a8c3eca433 net: phy: marvell: Fix problem with phy_reset() clearing BMCR
With commit a058052c [net: phy: do not read configuration register on
reset], phy_reset() will clear the BMCR register. Resulting in bit 12
being cleared (A/N enable). This leads to autonegotiation link problems,
at least on the Marvell Armada ClearFog board. I suspect that other
boards using this driver will be affected as well.

At the of m88e1111s_config(), phy_reset() is called. This is not needed
for the PHY to load the changed configuration, as phy_reset() is called
a few lines before already. So lets call genphy_restart_aneg() here
instead to start the AN correctly.

Tested on clearfog.

651827c0fc tegra: gpio: Show the GPIO value for outputs
The tegra GPIO controller has two ways of reading the value of a GPIO. It
can supply the 'input' value (which is the value read from the pin) and the
'output' value (which is the value being driven from the pin. With a GPIO
set to output mode, the 'input' value is always low which is not very
useful.

This has the unfortunate result that setting a GPIO high still leaves it
showing as low in the 'gpio status' command.

Adjust the driver to check which direction the GPIO is set to, then read
the value from the appropriate register: 'input' for input GPIOs, 'output'
for output GPIOs.

9725543843 test/py: put "Starting U-Boot" into separate log section
The initial boot of U-Boot happens within the context of the first test
that needs to access the U-Boot console when there is no existing
connection. This keeps all activity nestled within test execution, which
fits well into the pytest model. However, this mingles the U-Boot startup
logs with the execution of some test(s), which hides find the boundary
between the two.

To solve this, wrap the "Starting U-Boot" logic into a separate log
section. If the user wishes, they can simply collapse this log section
when viewing the HTML log, to concentrate purely on the test's own
interaction.

93134e18e8 test/py: handle exceptions in console creation
u_boot_console.exec_attach.get_spawn() performs two steps:
1) Spawn a process to communicate with the serial console.
2) Reset the board so that U-Boot starts running from scratch.

Currently, if an exception happens in step (2), no cleanup is performed on
the process created in step (1). That process stays running and may e.g.
hold serial port locks, or simply continue to read data from the serial
port, thus preventing it from reaching any other process that attempts to
read from the same serial port later. While there is error cleanup code in
u_boot_console_base.ensure_spawned(), this is not triggered since the
exception prevents assignment to self.p there, and hence the exception
handler has no object to operate upon in cleanup_spawn().

Solve this by enhancing u_boot_console.exec_attach.get_spawn() to clean
up any objects it has created.

In theory, u_boot_spawn.Spawn's constructor has a similar issue, so fix
this too.

15b51878be Makefile: remove BUILD_TAG from KBUILD_CFLAGS
If BUILD_TAG is part of KBUILD_CFLAGS, then any time the value changes,
all files get rebuilt. In a continuous integration environment, the value
will change every build. This wastes time, assuming that incremental
builds would otherwise occur.

To solve this, remove BUILD_TAG from KBUILD_CFLAGS and add it to CFLAGS
for just the one file that uses it. This does have the disadvantage that
if any other files want to use the flag, we'll need to duplicate this
custom CFLAGS setup logic. However, it seems unlikely we'll need this.

An alternative would be to add BUILD_TAG to the "local version" and remove
the special case code from display_options.c. However, that would affect
the format of the U-Boot signon message, which may negatively affect
people looking for specific data there. The approach of using
file-specific CFLAGS was suggested by Masahiro Yamada.
