72732318a9 cmd: mdc/mwc: normalize disjoint MX_CYCLIC usage
Both CMD_MX_CYCLIC and MX_CYCLIC are in use and defined in Kconfig,
but only the non-CMD version currently does anything. This changes all
usages to prefer the CMD_MX_CYCLIC option (since it's only affecting
addition of the commands), and switches defconfigs using the non-CMD
version to use the CMD version.

4cfeb8df31 tools: imx8m_image: fix warning message
When a firmware file is missing the warning message doesn't indicate the
firmware file name because '$tmp' var doesn't exist.
Fix the warning message and while at it reduce the if/else statement.

3ce1ef5b8f mx6sxsabresd: Keep only one target
Currently there are two targets for the i.MX6SX SabreSD board:
mx6sxsabresd_defconfig and mx6sxsabresd_spl_defconfig.

This brings additional maintainance effort without a clear
advantage.

Keep only the mx6sxsabresd_defconfig one and remove
mx6sxsabresd_spl_defconfig to keep it simpler.

Also remove the SPL related code from the board file.

c0a179a7a5 gpio: Let DM_74X164 be built without CONFIG_SPL_GPIO
Since commit bcee8d6764 ("dm: gpio: Allow control of GPIO uclass in SPL")
CONFIG_DM_74X164 is no longer built for mx7dsabresd_defconfig, as
this target does not use CONFIG_SPL_GPIO.

Remove such dependency and let the the 74X164 GPIO driver be built
again.

This restores Ethernet functionality on the imx7-sdb board as the
Ethernet reset PHY comes from a GPIO driven by a 74LV595PW I/O
expander.

14d5aeff77 board: toradex: Add Verdin iMX8M Mini support
This adds initial minimal support for the Toradex Verdin iMX8M Mini Quad
2GB WB IT V1.0A module. They are now strapped to boot from eFuses which
are factory fused to properly boot from their on-module eMMC. U-Boot
supports booting from the on-module eMMC only, SDP support is disabled
for now due to missing i.MX 8M Mini USB support.

Functionality wise the following is known to be working:
- eMMC, 8-bit and 4-bit MMC/SD card slots
- Ethernet
- GPIOs
- I2C

Boot sequence is:
SPL ---> ATF (TF-A) ---> U-boot proper

ATF, U-boot proper and u-boot.dtb images are packed into a FIT image,
loaded by SPL.

The code for handing file overwrite incorrectly calculated the amount of
data to write when writing to the last non-cluster aligned chunk. Fix
this by ensuring that no more data than the 'filesize' is written to disk.
While touching min()-based calculations, change it to type-safe min_t()
function.

5e615b74e8 fat: write: fix broken write to fragmented files
The code for handing file overwrite incorrectly assumed that the file on
disk is always contiguous. This resulted in corrupting disk structure
every time when write to existing fragmented file happened. Fix this
by adding proper check for cluster discontinuity and adjust chunk size
on each partial write.

Overwritting a discontiguous test file (file0007.raw) no longer causes
corruption to file0003.raw, which's data lies between the chunks of the
test file. The amount of data written to disk is still incorrect, what
causes damage to the file (file0005.raw), which's data lies next to the

4dbc107f46 cmd: gpio: Correct do_gpio() return value
Use the correct return value in function do_gpio() and update
commands documentation with the return values from command_ret_t enum.

CMD_RET_SUCCESS is returned on command success and CMD_RET_FAILURE is
returned on command failure.

The command was returning the pin value, which caused confusion when
debugging (#define DEBUG).

H1 is a Google security chip present in recent Chromebooks, Pixel phones

This chip is used to handle TPM-like functionality and also has quite a

025543554c dm: irq: Add support for requesting interrupts
At present driver model supports the IRQ uclass but there is no way to
request a particular interrupt for a driver.

Add a mechanism, similar to clock and reset, to read the interrupts
required by a device from the device tree and to request those interrupts.

U-Boot itself does not have interrupt-driven handlers, so just provide a
means to read and clear an interrupt. This can be useful to handle
peripherals which must use an interrupt to determine when data is
available, for example.

Bring over the basic binding file as well, from Linux v5.4. Note that the
older binding is not supported in U-Boot; the newer 'special form' must be
used.

Add a simple test of the new functionality.

ba87607971 dm: irq: Add support for interrupt controller types
There can be different types of interrupt controllers in a system and some
drivers may need to distinguish between these. In general this can be
handled using the device tree by adding the interrupt information to
device nodes.

However on x86 devices we have interrupt controllers which are not tied
to any particular device and not really used in U-Boot. These still need
to be inited, so a convenient method is to give each controller a type
and allow a particular controller type to be probed.

Add support for this in sandbox along with a test.

eb8af95fc5 x86: apl: Drop the I2C config in FSP-S
This config is not actually used here and in U-Boot it seems better to set
this using the device tree for each individual controller. The monolithic
config of the FSP-S is only necessary if the FSP is actually configuring
something, but here it is not.

The FSP-S does enable/disable the various I2C ports. It might be nice to
handle this using the okay/disabled property of each port, but that can be
considered later.
