ath25 has been on life support for the last couple of releases, eventually
leading to marking it as source-only in 2023.
It has been basically only touched to do a kernel bump so that we can make
the new OpenWrt release which was a challenge due to small RAM amount.
However, with the attempt of kernel 6.1 update it turns out that kernel
cannot even finish booting due to RAM constraints, so its time to let this

When both variants of ath10k drivers are selected, any driver that is
selected along is being built twice, one for each ath10k variant.
Avoid these redundant builds by introducing an optional second parameter
to config_package that lists the variants for which the package is to be
built.
If the symbol is to be set for all of the variants, $(ALL_VARIANTS) can
be used. This is the case for the mac80211 and cfg80211 modules. If
the parameter is empty, then the module will be selected and thus built
when the first variant is compiled.

Having different build directories is the default when the package
Makefile defines more than one variant.
Mac80211 overrides PKG_BUILD_DIR, not taking different variants in
consideration, which causes clobbering the directories when both
variants are built.
When compiled with AUTOREMOVE=y, the effect is that the package is
unnecessarily rebuilt when the package is compiled again.
Wihout AUTOREMOVE, the problem is worse: the second variant will not be
rebuilt, and you end up with the smallbuffers variant being a copy of
the regular one.

This adds support for the Fritzbox 7490 device. It contains two
SoCs, one Lantiq without WiFi and one QCA9558 with 2.4GHz
and 5 GHz WiFi. Only the Lantiq has access to the flash memory,
the Atheros runs fully from RAM and is booted by using a remoteproc
kernel module and is not supported with this commit.
The devices were manufactured with varying NAND chips which
requires Micron and non-Micron versions of the images.
Specifications:
- SoC: Lantiq 500 MHz
- RAM: 256 MB
- Storage: 512 MB NAND, 1MB FLASH
- Wireless, separate SOC QCA9558 with 128MB RAM (not supported yet):
· Qualcomm-QCA9558 w/ 3×3 MIMO for 2.4GHz 802.11b/g/n
· Qualcomm-QCA9880 w/ 3×3 MIMO for 5GHz 802.11a/ac
· AG71xx ethernet
- Ethernet: Built-in AR 803x, 7 port 4 phy switch,
4x 1000/100/10 port, Port 5 is fixed and connected to the WASP SOC
- Renesas µPD720202 USB3 PCIe, requires firmware binary on the device
- VDSL2 modem
Unsupported:
- DECT and ISDN telephony
Installation:
Check which NAND the device has by using the following procedure with
stock firmware:
Go to to http://<fritzbox_ip>/support.lua, download the support data
file and search for string "NAND device" to get the manufacturer kernel
output.
Use Micron image if Micron is displayed otherwise the non-Micron image.
Use the eva_ramboot.py script to boot the initramfs image. Follow the
procedure to interrupt booting by ftp into 192.168.178.1 within
5 seconds after poweron.
Then transfer the sysupgrade image to the device and run sysupgrade to
flash it to the NAND.
For making USB work, an renesas xhci firmware file (e.g. v2026) is
needed and it should be copied to /lib/firmware/ (file name
renesas_usb_fw.mem).

started fixing wrong switch_lan_bmp that defined lan there weren't
actually present. This displayed a fragility in the malibu phy init code
in qca-ssdk.
Add patch to fix this. Also update each DTS with the new required
property if needed.
The new binding malibu_phy_start_addr is required with devices that
place the malibu first PHY referring port1 on a different PHY addres
than 0. The most common configuration is 0 but some device (for example
Qnap 301W) place the malibu PHY at an offset to address 16.
Refer to ipq8074-ess dtsi for extensive description on how to derive
this value.
Quoting the patch detailed description:
The usage of first_phy_addr is EXTREMELY FRAGILE and results
in dangerous results if the OEM (or anyone that by chance try to
implement things in a logical manner) deviates from the default values
from the "magical template".
To be in more details. With QSDK 12.4, some tweaks were done to improve
autoneg and now on every call of port status, the phydev is tried to
add. This resulted in the call and log spam of an error with ports that
are actually not present on the system with qsdk reporting phydev is
NULL. This itself is not an error and printing the error is correct.
What is actually an error from ages is setting generic bitmap reporting
presence of port that are actually not present. This is very common on
OEM where the switch_lan_bmp is always a variant of 0x1e (that on bitmap
results in PORT1 PORT2 PORT3 PORT4 present) or 0x3e (PORT1 PORT2 PORT3
PORT4 PORT5). Reality is that many device are used as AP with one LAN
port or one WAN port. (or even exotic configuration with PORT1 not
present and PORT2 PORT3 PORT4 present (Xiaomi 3600)
With this finding one can say... ok nice, then lets update the DT and
set the correct bitmap...
Again world is a bad place and reality is that this cause wonderful
regression in some case of by extreme luck the first ever connected
port working and the rest of the switch dead.
The problem has been bisected to all the device that doesn't have the
PORT1 declared in any of the bitmap.
With this prefaction in mind, on to the REAL problem.
malibu_phy_hw_init FOR SOME REASON, set a global variable first_phy_addr
to the first detected PHY addr that coincidentally is always PORT1.
PORT1 addr is 0x0. The entire code in malibu_phy use this variable to
derive the phy addrs in some function.
Declaring a bitmap where the PORT1 is missing (or worse PORT4 the only
one connected) result in first_phy_addr set to 1 or whatever phy addr is
detected first setting wrong value all over the init stage.
To fix this, introduce a new binding malibu_first_phy_addr to manually
declare the first phy that the malibu PHY driver should use and permit
to detach it from port bmp detection. The legacy detection is kept for
compatibility reason.

Some local patches have been sent to upstream and they are slightly
different from the upstream version. So it's better to replace them
to avoid conflicts with the new mac80211 backport driver. The
different parts have been merged into patch 996.
This commit also includes some additional fixes:
* Fix watchdog function.
* Improve MT7620 register initialization.
* Introduce DMA busy watchdog for rt2800.
P.S.
Sometimes rt2800 series chips may fall into a DMA busy state. The
tx queues become very slow and the client cannot connect to the AP.
Usually, We can see a lot of hostapd warnings at this point:
'hostapd: IEEE 802.11: did not acknowledge authentication response'
The DMA busy watchdog can help the driver automatically recover
from this abnormal state. By the way, setting higer 'cell_density'
and disabling 'disassoc_low_ack' can significantly reduce the
probability of the DMA busy.
