Hi Stefan,
this is v2 of series adding support for new board revision of Turris
Omnia.
See v1 at
https://patchwork.ozlabs.org/project/uboot/cover/20240304152148.3847-1-kabel@kernel.org/
Changes since v1:
- MCU firmware features can be 32-bit wide, updated the code to support
reading 32 bits of features (both in board driver and in gpio driver)
- gpio driver now moved to misc, since it handles more functionality
(rng, sysreset)
- mvebu system-controller driver expanded to also support UCLASS_SYSRESET,
configurable by config option
- LTO enabled by default for Turris Omnia, otherwise it won't fit into
the space reserved for U-Boot with these changes
- enabled the poweroff command (via sysreset) in defconfig (new MCU
firmware can power off the board voltage regulators)
- enabled the rng command in defconfig

U-Boot builds for Turris Omnia are approaching the limit of 0xf0000
bytes, which is the size of the U-Boot partition on Omnia.
Enable LTO to get more size optimized binaries.

Add header containing all MCU command definitions and use it in board
code and in MCU driver.

Since commit 8cd4bf7dc9ba ("turris: Use checkboard() instead of
show_board_info()") the model is show two times during boot:
Model: Turris Omnia
Model: Turris Omnia
This is because the common function show_board_info() shows it, and
Turris' checkboard() also does.
Remove the second print.
Fixes: 8cd4bf7dc9ba ("turris: Use checkboard() instead of show_board_info()")

Refactor MCU status word and MCU firmware features reading to make it
simpler to use.
Try reading 32 bits of features, if that fails, read 16 bits. Older MCU
firmware supports only 16-bit wide features, and if more bytes are read,
either 0xff is sent or I2C transaction fails. Handle both cases.

Implement reading board serial number, first MAC address and board
version from MCU. MCU supports board information if the FEAT_BOARD_INFO
feature bit is set in MCU features.
Prefer getting board information from MCU if supported, fallback to
Atmel SHA chip.

If the FEAT_CRYPTO feature bit is present in MCU features, the board
crypto is implemented by MCU and the Atmel SHA chip is not present.
Disable Atmel SHA device-tree node in that case.

Commit 35e29e89a386 ("arm: mvebu: Implement simple mvebu-reset driver
for enabling/disabling PCIe ports") made it so that the mvebu reset
driver for enabling/disabling PCIe ports is build if CONFIG_DM_RESET is
enabled. This is because PCI_MVEBU depends on DM_RESET.
But the driver should not be built for SPL. Indeed the PCI_MVEBU driver
is not supported in SPL now, and so the mvebu-reset driver is not needed.

The system-controller driver for 32-bit Armada is currently registered
as UCLASS_RESET, since it only provides enabling/disabling PCIe ports.
Rework it as UCLASS_SYSCON and bind mvebu-reset as a child device.

The mvebu-reset driver is only needed by the mvebu PCIe driver, but
currently it is automatically selected if DM_RESET is enabled. Add the
condition of PCI_MVEBU also being enabled for mvebu-reset to be
selected.

Add support for system power off via UCLASS_SYSRESET. Newer versions of
Turris Omnia MCU firmware can power off the board (MCU will disable
almost all voltage regulators and go into low power mode).
Move the MCU driver into drivers/misc and register it under UCLASS_MISC.
The sysreset and gpio device are bound as child devices of the MCU device.

Abort
instead of
Reading RNG failed
if the error number is -EINTR.

Add support for true random number generator provided by the MCU on
Turris Omnia. The MCU firmware supports TRNG if the FEAT_TRNG bit is set
in features. In that case we bind the rng driver.

It is unclear what would be the user benefit.
'Abort' relates to a user pressing CTRL-C?
