The variable cfi_flash_num_flash_banks is defined iff
CONFIG_SYS_MAX_FLASH_BANKS_DETECT is defined, but it is used
unconditionally in the function cfi_flash_init_dm. This leads to a
undefined variable compile error when CONFIG_SYS_MAX_FLASH_BANKS_DETECT
is not defined, but DM is enabled.
Fix this by always defining the cfi_flash_num_flash_banks variable.

Driver are responsible for setting up ECC parameters correctly.
Those include:
- Check if ECC parameters specified (usually by DT) are valid
- Meet the chip's ECC requirement
- Maximize ECC strength if NAND_ECC_MAXIMIZE flag is set
The logic can be generalized by factoring out common code.
This commit adds 3 helpers to the NAND framework:
nand_check_ecc_caps - Check if preset step_size and strength are valid
nand_match_ecc_req - Match the chip's requirement
nand_maximize_ecc - Maximize the ECC strength
To use the helpers above, a driver needs to provide:
- Data array of supported ECC step size and strength
- A hook that calculates ECC bytes from the combination of
step_size and strength.
By using those helpers, code duplication among drivers will be
reduced.

for ONFI chips to timing mode 0.
Provide a common logic to select the best timings based on ONFI or

The generic NAND DT bindings allows one to tweak the ECC strength and
step size to their need. It can be used to lower the ECC strength to
match a bootloader/firmware config, but might also be used to get a better
reliability.
In the latter case, the user might want to use the maximum ECC strength
without having to explicitly calculate the exact value (this value not
only depends on the OOB size, but also on the NAND controller, and can
be tricky to extract).
Add a generic 'nand-ecc-maximize' DT property and the associated
NAND_ECC_MAXIMIZE flag, to let ECC controller drivers select the best
ECC strength and step-size on their own.

Currently the chipselect used to identify the corresponding NAND chip
is stored at the controller and only set during fsl_ifc_chip_init().
This way, only the last NAND chip is working, as the previous value
of cs_nand gets overwritten.
In order to solve this issue the chipselect is computed on demand by
evaluating the bank variable. Thus, the correct chipselect for each
NAND chip operation is used.
Tested on hardware with two NAND chips connected to the IFC
controller.

The Allwinner SPI flash SPL boot support is guarded by the SPL_SPI_SUNXI
symbol. But despite its generic name, the actual only use case for this
is to provide SPI flash support to the SPL, which requires
CONFIG_SPL_SPI_FLASH_SUPPORT to be defined.
Select this symbol from the SPL_SPI_SUNXI Kconfig definition. This
avoids doing this explicitly in the defconfig, and fixes SPI booting on
the Pine64 SoPine (and -LTS version) and the OrangePi Win board (both with
SPI flash).

The content of Bank Address Register (BAR) is volatile. It is cleared
after power cycle or reset command (RESET F0h).
Some memories (like e.g. s25fl256s) use it to access memory larger than
0x1000000 (16 MiB).
The problem shows up when one:
1. Reads/writes/erases memory > 16 MiB
2. Calls "reset" u-boot command (which is not causing BAR to be cleared)
In the above scenario, the SoC ROM sends 0x000000 address to read SPL.
Unfortunately, the BA24 bit is still set and hence it receives content
from 0x1000000 (16 MiB) memory address.
As a result the SoC aborts and we hang. Only power cycle can take the
SoC out of this state.
How to reproduce/test:
sf probe; sf erase 0x1200000 0x800000; reset
sf probe; sf erase 0x1200000 0x800000; sf write 0x11000000 0x1200000 0x800000; reset

Without DM-based probing, we need to set up pinctrl etc. in an ad-hoc
way and give lots of crappy CONFIG options for base addresses and
properties, which are supposed to be specified by DT. This is painful.
This commit just provides a probe hook to retrieve "reg" from DT and
allocate private data in a DM manner. This DT driver is not essentially
a NAND driver, in fact it is (ab)using UCLASS_MISC. Once UCLASS_NAND is
supported, it would be possible to migrate to it.

Various commands to NAND flash results in the NAND flash becoming busy.
For those commands the SoC should wait until the NAND indicates it is
no longer busy before sending further commands. However, there is a delay
between the time the SoC sends its last command and when the NAND flash
sets its Ready/Busy Pin. This delay (tWB) must be respected or the SoC may
falsely assume the flash is ready when in reality it just hasn't had enough
time to indicate that it is busy.
Properly delaying by tWB is already done for nand_command/nand_command_lp
in nand_base.c including the version of it in the Linux kernel. Therefore,
this patch brings the handling of tWB delay inline to nand_base.c

The default U-Boot offset for the Allwinner SoCs was set to 32kB.
This was probably to try to maintain some compatibility with the current
image that we build for the MMC where the U-Boot binary is also located at
a 32kB offset.
However, this causes a number of issues. The first one is that it prevents
us from using a backup SPL entirely, which is troublesome in case where the
first would be corrupt (especially on MLC which have a higher number of
bitflips).
We also cannot use the original MMC image on the NAND, because we need to
prepare the SPL image to include the ECCs and randomizer settings, which
reduces the interest of setting it at that particular offset.
It also prevents us from upgrading and flashing the U-Boot and SPLs
independantly, since it's very likely that it will fall in the same erase
block.
Since that default wasn't used by any board, change it for 8MB, which will
be in an erase block of its own, all the erase blocks being multiple of
two. The highest erase block size we encountered is 4MB, which means that
in this particular setup, the first and second erase blocks will be for the
SPL and its backup, and the third for U-Boot.

When trying to autodetect the ECC and randomization configurations, the
driver starts with a randomization disabled and no seeds.
In this case, the number of seeds is obviously 0, and the randomize boolean
is set to false.
However, the logic that retrieves the seed for a given page offset will
blindly use the number of seeds, without testing if the randomization is
enabled, basically doing a modulo by 0.
As it turns out, the libgcc in the common toolchain returns 0 here, which
was our expected value in such a case, and why we would not detect it.
However, U-Boot's libgcc will for some reason return from the function
instead, resulting in an error to load the U-Boot binary in the SPL.

The Allwinner H5 is very close to the H3 SoC, but has ARMv8 cores.
To allow sharing the clocks, GPIO and driver code easily, create an
architecture agnostic MACH_SUNXI_H3_H5 Kconfig symbol.
Rename the existing symbol to MACH_SUNXI_H3_H5 where code is shared and
let it be selected by a new shared Kconfig option.

Addresses passed on to readl and writel are expected to be of the same

This patch adds the flags parameter to device_remove() and changes all
calls to this function to provide the default value of DM_REMOVE_NORMAL
for "normal" device removal.
This is in preparation for the driver specific pre-OS (e.g. DMA
cancelling) remove support.

Add nand_size() function to move the nand size print into initr_nand().
Remove nand size print from nand_init() to allow other function to call
nand_init() without printing nand size.

The i.MX7 has the same GPMI controller as i.MX6 and is covered by the MXS
driver. Tell Kconfig that we can use this driver on the MX7 platform (the MXS
driver already has the few i.MX7-specific changes needed for basic operation
and the board itself sets the pinmux correctly).
Tested on i.MX7D with the Sabre board and a NAND Flash soldered to U12.

We repeated partial moves for CONFIG_SYS_NO_FLASH, but this is
not completed. Finish this work by the tool.
During this move, let's rename it to CONFIG_MTD_NOR_FLASH.
Actually, we have more instances of "#ifndef CONFIG_SYS_NO_FLASH"
than those of "#ifdef CONFIG_SYS_NO_FLASH". Flipping the logic will
make the code more readable. Besides, negative meaning symbols do
not fit in obj-$(CONFIG_...) style Makefiles.
This commit was created as follows:
[1] Edit "default n" to "default y" in the config entry in
common/Kconfig.
[2] Run "tools/moveconfig.py -y -r HEAD SYS_NO_FLASH"
[3] Rename the instances in defconfigs by the following:
find . -path './configs/*_defconfig' | xargs sed -i \
-e '/CONFIG_SYS_NO_FLASH=y/d' \
-e 's/# CONFIG_SYS_NO_FLASH is not set/CONFIG_MTD_NOR_FLASH=y/'
[4] Change the conditionals by the following:
find . -name '*.[ch]' | xargs sed -i \
-e 's/ifndef CONFIG_SYS_NO_FLASH/ifdef CONFIG_MTD_NOR_FLASH/' \
-e 's/ifdef CONFIG_SYS_NO_FLASH/ifndef CONFIG_MTD_NOR_FLASH/' \
-e 's/!defined(CONFIG_SYS_NO_FLASH)/defined(CONFIG_MTD_NOR_FLASH)/' \
-e 's/defined(CONFIG_SYS_NO_FLASH)/!defined(CONFIG_MTD_NOR_FLASH)/'
[5] Modify the following manually
- Rename the rest of instances
- Remove the description from README
- Create the new Kconfig entry in drivers/mtd/Kconfig
- Remove the old Kconfig entry from common/Kconfig
- Remove the garbage comments from include/configs/*.h

At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to

This reverts commit c56ae7519f.
Once the 'Quad Enable' bit is cleared in their Enhanced Volatile
Configuration Register (EVCR), Micron memories expect ALL commands to use
the SPI 4-4-4 protocol. Commands using SPI 1-y-z protocols are no longer
accepted.
Within the reverted commit, the write_evcr() function is implemented using
the spi_flash_write_common(), which is a shortcut for the
[ spi_flash_cmd_write_enable(), spi_flash_cmd_write(),
spi_flash_cmd_wait_ready() ] sequence.
Since the internal state of the Micron memory has been changed when the
spi_flash_cmd_write() function completes, the later call of the
spi_flash_cmd_wait_ready() function fails.
Indeed the SPI controller driver is not aware of the SPI protocol switch.
Further patches will fix the support of Micron QSPI memories.

In spi_flash_scan, 'ret' is initialled to -1, but 'ret' is not always
used to store a return value, in that case, even when the function
succeed, an error (-1) will be returned.
Lets just return 0 if we hit the end of the function.

It is useful to name each method so that we can print out this name when
using the method. Currently this happens using a separate function. In
preparation for unifying this, add a name to each method.
The name is only available if we have libcommon support (i.e can use
printf()).
