2544f47078 mtd: cfi: Fix checking status register feature
Commit 72443c7f7d ("mtd: cfi: Add support for status register
polling") added a feature check to determine if status register
is available for certain flash chips. The "lower software bits"
register used to determine this feature is not backward compati-
ble. Older flash chips without this feature has reserved value
0xff. Instead of checking "lower software bits" register, use
CFI primary vendor-specific extended query. Since CFI version
1.4, software features can be read from offset 0x53 according to
document AN201168 from Cypress.

6408917821 sunxi: video: HDMI: split VSYNC and HSYNC polarity settings
These are actually different bits, and since some monitors (Benq BL2420PT)
have modes with different HSYNC and VSYNC polarity, we should set them
independently

Tested on Pine64-LTS with Benq BL2420PT monitor.

The capabilities have default values which doesn't reflect the reality
when it concerns the base clock and the mul value. Use a fixe rate
for the gck. 240 MHz is an arbitrary choice, it is a multiple of the
maximum SD clock frequency handle by the controller and it allows to

STM32F4 uses a different RCC variant than STM32F7. For STM32F4

are located into dckcfgr2 registers on STM32F7.
In both registers, bits CK48MSEL and SDMMC1SEL are located at

e6001371d1 mtd: nand: introduce NAND_ROW_ADDR_3 flag
Several drivers check ->chipsize to see if the third row address cycle
is needed.  Instead of embedding magic sizes such as 32MB, 128MB in
drivers, introduce a new flag NAND_ROW_ADDR_3 for clean-up.  Since
nand_scan_ident() knows well about the device, it can handle this
properly.  The flag is set if the row address bit width is greater
than 16.

Delete comments such as "One more address cycle for ..." because
intention is now clear enough from the code.

470c29d1c2 mtd: nand: add generic helpers to check, match, maximize ECC settings
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.

One of these constraints is that the CE line has go high after a reset

Rework the nand_reset() function and all the call sites to make sure the
CE line is asserted and released when required.

27c4792cd2 mtd: nand: automate NAND timings selection
The NAND framework provides several helpers to query timing modes supported
by a NAND chip, but this implies that all NAND controller drivers have
to implement the same timings selection dance. Also currently NAND
devices can be resetted at arbitrary places which also resets the timing
for ONFI chips to timing mode 0.

Provide a common logic to select the best timings based on ONFI or
->onfi_timing_mode_default information. Hook this into nand_reset()
to make sure the new timing is applied each time during a reset.

NAND controller willing to support timings adjustment should just
implement the ->setup_data_interface() method.

19d30ded88 mtd: nand: Add an option to maximize the ECC strength
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.

b12907f279 serial: nulldev: Implement "pending" function to fix tstc return "true"
In U-boot, serial_tstc was use to determine is there have a character in
serial console that pending for read. If there is no "pending" function
implemented in serial driver, the serial-uclass will return "true(1)"
to indicate there have a character pending to read.

Thus, read a character from nulldev serial will result in continuous
getting -EAGAIN return which might lead system to hang.

This commit is to fix a bug in nulldev serial which implement "pending"
function in nulldev serial to always indicate there is no character in
console that pending for read.

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

bcfb365375 mmc: fsl_esdhc: Fix PIO timeout
The following error has been observed on i.MX25 with a high-speed SDSC
card:
    Data Write Failed in PIO Mode.

It was caused by the timeout set on PRSSTAT.BWEN, which was triggered
because this bit takes 15 ms to be set after writing the first block to
DATPORT with this card. Without this timeout, all the blocks are
properly written.

This timeout was implemented by decrementing a variable, so it was
depending on the CPU frequency. Fix this issue by setting this timeout
to a long enough absolute duration (500 ms).

ab20107468 spi: ich: Lock down controller settings if required
Some Intel FSP (like Braswell) does SPI lock-down during the call
to fsp_notify(INIT_PHASE_BOOT). But before SPI lock-down is done,
it's bootloader's responsibility to configure the SPI controller's
opcode registers properly otherwise SPI controller driver doesn't
know how to communicate with the SPI flash device.

Rather than passively doing the opcode configuration, let's add a
simple DTS property "intel,spi-lock-down" and let the driver call
the opcode configuration function if required by such FSP.

a722359de4 SPL: SPI: select SPL_SPI_FLASH_SUPPORT on SPL_SPI_SUNXI
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).

166cae20dd mtd: replace MTDDEBUG() with pr_debug()
In old days, the MTD subsystem in Linux had debug facility like
DEBUG(MTD_DEBUG_LEVEL1, ...).

They were all replaced with pr_debug() until Linux 3.2.  See Linux
commit 289c05222172 ("mtd: replace DEBUG() with pr_debug()").

U-Boot still uses similar macros.  Covert all of them for easier sync.

Done with the help of Coccinelle.

b2915ba25e drivers: pci: imx: fix imx_pcie_remove function
We have at least a minor count of boards, that failed to re-initialize
PCI express in the Linux kernel. Typical failure rate is 20% on affected
boards. This is mitigated by commit 6ecbe13756 ("drivers: pci: imx:
add imx_pcie_remove function").

However, at least on some i.MX6 custom boards, when calling
assert_core_reset() as part of the first-time PCIe init, read access
to PCIE_PL_PFLR simply hangs. Surround this readl() with
imx_pcie_fix_dabt_handler() does not help. For this reason, the forced
LTSSM detection is only used on the second assert_core_reset() that is
called shorly before starting the Linux kernel.

Note that this changes __raw_writel et al. to writel. AFAICT this is
no problem because:

- The Linux driver for the same hardware uses the non-__raw variants as
  well (via pci_generic_config_write()).
- This driver seems to be used only on MIPS so far, where the __raw and

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>

b44b30260f printk: collect printk stuff into <linux/printk.h> with loglevel support
When we import code from Linux, with regular re-sync planned, we want
to use printk() and pr_*().  U-Boot does not support them in a clean
way.  So, people end up with local macros, or compat headers here and
there, then we occasionally see build errors of definition conflicts.

We have include/linux/compat.h, but putting all sorts of unrelated
things into a single header is just a temporal workaround.  Hence this
patch, to find the best home for all printk variants.  If you want to
use printk() and friends, please include <linux/printk.h>.  This header
is self-contained, and pulls in only a few headers.

When I was testing this clean-up, I noticed the image size exceeded
its platform limit on some boards.  This is because all pr_*() that
were previously defined as no-op in include/linux/mtd/mtd.h (unless
CONFIG_MTD_DEBUG is set), are now enabled.

To make such boards happy, this commit also implements CONFIG_LOGLEVEL.
The concept is similar to the kernel parameter "loglevel".  (Actually,
the Kconfig help message was taken from kernel-paremeter.txt of Linux)
Messages with a loglevel smaller than console loglevel will be printed.

The difference is the loglevel is build-time determined.  To save the
image size, lower priority pr_*() are compiled out.  I set the default
of CONFIG_LOGLEVEL to 6, i.e. pr_notice and higher priority messages
are compiled in.

I adjusted CONFIG_LOGLEVEL to avoid build error for some boards.

d4efefe32e dm: usb: Fix broken usb_stop()
At present we only do device_remove() during usb stop. The DM API
device_remove() only marks the device state as inactivated, but
still keeps its USB topology (eg: parent, children, etc) in the DM
device structure. There is no issue if we only start USB subsystem
once and never stop it. But a big issue occurs when we do 'usb stop'
and 'usb start' multiple times.

Strange things may be observed with current implementation, like:
- the enumeration may report only 1 mass storage device is detected,
  but the total number of USB devices is correct.
- USB keyboard does not work anymore after a bunch of 'usb reset'
  even if 'usb tree' shows it is correctly identified.
- read/write flash drive via 'fatload usb' may complain "Bad device"

In fact, every time when USB host controller starts the enumeration
process, it takes random time for each USB port to show up online,
hence each USB device may appear in a different order from previous
enumeration, and gets assigned to a totally different USB address.
As a result, we end up using a stale USB topology in the DM device
structure which still reflects the previous enumeration result, and
it may create an exact same DM device name like generic_bus_0_dev_7
that is already in the DM device structure. And since the DM device
structure is there, there is no device_bind() call to bind driver to
the device during current enumeration process, eventually creating
an inconsistent software representation of the hardware topology, a
non-working USB subsystem.

The fix is to clear the unused USB topology in the usb_stop(), by
calling device_unbind() on each controller's root hub device, and
the unbinding will unbind all of its children automatically.

For Sandbox, we need scan the device tree each time when we start
the USB stack, in order to re-create the emulated USB devices and
bind drivers for them before we actually do the driver probe.

84aa8536f0 usb: sandbox: Fix emulator device select logic in usb_emul_find_devnum()
Current emulator select logic in usb_emul_find_devnum() is to test
the USB address. The USB address of the device being enumerated is
initialized to zero at the beginning of the enumeration process in
usb_setup_device(). At this point, the saved USB address in the
platform data has not been assigned to any valid USB address either.
This means: the logic will select an emulator device according to
its sequence of declaring order in the device tree. Take test.dts
for example, flash-stick@0 will be selected before flash-stick@1.
But unfortunately such logic is wrong.

In fact USB devices show up in a random order during the enumeration
which means usb_emul_find_devnum() may be called on port 3 for keyb@3
before on port 0 for flash-stick@0.

To fix this, we introduce a new emulator uclass specific platdata
to store the USB device's port number on its parent hub, and update
the logic to test the port number instead.

3d3108d459 mmc: sdhci-cadence: set timing mode register depending on frequency
The MMC framework in U-Boot does not support a systematic API for
timing switch like mmc_set_timing() in Linux.

U-Boot just provides a hook to change the clock frequency via
mmc_set_clock().  It is up to drivers if additional register
settings are needed.

This driver needs to set a correct timing mode into a register when
it migrates to a different speed mode.  Only increasing clock frequency
could result in setup/hold timing violation.

The timing mode should be decided by checking MMC_TIMING_* like
drivers/mmc/host/sdhci-cadence.c in Linux, but "timing" is not
supported by U-Boot for now.  Just use mmc->clock to decide the
timing mode.

 _ Full compliance with SD memory card specifications version 4.1.
   (SDR104 SDMMC_CK speed limited to maximum allowed IO speed,
    SPI mode and UHS-II mode not supported).
 _ Full compliance with SDIO card specification version 4.0.
   Card support for two different databus modes: 1-bit (default)
   and 4-bit. (SDR104 SDMMC_CK speed limited to maximum allowed IO
   speed, SPI mode and UHS-II mode not supported).
 _ Data transfer up to 208 Mbyte/s for the 8 bit mode.
   (depending maximum allowed IO speed).
 _ Data and command output enable signals to control external
   bidirectional drivers.

ca1ac16da0 sf: bar: Clean BA24 Bank Address Register bit after read/write/erase operation
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
sf probe; sf read 0x11000000 0x1200000 0x800000; reset

For the time being (i.e. until regmap_init_mem_platdata works for the
64bit case), we won't use regmap_init_mem_platdata here and simply
access of_plat.reg[] directly.

cc7ce94e02 rockchip: timer: implement timer_get_boot_us
To make the Rockchip DM timer driver useful for the timing of
bootstages, we need a few enhancements:
 - This implements timer_get_boot_us.
 - This avoids reinitialising the timer, if it has already been
   set up (e.g. by our TPL and SPL stages). Now, we have a single
   timebase ticking from TPL through the full U-Boot.
 - This adds support for reading the timer even before the
   device-model is ready: we find the timer via /chosen/tick-timer,
   then read its address and clock-frequency, and finally read the
   timeval directly).

b61e8b0c9e dm: timer: Convert to livetree
This updates dm_timer_init to support a live tree and deals with
some fallout (i.e. the need to restructure the code such, that we
don't need multiple discontinuous #if CONFIG_IS_ENABLED blocks).

6c71b6f454 mtd: nand: denali: allow to override corrupted revision register
The Denali IP does not update the revision register properly.
Allow to override it with SoC data associated with compatible.

Linux had already finished big surgery of this driver, but I need
to prepare the NAND core before the full sync of the driver.
For now, I am fixing the most fatal problem on UniPhier platform.
