When the flash is handed to us in a stateful mode like 8D-8D-8D, it is
difficult to detect the mode the flash is in. One option is to read SFDP
in all modes and see which one gives the correct "SFDP" signature, but
not all flashes support SFDP in 8D-8D-8D mode.
Further, even if you detect the mode of the flash via SFDP, you still
have the problem of actually reading the ID. The Read ID command is not
standardized across flash vendors. Flashes can have different dummy
cycles needed for reading the ID. Some flashes even expect a 4-byte
dummy address with the Read ID command. All this information cannot be
obtained from the SFDP table.
So, perform a Software Reset sequence before reading the ID and
initializing the flash. A Soft Reset will bring back the flash in its
default protocol mode assuming no non-volatile configuration was set.
This will let us detect the flash even if ROM hands it to us in Octal
DTR mode.
To accommodate cases where there is more than one flash on a board, and
only one of them needs a soft reset, failure to reset is not made fatal,
and we still try to read ID if possible.

On probe, the SPI NOR core will put a flash in 8D-8D-8D mode if it
supports it. But Linux as of now expects to get the flash in 1S-1S-1S
mode. Handing the flash to Linux in Octal DTR mode means the kernel will
fail to detect the flash.
So, we need to reset to Power-on-Reset (POR) state before handing off
the flash. A Software Reset command can be used to do this.
One limitation of the soft reset is that it will restore state from
non-volatile registers in some flashes. This means that if the flash was
set to 8D mode in a non-volatile configuration, a soft reset won't help.
This commit assumes that we don't set any non-volatile bits anywhere,
and the flash doesn't have any non-volatile Octal DTR mode
configuration.
Since spi-nor-tiny doesn't (and likely shouldn't) have
spi_nor_soft_reset(), add a dummy spi_nor_remove() for it that does
nothing.

The Micron MT35XU512ABA flash does not support the quad enable bit. But
instead of programming the Quad Enable Require field to 000b ("Device

JESD216 rev D makes BFPT 20 DWORDs. Update the BFPT size define to

The check for rev A or later compared the BFPT header length with the
maximum BFPT length, BFPT_DWORD_MAX. Since BFPT_DWORD_MAX was 16, and so
was the BFPT length for both rev A and B, this check worked fine. But
now, since BFPT_DWORD_MAX is 20, it means this check will also stop BFPT
parsing for rev A or B, since their length is 16.
So, instead check for BFPT_DWORD_MAX_JESD216 to stop BFPT parsing for

Sometimes the information in a flash's SFDP tables is wrong. Sometimes
some information just can't be expressed in the SFDP table. So,
introduce the fixup hooks to allow tailoring settings for a specific
flash.
Three hooks are added: default_init, post_sfdp, and post_bfpt. These
allow tweaking the flash settings at different point in the probe
sequence. Since the hooks reside in nor->info, set that value just
before the call to spi_nor_init_params().
The hooks and at what points they are executed mimics Linux's spi-nor
framework. One major difference is that Linux puts the struct
spi_nor_fixups in nor->info. This is not possible in U-Boot because the
spi-nor-ids list is shared between spi-nor-core.c and spi-nor-tiny.c.

The get_mtd_device_nm() function (code imported from Linux) simply
iterates all registered MTD devices and compares the given name with
all MTDs' names.
With SPI_FLASH_MTD enabled U-Boot registers a SPI-NOR as a MTD device
with name identical to the SPI flash chip name (from SPI ID table). Thus
for a board with multiple same SPI-NORs it registers multiple MTDs, but
all with the same name (such as "s25fl164k"). We do not want to change
this behaviour, since such a change could break existing boot scripts,
which can rely on a hardcoded name.
In order to allow somehow to uniqely select a MTD device, change
get_mtd_device_nm() function as such:
- if first character of name is '/', try interpreting it as OF path
- otherwise compare the name with MTDs name and MTDs device name.
In the following example a board has two "s25fl164k" SPI-NORs. They both
have name "s25fl164k", thus cannot be uniquely selected via this name.
With this change, the user can select the second SPI-NOR either with
"spi-nor@1" or "/soc/spi@10600/spi-nor@1".

to DM; enables hash command for all SAM boards; fixes the NAND pmecc
bit-flips correction; adds Falcon boot for sama5d3_xplained board; and
other minor adjustments.
Not correcting anything in case of empty ECC data area
is not an appropriate strategy, because an uncorrected bit-flip
in an empty sector may cause upper layers (namely UBI) fail to work
properly. Therefore the approach chosen in Linux kernel and other
u-boot mtd drivers has been adopted, where a heuristic implemented
by nand_check_erased_ecc_chunk() is used in order to detect and
correct empty sectors.

According to S26KL512S datasheet [1] and S29GL01GS datasheet [2],
the procedure to read out PPB lock bits is to send the PPB Entry,
PPB Read, Reset/ASO Exit. Currently, the code does send incorrect
PPB Entry, PPB Read and Reset/ASO Exit is completely missing.
The PPB Entry sent is implemented by sending flash_unlock_seq()
and flash_write_cmd(..., FLASH_CMD_READ_ID). This translates to
sequence 0x555:0xaa, 0x2aa:0x55, 0x555:0x90=FLASH_CMD_READ_ID.
However, both [1] and [2] specify the last byte of PPB Entry as
0xc0=AMD_CMD_SET_PPB_ENTRY instead of 0x90=FLASH_CMD_READ_ID,
that is 0x555:0xaa, 0x2aa:0x55, 0x555:0xc0=AMD_CMD_SET_PPB_ENTRY.
Since this does make sense, this patch fixes it and thus also
aligns the code in flash_get_size() with flash_real_protect().
The PPB Read returns 00h in case of Protected state and 01h in case
of Unprotected state, according to [1] Note 83 and [2] Note 17, so
invert the result. Moreover, align the arguments with similar code
in flash_real_protect().
Finally, Reset/ASO Exit command should be executed to exit the PPB
mode, so add the missing reset.

[mtd: cfi_flash: Fix CFI flash driver for 8-bit bus support] finally
fixed this 8-bit bus support. But also broke some other boards using

I spotted a different, simpler approach for this 8-bit bus support
on the barebox mailing list posted by
Oleksij Rempel <bug-track@fisher-privat.net>:
http://www.spinics.net/lists/u-boot-v2/msg14687.html
Here the commit text:
"
Many cfi chips support 16 and 8 bit modes. Most important
difference is use of so called "Q15/A-1" pin. In 16bit mode this
pin is used for data IO. In 8bit mode, it is an address input
which add one more least significant bit (LSB). In this case
we should shift all adresses by one:
For example 0xaa << 1 = 0x154
"
This patch now is a port of this barebox patch to U-Boot.
Along with the change w.r.t from barebox,
Some flash chips can support multiple bus widths, override the
interface width and limit it to the port width.

Re the points mentioned in the removal commit:
1) This kind of requirement can be achieved using existing
flash operations and flash locking API calls instead of
making a separate flash API.
Which uclass is this?
2) Technically there is no real hardware user for this API to
use in the source tree.
I do want coral (at least) to support this.
3) Having a flash operations API for simple register read bits
also make difficult to extend the flash operations.
This new patch only mentions write-protect being on or off, rather than
the actual mechanism.
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.
That sounds to me like what drivers are for. But we still need some sort
of API for it to be accessible.

The relevant changes to the already existing GD5F1GQ4UExxG support has
been determined by consulting the GigaDevice product change notice
AN-0392-10, version 1.0 from November 30, 2020.
As the overlaps are huge, variable names have been generalized
accordingly.
Apart form the lowered ECC strength (4 instead of 8 bits per 512 bytes),
the new device ID, and the extra quad IO dummy byte, no changes had to
be taken into account.
New hardware features are not supported, namely:
- Power on reset
- Unique ID
- Double transfer rate (DTR)
- Parameter page
- Random data quad IO
The inverted semantic of the "driver strength" register bits, defaulting
to 100% instead of 50% for the Q5 devices, got ignored as the driver has
never touched them anyway.
The no longer supported "read from cache during block erase"
functionality is not reflected as the current SPI NAND core does not
support it anyway.
Implementation has been tested on MediaTek MT7688 based GARDENA smart
Gateways using both, GigaDevice GD5F1GQ5UEYIG and GD5F1GQ4UBYIG.

According to the datasheets, all of these 3 types support BP(0,1,2) and
TB bits in the status register (SR), so it could reuse the flash
protection logic for ST Micro.

Provide an explicit configuration option to disable default "unlock all"

Currently when marking a block, we use spinand_erase_op() to erase
the block before writing the marker to the OOB area. Doing so without
waiting for the operation to finish can lead to the marking failing
silently and no bad block marker being written to the flash.
In fact we don't need to do an erase at all before writing the BBM.
The ECC is disabled for raw accesses to the OOB data and we don't
need to work around any issues with chips reporting ECC errors as it
is known to be the case for raw NAND.

When writing the bad block marker to the OOB area the access mode

Currently this only works because req.mode is initialized to

req.mode != MTD_OPS_AUTO_OOB.

For reading and writing the bad block markers, spinand->oobbuf is
currently used as a buffer for the marker bytes. During the
underlying read and write operations to actually get/set the content
of the OOB area, the content of spinand->oobbuf is reused and changed
by accessing it through spinand->oobbuf and/or spinand->databuf.
This is a flaw in the original design of the SPI NAND core and at the
latest from 13c15e07eedf ("mtd: spinand: Handle the case where
PROGRAM LOAD does not reset the cache") on, it results in not having
the bad block marker written at all, as the spinand->oobbuf is
cleared to 0xff after setting the marker bytes to zero.
To fix it, we now just store the two bytes for the marker on the
stack and let the read/write operations copy it from/to the page
buffer later.

The cfi-flash driver uses an open-coded version of the generic
algorithm to decode and translate multiple frames of a "reg" property.
This starts off the wrong foot by using the address-cells and size-cells
properties of *this* very node, and not of the parent. This somewhat
happened to work back when we were using a wrong default size of 2,
but broke about a year ago with commit 0ba41ce1b7 ("libfdt: return
correct value if #size-cells property is not present").
Instead of fixing the reinvented wheel, just use the generic function
that does all of this properly.

Nand writes should skip the bad blocks with "nand write" command.
In case of bad blocks with above 32-bit address, nand_block_isbad()

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

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.

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

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.

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.

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.

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.

The end_cmd field in the variables cmd_phase_addr and data_phase_addr

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

Tested-by: Marek Vasut <marex@denx.de> # On SoCFPGA Arria V
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().

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

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.

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).

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

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.

While such overflow will certainly never happen due to the numbers

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

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.

This commit improves the ->setup_data_interface() hook.
The denali_setup_data_interface() needs the frequency of clk_x
and the ratio of clk_x / clk.
The latter is currently hardcoded in the driver, like this:
#define DENALI_CLK_X_MULT 6
The IP datasheet requires that clk_x / clk be 4, 5, or 6. I just
chose 6 because it is the most defensive value, but it is not optimal.
By getting the clock rate of both "clk" and "clk_x", the driver can
compute the timing values more precisely.

provided. It is true for all upstreamed platforms.

the Denali User's Guide requires three clocks for this IP:
- clk: controller core clock
- clk_x: bus interface clock
- ecc_clk: clock at which ECC circuitry is run
This commit supports these named clocks to represent the real hardware.
For the backward compatibility, the driver still accepts a single clock
just as before. The clk_x_rate is taken from the clock driver again if
the named clock "clk_x" is available. This will happen only for future
DT, hence the existing DT files are not affected.

SPI flash based MTD devs can be registered/unregistered at any time
through the sf probe command or the spi_flash_free() function.
This commit does not try to fix the root cause as it would probably
require rewriting most of the code and have an mtd_info object
instance per spi_flash object (not to mention that the the spi-flash
layer is likely to be replaced by a spi-nor layer ported from Linux).
Instead, we try to be as safe as can be by checking the code returned
by del_mtd_device() and complain loudly when there's nothing we can
do about the deregistration failure. When that happens we also reset
sf_mtd_info.priv to NULL, and check for NULL pointer in the mtd hooks
so that -ENODEV is returned instead of hitting a NULL pointer
dereference exception when the MTD instance is later accessed by a user.

MTD partition creation code is a bit tricky. It tries to figure out
when things have changed (either MTD dev list or mtdparts/mtdids vars)
and when that happens it first deletes all the partitions that had been
previously created and then creates the new ones based on the new
mtdparts/mtdids values.
But before deleting the old partitions, it ensures that none of the
currently registered parts are being used and bails out when that's
not the case. So, we end up in a situation where, if at least one MTD
dev has one of its partitions used by someone (UBI for instance), the
partitions update logic no longer works for other devs.
Rework the code to relax the logic and allow updates of MTD parts on
devices that are not being used (we still refuse to updates parts on
devices who have at least one of their partitions used by someone).

The initial layout for such NAND chips was the following:
+----------------------------------------------------------------------------+
| 1024 (data) | 30 (ECC) | 1024 (data) | 30 (ECC) | 32 (free OOB) | 30 (ECC) |
+----------------------------------------------------------------------------+
This layout has a weakness: reading empty pages trigger ECC errors
(this is expected), but the hardware ECC engine tries to correct the
data anyway and creates itself bitflips, hence bitflips are detected
in erased pages while actually there are none in the NAND chip.
Two solutions have been found at the same time. One was to enlarge the
free OOB area to 64 bytes, changing the layout to be:
+----------------------------------------------------------------------------+
| 1024 (data) | 30 (ECC) | 1024 (data) | 30 (ECC) | 64 (free OOB) | 30 (ECC) |
+----------------------------------------------------------------------------+
^^
The very big drawbacks of this solution are:
1/ It prevents booting from NAND.
2/ The current Linux driver (marvell_nand) does not have such problem
because it already re-reads possible empty pages in raw mode before
checking for bitflips. Using different layouts in U-Boot and Linux
would simply not work.
As this driver does support raw reads now and uses it to check for
empty pages, let's forget about this broken hack and return to the
initial layout with only 32 free OOB bytes.
