malloc: work around some memalign fragmentation issues
Use of memalign can trigger fragmentation issues such as:
// Internally, this needs to find a free block quite bit larger than s.
// Once the free region is found, any unaligned "padding" immediately
// before and after the block is marked free, so that the allocation
// takes only s bytes (plus malloc header overhead).
p = memalign(a, s);
// If there's little fragmentation so far, this allocation is likely
// located immediately after p.
p2 = malloc(x);
free(p);
// In theory, this should return the same value for p. However, the hole
// left by the free() call is only s in size (plus malloc header overhead)
// whereas memalign searches for a larger block in order to guarantee it
// can adjust the returned pointer to the alignment requirements. Hence,
// the pointer returned, if any, won't be p. If there's little or no space
// left after p2, this allocation will fail.
p = memalign(a, s);
In practice, this issue occurs when running the "dfu" command repeatedly
on NVIDIA Tegra boards, since DFU allocates a large 32M data buffer, and
then initializes the USB controller. If this is the first time USB has
been used in the U-Boot session, this causes a probe of the USB driver,
which causes various allocations, including a strdup() of a GPIO name
when requesting the VBUS GPIO. When DFU is torn down, the USB driver
is left probed, and hence its memory is left allocated. If "dfu" is
executed again, allocation of the 32M data buffer fails as described
above.
In practice, there is a memory hole exactly large enough to hold the 32M
data buffer than DFU needs. However, memalign() can't know that in a
general way. Given that, it's particularly annoying that the allocation
fails!
The issue is that memalign() tries to allocate something larger to
guarantee the ability to align the returned pointer. This patch modifies
memalign() so that if the "general case" over-sized allocation fails,
another allocation is attempted, of the exact size the user desired. If
that allocation just happens to be aligned in the way the user wants,
(and in the case described above, it will be, since the free memory
region is located where a previous identical allocation was located),
the pointer can be returned.
This patch is somewhat related to 806bd245b1ab "dfu: don't keep
freeing/reallocating". That patch worked around the issue by removing
repeated free/memalign within a single execution of "dfu". However,
the same technique can't be applied across multiple invocations, since
there's no reason to keep the DFU buffer allocated while DFU isn't
running. This patch addresses the root-cause a bit more directly.
This problem highlights some of the disadvantages of dynamic allocation
and deferred probing of devices.
This patch isn't checkpatch-clean, since it conforms to the existing
coding style in dlmalloc.c, which is different to the rest of U-Boot.

Implement "pci enum" command for CONFIG_DM_PCI
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

ARM: tegra: shut down USB device controller at boot
When loading U-Boot into RAM over USB protocols using tools such as
tegrarcm or L4T's exec-uboot.sh/tegraflash.py, Tegra's USB device
mode controller is initialized and enumerated by the host PC running
the tool. Unfortunately, these tools do not shut down the USB
controller before executing the downloaded code, and so the host PC
does not "de-enumerate" the USB device. This patch implements optional
code to shut down the USB controller when U-Boot boots to avoid leaving
a stale USB device present.

test/py: make crash detection more robust
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
prevents false negatives.

test/py: add DFU test
Add a test of DFU functionality to the Python test suite. The test
starts DFU in U-Boot, waits for USB device enumeration on the host,
executes dfu-util multiple times to test various transfer sizes, many
of which trigger USB driver edge cases, and finally aborts the DFU
command in U-Boot.
This test mirrors the functionality previously available via the shell
scripts in test/dfu, and hence those are removed too.

This enhancement is backwards-compatible; old boardenv contents that don't

test/py: drain console log at the end of any failed test
Tests may fail for a number of reasons, and in particular for reasons
other than a timeout waiting for U-Boot to print expected data. If the
last operation that a failed test performs is not waiting for U-Boot to
print something, then any trailing output from U-Boot during that test's
operation will not be logged as part of that test, but rather either
along with the next test, or even thrown away, potentiall hiding clues
re: the test failure reason.

test/py: move U-Boot respawn trigger to the test core
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.

net: phy: micrel: fix divisor value for KSZ9031 phy skew
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
1Gb ethernet.
Use the 'autoneg' flag available in phydev when checking if
autoneg is in use.
The previous implementation was checking directly in the PHY
if autoneg was supported. Some PHYs will report that autoneg
is supported, even when it is disabled. Thus it is not possible
to use that bit to determine if autoneg is currently in use or
not.

When configuring a PHY in fixed (forced) link mode, in order for
the changes to be applied, either one of these conditions must
be triggered:
1- PHY is reset
2- Autoneg is restarted
3- PHY transitions from power-down to power-up

configuration is not applied in the PHY.

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
Linux is started.
