Pull request net-20250818.
This is mostly code cleanup and fixes, mainly for issues reported by the
Smatch tool, plus two small features for NET_LWIP as well as support for
the BCM54612E phy.
net-common:
- Fix a bunch of issues reported by Smatch
- Introduce CONFIG_DNS
- Add support for BCM54612E phy
net-legacy:
- Add missing SPDX-License-Identifier for files originating from LiMon
net-lwip:
- ping: initialize net_try_count to 1
- sntp: remove redundant sys_check_timeouts()
- tftp: resend initial request
- Add Kconfig option to show ICMP unreachable errors
In cdns_torrent_phy_probe the test for too many lanes configured does
not set an error code before taking the error path. This could lead to a
silent failure if the calling code does not detect the error. Add the
code to return -EINVAL in this case.

In cdns_sierra_pll_bind_of_clocks the variable 'i' is declared but never
assigned to before its value is used in a dev_err. Replace clk_names[i]
by the name passed to device_bind(), i.e., "pll_mux_clk". With that, the
clk_names[] array is unused and can therefore be removed.

The legacy network stack sets net_try_count to 1 at the beginning of the
net_loop() function. This is required for net_start_again() to work
properly. Therefore, set the variable accordingly in the do_ping()
function when NET_LWIP=y. This fixes an issue where a ping to an
unreachable destination would run twice on the same network device. For
example with qemu_arm64_lwip_defconfig:
=> dhcp
DHCP client bound to address 10.0.2.15 (3 ms)
=> ping 10.0.0.1
Using virtio-net#32 device
ping failed; host 10.0.0.1 is not alive
Using virtio-net#32 device
ping failed; host 10.0.0.1 is not alive
=> QEMU: Terminated

The TFTP implementation does not resend the initial request if there is
no response from the server. Since TFTP is based on UDP, there should be
a mechanism to deal with unreliable transmissions at this point, similar
to what we have for data packets. Therefore, introduce request

In mvpp2_probe the code attempts to get a value for "gop-port-id" and

get_timer returns a ulong value representing system time in ms.
On a 64-bit system, this ulong value is 64 bits long. However,
the driver stores it in a 32-bit unsigned integer, which overflows
after 49 days up time, causing the driver to get an incorrect time.
Replace the unsigned int variable with a ulong type to properly store
the value returned by get_timer.

In comphy_cp110_init_serdes_map in comphy_cp110.c there are two fields
in cfg, comphy_lanes_count and comphy_mux_bitcount, which are fetched
from the FDT blob with fdtdec_get_int which returns an int. These two
fields are then tested for being negative. However the fields are
declared as unsigned so those tests must always fail. Change the
declaration of those fields to be int instead of u32 and the code will
work as expected.

Fixes for newer revision of Retronix R-Car V4H Sparrow Hawk and fixes
for boards which enable POSITION_INDEPENDENT and also set non-zero
CONFIG_TEXT_BASE.
The Renesas board defconfigs explicitly set CONFIG_TEXT_BASE=0x50000000,
however U-Boot's POSITION_INDEPENDENT=y build default already places text
at 0x0. These hardcoded overrides are therefore unnecessary and will be
pruned automatically in upcoming resyncs.
Remove the CONFIG_TEXT_BASE lines from the following defconfigs:

The Retronix R-Car V4H Sparrow Hawk old revision EVTA1 does not have MicroSD
voltage switch populated on the board, therefore the board supports only 3V3
and non-UHS MicroSD cards. While the EVTB1 board is populated with Winbond
W77Q51NW SPI NOR, the EVTA1 board is populated with Spansion S25FS512S SPI
NOR, those those SPI NOR IDs to discern the two board revisions and apply
the MicroSD related DT changes.
The MicroSD related DT changes modify the regulator node, which is now a
regulator-fixed and supplies only 3V3, and remove sd-uhs-sdr50 and
sd-uhs-sdr104 properties from the MicroSD slot controller node.
The MicroSD related DT changes cannot be applied as DTO, because the base
DT contains nodes which have to be removed in case of EVTA1, but have to
be present in case of EVTB1 and newer revisions of the board. Because the
EVTA1 is an old revision of the board that is not generally available, it
is better to special case it and keep the base DT compatible with EVTB1
and newer revisions of the board which are actually available.
