to `ingenic_ecc_release'
drivers/mtd/nand/raw/ingenic/ingenic_nand.o: In function `ingenic_nand_ecc_correct':
ingenic_nand.c:(.text+0x2ee): undefined reference to `ingenic_ecc_correct'

To fix that, the ingenic_nand and ingenic_ecc modules have been fused
into one single module.
- The ingenic_ecc.c code is now compiled in only if
  $(CONFIG_MTD_NAND_INGENIC_ECC) is set. This is now a boolean instead
  of tristate.
- To avoid changing the module name, the ingenic_nand.c file is moved to
  ingenic_nand_drv.c. Then the module name is still ingenic_nand.
- Since ingenic_ecc.c is no more a module, the module-specific macros
  have been dropped, and the functions are no more exported for use by
  the ingenic_nand driver.

a126483e82 mtd: spinand: Fix max_bad_eraseblocks_per_lun info in memorg
The 1Gb Macronix chip can have a maximum of 20 bad blocks, while
the 2Gb version has twice as many blocks and therefore the maximum
number of bad blocks is 40.

The 4Gb GigaDevice GD5F4GQ4xA has twice as many blocks as its 2Gb
counterpart and therefore a maximum of 80 bad blocks.

191f5c2ed4 mtd: spi-nor: use 16-bit WRR command when QE is set on spansion flashes
SPI memory devices from different manufacturers have widely
different configurations for Status, Control and Configuration
registers. JEDEC 216C defines a new map for these common register
bits and their functions, and describes how the individual bits may
be accessed for a specific device. For the JEDEC 216B compliant
flashes, we can partially deduce Status and Configuration registers
functions by inspecting the 16th DWORD of BFPT. Older flashes that
don't declare the SFDP tables (SPANSION FL512SAIFG1 311QQ063 A ©11
SPANSION) let the software decide how to interact with these registers.

The commit dcb4b22eea ("spi-nor: s25fl512s supports region locking")
uncovered a probe error for s25fl512s, when the Quad Enable bit CR[1]
was set to one in the bootloader. When this bit is one, only the Write
Status (01h) command with two data byts may be used, the 01h command with
one data byte is not recognized and hence the error when trying to clear
the block protection bits.

Fix the above by using the Write Status (01h) command with two data bytes
when the Quad Enable bit is one.

Backward compatibility should be fine. The newly introduced
spi_nor_spansion_clear_sr_bp() is tightly coupled with the
spansion_quad_enable() function. Both assume that the Write Register
with 16 bits, together with the Read Configuration Register (35h)
instructions are supported.

b2b5921fe4 mtd: rawnand: initialize ntargets with maxchips
memorg->ntargets is initialized with '1'. It should be initialized with
the maxchips argument from nand_scan() instead. Otherwise multi chip
support errors out on the secondary chip selects when trying to call
nand_reset() on them:

WARNING: CPU: 0 PID: 1 at drivers/mtd/nand/raw/internals.h:114
nand_reset_op+0x194/0x1c4

With this memorg->ntargets is initialized with the maximum number of
chip selects supported by the driver. After having detected the number
of actually connected chips memory->ntargets is updated with that
number.

2127982895 mtd: rawnand: vf610_nfc: add initializer to avoid -Wmaybe-uninitialized
This prepares to move CONFIG_OPTIMIZE_INLINING from x86 to a common
place.  We need to eliminate potential issues beforehand.

Kbuild test robot has never reported -Wmaybe-uninitialized warning for
this probably because vf610_nfc_run() is inlined by the x86 compiler's
inlining heuristic.

If CONFIG_OPTIMIZE_INLINING is enabled for a different architecture and
vf610_nfc_run() is not inlined, the following warning is reported:

  drivers/mtd/nand/raw/vf610_nfc.c: In function `vf610_nfc_cmd':
  drivers/mtd/nand/raw/vf610_nfc.c:455:3: warning: `offset' may be used uninitialized in this function [-Wmaybe-uninitialized]

     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
              nfc->regs + NFC_MAIN_AREA(0) + offset,

b7cf5e2830 mtd: afs: add v2 partition parsing
The AFS v2 partition type appear in later ARM reference designs
such as RealView, Versatile Express and the 64bit Juno Development
Platform.

The image informations is padded with a 32bit word (4 bytes) on
the 32bit platforms and a 64bit word (8 bytes) on the 64bit
platforms. The boot monitor source code gives at hand that this
is because the first entry in the struct mapped over the image
information is a "next" pointer for a linked list, filled in
by firmware after reading in the info block, and always zero
in the flash. We adjust padding by checking what padding gives
the right checksum.

This was tested on:
- Integrator/AP (v1 partitions)
- RealView PB11MPCore (v2 32bit partitions)
- Juno Development System (v2 64bit partitions)

All systems display the images in flash very nicely as separate
partitions, e.g on Juno:

4 afs partitions found on MTD device 8000000.flash
Creating 4 MTD partitions on "8000000.flash":
0x000000040000-0x0000000c0000 : "fip"
0x000000ec0000-0x0000018c0000 : "Image"
0x000000f00000-0x000000f40000 : "juno"
0x000003ec0000-0x000003f00000 : "bl1"

1fca1f6abb mtd: afs: simplify partition parsing
This simplifies the AFS partition parsing to make the code
more straight-forward and readable.

Before this patch the code tried to calculate the memory required
to hold the partition info by adding up the sizes of the strings
of the names and adding that to a single memory allocation,
indexing the name pointers in front of the struct mtd_partition
allocations so all allocated data was in one chunk.

This is overzealous. Instead use kstrdup and bail out,
kfree():ing the memory used for MTD partitions and names alike
on the errorpath.

In the process rename the index variable from idx to i.
