There are a lot of zynq configurations which can be merged together and use
only one for all. The similar change has been done for ZynqMP by commit
be1b6c32d9 ("arm64: zynqmp: Use zynqmp_virt platform")

Build SPL with u-boot.img for zc706 like this.
export DEVICE_TREE=zynq-zc706 && make xilinx_zynq_virt_defconfig && make -j8
u-boot.img is generic for all boards.

3fb22bc2f8 gpio/mpc83xx_spisel_boot.c: gpio driver for SPISEL_BOOT signal
Some SoCs in the mpc83xx family, e.g. mpc8309, have a dedicated spi
chip select, SPISEL_BOOT, that is used by the boot code to boot from
flash.

This chip select will typically be used to select a SPI boot
flash. The SPISEL_BOOT signal is controlled by a single bit in the
SPI_CS register.

Implement a gpio driver for the spi chip select register. This allows a
spi driver capable of using gpios as chip select, to bind a chip select
to SPISEL_BOOT.

It may be a little odd to do this as a GPIO driver, since the signal
is neither GP or I, but it is quite convenient to present it to the
spi driver that way. The alternative it to teach mpc8xxx_spi to handle
the SPISEL_BOOT signal itself (that is how it's done in the linux
kernel, see commit 69b921acae8a)

9368bdfebd ram: stm32mp1: the property st, phy-cal becomes optional
This parameter "st,phy-cal" becomes optional and when it is
absent the built-in PHY calibration is done.

It is the case in the helper dtsi file "stm32mp15-ddr.dtsi"
except if DDR_PHY_CAL_SKIP is defined.

This patch also impact the ddr interactive mode
- the registers of the param 'phy.cal' are initialized to 0 when
  "st,phy-cal" is not present in device tree (default behavior when
  DDR_PHY_CAL_SKIP is not activated)
- the info 'cal' field can be use to change the calibration behavior
  - cal=1 => use param phy.cal to initialize the PHY, built-in training
             is skipped
  - cal=0 => param phy.cal is absent, built-in training is used (default)

compatible:
- STM32MP157: Dual Cortex-A7 cores, Cortex-M4 core @ 209 MHz,
              3D GPU, DSI display interface and CAN FD
- STM32MP153: Dual Cortex-A7 cores, Cortex-M4 core @ 209 MHz
              and CAN FD
- STM32MP151: Single Cortex-A7 core, Cortex-M4 core @ 209 MHz

Each line comes with a security option (cryptography & secure boot)
& a Cortex-A frequency option :

- A : Cortex-A7 @ 650 MHz
- C : Secure Boot + HW Crypto + Cortex-A7 @ 650 MHz
- D : Cortex-A7 @ 800 MHz
- F : Secure Boot + HW Crypto + Cortex-A7 @ 800 MHz

7ae22d7278 arm: stm32mp: bsec: add permanent lock support in bsec driver
Add BSEC lock access (read / write) at 0xC0000000 offset of misc driver.
The write access only available for Trusted boot mode, based on new
SMC STM32_SMC_WRLOCK_OTP.

With the fuse command, the permanent lock status is accessed with
0x10000000 offset (0xC0000000 - 0x8000000 for OTP sense/program
divided by u32 size), for example:

Read lock status of fuse 57 (0x39)

  STM32MP> fuse sense 0 0x10000039 1

  Sensing bank 0:

  Word 0x10000039: 00000000

Set permanent lock of fuse 57 (0x39)

  STM32MP> fuse prog 0 0x10000039 1

  Sensing bank 0:

  Word 0x10000039: 00000000

WARNING: the OTP lock is updated only after reboot

WARING: Programming lock or fuses is an irreversible operation!

ba6fb2f6ac dm: i2c-gpio: add support for clock stretching
This adds support for clock stretching to the i2c-gpio driver. This is
accomplished by switching the GPIO used for the SCL line to an input
when it should be driven high, and polling on the SCL line value until
it goes high (indicating that the I2C slave is no longer pulling it
low).

This is enabled by default; for gpios which cannot be configured as
inputs, the i2c-gpio,scl-output-only property can be used to fall back
to the previous behavior.

21e4ee3c9c doc: net: Rewrite network driver documentation
doc/README.drivers.eth seems like a good source for understanding
U-Boot's network subsystem, but is only talking about legacy network
drivers. This is particularly sad as proper documentation would help in
porting drivers over to the driver model.

Rewrite the document to describe network drivers in the new driver model
world. Most driver callbacks/methods are almost identical in their
semantic, but recv() differs in some important details.

Also keep some parts of the original text at the end, to help
understanding old drivers. Add some hints on how to port drivers over.

This also uses the opportunity to reformat the document in reST, on the
way moving it into doc/driver-model and adding it into the structure
there.

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).

e85cbe8b34 x86: Add support for ACPI general-purpose events
ACPI GPEs are used to signal interrupts from peripherals that are accessed
via ACPI. In U-Boot these are modelled as interrupts using a separate
interrupt controller. Configuration is via the device tree.

Add a simple driver for this.

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.
