0e116bea52 dm: core: add ofnode_get_path()
Add function for retrieving full node path of a given ofnode.
This uses np->full_name if OF is live, otherwise a call to

e1cbd916c8 log: Convert log values to printf() if not enabled
At present if logging not enabled, log_info() becomes a nop. But we want
log output at the 'info' level to be akin to printf(). Update the macro to
pass the output straight to printf() in this case.

This mimics the behaviour for the log_...() macros like log_debug() and
log_info(), so we can drop the special case for these.

Add new tests to cover this case.

8d9bb98f86 sandbox: log: Avoid build error with !CONFIG_LOG
The pr_cont_test.c test requires CONFIG_LOG since it directly accesses
fields in global_data that require it. Move the test into the CONFIG_LOG
condition to avoid build errors.

Enable CONFIG_LOG on sandbox (not sandbox_spl, etc.) so that we still run
this test. This requires resyncing of the configs.

77bfaad048 test: Fix filesystem tests always being skipped
Commit 1ba21bb06b ("test: Don't unmount not (yet) mounted system")
fixes an issue in the filesystem tests where the test setup may fail
to mount an image and still attempt to unmount it. However, the commit
unintentionally breaks the test setups in two ways.

The newly created unmounted filesystem images are being immediately
deleted due to some cleanup steps being misplaced into finally blocks,
which makes them always run instead of only on failures. The mount calls
always fail since the images never exist, causing the tests to be always
skipped. This patch moves these cleanup calls into the except blocks to
fix this and makes the tests run again.

There are also unmount calls misplaced into finally blocks, making them
run after the tests instead of before the tests. These unmount calls
make the filesystem image file consistent with the changes made to it as
part of the test setup, and this misplacement is making a number of
tests fail unexpectedly.

The unmount calls must be run before the tests use the image, meaning
before the yield call and not in the finally block. They must also be
run as a cleanup step when the filesystem setup fails, so they can't be
placed as the final call in the try blocks since they would be skipped
on such failures. For these reasons, this patch places the unmount calls
both in the except blocks and the else blocks of the final setup step.
This makes the unexpectedly failing tests to succeed again.

Furthermore, this isolates the mount calls to their own try-except
statement to avoid reintroducing the original issue of unmounting a
not-mounted image while fixing the unmount misplacement.

After these fixes, running "make tests" with guestmount available results
in two test failures not related to the mentioned commit. If the
guestmount executables are unavailable, the mounts fallback to using
sudo and result in no failures.

26de4296cc part: Add check for NULL dev_part_str
Some callers (e.g. cmd/fs.c) of fs_set_blk_dev may use a NULL dev_part_str.
While blk_get_device_part_str handles this fine,
part_get_info_by_dev_and_name does not. This fixes commands crashing when
implicitly using bootdevice.

The unit test has also been updated to set bootdevice to a known value and
to restore it after we are done.

6f243e25e6 test/py: improve regular expression for ut subtest symbol matcher
Improve the regular expression that matches unittest symbols in

Currently we do not enforce no prefix in symbol string, but with the
soon to come change in linker lists declaring lists and entries with the
__ADDRESSABLE macro (because of LTO), the symbol file will contain for
every symbol of the form
  _u_boot_list_2_ut_X_2_Y
also symbol
  __UNIQUE_ID___addressable__u_boot_list_2_ut_X_2_YN,
(where N at the end is some number).

In order to avoid matching these additional symbols, ensure that the
character before "_u_boot_list_2_ut" is not a symbol name character.

ff98da0667 sandbox: Add a DSA sandbox driver and unit test
The DSA sandbox driver is used for unit testing the DSA class code.
It implements a simple 2 port switch plus 1 CPU port, and uses a
very simple tag to identify the ports.

The DSA sandbox device is connected via CPU port to a regular Ethernet
sandbox device, called 'dsa-test-eth, managed by the existing eth
sandbox driver.  The 'dsa-test-eth' is not intended for testing the
eth class code however, but it is used to emulate traffic through the
'lan0' and 'lan1' front pannel switch ports.  To achieve this the dsa
sandbox driver registers a tx handler for the 'dsa-test-eth' device.
The switch ports, labeled as 'lan0' and 'lan1', are also registered
as eth devices by the dsa class code this time.  So pinging through
these switch ports is as easy as:

=> setenv ethact lan0
=> ping 1.2.3.5

Unit tests for the dsa class code were also added.  The 'dsa_probe'
test exercises most API functions from dsa.h.  The 'dsa' unit test
simply exercises ARP/ICMP traffic through the two switch ports,
including tag injection and extraction, with the help of the dsa
sandbox driver.

I took care to minimize the impact on the existing eth unit tests,
though some adjustments needed to be made with the addition of
extra eth interfaces used by the dsa unit tests. The additional eth
interfaces also require MAC addresses, these have been added to the
sandbox default environment.

9539f71675 hush: Fix assignments being misinterpreted as commands

assignments would be misinterpreted as commands, instead of being skipped

	=> foo=bar echo baz
	Unknown command 'foo=bar' - try 'help'
