Two fixes for the Amlogic Pinctrl driver :
- bad usage of clrsetbits_le32
- bad pin definition for AXG Family
Some boards feature a capacitance on LDO3's output that is too large,
causing inrush currents which as a result, shut down the AXP209. This
has been reported before, without knowing the actual cause.
A fix appeared to be done with
commit 0e6e34ac8d ("sunxi: Olimex A20 boards: Enable LDO3 and LDO4 regulators").
The description there is a bit misleading, the kernel does not hang
during AXP209 initialization, the PMIC shuts down, causing voltages to
drop and thus the whole system freezes.
While the AXP209 does have the ability to ramp up the voltage slowly, to
reduce these inrush currents, the voltage rate control (VRC) however is
not applicable when switching on the LDO3 output. Only when going from
an enabled lower voltage setting, to a higher voltage setting is the VRC
in effect.
To work around this problem, we set LDO3 to the lowest possible setting
of 0.7 V if it was not yet enabled, and then let the VRC (if enabled) do
its thing. It should be noted, that for some undocumented reason, there
is a short delay needed between setting the LDO3 voltage register and
enabling the power. One would expect that this delay ought to be just
after enabling the output power at 0.7 V, but this did not work.

The AXP209 LDO3 regulator supports voltage rate control, or can set a
slew rate.
This allows for the power to gradually rise up to the desired voltage,
instead of spiking up as fast as possible. Reason to have this can be
to reduce the inrush currents for example.
There are 3 slopes to choose from, the default, 'none' is a voltage rise
of 0.0167 V/uS, a 1.6 mV/uS and a 0.8 mV/uS voltage rise.
In ideal world (where vendors follow the recommended design guidelines)
this setting should not be enabled by default. Unless of course AXP209
crashes instead of reporting overcurrent condition as it normally should
do in this case.

In commit e5e06b65ad ("clk: Allow clock defaults to be set also

defaults in pre-reloc state was removed. While it is easy to filter
'assigned-clocks' properties for SPL using CONFIG_OF_SPL_REMOVE_PROPS,
no such mechanism exists for the pre-reloc stage of the full U-Boot.
With the default defconfig for the RK3399-Q7 (which filter the
'assigned-clocks' property for the DTS used by SPL anyway), this
caused a pause during startup of the full U-Boot stage that lasted for
almost 10s (due to the CPU not having been clocked up yet).
This reintroduces the guard from commit f4fcba5c5b ("clk: Allow
clock defaults to be set also during re-reloc state") and extends it
to only apply outside of a TPL/SPL build: i.e. clk_set_defaults will
now run in pre-reloc state for SPL, but only after reloc for the full
U-Boot.

SPI flash based MTD devs can be registered/unregistered at any time
through the sf probe command or the spi_flash_free() function.
This commit does not try to fix the root cause as it would probably
require rewriting most of the code and have an mtd_info object
instance per spi_flash object (not to mention that the the spi-flash
layer is likely to be replaced by a spi-nor layer ported from Linux).
Instead, we try to be as safe as can be by checking the code returned
by del_mtd_device() and complain loudly when there's nothing we can
do about the deregistration failure. When that happens we also reset
sf_mtd_info.priv to NULL, and check for NULL pointer in the mtd hooks
so that -ENODEV is returned instead of hitting a NULL pointer
dereference exception when the MTD instance is later accessed by a user.

spi_flash_free()).
Implement ->remove() and call spi_flash_mtd_unregister() from there.

MTD partition creation code is a bit tricky. It tries to figure out
when things have changed (either MTD dev list or mtdparts/mtdids vars)
and when that happens it first deletes all the partitions that had been
previously created and then creates the new ones based on the new
mtdparts/mtdids values.
But before deleting the old partitions, it ensures that none of the
currently registered parts are being used and bails out when that's
not the case. So, we end up in a situation where, if at least one MTD
dev has one of its partitions used by someone (UBI for instance), the
partitions update logic no longer works for other devs.
Rework the code to relax the logic and allow updates of MTD parts on
devices that are not being used (we still refuse to updates parts on
devices who have at least one of their partitions used by someone).

This patch adds a DM driver for the MPC8xx watchdog.
Basically, the watchdog is enabled by default from the start and
SYPCR register has to be writen once to set the timeout and/or
deactivate the watchdog. Once written, it cannot be written again.
It means that wdt_stop() can be called before wdt_start() to stop the
watchdog, but cannot be called if wdt_start() has been called.

Reorder the tmio_sd_set_clk_rate() function such that it handles all
of the clock requiests correctly. Specifically, before this patch,
clock request with (mmc->clock == 0 && mmc->clk_disable) could leave
the clock enabled, as the function would exit on if (!mmc->clock)
condition on top and will not handle the mmc->clk_disable at all.
Rather than band-aid fixing just that particular problem, reorder
the entire function to make it easier to understand and verify that
all the cases are covered. The function has three sections now:
First, if mmc->clock != 0, we calculate divider for the SD block.
Second, if mmc->clock != 0 and SD block clock are enabled and
current divider is not equal to the new divider, then
stop the clock and update the divider.
Third, if mmc->clk_disable is set, disable the clock, otherwise
enable the clock. This happens independently of divider
update now.

The TMIO core has a feature where it can automatically disable clock output
when the bus is not in use. While this is useful, it also interferes with
switching the bus to 1.8V and other background tasks of the SD/MMC cards,
which require clock to be enabled.
This patch respects the mmc->clk_disable and only disables the clock when
the MMC core requests it. Otherwise the clock are continuously generated
on the bus.

The USB storage driver does not compile when CONFIG_BLK is set,
but DM_USB is not set, as we're missing the DM device links for
CONFIG_BLK enabled code paths.
So far it looks like nobody fell into this trap, because no board
enabled CONFIG_BLK and CONFIG_USB_STORAGE while not enabling
CONFIG_DM_USB, but we should still reflect that dependency properly
in Kconfig so that implicit enabling of CONFIG_USB_STORAGE works.

When an operating system started via bootefi tries to reset or power off
this is done by calling the EFI runtime ResetSystem(). On most ARMv8 system
the actual reset relies on PSCI. Depending on whether the PSCI firmware
resides the hypervisor (EL2) or in the secure monitor (EL3) either an HVC
or an SMC command has to be issued.
The current implementation always uses SMC. This results in crashes on
systems where the PSCI firmware is implemented in the hypervisor, e.g.
qemu-arm64_defconfig.
The logic to decide which call is needed based on the device tree is
already implemented in the PSCI firmware driver. During the EFI runtime
the device driver model is not available. But we can minimize code
duplication by merging the EFI runtime reset and poweroff code with
the PSCI firmware driver.
As the same HVC/SMC problem is also evident for the ARMv8 do_poweroff
and reset_misc routines let's move them into the same code module.

Sandbox i2c works using emulation drivers which are currently children of
the i2c device:
rtc_0: rtc@43 {
reg = <0x43>;
compatible = "sandbox-rtc";
emul {
compatible = "sandbox,i2c-rtc";
};
};
In this case the emulation device is attached to i2c bus on address 0x43
and provides the Real-Time-Clock (RTC) functionality.
However this is not ideal, since every device on an I2C bus has a child
device. This is only really the case for sandbox, but we want to avoid
special-case code for sandbox.
A better approach seems to be to add a separate node on the bus, an
'emulation parent'. This can be given a bogus address (such as 0xff) and
hides all the emulators away. Then we can use a phandle to point from the
device to the correct emualtor, and only on sandbox. The code to find an
emulator does not interfere with normal i2c operation.
Add a new UCLASS_I2C_EMUL_PARENT uclass which allows finding an emulator
given a bus, and finding a bus given an emulator. This will be used in a
follow-on patch.

As a preparation for merging the socfpga gen5 devicetree files
from Linux, this patch makes the dwapb gpio driver work correctly
without the 'bank-name' property on the gpio-controller nodes.
This property is not present in the Linux drivers and thus is not
present in the Linux devicetrees. It is only used to access pins
via bank name.
This fallback is necessary since without it, the driver will
return an error code which will lead to an error in U-Boot
startup.
The bank names will still be added to the default board device
trees in follow-up patch, but other boards using this driver and
not including the bank name should also work with the socfpga.dtsi
without adding the bank-name property.

Comment in Linux driver says that clock needs to be doubled only
if we use DDR modes, moreover divider has to be set accordingly.
U-boot driver doesn't declare support for any DDR modes and doesn't
set internal clock divider in CLKCR, so it doubles clock
unconditionally when new mode is used.
Some cards can't handle that and as result SPL fails to load u-boot.

The initial layout for such NAND chips was the following:
+----------------------------------------------------------------------------+
| 1024 (data) | 30 (ECC) | 1024 (data) | 30 (ECC) | 32 (free OOB) | 30 (ECC) |
+----------------------------------------------------------------------------+
This layout has a weakness: reading empty pages trigger ECC errors
(this is expected), but the hardware ECC engine tries to correct the
data anyway and creates itself bitflips, hence bitflips are detected
in erased pages while actually there are none in the NAND chip.
Two solutions have been found at the same time. One was to enlarge the
free OOB area to 64 bytes, changing the layout to be:
+----------------------------------------------------------------------------+
| 1024 (data) | 30 (ECC) | 1024 (data) | 30 (ECC) | 64 (free OOB) | 30 (ECC) |
+----------------------------------------------------------------------------+
^^
The very big drawbacks of this solution are:
1/ It prevents booting from NAND.
2/ The current Linux driver (marvell_nand) does not have such problem
because it already re-reads possible empty pages in raw mode before
checking for bitflips. Using different layouts in U-Boot and Linux
would simply not work.
As this driver does support raw reads now and uses it to check for
empty pages, let's forget about this broken hack and return to the
initial layout with only 32 free OOB bytes.

This only applies on BCH path.
When an empty page is read, it triggers an uncorrectable error. While
this is expected, the ECC engine might produce itself bitflips in the
read data under certain layouts. To overcome this situation, always
re-read the entire page in raw mode and check for the whole page to be
empty.
Also report the right number of bitflips if there are any.

Raw read support is added by editing a few code sections:
->handle_data_pio() includes the ECC bytes that are not consumed
anymore by the ECC engine.
->prepare_set_command() is changed so that the ECC bytes are
requested as part of the data I/O length.
->drain_fifo() shall also avoid checking the R/B pin too often
when in raw mode.
->read_page_raw()/->read_oob_raw() are written from scratch.

When the device tree is missing a correct spi slave description below
the bus (compatible "spi-flash" or spi-max-frequency are missing),
the 'set_speed' callback can be called with 'speed' == 0 Hz.
At least with cadence qspi, this leads to a division by zero.

fallback value as is done in 'dm_spi_claim_bus') and issue a warning

The SD UHS SDR12, SDR25, SDR50, SDR104, DDR50 and MMC HS200, HS400
modes all use 1.8V signaling, while all the legacy modes use 3.3V
signaling. While there are extra modes which use 1.2V signaling,
the existing hardware does not support those.
Simplify the pinmux such that 3.3V signaling implies legacy mode
pinmux and the rest implies UHS mode pinmux. This prevents the
massive case statement from growing further. Moreover, it fixes
an edge case where during SD 1.8V switch, the bus mode is still
set to default while the signaling is already set to 1.8V, which
results in an attempt to communicate with a 1.8V card using pins
in 3.3V mode and thus communication failure.

The abort occurred in the ds24xxx_probe() because the struct w1_device

Add the power domain DM driver for i.MX8, that it depends on the DTB
power domain trees to generate the power domain provider devices. Users
need to add power domain trees with property "compatible = "nxp,imx8-pd";"
When power on a PD device, the driver will power on its ancestor PD
devices in power domain tree.
When power off a PD device, the driver will check its child PD devices
first. Only if all child PD devices are off, then power off the current PD
device. Then the driver checks sibling PD devices. If sibling PD devices
are off, then it will power off parent PD device.
There is no counter maintained in this driver, but a state to hold current
on/off state. So the request and free functions are empty.
The power domain implementation in i.MX8 DTB set the "#power-domain-cells"
to 0, so there is no ID binding with each PD device. We don't use "id"

So far the TSC timer driver supports trying hardware calibration first
and using device tree as last resort for its running frequency as the
normal timer.
However when it is used as the early timer, it only supports hardware
calibration and if it fails, the driver just panics. This introduces
a new config option to specify the early timer frequency in MHz and
it should be equal to the value described in the device tree.
Without this patch, the travis-ci testing on QEMU x86_64 target fails
each time after it finishes the 'bootefi selftest' as the test.py see
an error was emitted on the console like this:
TSC frequency is ZERO
resetting ...
### ERROR ### Please RESET the board ###
It's strange that this error is consistently seen on the travis-ci
machine, but only occasionally seen on my local machine (maybe 1 out
of 10). Since QEMU x86_64 target enables BOOTSTAGE support which uses
early timer, with this fix it should work without any failure.

In initr_bootstage() we call bootstage_mark_name() which ends up calling
timer_get_us(). This call happens before initr_dm(), which inits driver
model.
On x86 we set gd->timer to NULL in the transition from board_init_f()
to board_init_r(). See board_init_f_r() for this assignment. So U-Boot
knows there is no timer available in the period immediately after
relocation.
On x86 the timer_get_us() call is implemented as calls to get_ticks() and
get_tbclk(). Both of these call dm_timer_init() to set up the timer, if
gd->timer is NULL and the early timer is not available.
However dm_timer_init() cannot succeed before initr_dm() is called.
So it seems that on x86 if we want to use CONFIG_BOOTSTAGE we must enable
CONFIG_TIMER_EARLY. Update the Kconfig to handle this.
Note: On most architectures we can rely on the pre-relocation memory still
being available, so that gd->timer pointers to a valid timer device and
everything works correctly. Admittedly this is not strictly correct since
the timer device is set up by pre-relocation U-Boot, but normally this is
fine. On x86 the 'CAR' (cache-as-RAM) memory used by pre-relocation U-Boot
disappears in board_init_f_r() and any attempt to access it will hang.
This is the reason why we must mark the timer as invalid when we get to
board_init_f_r().

Create a binding to select a specific clock for CLK_OUT pin.
Based on commit 9708fb630d19 ("net: phy: dp83867: Add binding for
the CLK_OUT pin muxing option") of mainline linux kernel.

The DP83867 when not properly bootstrapped - especially with LED_0 pin -
can enter N/A MODE4 for "port mirroring" feature.
To provide normal operation of the PHY, one needs not only to explicitly
disable the port mirroring feature, but as well stop some IC internal
testing (which disables RGMII communication).
To do that the STRAP_STS1 (0x006E) register must be read and RESERVED bit
11 examined. When it is set, the another RESERVED bit (11) at PHYCR
(0x0010) register must be clear to disable testing mode and enable RGMII
communication.
Thorough explanation of the problem can be found at following e2e thread:
"DP83867IR: Problem with RESERVED bits in PHY Control Register (PHYCR) -
Linux driver"

This patch adds support for enabling or disabling the lane swapping
(called "port mirroring" in PHY's CFG4 register) feature of the DP83867
TI's PHY device.
One use case is when bootstrap configuration enables this feature (because
of e.g. LED_0 wrong wiring) so then one needs to disable it in software
(at u-boot/Linux).
Based on commit fc6d39c39581 ("net: phy: dp83867: Add lane swapping
support in the DP83867 TI's PHY driver") of mainline linux kernel.

At present this function uses pixels but it seems more useful for it to

This file has changed quite a bit in the last 5 years as the capabilities
of the ECs have grown. Sync it up with the copy in coreboot commit

The only change is the addition of EC_VBNV_BLOCK_SIZE_V2. This is needed
because U-Boot uses the new v2 vboot API and this is not currently fully
