285edfd782 mmc: fsl_esdhc: remove 1ms sleep in esdhc_send_cmd_common()
Since the beginning of this driver which was initially for the MPC8379
and MPC8536 SoCs, there is this spurious 1ms delay. According to the
comment it should actually be only 8 clock cycles. Esp. during EFI block
transfers, this 1ms add up to a significant delay and slows down EFI
boot.

I couldn't find any mention in the MPC8536 that there should be a delay
of 8 clock cycles between commands. The SD card specification mentions that
the clock has to be left enabled for 8 cycles after a command or
response. But I don't see how this delay will help with this.

Go ahead and just remove it. If there will ever be any regression we can
introduce a compile time flag, but for now I'd like to keep it simple.

In the split off imx driver this delay was also removed in commit
9098682200 ("mmc: fsl_esdhc_imx: remove the 1ms delay before sending
command").

5df1ee4594 arm: mvebu : sata_mv should probe all ports
While a board could have multiple SATA ports, some of the ports might
not have a disk attached to them. So while probing for disks,
sata_mv_probe() should continue probing all ports, and skip one with
no disk attached.

Tests with:

- Seagate Goflex Net (Marvell Kirkwood 88F6281) out-of-tree u-boot.
- Zyxel NSA325 (Marvell Kirkwood 88F6282 out-of-tree u-boot.

Observation:

If a board has 2 or more SATA ports, and there is only one disk
attached to one of the ports, sata_mv_probe() does not return
a successful probe status. And if only one disk is attached to the
2nd port (i.e. port 1), it is not probed at all.

Patch Description:

Let sata_mv_probe() continues probing all ports, even if there
is error in probing a given port, and then return a successful
status if there is at least one port was probed successfully.

d9ac6e28af arm: a37xx: pci: Implement re-issuing config requests on CRS response
According to PCIe base specification, if CRS Software Visibility is not
enabled, the Root Complex must re-issue the Configuration Request as a new
Request.

Normally this part of Root Complex is implemented in hardware but aardvark
is somehow special and does not implement it in hardware and expect that
handling of config requests are fully implemented in software.

This re-issuing functionality is required also because U-Boot does not
support CRS Software Visibility feature and therefore expects that Root
Complex re-issues requests as is specified in PCIe base specification.

Retry / re-issue config request up to the PIO_MAX_RETRIES, to prevent
infinite loop. After retry count exceed PIO_MAX_RETRIES, returns failure.

92055e138f image: Drop if/elseif hash selection in calculate_hash()
calculate_hash() would try to select the appropriate hashing function
by a if/elseif contruct. But that is exactly why hash_lookup_algo()
exists, so use it instead.

This does mean that we now have to 'select HASH' to make sure we get
the hash_lookup_algo() symbol. However, the change makes sense because
even basic FITs will have to deal with "hash" nodes.

My only concern is that the 'select SPL_HASH' might cause some
platform to grow above its SPL size allowance

14c251ffe1 power: Add a POWER config

It is better to have all driver directories included by drivers/Makefile

Kconfig for U-Boot proper, so add one.

Update the pmic.h header file so that it defines the old pmic struct
always, when driver model is not in use. That will avoid build errors
for boards which enable POWER but not DM_PMIC.

Enable this option always. That seems strange at first sight, but it
actually but mimics the current Makefile behaviour. Once we can drop the
old PMICs it should be easy enough to rename DM_PMIC to POWWER, or
something similar.

However, in ds1307_rtc_reset the register writes assume that the chip

the control register. While this applies correctly to the DS1307, on a
DS1340 the control register doesn't contain those bits (instead, the
register is used for clock calibration). By writing these bits the
clock calibration will be changed and the chip can become

As this symbol can either be a fixed value or the function
get_board_ddr_clk, migration is tricky.  Introduce a choice of DYNAMIC
or STATIC_DDR_CLK_FREQ.  If DYNAMIC, we continue to use the board
defined get_board_ddr_clk function.  If STATIC, set CONFIG_DDR_CLK_FREQ
to that value and now include/clock_legacy.h contains the function
prototype or defines get_board_ddr_clk() to that static value.  Update
callers to test for DYNAMIC or STATIC.

2ac8490412 watchdog: add gpio watchdog driver
A rather common kind of external watchdog circuit is one that is kept
alive by toggling a gpio. Add a driver for handling such a watchdog.

The corresponding linux driver apparently has support for some
watchdog circuits which can be disabled by tri-stating the gpio, but I
have never actually encountered such a chip in the wild; the whole
point of adding an external watchdog is usually that it is not in any
way under software control. For forward-compatibility, and to make DT
describe the hardware, the current driver only supports devices that
have the always-running property. I went a little back and forth on
whether I should fail ->probe or only ->start, and ended up deciding
->start was the right place.

The compatible string is probably a little odd as it has nothing to do
with linux per se - however, I chose that to make .dts snippets
reusable between device trees used with U-Boot and linux, and this is
the (only) compatible string that linux' corresponding driver and DT
binding accepts. I have asked whether one should/could add "wdt-gpio"
to that binding, but the answer was no:

  https://lore.kernel.org/lkml/CAL_JsqKEGaFpiFV_oAtE+S_bnHkg4qry+bhx2EDs=NSbVf_giA@mail.gmail.com/

If someone feels strongly about this, I can certainly remove the
"linux," part from the string - it probably wouldn't the only place where
one can't reuse a DT snippet as-is between linux and U-Boot.

492ee6b8d0 watchdog: wdt-uclass.c: handle all DM watchdogs in watchdog_reset()
A board can have and make use of more than one watchdog device, say
one built into the SOC and an external gpio-petted one. Having
wdt-uclass only handle the first is both a little arbitrary and
unexpected.

So change initr_watchdog() so we visit (probe) all DM watchdog
devices, and call the init_watchdog_dev helper for each.

Similarly let watchdog_reset() loop over the whole uclass - each
having their own ratelimiting metadata, and a separate "is this device
running" flag.

This gets rid of the watchdog_dev member of struct global_data.  We
do, however, still need the GD_FLG_WDT_READY set in
initr_watchdog(). This is because watchdog_reset() can get called
before DM is ready, and I don't think we can call uclass_get() that
early.

The current code just returns 0 if "getting" the first device fails -
that can of course happen because there are no devices, but it could
also happen if its ->probe call failed. In keeping with that, continue
with the handling of the remaining devices even if one fails to
probe. This is also why we cannot use uclass_probe_all().

If desired, it's possible to later add a per-device "u-boot,autostart"
boolean property, so that one can do CONFIG_WATCHDOG_AUTOSTART
per-device.

Since the watchdog_dev member of struct global_data is going away in
favor of the wdt-uclass handling all watchdog devices, prepare for
that by adding a helper to call wdt_stop() on all known devices.

If an error is encountered, still do wdt_stop() on remaining devices,
but remember and return the first error seen.

Initially, this will only be used in one single
place (board/alliedtelesis/x530/x530.c).

f1b112afbb watchdog: wdt-uclass.c: keep track of each device's running state
As a step towards handling all DM watchdogs in watchdog_reset(), use a
per-device flag to keep track of whether the device has been started
instead of a bit in gd->flags.

We will still need that bit to know whether we are past
initr_watchdog() and hence have populated gd->watchdog_dev -
incidentally, that is how it was used prior to commit 9c44ff1c5f.

b6f44082d5 mmc: zynq_sdhci: Wait till sd card detect state is stable
As per SD spec when SD host controller is reset, it takes 1000msec
to detect the card state. In case, if we enable the sd bus voltage &
card detect state is not stable, then host controller will disable
the sd bus voltage.

In case of warm/subsystem reboot, due to unstable card detect state
host controller is disabling the sd bus voltage to sd card causing
sd card timeout error. So we wait for a maximum of 1000msec to get
the card detect state stable before we enable the sd bus voltage.

This current fix is workaround for now, this needs to be analysed
further. Zynqmp platform should behave the same as Versal, but we
did not encounter this issue as of now. So we are fixing it for

Currently xilinx sdhci driver is using zynqmp_mmio_write() to set
tapdelay values and DLL resets. Continue to use this for SPL and mini
U-Boot where U-Boot will be executed at EL3 level.

Use firmware call xilinx_pm_request() using appropriate arguments to
set input/output tapdelays and also for DLL resets in regular flow(EL2).

Host driver should explicitly request DLL reset before ITAP (assert DLL)
and after OTAP (release DLL) to avoid issues in some cases. Also handle
error return where possible.

59d4230429 ddr: altera: Add SDRAM driver for Intel N5X device
The DDR subsystem in Diamond Mesa is consisted of controller, PHY,
memory reset manager and memory clock manager.

Configuration settings of controller, PHY and  memory reset manager
is come from DDR handoff data in bitstream, which contain the register
base addresses and user settings from tool.

Configuration settings of memory clock manager is come from the HPS
handoff data in bitstream, however the register base address is defined
in device tree.

The calibration is fully done in HPS, which requires IMEM and DMEM
binaries loading to PHY SRAM for running this calibration, both
IMEM and DMEM binaries are also part of bitstream, this bitstream
would be loaded to OCRAM by SDM, and configured by DDR driver.

This patch adds support for the Rockchip serial flash controller
found on the PX30 SoC. It should work for versions 3-5 of the SFC
IP, however I am only able to test it on v3.

This is adapted from the WIP SPI-MEM driver for the SFC on mainline
Linux. Note that the main difference between this and earlier versions
of the driver is that this one does not support DMA. In testing
the performance difference (performing a dual mode read on a 128Mb
chip) is negligible. DMA, if used, must also be disabled in SPL
mode when using A-TF anyway.

4cd61c43fd arm: a37xx: pci: Fix handling PIO config error responses
Returning fabricated CRS value (0xFFFF0001) by PCIe Root Complex to OS is
allowed only for 4-byte PCI_VENDOR_ID config read request and only when
CRSSVE bit in Root Port PCIe device is enabled. In all other error PCIe
Root Complex must return all-ones.

So implement this logic in pci-aardvark.c driver properly.

aardvark HW does not have Root Port PCIe device and U-Boot does not
implement emulation of this device. So expect that CRSSVE bit is set as
U-Boot can already handle CRS value for PCI_VENDOR_ID config read request.

More callers of pci_bus_read_config() function in U-Boot do not check for
return value, but check readback value. Therefore always fill readback
value in pcie_advk_read_config() function. On error fill all-ones of
correct size as it is required for PCIe Root Complex.

And also correctly propagates error from failed config write request to
return value of pcie_advk_write_config() function. Most U-Boot callers
ignores this return value, but it is a good idea to return correct value
from function.

These issues about return value of failed config read requests, including
special handling of CRS were reported by Lorenzo and Bjorn for Linux kernel
driver pci-aardvark together with quotes from PCIe r4.0 spec, see details:

7940d9628a arm: mvebu: sata_mv failed to identify HDDs during cold start
During cold start, with some HDDs, mv_sata_identify() does not populate
the ID words on the 1st ATA ID command. In fact, the first ATA ID
command will only power up the drive, and then the ATA ID command
processing is lost in the process.

Tests with:

- Seagate ST9250320AS 250GB HDD and Seagate ST4000DM004-2CV104 4TB HDD.
- Zyxel NSA310S (Kirkwood 88F6702), Marvell Dreamplug (Kirkwood 88F6281),
 Seagate GoFlex Home (Kirkwood 88F6281), Pogoplug V4 (Kirkwood 88F6192).

Observation:

- The Seagate ST9250320AS 250GB took about 3 seconds to spin up.
- The Seagate ST4000DM004-2CV104 4TB took about 8 seconds to spin up.
- mv_sata_identify() did not populate the ID words after the call to
 mv_ata_exec_ata_cmd_nondma().
- Attempt to insert a long delay of 30 seconds, ie. mdelay(30_000), after
the call to ata_wait_register() inside mv_ata_exec_ata_cmd_nondma() did
not help with the 4TB drive. The ID words were still empty after that 30s
delay.

Patch Description:

- Added a second ATA ID command in mv_sata_identify(), which will be
executed if the 1st ATA ID command did not return with valid ID words.
- Use the HDD drive capacity in the ID words as a successful indicator of
ATA ID command.
- In the scenario where a box is rebooted, the 1st ATA ID command is always
successful, so there is no extra time wasted.
- In the scenario where a box is cold started, the 1st ATA command is the
power up command. The 2nd ATA ID command alleviates the uncertainty of
how long we have to wait for the ID words to be populated by the SATA
controller.

1e9ced28f1 dm: core: Don't allow uclass use before ready
At present it is possible to call uclass_get() before driver model is
inited. In fact this happens on x86 boards which use Intel FSPv1, since
mrccache_get_region() tries to get the SPI flash device very early
during init.

This has always been undefined behaviour. Previously it generally worked,
i.e. returned an error code without crashing, because gd->uclass_root_s
is zeroed and the uclass can be added despite driver model not being
ready, due to the way lists are implemented. With the change to use a
gd->uclass_root pointer, this no-longer works. For example, it causes a
hang on minnowmax.

Fix this by adding a check that driver model is ready when uclass_get() is
called. This function is called in the process of locating any device, so
it is a good place to add the check.

This fixes booting on minnowmax.

to indicate that "fast read" opcode can be used to read data from the

If this property is not present in DT, mask out fast read in
spi_nor_init_params(). This change mirrors the same logic in

21a151a79d video: Add simple driver for ST-Ericsson MCDE with pre-configured display
The U-Boot port for ST-Ericsson Ux500 is currently only used on the
"stemmy" board, where U-Boot runs after firmware that already sets up
a boot splash screen. This means that the display is already on
and we can just continue using it for U-Boot.

Add a simple driver that simplifies this by reading the display
configuration (e.g. screen size, bpp) from the hardware registers.

It also checks the configured "source synchronization" - for some
displays (usually DSI command mode displays) we need to explicitly
trigger a software sync. This is done through the video_sync()
callback that triggers the sync and wait for completion.

5534fb4f48 arm64: a37xx: pinctrl: Correct PWM pins definitions
The PWM pins on North Bridge on Armada 37xx can be configured into PWM
or GPIO functions. When in PWM function, each pin can also be configured
to drive low on 0 and tri-state on 1 (LED mode).

The current definitions handle this by declaring two pin groups for each
pin:
- group "pwmN" with functions "pwm" and "gpio"
- group "ledN_od" ("od" for open drain) with functions "led" and "gpio"

This is semantically incorrect. The correct definition for each pin
should be one group with three functions: "pwm", "led" and "gpio".

Change the "pwmN" groups to support "led" function.

Remove "ledN_od" groups. This cannot break backwards compatibility with
older device trees: no device tree uses it since there is no PWM driver
for this SOC yet. Also "ledN_od" groups are not even documented.

Simplify the code a bit by using the common mmc_of_parse() function

Another advantage of this refactoring is that we parse more properties

936e9cd392 mmc: arm_pl180_mmci: Don't bind to all arm, primecell devices
The arm,primecell compatible is used for lots of different types
of devices, e.g. I2C, SPI, coresight, ... We really should not bind
the MMC driver to all of them.

Looking through the device trees in U-Boot there seems to be always
a second compatible string for the pl180 device, either arm,pl180
(already listed) or arm,pl18x. Add the "arm,pl18x" compatible to the
list but remove the generic "arm,primecell".

Note that on Linux these compatibles cannot be found in drivers
because AMBA/primecell devices are matched based on their peripheral ID
instead of the compatible.

This fixes the following error messages when booting the ST-Ericsson
U8500 "stemmy" board with the arm_pl180_mmci driver enabled:

a9f7be509a mmc: rpmb: Fix driver routing memory alignment with tmp buffer
Fix mmc_rpmb_route_frames() implementation to comply with most MMC
drivers that expect some alignment of MMC data frames in memory.

When called from drivers/tee/optee/rpmb.c, the address passed is not
aligned properly. OP-TEE OS inserts a 6-byte header before a raw RPMB
frame which makes RPMB data buffer not 32bit aligned. To prevent breaking
ABI with OPTEE-OS RPC memrefs, allocate a temporary buffer to copy the
data into an aligned memory.

Many RPMB drivers implicitly expect 32bit alignment of the eMMC frame
including arm_pl180_mmci.c, sandbox_mmc.c and stm32_sdmmc2.c

59e11ebf84 i2c: Create a new Kconfig for I2C
At present we have CONFIG_SPL_I2C but not CONFIG_I2C. The reason
CONFIG_I2C is not strictly necessary is that:

a) We have CONFIG_SYS_I2C_LEGACY and CONFIG_DM_I2C for the two possible
   i2c stacks
b) In U-Boot proper, we always build drivers/i2c/ regardless of the
   options

Still, it is better to have CONFIG_I2C - it makes U-Boot proper similar to
SPL/TPL, so we can (in a future commit) simplify the Makefile rules.

Enable it by default, since as above, we have separate options
(SYS_I2C_LEGACY and DM_I2C) to control whether it is 'really' enabled.

Once we have migrated I2C to driver model, we can drop SYS_I2C_LEGACY and
make DM_I2C become I2C. For now, this lets us simplify the Makefile rules.

Also we want to have a CONFIG_I2C for U-Boot proper just like we have

39b823381d phy: cadence: Add driver for Sierra PHY
Add a Sierra PHY driver with PCIe and USB support.
This driver is a port from the mainline linux driver.

The PHY has multiple lanes, which can be configured into
groups, and a generic PHY device is created for each group.

There are two resets controlling the overall PHY block, one
to enable the APB interface for programming registers, and
another to enable the PHY itself.  Additionally there are
resets for each PHY lane.

The PHY can be configured in hardware to read register
settings from ROM, or they can be written by the driver.

The sequence of operation on startup is to enable the APB
bus, write the PHY registers (if required)  for each lane
group, and then enable the PHY.  Each group of lanes
can then be individually controlled using the power_on()/
power_off() function for that generic PHY

One difference with the linux driver is that the PHY is
always reset after it is powered-on. This is because role
switching is not supported in u-boot and the cable
orientation is handled by the PHY reset.

Split arasan_zynqmp_set_tapdelay() to handle input and output tapdelays
separately. This is required to handle zero values for ITAP and OTAP
values. If we dont split, we will have to remove the if() in the
function, which makes ITAP values to be overwritten when OTAP values are
called to set and vice-versa.

Restrict tap_delay value calculated to max allowed 8 bits for ITAP and 6
bits for OTAP for ZynqMP.

affcba728b mmc: zynq_sdhci: Allow configuring zero Tap values
Allow configuring ITAP and OTAP values with zero to avoid failures in

In SD boot mode firmware configures the SD ITAP and OTAP values and

Commit b81406db51 ("arm: serial: Add debug UART capability to the

due to CONFIG_IS_ENABLED macro requires CONFIG_SPL_* prefix, the

patch fixes the bug by judging CONFIG_DEBUG_UART_PL011 explicitly.

ad7e967738 serial: serial_msm: Delay initialization to let pins stabilize
For some reason, the DragonBoard 410c aborts autoboot immediately if
U-Boot is started without LK. It looks like it picks up a single broken
character via serial and therefore believes a key was pressed to abort
autoboot.

After some debugging, it seems like adding some delay after pinctrl
setup but before UART initialization fixes the issue. It's also worth
mentioning that unlike when booting from LK, the pinctrl setup is
actually necessary when booting U-Boot without LK since UART is broken
if the pinctrl line is removed.

I suspect that reconfiguring the pins might take some time to stabilize
and if the UART controller is enabled too quickly it will pick up some
random noise. Adding a few milliseconds of delay fixes the issue and
shouldn't have any other negative side effects.

3ms seems to be the minimum delay required in my tests, use 5ms instead
just to be sure.
