0f2c632b8c mtd: spinand: add support for ESMT F50x1G41LB
Adaptation of Linux commit d74c36480a67

This patch adds support for ESMT F50L1G41LB and F50D1G41LB.
It seems that ESMT likes to use random JEDEC ID from other vendors.
Their 1G chips uses 0xc8 from GigaDevice and 2G/4G chips uses 0x2c from
Micron. For this reason, the ESMT entry is named esmt_c8 with explicit
JEDEC ID in variable name.

961c3e9f12 mtd: spi-nor-core: Implement spi_nor_read_sfdp_dma_unsafe() for sfdp parse
During SFDP header parse and BFPT parse, structures in stack are used
to perform spi_nor_read_sfdp() which expects a dma-safe buffer.

This commit introduces spi_nor_read_sfdp_dma_unsafe() to wrap
spi_nor_read_sfdp() using a kmalloc'ed bounce buffer which is
the same implementation in Linux (drivers/mtd/spi-nor/sfdp.c).

8502b5bf20 test: spl: Add a test for NAND
Add a SPL test for the NAND load method. We use some different functions to
do the writing from the main test since things like nand_write_skip_bad
aren't available in SPL.

We disable BBT scanning, since scan_bbt is only populated when not in SPL.
We use nand_spl_loaders.c as it seems to be common to at least a few boards
already. However, we do not use nand_spl_simple.c because it would require
us to implement cmd_ctrl.  The various nand load functions are adapted from
omap_gpmc. However, they have been modified for simplicity/correctness.

bc8e8a4bfa nand: Add sandbox driver
Add a sandbox NAND flash driver to facilitate testing. This driver supports
any number of devices, each using a single chip-select. The OOB data is
stored in-band, with the separation enforced through the API.

For now, create two devices to test with. The first is a very small device
with basic ECC. The second is an 8G device (chosen to be larger than 32
bits). It uses ONFI, with the values copied from the datasheet. It also
doesn't need too strong ECC, which speeds things up.

Although the nand subsystem determines the parameters of a chip based on
the ID, the driver itself requires devicetree properties for each
parameter. We do not derive parameters from the ID because parsing the ID
is non-trivial. We do not just use the parameters that the nand subsystem
has calculated since that is something we should be testing. An exception
is made for the ECC layout, since that is difficult to encode in the device
tree and is not a property of the device itself.

Despite using file I/O to access the backing data, we do not support using
external files. In my experience, these are unnecessary for testing since
tests can generally be written to write their expected data beforehand.
Additionally, we would need to store the "programmed" information somewhere
(complicating the format and the programming process) or try to detect
whether block are erased at runtime (degrading probe speeds).

Information about whether each page has been programmed is stored in an
in-memory buffer. To simplify the implementation, we only support a single
program per erase. While this is accurate for many larger flashes, some
smaller flashes (512 byte) support multiple programs and/or subpage
programs. Support for this could be added later as I believe some
filesystems expect this.

To test ECC, we support error-injection. Surprisingly, only ECC bytes in
the OOB area are protected, even though all bytes are equally susceptible
to error. Because of this, we take care to only corrupt ECC bytes.
Similarly, because ECC covers "steps" and not the whole page, we must take
care to corrupt data in the same way.

38ef64e6ce spl: nand: Set bl_len to page size
Since commit 34793598c8 ("mtd: nand: mxs_nand_spl: Remove the page aligned
access") there are no longer any users of nand_get_mtd. However, it is
still important to know what the page size is so we can allocate a
large-enough buffer. If the image size is not page-aligned, we will go off
the end of the buffer and clobber some memory.

Introduce a new function nand_page_size which returns the page size. For
most drivers it is easy to determine the page size. However, a few need to
be modified since they only keep the page size around temporarily.

It's possible that this patch could cause a regression on some platforms if
the offset is non-aligned and there is invalid address space immediately
before the load address. spl_load_legacy_img does not (except when
compressing) respect bl_len, so only boards with SPL_LOAD_FIT (8 boards) or
SPL_LOAD_IMX_CONTAINER (none in tree) would be affected.

the spinand core and makes backporting features and fixes easier.

This does not include the latest kernel implementation as this would
require a substantial amount of extra work due to the missing
ECC engine abstraction layer in U-Boot.

b20913e3cb mtd/spinand: rework detect procedure for different READ_ID operation
Currently there are 3 different variants of read_id implementation:
1. opcode only. Found in GD5FxGQ4xF.
2. opcode + 1 addr byte. Found in GD5GxGQ4xA/E
3. opcode + 1 dummy byte. Found in other currently supported chips.

Original implementation was for variant 1 and let detect function
of chips with variant 2 and 3 to ignore the first byte. This isn't
robust:

1. For chips of variant 2, if SPI master doesn't keep MOSI low
during read, chip will get a random id offset, and the entire id
buffer will shift by that offset, causing detect failure.

2. For chips of variant 1, if it happens to get a devid that equals
to manufacture id of variant 2 or 3 chips, it'll get incorrectly
detected.

This patch reworks detect procedure to address problems above. New
logic do detection for all variants separatedly, in 1-2-3 order.
Since all current detect methods do exactly the same id matching
procedure, unify them into core.c and remove detect method from
manufacture_ops.

This is a rework of Chuanhong Guo <gch981213@gmail.com> patch
submitted to linux kernel

d6b4359e50 mtd: nand: raw: atmel: Add error handling when rb-gpios missing
Adapt behaviour to Linux kernel driver.

The return value of gpio_request_by_name_nodev() was not checked before,
and thus in case 'rb-gpios' was missing in DT, rb.type was set to
ATMEL_NAND_GPIO_RB nevertheless, leading to output like this for
example (on sam9x60-curiosity with the line removed from dts):

    NAND:  Could not find valid ONFI parameter page; aborting
    device found, Manufacturer ID: 0xc2, Chip ID: 0xdc
    Macronix NAND 512MiB 3,3V 8-bit
    512 MiB, SLC, erase size: 256 KiB, page size: 4096, OOB size: 64
    atmel-nand-controller nand-controller: NAND scan failed: -22
    Failed to probe nand driver (err = -22)
    Failed to initialize NAND controller. (error -22)
    0 MiB

Note: not having that gpio assigned in dts is possible, the driver does
not override nand_chip->dev_ready() then and a generic solution is used.

d223dcf31a drivers/mtd/nvmxip: Trigger post bind as probe on driver level
Perform all the block device creation only once, after the driver itself
successfully bound. Do not do this in uclass post bind, as this might be
triggered multiple times. For example the ut_dm_host test triggers this
and triggers a memory leak that way, since there are now multiple block
devices created using the blk_create_devicef() .

To retain the old probe-on-boot behavior, set DM_FLAG_PROBE_AFTER_BIND
flag in uclass post_bind callback, so the driver model would probe the
driver at the right time.

Rename the function as well, to match similar functions in
other block-related subsystems, like the mmc one.

3d17ee4533 mtd: nand: raw: rockchip_nfc: copy hwecc PA data to oob_poi buffer
Rockchip boot blocks are written per 4 x 512 byte sectors per page.
Each page must have a page address (PA) pointer in OOB to the next page.
Pages are written in a pattern depending on the NAND chip ID.
This logic used to build a page pattern table is not fully disclosed and
is not easy to fit in the MTD framework.
The formula in rk_nfc_write_page_hwecc() function is not correct.
Make hwecc and raw behavior identical.
Generate boot block page address and pattern for hwecc in user space
and copy PA data to/from the already reserved last 4 bytes before EEC
in the chip->oob_poi data layout.
