1e2c5bb9e7 mtd: nand: Fix nand write error with bad block addresses above 32-bit
Nand writes should skip the bad blocks with "nand write" command.
In case of bad blocks with above 32-bit address, nand_block_isbad()
returns false due to truncated bad block address.

In below code segment,

	if (nand_block_isbad(mtd, offset & ~(mtd->erasesize - 1)))

offset is 64-bit and mtd->erasesize is 32-bit, hence the truncation is
happening. Cast 'mtd->erasesize' with loff_t to fix this issue.

720fcb27e0 mtd: spinand: micron: identify SPI NAND device with Continuous Read mode
Add SPINAND_HAS_CR_FEAT_BIT flag to identify the SPI NAND device with
the Continuous Read mode.

Some of the Micron SPI NAND devices have the "Continuous Read" feature
enabled by default, which does not fit the subsystem needs.

In this mode, the READ CACHE command doesn't require the starting column
address. The device always output the data starting from the first
column of the cache register, and once the end of the cache register
reached, the data output continues through the next page. With the
continuous read mode, it is possible to read out the entire block using
a single READ command, and once the end of the block reached, the output
pins become High-Z state. However, during this mode the read command
doesn't output the OOB area.

Hence, we disable the feature at probe time.

while mtd_parse_partitions() uses int to work with these values. When

addf358bac core: add support for U_BOOT_DRIVER_ALIAS
Currently when using OF_PLATDATA the binding between devices and drivers
is done trying to match the compatible string in the node with a driver
name. However, usually a single driver supports multiple compatible strings
which causes that only devices which its compatible string matches a
driver name get bound.

To overcome this issue, this patch adds the U_BOOT_DRIVER_ALIAS macro,
which generates no code at all, but allows an easy way to declare driver
name aliases. Thanks to this, dtoc could be improve to look for the driver
name based on its alias when it populates the U_BOOT_DEVICE entry.

However driver names are not strictly defined, and also there are different

In order to make things a bit more clear, rename the drivers names. This

56c4046038 spi: Convert CONFIG_DM_SPI* to CONFIG_$(SPL_TPL_)DM_SPI*
This change allows more fine tuning of driver model based SPI support in
SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI
support in SPL and TPL via Kconfig option.

Before this change it was necessary to use:
    /* SPI Flash Configs */
    #if defined(CONFIG_SPL_BUILD)
    #undef CONFIG_DM_SPI
    #undef CONFIG_DM_SPI_FLASH
    #undef CONFIG_SPI_FLASH_MTD
    #endif

in the ./include/configs/<board>.h, which is error prone and shall be
avoided when we strive to switch to Kconfig.

The goal of this patch:

Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL).
Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must
still support non DM driver.

Another use case is the conversion of non DM/DTS SPI driver to support
DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the
distinction is needed in Kconfig (also if SPL version of the driver
supports OF_PLATDATA).

In the end of the day one would have to support following use cases (in
single driver file - e.g. mxs_spi.c):

- U-Boot proper driver supporting DT/DTS
- U-Boot proper driver without DT/DTS support (deprecated)
- SPL driver without DT/DTS support
- SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to
  run full blown DT/DTS)
- SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained
  environment with no fitImage and OF_LIBFDT support).

Some boards do require SPI support (with DM) in SPL (TPL) and some only
have DM_SPI{_FLASH} defined to allow compiling SPL.

This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI)
and provides corresponding defines in Kconfig.

f12f96cfaf sf: Drop spl_flash_get_sw_write_prot
The get_sw_write_prot API is used to get the write-protected
bits of flash by reading the status register and other wards
it's API for reading register bits.

1) This kind of requirement can be achieved using existing
   flash operations and flash locking API calls instead of
   making a separate flash API.
2) Technically there is no real hardware user for this API to
   use in the source tree.
3) Having a flash operations API for simple register read bits
   also make difficult to extend the flash operations.
4) Instead of touching generic code, it is possible to have
   this functionality inside spinor operations in the form of
   flash hooks or fixups for associated flash chips.

Considering all these points, this patch drops the get_sw_write_prot
and associated code bases.

5f8d677839 mtd: spinand: toshiba: Rename function name to change suffix and prefix (8Gbit)
The suffix was changed from "G" to "J" to classify between 1st generation
and 2nd generation serial NAND devices (which now belong to the Kioxia
brand).
As reference that's
1st generation device of 1Gbit product is "TC58CVG0S3HRAIG"
2nd generation device of 1Gbit product is "TC58CVG0S3HRAIJ".

The 8Gbit type "TH58CxG3S0HRAIJ" is new to Kioxia's serial NAND lineup and
the prefix was changed from "TC58" to "TH58".

Thus the functions were renamed from tc58cxgxsx_*() to tx58cxgxsxraix_*().

1c193c0c6e mtd: rawnand: denali: deassert write protect pin
[ Linux commit 9afbe7c0140f663586edb6e823b616bd7076c00a ]

If the write protect signal from this IP is connected to the NAND
device, this IP can handle the WP# pin via the WRITE_PROTECT
register.

The Denali NAND Flash Memory Controller User's Guide describes
this register like follows:

  When the controller is in reset, the WP# pin is always asserted
  to the device. Once the reset is removed, the WP# is de-asserted.
  The software will then have to come and program this bit to
  assert/de-assert the same.

    1 - Write protect de-assert
    0 - Write protect assert

The default value is 1, so the write protect is de-asserted after
the reset is removed. The driver can write to the device unless
someone has explicitly cleared register before booting the kernel.

The boot ROM of some UniPhier SoCs (LD4, Pro4, sLD8, Pro5) is the
case; the boot ROM clears the WRITE_PROTECT register when the system
is booting from the NAND device, so the NAND device becomes read-only.

Set it to 1 in the driver in order to allow the write access to the
device.

-----------------------------------------------------------------

This patch does a check for the uncorrectable failure in the following steps:

   [0] set the threshold.
       The threshold is set based on the truth:
       "A single 0 bit will lead to gf_len(13 or 14) bits 0 after the BCH
        do the ECC."

        For the sake of safe, we will set the threshold with half the gf_len, and
        do not make it bigger the ECC strength.

   [1] count the bitflips of the current ECC chunk, assume it is N.

   [2] if the (N <= threshold) is true, we continue to read out the page with
       ECC disabled. and we count the bitflips again, assume it is N2.
       (We read out the whole page, not just a chunk, this makes the check
        more strictly, and make the code more simple.)

   [3] if the (N2 <= threshold) is true again, we can regard this is a erased
       page. This is because a real erased page is full of 0xFF(maybe also has
       several bitflips), while a page contains the 0xFF data will definitely
       has many bitflips in the ECC parity areas.

   [4] if the [3] fails, we can regard this is a page filled with the '0xFF'
       data.

616f03daba mtd: gpmi: change the BCH layout setting for large oob NAND
The code change updated the NAND driver BCH ECC layout algorithm to
support large oob size NAND chips(oob > 1024 bytes) and proposed a new
way to set ECC layout.

Current implementation requires each chunk size larger than oob size so
the bad block marker (BBM) can be guaranteed located in data chunk. The
ECC layout always using the unbalanced layout(Ecc for both meta and
Data0 chunk), but for the NAND chips with oob larger than 1k, the driver
cannot support because BCH doesn’t support GF 15 for 2K chunk.

The change keeps the data chunk no larger than 1k and adjust the ECC
strength or ECC layout to locate the BBM in data chunk. General idea for
large oob NAND chips is

1.Try all ECC strength from the minimum value required by NAND spec to
the maximum one that works, any ECC makes the BBM locate in data chunk
can be chosen.

2.If none of them works, using separate ECC for meta, which will add one
extra ecc with the same ECC strength as other data chunks. This extra
ECC can guarantee BBM located in data chunk, of course, we need to check
if oob can afford it.

Previous code has two methods for ECC layout setting, the
legacy_calc_ecc_layout and calc_ecc_layout_by_info, the difference
between these two methods is, legacy_calc_ecc_layout set the chunk size
larger chan oob size and then set the maximum ECC strength that oob can
afford. While the calc_ecc_layout_by_info set chunk size and ECC
strength according to NAND spec. It has been proved that the first
method cannot provide safe ECC strength for some modern NAND chips, so
in current code,

1. Driver read NAND parameters first and then chose the proper ECC
layout setting method.

2. If the oob is large or NAND required data chunk larger than oob size,
chose calc_ecc_for_large_oob, otherwise use calc_ecc_layout_by_info

3. legacy_calc_ecc_layout only used for some NAND chips does not contains
necessary information. So this is only a backup plan, it is NOT
recommended to use these NAND chips.

27d706937a ARM: zynq: Fix invalid check on NAND_CMD_NONE.
The end_cmd field in the variables cmd_phase_addr and data_phase_addr
contains the value 0xFF when the end_cmd equals NAND_CMD_NONE. This
should be 0x00.

This is caused by comparing NAND_CMD_NONE (int) with end_cmd (u8).
end_cmd will be promoted by the int value -1 and therefore is not equal
to 0xFF. Solved by casting NAND_CMD_NONE to u8 which will avoid int
promotion.

exactly the same for all the architectures that support them.

Factor them out to <linux/dma-mapping.h>, and make all drivers to
include <linux/dma-mapping.h> instead of <asm/dma-mapping.h>.

If we need to differentiate them for some architectures, we can
move the generic definitions to <asm-generic/dma-mapping.h>.

Add some comments to the helpers. The concept is quite similar to
the DMA-API of Linux kernel. Drivers are agnostic about what is
going on behind the scene. Just call dma_map_single() before the
DMA, and dma_unmap_single() after it.

33672c970b mtd: rawnand: denali-spl: Add missing hardware init on SoCFPGA
On Altera SoCFPGA, upon either cold-boot or power-on reset, the
Denali NAND IP is initialized by the BootROM ; upon warm-reset,
the Denali NAND IP is NOT initialized by BootROM. In fact, upon
warm-reset, the SoCFPGA BootROM checks whether the SPL image in
on-chip RAM is valid and if so, completely skips re-loading the
SPL from the boot media.

This does sometimes lead to problems where the software left
the boot media in inconsistent state before warm-reset, and
because the BootROM does not reset the boot media, the boot
media is left in this inconsistent state, often until another
component attempts to access the boot media and fails with an
difficult to debug failure. To mitigate this problem, the SPL
on Altera SoCFPGA always resets all the IPs on the SoC early
on boot.

This results in a couple of register values, pre-programmed by
the BootROM, to be lost during this reset. To restore correct
operation of the IP on SoCFPGA, these values must be programmed
back into the controller by the driver. Note that on other SoCs
which do not use the HW-controlled bootstrap, more registers
may have to be programmed.

This also aligns the SPL behavior with the full Denali NAND
driver, which sets these values in denali_hw_init().

MTD support is required (there are two different symbols for that, one
for U-Boot and one for the SPL).

Now that all defconfigs have been fixed, we can stop the logic where
enabling a command selects the core files to compile. This logic is
broken since selecting a symbol with a 'depends on' will not enforce

85f7e9d547 mtd: spi: SPI_FLASH_MTD depends on MTD
It is already the case that all defconfigs with SPI_FLASH_MTD also
declare using MTD, but let's make this consistent and enforce it in
Kconfig. Most of the time SPI_FLASH_MTD is used in conjunction with
UBI, which already depends on MTD.

e365de9051 drivers: nand: brcmnand: fix nand_chip ecc layout structure
The current brcmnand driver is based on 4.18 linux kernel which uses
mtd_set_ooblayout to set ecc layout. But nand base code in u-boot is from
old kernel which does not use this new API and expect nand_chip.ecc.layout
structure to be set. This cause nand_scan_tail function running into a bug
check if the device has a different oob size than the default ones.

This patch ports the brcmstb_choose_ecc_layout function from kernel 4.6.7
that supports the ecc layout struture and replaces the mtd_set_ooblayout
method

832ce20278 mtd: spi: Clean up usage of CONFIG_SPI_FLASH_MTD
Most boards currently use SPI_FLASH_MTD only in U-Boot proper, not in
SPL. They often rely on hacks in the board header files to include
this option conditionally. To be able to fix this, we previously
introduced a separate option SPL_SPI_FLASH_MTD.

Therefore we can now adjust the Makefile and change the code in
sf_probe.c and sf_internal.h to use CONFIG_IS_ENABLED(SPI_FLASH_MTD).

We also need to move all occurences of CONFIG_SPI_FLASH_MTD from the
header files to the according defconfigs. The affected boards are
socfpga, aristainetos, cm_fx6, display5, ventana, rcar-gen2, dh_imx6
and da850evm.

We do this all in one patch to guarantee bisectibility.

This change was tested with buildman to make sure it does not
introduce any regressions by comparing the resulting binary sizes.

Some users of static UBI volumes implement their own integrity check,
thus making the volume CRC check done at open time useless. For
instance, this is the case when one use the ubiblock + dm-verity +
squashfs combination, where dm-verity already checks integrity of the
block device but this time at the block granularity instead of verifying
the whole volume.

Skipping this test drastically improves the boot-time.

1d43e24b94 i.MX6: nand: add nandbcb command for imx
Writing/updating boot image in nand device is not
straight forward in i.MX6 platform and it requires
boot control block(BCB) to be configured.

It becomes difficult to use uboot 'nand' command to
write BCB since it requires platform specific attributes
need to be taken care of.

It is even difficult to use existing msx-nand.c driver by
incorporating BCB attributes like mxs_dma_desc does
because it requires change in mtd and nand command.

So, cmd_nandbcb implemented in arch/arm/mach-imx

BCB contains two data structures, Firmware Configuration Block(FCB)
and Discovered Bad Block Table(DBBT). FCB has nand timings,
DBBT search area, page address of firmware.

On summary, nandbcb update will
- erase the entire partition
- create BCB by creating 2 FCB/DBBT block followed by
  1 FW block based on partition size and erasesize.
- fill FCB/DBBT structures
- write FW/SPL on FW1
- write FCB/DBBT in first 2 blocks

for nand boot, up on reset bootrom look for FCB structure in
first block's if FCB found the nand timings are loaded for
further reads. once FCB read done, DTTB will load and finally
firmware will be loaded which is boot image.

Refer section "NAND Boot" from doc/imx/common/imx6.txt for more usage
information.

6ea31cce0b ubispl: add support for loading volumes by name
The motivation is to use the UBI atomic volume rename functionality to
allow double copy software updates on UBI. To that end the SPL is
configured to always load the same volume name (e.g. "u-boot"),
whereas a software updater always installs into the secondary volume
"u-boot_r". After successful installation, these two volume names are
switched.

This extension is protected by #ifdefs as it will somewhat slow down
loading of volumes by id. This is because the code needs to disable
the optimization of ignoring all volume ids which are not
to-be-loaded, since these can only be resolved after attaching.

This adds two vtbl related functions from Linux, which are taken from
the same kernel version as the current main U-Boot UBI code (Linux 4.2
64291f7db5bd8).

60e2bf4678 mtd: spi-nor: fix page program issue when using spi-mem driver
Some SPI controllers can't write nor->page_size bytes in a single step
because their TX FIFO is too small, but when that happens we should
make sure a WRITE_EN command before each write access and READ_SR command
after each write access is issued.

We should allow nor->write() to return a size that is smaller than the
requested write size to gracefully handle this case.

Also, the spi_nor_write_data() should return the actual number of bytes
that were written during the spi_mem_exec_op() operation.

This patch is a combination of two commits backported from kernel:

  commit 630d6bd8a3b4 ("mtd: spi-nor: Support controllers with limit ...")
  commit 3baa8ec88c2f ("mtd: devices: m25p80: Make sure WRITE_EN is ...")

b0cc1b846f dm: spi: Read default speed and mode values from DT
This patch update the behavior introduced by
commit 96907c0fe5 ("dm: spi: Read default speed and mode values from DT")

In case of DT boot, don't read default speed and mode for SPI from
CONFIG_* but instead read from DT node. This will make sure that boards
with multiple SPI/QSPI controllers can be probed at different
bus frequencies and SPI modes.

Remove also use in boards of the value speed=0 (no more supported)
for ENV in SPI by using CONFIG_ENV_SPI_MAX_HZ=0.

DT values will be always used when available (full DM support of
SPI slave with available DT node) even if speed and mode are requested;
for example in splash screen support (in splash_sf_read_raw)
or in SPL boot (in spl_spi_load_image).
The caller of spi_get_bus_and_cs() no more need to force speed=0.

But the current behavior don't change if the SPI slave is not
present (device with generic driver is created automatically)
or if platdata is used (CONFIG_OF_PLATDATA).

This however also changes the behavior of the execution of the erase

one transfer request to the SPI NOR driver. The former was how U-Boot
behaved before the SPI NOR framework was imported and the later was
introduced by the SPI NOR framework. The former is more optimal, so
keep that.

3f3aef4b9d mtd: fix Coverity integer handling issue
A Coverity robot reported an integer handling issue

    (mtd_div_by_ws(mtd->size, mtd) - mtd_div_by_ws(offs, mtd)) *
    mtd_oobavail(mtd, ops)

While such overflow will certainly never happen due to the numbers
handled, it is cleaner to fix this operation anyway.

The problem is that all the maths include 32-bit quantities, while the
result is stored in an explicit 64-bit value.

As maxooblen will just be compared with a size_t, let's change the
type of the variable to a size_t. This will not fix anything but will
clarify a bit the situation. Then, do an explicit cast to fix Coverity
warning.

Currently the spl system calls nand_init which does nothing.
It isn't until an attempt to load from NAND that it gets initialized.
Subsequent attempts to load just skip the initialization  because
NAND is already initialized.

This moves the contents of mxs_nand_init to nand_init.  In the event
of an error, it clears the number of nand chips found.  Any
attempts to use nand will check if there are nand chips available
instead of actually doing the initialization at that time. If there
are none, it will return an error to the higher level calls.

mxs_nand_init_dma is only referenced from mxs_nand.c.  It's not
referenced in any headers or outside code, so this patch
defines it as static.

5ae585ba3a MTD: mxs_nand: Fix BCH read timeout error on boards requiring ECC
The LogicPD board uses a Micron Flash with ECC.  To boot this from
SPL, the ECC needs to be correctly configured or the BCH engine
times out.

778572d7cb mtd: spi: Add lightweight SPI flash stack for SPL
Add a tiny SPI flash stack that just supports reading data/images from
SPI flash. This is useful for boards that have SPL size constraints and
would need to use SPI flash framework just to read images/data from
flash. There is approximately 1.5 to 2KB savings with this.

Based on prior work of reducing spi flash id table by

2ee6705be0 mtd: spi: sf_probe: Add "jedec, spi-nor" compatible string
Linux uses "jedec,spi-nor" as compatible string for JEDEC compatible
SPI Flash device nodes. Therefore make U-Boot also to look for the same
compatible string so that we can use Linux DTS files as is.
