fe3fddfad7 mtd: nand: do not check R/B# for CMD_SET_FEATURES in nand_command(_lp)
Set Features (0xEF) command toggles the R/B# pin after 4 sub feature
parameters are written.

Currently, nand_command(_lp) calls chip->dev_ready immediately after
the address cycle because NAND_CMD_SET_FEATURES falls into default:
label.  No wait is needed at this point.

If you see nand_onfi_set_features(), R/B# is already cared by the
chip->waitfunc call.

Read ID (0x90) command does not toggle the R/B# pin.  Without this
patch, NAND_CMD_READID falls into the default: label, then R/B# is

9b643e312d treewide: replace with error() with pr_err()
U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:

  # define __compiletime_error(message) __attribute__((error(message)))

This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux.  (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)

Let's convert error() into now treewide-available pr_err().

Done with the help of Coccinelle, excluing tools/ directory.

The semantic patch I used is as follows:

// <smpl>
@@@@
-error
+pr_err
 (...)
// </smpl>

72443c7f7d mtd: cfi: Add support for status register polling
The status register is optional in the AMD command sets, but it's
presence can be checked by reading out CFI table entry 0xc bit 0.
If the register is present, prefer using it's bit 7 to determine
if the flash is busy over reading the flash ; this is needed ie.
on Hyperflash memories.

1ec0a37e1c mtd: cfi: Zap cfi_flash_base in DM case
Embed the flash base into struct flash_info instead of having ad-hoc
static array in the code. This does not only remove static variable,
but also allows CFI-like controllers, ie. HyperFlash ones, to use most
of the CFI flash code by populating the flash_info with matching base
address.

db10809c17 Fix s25fl256s position in spi_flash_ids list
Spansion S25FS256S and S25FL256S flashes have equal JEDEC ID and ext ID.
As far as S25FL256S occures in spi_flash_ids before S25FS256S, U-Boot
incorrectly detects FS flash as FL. Thus its better to compare with
S25FS256S first.

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.

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

ff93c28265 nand: sunxi: Add options for the SPL NAND configuration
The SPL image needs to be built with a different ECC configuration than the
U-Boot binary.

Add Kconfig options with defaults to provide a value that should work for
anyone, but is still configurable if needs be.

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.
