ec9263b4f1 Fix neighbor discovery ethernet address saving
When a successful neighbor advertisement is received, the ethernet
address should be saved for later use to avoid having to redo the
neighbor discovery process.

For example, with TFTP the address should get saved into
"net_server_ethaddr".  This is being done correctly with ARP for IPv4,
but not for neighbor discovery with IPv6.

eeee0e2b85 net: tftpput: reset timeout_count when an ACK is received
timeout_count is never reset once a tftpput transfer has started. If for
whatever reason timeouts occur frequently, but the server keeps replying
nonetheless, the transfer may be needlessly aborted.

Reset timer_count on reception of an ACK to avoid this situation.

c5cda4ae4a Revert "net: phy: marvell 88e151x: Fix handling of bare RGMII interface type"
This reverts commit 431be621c6.

Section 3.3 of Reduced Gigabit Media Independent Interface (RGMII)
Version 2.0 (4/1/2002) details that a PHYs using a ~2ns internal delay
are referred to as RGMII-ID. This internal delay is optional.

Page 147-148 of the Marvell Doc. No. MV-S107146-U0 Rev. F details
timings of the RX/TX delays. We see that with the TX/RX_CLK delay
enabled, our RX/TX_CTL signal is shifted w.r.t CLK to reflect the delay
added.

In 431be62 there is no timing difference between RGMII and RGMII-ID, and
so programmers wanting to explicitly set their PHY to RGMII will find
that delay added anyway. This could throw off timing if that internal
delay is undesired.

We should be handling all 4 possible RGMII cases of PHY_INTERFACE_MODE:
RGMII, RGMII_ID, RGMII_TXID, and RGMII_RXID. Reverting 431be62
implements this.

See also m88e1111_config_init_rgmii_delays in the equivalent driver in
Linux (drivers/net/phy/marvell.c), which does not set these delays in
RGMII mode.

68e6eca was tested out on an 88E1512 PHY in RGMII-ID mode. This
reversion has been tested by myself on an 88E1518 in RGMII-ID mode. This
patch affects boards using this driver in "rgmii" mode, as the internal
delay will no longer be enabled. Namely kikwood-nsa310s.

395ee74991 net: tftpboot: clear timeout_count on every successful block
We have a some boards that rarely starts networking abnormally, so there are
many timeouts during file transfer. In the same time there is a normal transfer
between timeouts. In this case we can continue transfer (instead of connection
aborting) by just clearing timeout counter on every successful block.

This patch does not affect the case when several timeouts happen one after
another. The transfer will be aborted. Thus the transfer will be
continued in the case of unstable link, but will be aborted in the case
of inaccessible server.

Feature downside: it may greatly slowdown (instead of abort) file transfer
in the case of unstable link.

788b4609db trace: proftool: dump-ftrace should write funcgraph times in ns not us
When converting a U-Boot trace records file to ftrace function graph
format for use by trace-cmd ('proftool -f funcgraph dump-ftrace'), the
time associated to each function is incorrectly saved in microseconds
instead of nanoseconds. Multuply the value by 1000 to fix the issue.

With this change, the trace-cmd output looks consistent. Here is an
example with udelay(25) added to mem_malloc_init() as a test case:

 $ ./tools/proftool -m System.map -t /tmp/trace.bin -f funcgraph \
                    dump-ftrace -o /tmp/trace.dat
 $ trace-cmd report  /tmp/trace.dat >/tmp/trace.log

 u-boot-1     [000]     6.757658: funcgraph_exit:       # 38000.000 us |    }

In the above dump, the udelay() call is reported as taking 26 us which
is consistent with the timestamps (6.719687 - 6.719659 = 0.000026).
Without this patch we would have "0.026 us" instead of "+ 26.000 us".

e7713a7882 dma: ti: k3-udma: Fix BCDMA probe by adding check for MMR_RFLOW
RFLOW config related MMR does not exist incase of BCDMA.
Add check to bypass the RFLOW MMR extraction.
Without this, the probe sequence fails checking for
the MMR_RFLOW region, which is valid only for packet based
DMA and obselete for BCDMA.

08a915719f Gitlab: Remove some "rules:when: always" lines
In commit 399f739be6 ("CI: allow jobs to be run in merge requests") we
added "rules:when: always" to many stages of the pipeline to allow for merge
requests to trigger a run. However based on current Gitlab
documentation, we should still be triggered on merge requests without
this. Furthermore the way we have things written today we always run all
stages of the CI rather than failing out early on problems, which is not
always useful. Remove these as we should still be fine with merge
requests triggering a run.

08c1e15195 Gitlab: Make test.py stage only depend on binman et al testsuite
Our Gitlab pipeline is currently broken up in to several stages. This
was done with the thought process of "we should test tools and if
they're good test emulated targets and if they're good test real
hardware and if they're good test the world". However, in terms of that
first stage it only really matters that binman, et al are still
functional. And for a few years now Gitlab has had a "needs" keyword
that lets you refine pipeline dependencies. Use this to perform the
minor optimization of having test.py only require that tool testing job.
This will become more useful later when we add long running testsuites
that we do not want to block later jobs.

8428e15dc9 sandbox: Adjust configuration to hang on panic()
It is annoying to have sandbox enter a boot loop when an assertion
fails. Hang instead, since then the error message is only printed once
and Ctrl-C can be used to quit, as per normal.

8803745428 gpio: mpc8xxx: Preserve pre-init state of outputs
The mpc8xxx_gpio driver contains a workaround for certain chips
where the previously written state of outputs cannot be read back
from the GPIO data (GPDAT) register (MPC8572/MPC8536). This workaround
consists of tracking the state of GPDAT in a "shadow register" (i.e. a
software variable). The shadow register is initialized to zero.

This results in a problem w.r.t. outputs that are configured to a
high (1) state before U-Boot runs, but not touched by U-Boot itself:
Due to the zero-initialization, these GPIOs end up being set to zero,
the first time that any other output is set.

To avoid such issues initialize the GPDAT shadow register to the value
previously held by any outputs, if possible. On MPC8572/MPC8536 this
should make no difference, i.e. the shadow register should be
initialized to zero on these chips.

This patch has been tested on a MPC8314E-based board.

b3e8c67a91 powerpc: mpc83xx: Allow including initreg.h into multiple files
Globals defined in headers can result in multiple-definition errors
while linking, if they are visible beyond the current translation unit.

This hasn't been a problem for initreg.h so far, but would become a
problem in the next patch, where I use a constant from initreg.h in a
second C file.
