This patch is needed to handle interrupts by the second VPE on the Lantiq
ARX100, xRX200, xRX300 and xRX330 SoCs. Switching some ICU interrupts to
the second VPE results in a hang. Currently, the vsmp_init_secondary()
function is responsible for enabling these interrupts. It only enables
Malta-specific interrupts (SW0, SW1, HW4 and HW5).
The MIPS core has 8 interrupts defined. On Lantiq SoCs, hardware
interrupts are wired to an ICU instance. Each VPE has an independent
instance of the ICU. The mapping of the ICU interrupts is shown below:
SW0(IP0) - IPI call,
SW1(IP1) - IPI resched,
HW0(IP2) - ICU 0-31,
HW1(IP3) - ICU 32-63,
HW2(IP4) - ICU 64-95,
HW3(IP5) - ICU 96-127,
HW4(IP6) - ICU 128-159,
HW5(IP7) - timer.
This patch enables all interrupt lines on the second VPE.
This problem affects multithreaded SoCs with a custom interrupt controller.
SOCs with 1004Kc core and newer use the MIPS GIC. At this point, I am aware
that the Realtek RTL839x and RTL930x SoCs may need a similar fix. In the
future, this may be replaced with some generic solution.
Tested on Lantiq xRX200.

This commit replaces patch number 0703 with the upstream accepted
version. This patch requires backporting an additional patch to
avoid conflicts.
The only significant change is the lower maximum MTU. Packets with

xrx200 max MTU is reduced so that it works correctly when set to the
max, and the max MTU of the switch is increased to match.
In 5.10, the switch driver now enables non-standard MTUs on a per-port
basis, with the overall frame size set based on the cpu port. When the
MTU is not used, this should have no effect. The maximum packet size is
limited as large packets cause the switch to lock up.
0702-net-lantiq-add-support-for-jumbo-frames.patch comes from net-next
commit 998ac358019e491217e752bc6dcbb3afb2a6fa3e.
In 5.4, all switch ports are configured to accept the max MTU, as 5.4
does not have port_max_mtu/port_change_mtu callbacks.

In the current state, nvmem cells are only detected on platform device.
To quickly fix the problem, we register the affected problematic driver
with the of_platform but that is more an hack than a real solution.
Backport from net-next the required patch so that nvmem can work also
with non-platform devices and rework our current patch.
Drop the mediatek and dsa workaround and rework the ath10k patches.

Enable the XRX200 PMAC, GSWIP DSA tag and GSIP DSA drivers in the 5.4
kernel config. Update the existing vr9_*.dts{,i} to use the new
Ethernet and switch drivers. Drop the swconfig package from the xrx200
target because swconfig doesn't manage DSA based switches.
The new /etc/config/network format for the DSA driver is not compatible
with the old (swconfig) based one. Show a message during sysupgrade
notifying users about this change and asking them to start with a fresh
config (or forcefully update and then migrate the config manually).
Failsafe mode can now automatically bring up the first lan interface
based on board.json including DSA based setups. Drop
05_set_preinit_iface_lantiq from the xRX200 sub-target as this is not
needed anymore. For now we are keeping it for the ase, xway and
xway_legacy until there's some confirmation that it can be dropped from
there as well.
While here, some boards also receive minor fixups:
- Use LAN1 as LAN1 (according to a photo this port can also be
configured as WAN) on the Buffalo WBMR-300HPD. This makes it easier to
read the port mapping because otherwise we would have LAN{2,3,4} and
WAN (which was the case for the non-DSA version previously).
- vr9_avm_fritz3390.dts: move the "gpio" comment from port 0 and 1 to
their corresponding PHYs
- vr9_tplink_vr200.dtsi: move the "gpio" comment from port 0 to PHY 0
- vr9_tplink_tdw89x0.dtsi: move the "gpio" comment from port 0 to PHY 0

ath79, lantiq, ipq40xx, ramips all use the OpenWrt-specific gpio-export
functionality. Consolidate the patch that adds it under hack-5.10 since
this logic is obviously not target-specific. For those who want to
disable it, unsetting CONFIG_GPIO_SYSFS symbol will disable this code.

The do_carrier arguments was dropped from phy_link_change. The
phylib has always sets the third parameter to true so the flag is
always changed anyway.
of_get_phy_mode() returns an error, or 0 on success, and pass a
pointer, of type phy_interface_t, where the phy mode should be
stored now. So far an error wasn't considered. Print at least an
error message if something unexpected happens.
The stuck queue is now passed to xrx200_tx_timeout (the timeout
handler) but not used so far.
