1d9654dc43 mtd: nand: denali_dt: add a DT driver
A patch for NAND uclass support was proposed about half a year ago:
https://patchwork.ozlabs.org/patch/722282/

It was not merged and I do not see on-going work for this.

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.

294f2050c4 sf: Preserve QE bit when clearing BP# bits for Macronix flash
On some flash (like Macronix), QE (quad enable) bit is in the same
status register as BP# bits, and we need preserve its original value
during a reboot cycle as this is required by some platforms (like
Intel ICH SPI controller working under descriptor mode).

6e1eb089be mtd: nand: am335x_spl_bch: Incorporate tWB delay in nand_command function
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

adc706b2fe mtd: sunxi: Change U-Boot offset
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.

ea3f750c73 nand: sunxi: Fix modulo by zero error
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.

Rename the existing symbol to MACH_SUNXI_H3_H5 where code is shared and
let it be selected by a new shared Kconfig option.

a982bbbc1f SPI: SPL: sunxi: fix 64-bit build
Addresses passed on to readl and writel are expected to be of the same
size as a pointer. Change the parameter types of sunxi_spi0_read_data()
to make the compiler happy and allow a warning-free aarch64 compile.

706865afe5 dm: core: Add flags parameter to device_remove()
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.

203db38a94 mtd: nand: remove nand size print from nand_init function
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.

f78038dc0d mtd: nand: build MXS driver for MX7 as well
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.

e856bdcfb4 flash: complete CONFIG_SYS_NO_FLASH move with renaming
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

e160f7d430 dm: core: Replace of_offset with accessor
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
access this field through an inline function.
