Enable the VLAN tag offloading mechanism for RGMII single-port devices.
This allows those devices to use 802.1Q VLANs on the ethernet port.
Previously, RX frames were double tagged, as the RX TAG removal flag was
not enabled and an additional 802.1Q header was inserted elsewhere in
the code.
On the TX side, tagging was completely not present for single-port
devices. Enable tagging if an 802.1Q frame should be transmitted and
disable the default tagging mechanism for single-port devices.

all occurencies of wpad-basic and wpad-mini with wpad-basic-wolfssl for

Install via tftp
- NB: need to flash transition image firstly
Firstly install transition image:
(IPQ40xx) # tftpboot 0x84000000 s1300-factory-to-openwrt.img
(IPQ40xx) # sf probe && imgaddr=0x84000000 && source :script
Secondly install openwrt sysupgrade bin:
(IPQ40xx) # run lf
Revert to factory image:
(IPQ40xx) # tftpboot 0x84000000 s1300-openwrt-to-factory.img
(IPQ40xx) # sf probe && imgaddr=0x84000000 && source :script
The kernel and rootfs of factory firmware are on eMMC, and openwrt
firmware is on NOR flash. The transition image includes U-boot
and partition table, which decides where to load kernel and rootfs.
After you firstly install openwrt image, you can switch between
factory and openwrt firmware by flashing transition image.

The Device/Default definition sets a default IMAGE/sysupgrade.bin,
but does not enable it by setting IMAGES. This is not consistent,
and has led to IMAGES being defined at various other places in the
file.
Thus, this patch consolidates the default value for IMAGES by putting
it in Device/Default. Since it's still overwritten where necessary,
this patch is cosmetic.

The DTS files in files-4.19 and files-5.4 are exactly identical
except for one file (qcom-ipq4018-emr3500.dts), which is only
present for 5.4.
Since there is no point in maintaining all these identical files
twice, this patch moves them to the "files" directory.
If there ever was a new kernel with substantial DTS changes, a
new folder would need to be introduced anyway and could easily be
done.

This drops the shebang from all target files for /lib and

This does not touch ar71xx, as this target is just used for
backporting now and applying cosmetic changes would just complicate

The NETGEAR EX61500v2 and EX6150v2 U-Boot does not support booting LZMA
compressed images. Currently, they are using GZIP compressed kernels,

Using a zImage results in a smaller kernel and therefore increases
available space for rootfs and overlayfs.

It was noticed that the the whole MAC can hang when transferring data from
one ar40xx port (WAN ports) to the CPU and from the CPU back to another
ar40xx port (LAN ports). The CPU was doing only NATing in that process.
Usually, the problem first starts with a simple data corruption:
$ wget https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-10.4.0-amd64-netinst.iso -O /dev/null
...
Connecting to saimei.ftp.acc.umu.se (saimei.ftp.acc.umu.se)|2001:6b0:19::138|:443... connected.
...
Read error at byte 48807936/352321536 (Decryption has failed.). Retrying.
But after a short while, the whole MAC will stop to react. No traffic can
be transported anymore from the CPU port from/to the AR40xx PHY/switch and
the MAC has to be resetted.

The USB port on the device is (in contrast to other Aruba boards) real
USB. The AP uses a CP2101 USB TTY converter on the board.
Console baudrate is 9600 8n1.
To enable a full list of commands in the U-Boot "help" command, execute
the literal "diag" command.
Installation
------------
1. Get the OpenWrt initramfs image. Rename it to ipq40xx.ari and put it
into the TFTP server root directory. Configure the TFTP server to
be reachable at 192.168.1.75/24. Connect the machine running the TFTP
server to the ethernet port of the access point.
2. Connect to the serial console. Interrupt autobooting by pressing
Enter when prompted.
3. Configure the bootargs and bootcmd for OpenWrt.
$ setenv bootargs_openwrt "setenv bootargs console=ttyMSM1,9600n8"
$ setenv nandboot_openwrt "run bootargs_openwrt; ubi part aos1;
ubi read 0x85000000 kernel; bootm 0x85000000"
$ setenv ramboot_openwrt "run bootargs_openwrt;
setenv ipaddr 192.168.1.105; setenv serverip 192.168.1.75;
netget; set fdt_high 0x87000000; bootm"
$ setenv bootcmd "run nandboot_openwrt"
$ saveenv
4. Load OpenWrt into RAM:
$ run ramboot_openwrt
5. After OpenWrt booted, transfer the OpenWrt sysupgrade image to the
/tmp folder on the device.
6. Flash OpenWrt:
Make sure you use the mtd partition with the label "ubi" here!
$ ubidetach -p /dev/mtd1
$ ubiformat /dev/mtd1
$ sysupgrade -n /tmp/openwrt-sysupgrade.bin
To go back to the stock firmware, simply reset the bootcmd in the
bootloader to the original value:
$ setenv bootcmd "boot"
$ saveenv

Cell C RTL30VW is a LTE router with tho gigabit ethernets and integrated
QMI mPCIE modem.
This is stripped version of ASKEY RTL0030VW.
Hardware:
Specification:
-CPU: IPQ4019
-RAM: 256MB
-Flash: NAND 128MB + NOR 16MB
-WiFi: Integrated bgn/ac
-LTE: mPCIe card (Modem chipset MDM9230)
-LAN: 2 Gigabit Ports
-USB: 2x USB2.0
-Serial console: RJ-45 115200 8n1
-Unsupported VoIP
Known issues:
None so far.
Instruction install:
There are two methods: Factory web-gui and serial + tftp.
Web-gui:
1. Apply factory image via stock web-gui.
Serial + initramfs:
1. Rename OpenWrt initramfs image to "image"
2. Connect serial console (115200,8n1)
3. Set IP to different than 192.168.1.11, but 24 bit mask, eg. 192.168.1.4.
4. U-Boot commands:
sf probe && sf read 0x80000000 0x180000 0x10000
setenv serverip 192.168.1.4
set fdt_high 0x85000000
tftpboot 0x84000000 image
bootm 0x84000000
5. Install sysupgrade image via "sysupgrade -n"
Back to stock:
All is needed is swap 0x4c byte in mtd8 from 0 to 1 or 1 to 0,
do firstboot and factory reset with OFW:
1. read mtd8:
dd if=/dev/mtd8 of=/tmp/mtd8
2. go to tmp:
cd /tmp/
3. write first part of partition:
dd if=mtd8 of=mtd8.new bs=1 count=76
4. check which layout uses bootloader:
cat /proc/mtd
5a. If first are kernel_1 and rootfs_1 write 0:
echo -n -e '\x00' >> mtd8.new
5b. If first are kernel and rootfs write 1:
echo -n -e '\x01' >> mtd8.new
6. fill with rest of data:
dd if=mtd8 bs=1 skip=77 >> mtd8.new
7. CHECK IF mtd8.new HAVE CHANGED ONLY ONE BYTE! e.g with:
hexdump mtd8.new
8. write new mtd8 to flash:
mtd write mtd8.new /dev/mtd8
9. do firstboot
10.reboot
11. Do back to factory defaults in OFW GUI.

Then fetch it via SCP
Upload nand-factory.ubi to /tmp via SCP, then run
mtd erase rootfs
mtd write /tmp/*nand-factory.ubi rootfs
reboot
To revert to stock image, restore default bootenv in uboot UART console
setenv bootcmd 'bootipq'
printenv
use the saved dump you did back when you installed OpenWrt to verify that
there are no other differences from back in the day.
saveenv
upload the backed up mtd12.bin and run

Where the PC can be resolved to:
>>> l *edma_axi_probe+0x444
0xc067be5c is in edma_axi_probe (./include/linux/string.h:378).
>>> l *edma_axi_probe+0x43f
0xc067be57 is in edma_axi_probe (drivers/net/ethernet/qualcomm/essedma/edma_axi.c:936)
Which leads to the following code fragment:
935 mac_addr = of_get_mac_address(pnp);
936 if (mac_addr)
937 memcpy(edma_netdev[idx_mac]->dev_addr, mac_addr, ETH_ALEN);
Where using mac_addr=0xffffffed (-ENODEV) as source address in memcpy()
is causing the OOPs.

Lets enable RAW NAND and Qcom NANDC drivers again in kernel 5.4.
They were dropped when 5.4 support was introduced due to upstream
changing the symbol names so refreshing was not enough.

This patch backports the upstream patch that adds the 4B_OPCODES flag to w25q256 under 4.19 kernel.
This is needed for ipq40xx and ramips.

This target was switched to kernel 4.19 more than 6 months ago in commit
f342ffd300 ("treewide: kernel: bump some targets to 4.19") and now
with kernel 5.4 support being added it gets harder to support kernel
4.14 in addition to kernel 4.19 and 5.4.

Generate a cpximg that is compatible with the cpximg loader in Compex' u-boot.
The cpximg loader can be started either by holding the reset button during power
up or by entering the u-boot prompt and entering 'cpximg'.
Once it's running, a TFTP-server under 192.168.1.1 will accept an image
appropriate for the board revision that is etched on the board (e.g. 6A04).
The image can be pushed using tftp:
tftp -v -m binary 192.168.1.1 -c put openwrt-ipq40xx-generic-compex_wpj428-squashfs-cpximg-6a04.bin
cpximg files can also be used with the sysupgrade utility in stock images.
(add SSH key in luci for root access)
In mkmylofw_32m, the calculation of the "partition size" has been preferred
to just padding the partition as this will result in less block transfers
during flashing (while the additional complexity is bearable).
