- Revert "Use max-frequency from device tree with default handling"
- Select CRC16 MMC_SPI_CRC_ON
- Add 1ms delay with 1ms margin after mmc power on to follow spec
The change to use dev_read_u32_default() with a default value of 0
causes regression for host controller drivers that hardcode f_max
before calling mmc_of_parse().
When the "max-frequency" property is not specified in the device tree,
dev_read_u32_default() returns 0, which overwrites the previously
configured f_max value set by the driver. This effectively resets
the maximum frequency to 0, breaking MMC functionality for those
controllers.
Revert to the original dev_read_u32() behavior which only updates
cfg->f_max when the "max-frequency" property is explicitly present
in the device tree, preserving driver-configured values otherwise.

usb: dwc3-generic: allow fallback of dr_mode property to "otg"
Documentation [1] states that the default value of the dr_mode property
is "otg". It also isn't marked a mandatory node, so it may or may not be
set. So, accordingly if dr_mode is not mentioned in the devicetree node,
OTG mode must be assumed.
In this driver however, this case is not handled. If dr_mode is not
mentioned, USB_DR_MODE_UNKNOWN is set. The logic implemented raises an
error, instead of falling back to USB_DR_MODE_OTG. Correct this to
conform to the specification.

This does a few things. First, we introduce a Kconfig option

gardena-smart-gateway-mt7688. This is not critical at the start, but is
as we move forward. Next, we move all the way from version 9.20 of the
LZMA SDK to version 25.01. The few deviations from upstream are the
changes we've already made to the files and are documented in our

unchanged from upstream, but provide no direct value to the project.
Instead, have the help text for LZMA note that this comes from the LZMA
SDK.
Next, we move our code up to the current release, 25.01. There are a
number of new header files, and some performance improvements made to
the code, at the cost of between 2 to 3 kilobytes in binary size. As
there is now a Kconfig option to disable this and retain similar speed
to what we have currently, the default option is to make this trade-off.
Our changes to the code around calling schedule() to avoid the watchdog

Enable OF_UPSTREAM for i.MX8ULP EVK so that devicetree imported from
Linux kernel release can be used.
If mailbox@29220000 is enabled, gd->arch.ele_dev will be set to this
device for communication with ELE firmware. This is incorrect because
mu@27020000 is the MU used for communication with the ELE firmware. To
prevent misconfiguration, disable mailbox@29220000.
The driver model for watchdog timer is not enabled yet, so disable wdog3
temporarily.

imx8ulp_evk: Move environment variables to .env file
Add board-specific environment variables to imx8ulp_evk.env for better
maintainability. Define bsp_bootcmd in the environment to resolve the
runtime error: "bsp_bootcmd" not defined.

imx8ulp_evk: Convert to standard boot
Replace CONFIG_DISTRO_DEFAULTS with CONFIG_BOOTSTD_FULL to enable the
standard boot framework and use standard boot on i.MX8ULP.
Update CONFIG_BOOTCOMMAND to run bootflow scan before falling back to
board-specific bootcmd, and remove legacy distro boot environment from
imx8ulp_evk.h since bootstd now handles boot targets.
Without the patch a splash screen displays with aliasing-like jagged edges.

boot: Warn users about fdt_high=~0 usage
In case the 'fdt_high' environment variable is set to ~0, warn users
about the dangers of the fdt_high usage. This will hopefully lead to
removal of most of the fdt_high ~0 usage over time.

i2c: Avoid calling dev_read_*() if CONFIG_OF_PLATDATA=y
If CONFIG_OF_PLATDATA=y , then the udevice has no valid OF node associated
with it and ofnode_valid(node) evaluates to 0. The dev_read_u32_default()
call ultimately reaches ofnode_read_u32_index() which invokes fdt_getprop()
and passes result of ofnode_to_offset(node) as an offset parameter into it.
The ofnode_to_offset(node) returns -1 for invalid node, which leads to an
fdt_getprop(..., -1, ...) invocation, which will crash sandbox with SIGSEGV
because libfdt can not handle negative node offsets without full tree check,
which U-Boot inhibits to keep size lower.
Since i2c_child_post_bind() already calls dev_has_ofnode(dev), reuse the
same call and assign i2c->speed_hz = I2C_SPEED_STANDARD_RATE in case the
device has no valid node associated with it, and do not call any of the
dev_read_*() functions for devices without valid nodes.
