cb052d7712 riscv: qemu: spl: Fix booting Linux kernel with OpenSBI 1.0+
Since OpenSBI commit bf3ef53bb7f5 ("firmware: Enable FW_PIC by default"),
OpenSBI runs directly at the load address without any code movement.
This causes the SPL version of QEMU 'virt' U-Boot does not boot Linux
kernel anymore. In that case, OpenSBI is loaded and runs at 0x81000000,
and it creates a 512KiB PMP window from that address. When booting
the Linux kernel, moving kernel to its linking address 0x80200000
overlaps the PMP window, and a PMP access failure is raised.

Update SPL_OPENSBI_LOAD_ADDR to load OpenSBI to a safe address.

The riscv32 toolchain for GCC-12 provided by kernel.org contains libgcc.a

As U-Boot actually does not use floating point at all this should not

892759f5a0 Nokia RX-51: Fix compilation with non-zero CONFIG_SYS_TEXT_BASE
For some unknown reason GNU assembler version 2.31.1 (arm-linux-gnueabi-as
from Debian Buster) cannot compile following code from located in file
board/nokia/rx51/lowlevel_init.S:

  kernoffs:
    .word  KERNEL_OFFSET - (. - CONFIG_SYS_TEXT_BASE)

when CONFIG_SYS_TEXT_BASE is set to 0x80008000. It throws strange compile
error which is even without line number:

    AS      board/nokia/rx51/lowlevel_init.o
  {standard input}: Assembler messages:
  {standard input}: Error: attempt to get value of unresolved symbol `L0'
  make[2]: *** [scripts/Makefile.build:293: board/nokia/rx51/lowlevel_init.o] Error 1

I have no idea about this error and my experiments showed that ARM GNU
assembler is happy with negation of that number. So changing code to:

  kernoffs:
    .word  . - CONFIG_SYS_TEXT_BASE - KERNEL_OFFSET

and then replacing mathematical addition by substraction of "kernoffs"
value (so calculation of address does not change) compiles assembler file
without any error now.

There should be not any functional change.

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.

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.
