622d27bc3f sunxi: OrangePi Zero 2: Enable SPI booting
The OrangePi Zero 2 board comes with 2MB of SPI flash, from which the
BROM is able to boot from. Please note that the fuse setup requires
PC5 (BOOT_SEL3) to be pulled to GND for that to actually work.

Enable the SPL code responsible for finding and loading U-Boot proper and
friends, so that u-boot-sunxi-with-spl.bin can be written into the flash.

e50ee3a8d7 sunxi: SPL SPI: Add SPI boot support for the Allwinner H616 SoC
The H616 SoC uses the same SPI IP as the H6, also shares the same clocks
and reset bits.
The only real difference is a slight change in the pin assignment: the
H6 uses PC5, the H616 PC4 instead. This makes for a small change in
our spi0_pinmux_setup() routine.

Apart from that, just extend the H6 #ifdef guards to also cover the H616,
using the shared CONFIG_SUN50I_GEN_H6 symbol.
Also use this symbol for the Kconfig dependency.

8094a4ed9d sunxi: defconfig: drop redundant definitions
When some configuration symbols were converted from header files to
Kconfig, their values were placed into *every* defconfig file.
Since we now have sensible per-SoC defaults defined in Kconfig, those
values are now redundant, and can just be removed.

177040b1eb sunxi: Kconfig: use SoC-wide values for some symbols
Some configuration symbols formerly defined in header files were
recently converted to Kconfig symbols. This moved their value definition
into *every* defconfig file, even though those values are hardly board
choices.
Use the new Kconfig option to define per-SoC default values, in just one
place, which makes the definition in each defconfig file redundant.

We refrain from setting a sunxi specific value for CONFIG_SYS_BOOTM_LEN,
so this defaults to a much better 64MB for uncompressed arm64 kernels.

ae0bf2214b vbe: Add a test for VBE device tree fixups

the requested info to corresponding subnodes of the /chosen node. Add a
pytest for this, which sets up the FIT, runs bootm and then uses a C
unit test to check that everything looks OK.

The test needs to run on sandbox_flattree since we don't support
device tree fixups on sandbox (live tree) yet. So enable BOOTMETH_VBE and
disable bootflow_system(), since EFI is not supported on
sandbox_flattree.

13819f07ea bootm: Change incorrect 'unsupported' error
At present when bootm fails, it says:

    subcommand not supported

and then prints help for the bootm command. This is not very useful, since
generally the error is related to something else, such as fixups failing.
It is quite confusing to see this in a test run.

Change the error and show the error code.

We could update the OS functions to return -ENOSYS when they do not
support the bootm subcommand. But this involves some thought since this is
arch-specific code and proper errno error codes are not always returned.
Also, with the code as is, all required subcommands are of course
supported - a problem would only come if someone added a new one or
removed support for one from an existing OS. Therefore it seems better to
leave that sort of effort for when our bootm tests are improved.

Note: v1 of this patch generated a discussion[1] about printing error
strings automatically using printf(). That is outside the scope of this
patch but will be dealt with separately.

e44d7e73fe dm: core: Switch uclass_*_device_err to use uclass_*_device_check
The _err variant iterators use the simple iterators without suffix as
basis.

However, there is no user that uclass_next_device_err for iteration,
many users of uclass_first_device_err use it to get the first and
(assumed) only device of an uclass, and a couple that use
uclass_next_device_err to get the device following a known device in the
uclass list.

While there are some truly singleton device classes in which more than
one device cannot exist these are quite rare, and most classes can have
multiple devices even if it is not the case on the SoC's EVB.

In a later patch the simple iterators will be updated to not stop on
error and return next device instead. With this in many cases the code
that expects the first device or an error if it fails to probe may get
the next device instead. Use the _check iterators as the basis of _err
iterators to preserve the old behavior.

0736f7aa3b net: eth-uclass: Do not set device on error
eth_get_dev relies on the broken behavior that returns an error but not
the device on which the error happened which gives the caller no
reasonable way to report or handle the error.

In a later patch uclass_first_device_err will be changed to return the
device on error but eth_get_dev stores the returned device pointer
directly in a global state without checking the return value. Unset the
pointer again in the error case.

9b7474d83b dm: blk: Do not use uclass_next_device_err
blk_first_device_err/blk_next_device_err uses
uclass_first_device_err/uclass_next_device_err for device iteration.

Although the function names superficially match the return value from
uclass_first_device_err/uclass_next_device_err is never used
meaningfully, and uclass_first_device/uclass_next_device works equally
well for this purpose.

In the following patch the semantic of
uclass_first_device_err/uclass_next_device_err will be changed to be
based on uclass_first_device_check/uclass_next_device_check breaking
this sole user that uses uclass_next_device_err for iteration.

1d0617bd74 dm: treewide: Use uclass_next_device_err when accessing second device
There are a couple users of uclass_next_device return value that get the
first device by other means and use uclass_next_device assuming the
following device in the uclass is related to the first one.

Use uclass_next_device_err because the return value from
uclass_next_device will be removed in a later patch.

c726fc01cf dm: treewide: Use uclass_first_device_err when accessing one device
There is a number of users that use uclass_first_device to access the
first and (assumed) only device in uclass.

Some check the return value of uclass_first_device and also that a
device was returned which is exactly what uclass_first_device_err does.

Some are not checking that a device was returned and can potentially
crash if no device exists in the uclass. Finally there is one that
returns NULL on error either way.

Convert all of these to use uclass_first_device_err instead, the return
value will be removed from uclass_first_device in a later patch.

8676ae36ae cmd: List all uclass devices regardless of probe error
There are a few commands that iterate uclass with
uclass_first_device/uclass_next_device or the _err variant.

Use the _check class iterator variant to get devices that fail to probe
as well, and print the status.

7ff12631b4 stdio: Fix class iteration in stdio_add_devices()
There is a complaint in the code that iterates keyboards that we don't
have the _check variant of class iterator but we in fact do, use it.

In the code that iterates video devices there is an attempt to print
errors but the simple iterator does not return a device when there is an
error. Use the _check variant of the iterator as well.

Also format error messages consistently.

2cb43ef1c2 usb: ether: Fix error handling in usb_ether_init
The code checks the return value from uclass_first_device as well as
that the device exists but it passes on the return value which may be
zero if there are no gadget devices. Just check that a device was
returned and return -ENODEV otherwise.

Also remove the dev variable which is not really used for anything.
