The name of squashfs is confusing since in reality it's a really old
version using an old lzma library. This tools is used for old ath79
netgear target and to produde a fake squasfs3 image needed for some
specific bootloader from some OEM (AVM for example)
Rename squashfs tool to squasfs3-lzma to better describe it.
Rename the installed bin from mksquashfs-lzma to mksquashfs3-lzma.
Use tar transform to migrate the root directory in tar to the new
naming.
Drop redundant PKG_CAT variable not needed anymore.
Also update any user of this tool.

FCC ID: A8J-EPG600
Engenius EPG600 is an indoor wireless router with
1 Gb ethernet switch, dual-band wireless,
internal antenna plates, USB, and phone lines (not supported)
this board is a Senao device:
the hardware is equivalent to EnGenius ESR600 (except for phone lines)
the software is Senao SDK which is based on openwrt and uboot
which uses the legacy Senao header with Vendor / Product IDs
to verify the firmware upgrade image.
**Specification:**
- MT7620 SOC MIPS 24kec, 2.4 GHz WMAC, 2x2
- RT5592N WLAN PCI chip, 5 GHz, 2x2
- QCA8337N Gb SW RGMII GbE, SW P0 -- SOC P5, 5 LEDs
- 40 MHz clock
- 16 MB FLASH MX25L12845EMI-10G
- 64 MB RAM NT5TU32M16
- UART console J2, populated
- USB 2.0 port direct to SOC
- 6 GPIO LEDs power, 2G, 5G, wps2g, wps5g, line
- 3 buttons reset, wps, "reg" (registeration)
- 4 antennas internal omni-directional plates
NOT YET SUPPORTED: VoIP
- Si3050-FT + Si3019-FT Voice DAA, SPI control, PCM data
- Phone Ports "TEL", "LINE" RJ11, 4P2C (2 pins)
**MAC addresses:**
MAC address labeled as MAC ADDRESS
MACs present in both wifi cal data and uboot environment
eth0.1/phy1 ---- *:82 rf 0x4
phy0 ---- *:83 factory 0x4
eth0.2 MAC *:b8 "wanaddr"
**Installation:**
Method 1: Firmware upgrade page:
(if you cannot access the APs webpage)
factory reset with the reset button
connect ethernet to a computer
OEM webpage at 192.168.0.1
username and password 'admin'
Navigate to gear icon, "Device Management", "Tools"
select the factory.dlf image
Upload and verify checksum
Method 2: Serial to upload initramfs:
Follow directions for TFTP recovery
upload and boot initramfs and do a sysupgrade
**TFTP recovery:**
Requires UART serial console, reset button does nothing
rename initramfs-kernel.bin to 'uImageEPG600'
make available on TFTP server at 192.168.99.8
power board, interrupt boot with "4"
execute `tftpboot` and `bootm` (with the load address)
**Return to OEM:**
Images from OEM are provided, but not compatible
with openwrt sysupgrade. So it must be modified.
Alternatively, back up all mtd partitions before flashing
**Note on switch registers:**
The necessary registers needed for the QCA8337 switch
can be read from interrupted boot (tftpboot, bootm)
by using the following lines in the switch driver ar8327.c
in the function 'ar8327_hw_config_of'
where 'qca,ar8327-initvals' is parsed from DTS
before the new register values are written:
pr_info("0x04 %08x\n", ar8xxx_read(priv, AR8327_REG_PAD0_MODE));
pr_info("0x08 %08x\n", ar8xxx_read(priv, AR8327_REG_PAD5_MODE));
pr_info("0x0c %08x\n", ar8xxx_read(priv, AR8327_REG_PAD6_MODE));
pr_info("0x10 %08x\n", ar8xxx_read(priv, AR8327_REG_POWER_ON_STRAP));

in order for the option ephy-disable to work
without also needing ephy-base option,
we have to skip all the lines that write to mdio addresses that
assume those addresses do not have an external switch.
Otherwise, ephy ports will be disabled in hardware,
but register writes still happen as if they are enabled.
Split the functions so that other things are done first,
and ephy port setup can be skipped with a simple "return".
Tested on Engenius EPG600 (MT7620A ver:2 eco:3)

Installation:

* U-Boot allows booting an initramfs image via TFTP as follows:
setenv ipaddr 192.168.1.1

Known Limitations:
* The 2.5G WAN port labeled 'wan' only works for speeds up to 1G at the
moment. If connected to a multi-gig port the speed has to be manually
set to 1G/full either for the switch port or in OpenWrt. For example
add the following to /etc/rc.local to set it on boot:
/usr/sbin/ethtool -s wan speed 1000 duplex full
Revert to stock firmware:
* Flash the stock firmware to the bootloader using TFTP/NMRP.

f584fb2f7e kernel: import accepted MediaTek Ethernet patches
Unrefreshed patches caused the CI to fail.
Signed-off-by: Paul Spooren <mail@aparcar.org>
With 5.15 kernel version Linksys EAX500 family devices suffered from a
big regression where the Ethernet switch became silent and started to
malfunction.
It was discovered later that the cause was not really the kernel upgrade
itself but a hackish implementation of the hw implementation of these
special routers.
In the original Linksys source code, GPIO 63 was handled in a special way
and was reset on reboot.
Normally GPIO 63 is used for pcie2 reset but in every device we support,
pcie2 is actually never used as nothing is attached to it.
Linksys rerouted GPIO 63 to the switch reset pin and deviates from
common hw implementation.
Till now it was used an hack to handle this case... It was set pcie3 as
working (while actually nothing was connected), set it to output low
(for assert-deassert from the pcie init code) and be done with it.
The result was that the GPIO was reset for enough time in early boot and
everything worked correctly.
This hack implementation was born to fail from the very start and in
kernel 5.15 finally problem arised.
In 5.15 pcie code changed and now the GPIO reset pin is not asserted as
probe won't fail if nothing is connected to the line (the old behaviour)
This result in the switch hold the reset pin and the Ethernet switch
dead.
On top of that with 5.15 code got optimized and simply attaching the
GPIO reset to the mdio wasn't enough as the switch require at least 10ms
to be correctly reset.
So implement finally a correct solution where:
- pcie2 is correctly disabled (nothing attached, unused)
- drop the wrong output-low for pcie2 reset pin
- define GPIO 63 as switch reset
- Add the reset-gpios to the mdio0 node
- Set the reset-post-delay-us to 12ms to correctly give time the switch
to reset

before 'qca,ar8327-initvals' is parsed from DTS and written.
for example:
pr_info("0x04 %08x\n", ar8xxx_read(priv, AR8327_REG_PAD0_MODE));

Split the DTS to be used with similar boards made by Senao,
dual-band routers with Atheros / Qualcomm ethernet switch.
Set initvals for the switch in each device's DTS.
Set some common calibration nvmem-cells in DTSI.
While at it, fix MTD partition node names.

By specifying the flag "denx,fit" for partition "kernel", the kernel
try to find rootfs in the same partition during boot. Reality is that
the placement of rootfs is precisely determined by the name of another
partition -"ubi".
It was also found that on some device (for example devices with NAND
chips), the "Denx search engine" manages to find roots at the end of
partition "kernel", but such partition doesn't exist and is empty
there.
Fix this by removing the "denx,fit" flag from partition "kernel". With
this change the original behavior of searchif rootfs in partition "ubi"
is restored.
