e63326e26a lantiq/xrx200: move 8M flash devices to a small flash subtarget
Images for xrx200 8M flash are either not building due to image
size (TD-W8970, TD-W8980) or building such that the available
free space in the overlayfs is too little to be useful.

To keep images for these devices buildable, move them into a
small flash variant of the xrx200 subtarget.  As these devices
are NOR flash only, remove NAND and UBI references from the
kernel config to gain some additional image size reduction.

The apparent 8M flash devices Arcadyan VGV7510KW22-brn,
Arcadyan VGV7519-brn and Lantiq Easy80920-nor seem to exist in
order to create special "factory" installation images for these
devices (which actually have larger flash: 16MB for the
Arcardyan devices; 64MB for the Lantiq device).  As a
considerable amount of surgery would appear to be required to
the uboot-lantiq package structure to separate the "factory"
from the "sysupgrade" device recipes for these devices they
remain in the xrx200 target - if factory images aren't now
created, 23.05.x factory images should suffice for initial
installation.

Tested on: Netgear DM200, TP-Link TD-W8980,
           AVM Fritz7490 (xrx200 subtarget: image build only)

c143fd9091 lantiq: ltq-atm: use platform_get_irq to get irqs
This is required for linux-6.1 compatibility.

IRQs are not automatically mapped from HW to virtual IRQ numbers when
the IRQ domain is registered. This happens when the IRQ number is read
from the device tree based on the IRQ domain from the device tree now.
In kernel 5.15 it was done when the IRQ domain was registered.

2f484aeff5 ltq-atm/ltq-ptm: avoid unnecessary build dependencies
Right now, both ltq-adsl-mei and ltq-vdsl-mei are always built, even
when they aren't necessary for the selected variant. This can cause the
build to fail, for example ltq-vdsl-mei doesn't build successfully here
on xway target due to the vectoring callback.

Make these dependencies conditional on the specific package variants,
so they are only built when actually needed.

d2d32dcd5f kernel: lantiq: fix Module.symvers handling
If an external module uses exported symbols from another external
module, Kbuild needs to have full knowledge of all symbols to
avoid spitting out warnings about undefined symbols.

Use PKG_EXTMOD_SUBDIRS to point to the build directory which contains
the Module.symvers.

Pass KERNEL_MAKE_FLAGS to the external module build, to inject
KBUILD_EXTRA_SYMBOLS. KBUILD_EXTRA_SYMBOLS holds a space separated list
of Module.symvers, which list all exported symbols.

ff3cfe0848 ltq-atm/ltq-ptm: re-enable/fix reset_ppe() functionality for VR9
This patch re-enables the reset_ppe() functionality for VR9 targets by using
the new lantiq rcu subsystem. The reset sequence in the reset_ppe() function
was taken from the ppa datapath driver of lantiq UGW 7.4.1.

Additionally it adds the required reset definitions to the vr9 dtsi file.

It also prepares the reset_ppe() function calls for the other lantiq targets.

This feature is needed to be able to switch between ltq-atm/ltq-ptm driver
in ATM/PTM Auto-Mode at runtime.

17eb826a70 ltq-atm: rewrite tx path to use IRQs
The ATM subsystem is different from the generic ethernet NICs. The ATM
subsystem requires a callback when a packet has been sent. It means a
tx skb_buff need to be used after it has sent. While the generic NIC
can fill up the TX ring and free skb_buffs if it encounter a ring buffer slot
with an already sent skbuff.
The ATM drivers need call the pop() function after it has send a
single ATM package. The ATM subsystem controls via this ways the queuing.

The ppe engine use DMA channels for read and write. Every atm_vcc has it's
own TX DMA channel and each TX DMA channel has it's own ring buffer.

The old driver had multiple issues:
- Call the subsystem callback at the beginning of tx function (ppe_send).
  Didn't allowed the ATM subsystem to control the enqueued package
  amount.
- Filled up the TX ring until full and fail futher
- copy or decouple the skb from all other subsystem before giving it
  over to TX ring

The new tx path uses interupts.
- call the subsystem callback _after_ it was sent by hardware
- no need to copy our decouple the skb any more
- gives back control to the atm subsystem over the enqueued packages
- use an interupt for every sent atm package

Using interupts shouldn't be a problem because of the slow uplink bandwidth of
ADSL.
The speed _through_ the DSL router was always as high as it should
be, only traffic generated on the router itself were affected.

After changing to new tx path, the speed of iperf's run on the
router itself reached the same speed. The master/trunk wasn't as much
affected because of TCP optimisations (reboot-5022-gb2ea46fe236a).
The following results are taken on the remote server, which receives
the stream over the internet and the DSL line.

The sync moves between every sync a litte bit, but is so far stable

ee0091ebed lantiq: ltq-atm: set carrier status
This prevents the unconditionally start of pppd since netifd will be
triggered if the device goes into showtime. The same applies to lost
showtime as well.

In compare to the ptm driver, this changeset isn't strictly required,
since the "not in showtime" message is limited to the debug loglevel.
But it reduces the amount of ppp related messages significant.
