ec571cd4e2 net: phy: ncsi: depend on NET
PHY_NCSI enables drivers/net/phy/ncsi.c which calls net_loop() and
net_set_timeout_handler(). That's the legacy NET stack (as opposed to
NET_LWIP). Therefore add the dependency to Kconfig.

0c2d7ad3e0 buildman/toolchain.py: do not set CROSS_COMPILE for sandbox
When building for sandbox, self.cross is empty.

In MakeEnvironment(), CROSS_COMPILE is defined to be self.cross (with
or without a full path), optionally prefixed by the toolchain wrapper
defined in ~/.buildman. This is fine when self.cross is not empty, but
it doesn't make sense when it is:
- Either there is no wrapper and we end up with an empty CROSS_COMPILE
which is the same as not defining it (the host compiler will be used),
- Or there is a wrapper and CROSS_COMPILE will contain only the wrapper
which obviously is not a valid compiler, hence an error.

Test case:

 $ sudo apt install ccache
 $ grep -q toolchain-wrapper ~/.buildman || \
     printf "[toolchain-wrapper]\nwrapper = ccache\n" >>~/.buildman
 $ make mrproper
 $ ./tools/buildman/buildman sandbox_noinst
 $ ./tools/buildman/buildman sandbox_noinst
 Building current source for 1 boards (1 thread, 24 jobs per thread)
    sandbox:  +   sandbox_noinst
 +arch/sandbox/lib/reloc_sandbox_efi.c:10:15: error: operator '==' has no left operand
 +   10 | #if HOST_ARCH == HOST_ARCH_X86_64
 +      |               ^~
[...]

The GetEnvArgs function is modified too, since the VAR_CROSS_COMPILE
case has the same issue.

In tools/buildman/test.py, testGetEnvArgs is extended and
testMakeEnvironment is added. They check the 'arm' and 'sandbox'
toolchains, with and without a wrapper.

78d898eec0 Merge patch series "phycore-am62/4: Add more boot sources"
Daniel Schultz <d.schultz@phytec.de> says:

This patch stack extends the phyCORE-AM62x/AM64x U-Boot by following boot
sources:

  - Load U-Boot with USB DFU
  - Load a Linux and initramfs from OSPI/QSPI NOR flash
  - Load a Linux and rootfs from Network

Moreover, it adds required changes to the environment to boot an A/B
system with RAUC and includes some minor fixes.

c6eba28c46 spl: spl_load: fix comparison between negative error code and unsigned size
read could be a negative error value but size in spl_image is unsigned
so when they are compared read is used as if it's a unsigned value
and if it's negative it'll most likely be bigger than size and the
result will be true and _spl_load() will return 0 to the caller.

This results in the caller to _spl_load() not seeing that an error happened
as it should and continuing as if the load was completed when it might
not have been.

Check if read is negative and return it's value if it is before comparing
against size in spl_image.

52ec7b7c89 treewide: drop redundant "type string" for SYS_SOC and friends
The Kconfig symbols SYS_ARCH, SYS_CPU, SYS_SOC, SYS_VENDOR and
SYS_BOARD are defined in arch/Kconfig as having type string, and most
board files simply amend those definition with suitable

  default "foo"

or

  default "foo" if BAR

stanzas. But some also include a redundant repetition of the type.

Homogenize the code base by removing those lines.

Generated by

  find arch/*/ board -name Kconfig | xargs perl -i -g -pe 's/(config SYS_(ARCH|CPU|SOC|VENDOR|BOARD)\n)\s*string\n/\1/gs'

with the trailing slash in arch/*/ ensuring that arch/Kconfig itself
is not found.

This does not change boards which add a prompt string, e.g.

  string "Board name"

because I think those change the semantics of the symbol into being
user-settable.

e72e683e36 phy: test: Implement sandbox PHY .set_mode and DM test
Implement trivial extension to the sandbox PHY, which makes it pretend
to support selecting USB Host mode and nothing else. Any other mode is
rejected with -EINVAL. Any submode except for default submode 0 is
rejected with -EOPNOTSUPP . The implementation behaves in this trivial
way to permit easy unit testing using test which is also added in this
commit.

To run the test, use e.g. sandbox64_defconfig and run U-Boot as follows:
$ ./u-boot -Tc 'ut dm phy_setup'

a1f841a33c phy: rcar: Split init and set_mode operations
The current init operation also sets the PHY into USB host mode.
Split the mode configuration into set_mode callback instead and
implement support for device and OTG modes as well.

The OTG mode performs auto-detection and selects either host or
device mode. In case the OTG mode is configured, submode field
can be used to select full PHY (re)initialization or only mode
auto-detection. The full (re)initialization is only necessary
once, on start up.

Since the OTG mode may enable IRQ generation in the PHY, disable
that IRQ generation in the exit callback again.

USB host related, except for DM test which now behaves as a USB host
test.

Note that if the PHY driver does not implement the .set_mode callback,
generic_phy_set_mode() call returns 0 and does not error out, so this
should not break any existing systems.

d0f74bd417 buildman: Support building within a Python venv
The Python virtualenv tool sets up a few things in the environment,
putting its path first in the PATH environment variable and setting up
a sys.prefix different from the sys.base_prefix value.

At present buildman puts the toolchain path first in PATH so that it can
be found easily during the build. For sandbox this causes problems since
/usr/bin/gcc (for example) results in '/usr/bin' being prepended to the
PATH variable. As a result, the venv is partially disabled.

The result is that sandbox builds within a venv ignore the venv, e.g.
when looking for packages.

Correct this by detecting the venv and adding the toolchain path after
the venv path.
