Currently, bad patterns are only honored when executing a shell command.
Other cases, such as the initial boot-up of U-Boot or when interacting
with command output rather than gathering all output prior to the shell
prompt, do not currently look for bad patterns in console output. This
patch makes sure that bad patterns are honored everywhere.
One benefit of this change is that if U-Boot sandbox fails to start up,
the error message it emits can be caught immediately, rather than relying
on a (long) timeout when waiting for the expected signon message and/or
command prompt.

When pytest generates the name for parametrized tests, simple parameter
values (ints, strings) get used directly, but more complex values such
as dicts are not handled. This yields test names such as:
dfu[env__usb_dev_port0-env__dfu_config0]
dfu[env__usb_dev_port0-env__dfu_config1]
Add some code to extract a custom fixture ID from the fixture values, so
that we end up with meaningful names such as:
dfu[micro_b-emmc]
dfu[devport2-ram]
If the boardenv file doesn't define custom names, the code falls back to
the old algorithm.

The existing net test executes a list of commands supplied by boardenv
variable env__net_pre_commands. The idea was that boardenv would know
whether the Ethernet device was attached to USB, PCI, ... and hence was
the best place to put any commands required to probe the device.
However, this approach doesn't scale well when attempting to use a single
boardenv across multiple branches of U-Boot, some of which require "pci
enum" to enumerate PCI and others of which don't, or don't /yet/ simply
because various upstream changes haven't been merged down.
This patch updates the test to require that the boardenv state which HW
features are required for Ethernet to work, and lets the test itself map
that knowledge to the set of commands to execute. Since this mapping is
part of the test script, which is part of the U-Boot code/branch, this
approach is more scalable. It also feels cleaner, since again boardenv
is only providing data, rather than test logic.

Currently, the distro boot commands always enumerate USB devices before
performing network operations. However, depending on the board and end-
user configuration, network devices may not be attached to USB, and so
enumerating USB may not be necessary. Enhance the scripts to make this
step optional, so that the user can decrease boot time if they don't
need USB.
This change is performed by moving the "usb start" invocation into a
standalone variable. If the user desires, they can replace that
variable's value with some no-op command such as "true" instead.
Booting from a USB storage device always needs to enumerate USB devices,
so this action is still hard-coded.

With CONFIG_DM_PCI enabled, PCI buses are not enumerated at boot, as they
are without that config option enabled. No command exists to enumerate the
PCI buses. Hence, unless some board-specific code causes PCI enumeration,
PCI-based Ethernet devices are not detected, and network access is not
available.
This patch implements "pci enum" in the CONFIG_DM_PCI case, thus giving a
mechanism whereby PCI can be enumerated.
do_pci()'s handling of case 'e' is moved into a single location before the
dev variable is assigned, in order to skip calculation of dev. The enum
sub-command doesn't need the dev value, and skipping its calculation
avoids an irrelevant error being printed.
Using a command to initialize PCI like this has a disadvantage relative to
enumerating PCI at boot. In particular, Ethernet devices are not probed
during PCI enumeration, but only when used. This defers setting variables
such as ethact, ethaddr, etc. until the first network-related command is
executed. Hopefully this will not cause further issues. Perhaps in the
long term, we need a "net start/enum" command too?

The DFU test requests U-Boot configure its USB controller in device mode,
then waits for the host machine to enumerate the USB device and create a
device node for it. However, this wait can be fooled if the USB device
node already exists before the test starts, e.g. if some previous software
stack already configured the USB controller into device mode and never
de-configured it. This "previous software stack" could even be another
test/py test, if U-Boot's own USB teardown does not operate correctly. If
this happens, dfu-util may be run before U-Boot is ready to serve DFU
commands, which may cause false test failures.
Enhance the dfu test to fail if the device node exists before it is

test/py contains logic to detect the target crashing and rebooting by
searching the console output for a U-Boot signon message, which will
presumably be emitted when the system boots after the crash/reset.
Currently, this logic only searches for the exact signon message that
was printed by the U-Boot version under test, upon the assumption that
binary is written into flash, and hence will be the version booted after
any reset. However, this is not a valid assumption; some test setups
download the U-Boot-under-test into RAM and boot it from there, and in
such a scenario an arbitrary U-Boot version may be located in flash and
hence run after any reset.
Fix the reset detection logic to match any U-Boot signon message. This

Prior to this change, U-Boot was lazilly (re-)spawned if/when a test
attempted to interact with it, and no active connection existed. This
approach was simple, yet had the disadvantage that U-Boot might be
spawned in the middle of a test function, e.g. after the test had already
performed actions such as creating data files, etc. In that case, this
could cause the log to contain the sequence (1) some test logs, (2)
U-Boot's boot process, (3) the rest of that test's logs. This isn't
optimally readable. This issue will affect the upcoming DFU and enhanced
UMS tests.
This change converts u_boot_console to be a function-scoped fixture, so
that pytest attempts to re-create the object for each test invocation.
This allows the fixture factory function to ensure that U-Boot is spawned
prior to every test. In practice, the same object is returned each time
so there is essentially no additional overhead due to this change.
This allows us to remove:
- The explicit ensure_spawned() call from test_sleep, since the core now
ensures that the spawn happens before the test code is executed.
- The laxy calls to ensure_spawned() in the u_boot_console_*
implementations.
The one downside is that test_env's "state_ttest_env" fixture must be
converted to a function-scoped fixture too, since a module-scoped fixture
cannot use a function-scoped fixture. To avoid overhead, we use the same
trick of returning the same object each time.

The picoseconds to register value divisor(ps_to_regval) should be 60 and not
200. Linux has KSZ9031_PS_TO_REG defined to be 60 as well. 60 is the correct
divisor because the 4-bit skew values are defined from 0x0000(-420ps) to
0xffff(480ps), increments of 60.
For example, a DTS skew value of 420, represents 0ps delay, which should be 0x7.
With the previous divisor of 200, it would result in 0x2, which represents a
-300ps delay.
With this patch, ethernet on the SoCFPGA DE0 Atlas is now able to work with

Micrel PHYs KSZ8021/31 and KSZ8081 have a feature where MDIO address 0
is considered as a broadcast address; the PHY will respond even if it
is not its configured (pinstrapped) address. This feature is enabled
by default.
The Linux kernel disables that feature at initialisation, but not
before it probes the MDIO bus. This causes an issue, because a PHY
at address 3 will be discovered at addresses 0 and 3, but will then
only respond at address 3. Because Linux attaches the first PHY it
discovers on 'eth0', it will attach the PHY from address 0, which
will never answer again.
Fix the issue by disabling the broadcast feature in U-Boot, before
