net: ipv6: Add support for default gateway discovery.
In IPv6, the default gateway and prefix length are determined by receiving

https://www.rfc-editor.org/rfc/rfc4861.
Add support for sending router solicitation (RS) and processing router
advertisements (RA).
If the RA has prefix info option and following conditions are met, then
gatewayip6 and net_prefix_length of ip6addr env variables are initialized.
These are later consumed by IPv6 code for non-local destination IP.

net: phy: Make phy_interface_is_rgmii a switch statement
Recent commit 75d28899e3e9 ("net: phy: Synchronize PHY interface modes
with Linux") reordered the enum definitions. This exposed a problem
in range checking functions to identify the interface type. Though
this specific api wasn't impacted (all the RGMII definitions remained
within range), this experience should be used to never to have to face
this kind of challenge again.
While it is possible for the phy drivers to use the enums directly,
drivers such as dp83867, dp83869, marvell, micrel_ksz90x1 etc use this
api.

drivers: net: fsl-mc: fix MAC address fixup procedure
In the process of adopting CONFIG_DM_ETH on the DPAA2 based platforms,
interfaces which were previously defined as "xgmii" were transitioned to
be defined as "xfi" in the DTS.
See the commit below for reference:
commit 87274918f2f4 ("arm: dts: ls2088ardb: add DPMAC and PHY nodes")
Then Vladimir's commit replaced all occurrences of "xfi" with
"10gbase-r" in an effort to make U-Boot work with the same device tree
as Linux.
commit 77b11f760416 ("net: replace the "xfi" phy-mode with "10gbase-r"")
These changes to the phy_interface_t of an Ethernet port meant that the
mc_fixup_mac_addrs() function was no longer capable to properly fixup
the MAC addresses. The problem arises from the fact that the hardcoded
information about an interface (wriop_get_enet_if()) was no longer
matching any actual device.
For example, the function tried to search for "DPMAC1@xgmii1" by name
using eth_get_dev_by_name() when only "DPMAC1@10gbase-r" was available.
This function removes the need to rely on the hardcoded information by
iterating through all the UCLASS_ETH devices which are DPAA2 and request
a fixup for each of them.

Errata ID i2331 CPSW: Device lockup when reading CPSW registers
Details: A device lockup can occur during the second read of any CPSW
subsystem register after any MAIN domain power on reset (POR). A MAIN
domain POR occurs using the hardware MCU_PORz signal, or via software
using CTRLMMR_RST_CTRL.SW_MAIN_POR or CTRLMMR_MCU_RST_CTRL.SW_MAIN_POR.
After these resets, the processor and internal bus structures may get
into a state which is only recoverable with full device reset using
MCU_PORz.
Due to this errata, Ethernet boot should not be used on this device.
Workaround(s): To avoid the lockup, a warm reset should be issued after
a MAIN domain POR and before any access to the CPSW registers. The warm
reset realigns internal clocks and prevents the lockup from happening.
Workaround above errata by calling do_reset() in case of cold boot in
order to trigger warm reset. This needs enabling SYSRESET driver in R5
SPL to enable TI SCI reset driver.

pinctrl: mediatek: set R1/R0 in case pullen/pullsel succeeded
Commit dafe0fbfb0f3 ("pinctrl: mediatek: rewrite mtk_pinconf_set and
related functions") changed the logic deciding to set R0 and R1
registers for V1 devices.
Before:
/* Also set PUPD/R0/R1 if the pin has them */
err = mtk_hw_set_value(dev, pin, PINCTRL_PIN_REG_PUPD, !pullup);
if (err != -EINVAL) {
mtk_hw_set_value(dev, pin, PINCTRL_PIN_REG_R0, r0);
mtk_hw_set_value(dev, pin, PINCTRL_PIN_REG_R1, r1);
}
Tracing mtk_pinconf_bias_set_pullen_pullsel shows that the function
always either returns 0 in case of success or -EINVAL in case any error
has occurred. Hence the logic responsible of the decision to program R0
and R1 has been inverted.
This leads to problems on BananaPi R2 (MT7623N) when booting from
SDMMC, it turns out accessing eMMC no longer works since
U-Boot 2022.07:
MT7623> mmc dev 0
Card did not respond to voltage select! : -110
The problem wasn't detected for a long time as both eMMC and SDMMC work
fine if they are used to boot from, and hence R0 and R1 were already
setup by the bootrom and/or preloader.
Fix the logic to restore the originally intended and correct behavior
and also change the descriptive comment accordingly.

Enable Quality of Service (QoS) blocks for Display SubSystem (DSS), by
servicing the DSS - DDR traffic from the Real-Time (RT) queue. This is
done by setting the DSS DMA orderID to 8.
The C7x and VPAC have been overwhelming the DSS's access to the DDR
(when it was accessing via the Non Real-Time (NRT) Queue), primarily
because their functional frequencies, and hence DDR accesses, were
significantly higher than that of DSS. This led the display to flicker
when certain edgeAI models were being run.
With the DSS traffic serviced from the RT queue, the flickering issue
has been found to be mitigated.
The am62a qos files are auto generated from the k3 resource partitioning
tool.
Section-3.1.12, "QoS Programming Guide", in the AM62A TRM[1], provides
more information about the QoS, and section-14.1, "System Interconnect
Registers", provides the register descriptions.
arm: mach-k3: j7200: Fix firewall warnings at boot time
J721E and J7200 have same file j721e_init.c which had the firewall
configs for J721E being applied on J7200 causing the warnings. Split the
firewalls for both the boards to remove those warnings.
board: Fix documentation for Snapdragon based Samsung and Qualcomm boards
The current documentation for Snapdragon based Samsung
and Qualcomm boards is vague in the sense that at one place
it mentions that u-boot can be used as a replacement for ABL
bootloader and at another it mentions that u-boot is loaded
as an Android boot image through ABL.
K3 devices have some firewalls set up by ROM that we usually remove so
that the development is easy in HS devices.
While removing the firewalls disabling a background region before
disabling the foreground regions keeps the firewall in a state where all
the transactions will be blacklisted until all the regions are disabled.
This causes a race for some other entity trying to access that memory
region before all the firewalls are disabled and causes an exception.
Since the background regions configured by ROM are in such a manner
that they allow all transactions, don't touch the background regions at
all.
