This PR adds support for a popular low-cost 2.4GHz N based AP
Specifications:
- SoC: Qualcomm Atheros QCA9533 (650MHz)
- RAM: 64MB
- Storage: 8 MB SPI NOR
- Wireless: 2.4GHz N based built into SoC 2x2
- Ethernet: 1x 100/10 Mbps, integrated into SoC, 24V POE IN
Installation:
Flash factory image through stock firmware WEB UI
or through TFTP
To get to TFTP recovery just hold reset button while powering on for
around 4-5 seconds and release.
Rename factory image to recovery.bin
Stock TFTP server IP:192.168.0.100
Stock device TFTP adress:192.168.0.254
Notes:
TP-Link does not use bootstrap registers so without this patch reference
clock detects as 40MHz while it is actually 25MHz.
This is due to messed up bootstrap resistor configuration on the PCB.
Provided GPL code just forces 25MHz reference clock.
That causes booting with completely wrong clocks, for example, CPU tries
to boot at 1040MHz while the stock is 650MHz.
So this PR depends on PR #672 to remove 40MHz reference clock.
Thanks to Sven Eckelmann <sven@narfation.org> for properly patching that.

The 666-Add-support-for-MAP-E-FMRs-mesh-mode.patch kernel patches
break the possibility for using an ip4ip6 tunnel interface as a fall
back interface accepting ip4-in-ip6 tunneled packets from any remote
address. This works out of the box with any normal (non-666-patched)
kernel and can be configured by setting up an 'ip -6 tunnel' with type
'any' or 'ip4ip6' and a remote address of '::'.
The misbehavior comes with line 290 the patch which discards all packets
that do not show the expected saddr, even if no single fmr rule was
defined and despite the validity of the saddr was already approved earlier.

This commit adds support for the MT7623A-based UniElec U7623-02 router,
with eMMC storage and 512MB RAM. The router can be delivered with NAND
Flash and more memory, but I only have access to the one configuration.
The DTS is structured in such a way that adding support for
more/different storage/memory should be straight forward.
The device has the following specifications:
* MT7623A (quad-core, 1.3 GHz)
* 512MB RAM (DDR3)
* 8GB storage (eMMC 4.5)
* 2x normal miniPCIe slots
* 1x miniPCIe slot that is connected via an internal USB OTG port
* 5x 1Gbps Ethernet (MT7530 switch)
* 1x UART header
* 1x USB 3.0 port
* 1x SATA 3.0
* 1x 40P*0.5mm FPC for MIPI LCD
* 1x SIM slot
* 12x LEDs (2 GPIO controlled)
* 1x reset button
* 1x DC jack for main power (12V)
The following has been tested and is working:
* Ethernet switch
* miniPCIe slots (tested with Wi-Fi cards)
* USB 3.0 port
* sysupgrade
* reset button
Not working:
* The miniPCIe connected via USB OTG. For the port to work, some MUSB
glue must be added. I am currently in the process of porting the glue
from the vendor SDK.
Not tested:
* SATA 3.0
* MIPI LCD
Installation:
The board ships with u-boot, and the first installation needs to be done
via the bootloader using tftp. Step number one is to update the MBR of
the eMMC, as the one that ships with the device is broken. Since the
device can ship with different storage sizes, I will not provide the
exact steps for creating a valid MBR. However, I have made some
assumptions about the disk layout - there must be one 8MB recovery
partition (FAT32) and a partition for the rootfs (Linux).
The board loads the kernel from block 0xA00 (2560) and I have reserved
32MB for the kernel (65536 blocks). I have aligned the partitions on the
erase block size (4096 byte), so the recovery partition must start on
block 69632 and end on 86016 (16385 sectors). The rootfs is assumed to
start on sector 90112.
In order to install the mbr, you run the following commands from the
u-boot command line:
* tftpboot ${loadaddr} <name of mbr file>
* mmc device 0
* mmc write ${loadaddr} 0x00 1
Run the following commands to install + boot OpenWRT:
* tftpboot ${loadaddr} openwrt-mediatek-mt7623-7623a-unielec-u7623-02-emmc-512m-squashfs-sysupgrade-emmc.bin.gz
* run boot_wr_img
* run boot_rd_img
* bootm
Recovery:
In order to recover the router, you need to follow the installation
steps above (no need to replace MBR).
Notes:
* F2FS is used as the overlay filesystem.
* The device does not ship with any valid MAC address, so a random
address has to be generated. As a work-around, I write the initial
random MAC to a file on the recovery partition. The MAC of the WAN
interface is set to the MAC-address contained in this file on each boot,
and the address of the LAN-interfaces are WAN + 1. The MAC file is kept
across sysupgrade/firstboot.
My approach is slightly different than what the stock image does. The
first fives bytes of the MAC addresses in the stock image are static,
and then the last byte is random. I believe it is better to create fully
random MAC addresses.
* In order to support the miniPCIe-slots, I needed to add missing
pcie-nodes to mt7623.dtsi. The nodes are just c&p from the upstream
dtsi.
* One of the USB3.0 phys (u3phy2) on the board can be used as either USB
or PCI, and one of the wifi-cards is connected to this phy. In order to
support switching the phy from USB to PCI, I needed to patch the
phy-driver. The patch is based on a rejected (at least last time I
checked) PCI-driver submitted to the linux-mediatek mailing list.
* The eMMC is configured to boot from the user area, and according to
the data sheet of the eMMC this value can't be changed.
* I tried to structure the MBR more nicely and use for example a
FAT32-parition for the kernel, so that we don't need to write/read from
some offset. The bootloader does not support reading from
FAT32-paritions. While the command (fatload) is there, it just throws an
error when I try to use it.
* I will submit and hope to get the DTS for the device accepted
upstream. If and when that happens, I will update the patches
accordingly.

This commit adds support for the Mikrotik RouterBOARD RBM33g.
=Hardware=
The RBM33g is a mt7621 based device featuring three gigabit ports, 2
miniPCIe slots with sim card sockets, 1 M.2 slot, 1 USB 3.0 port and a male
onboard RS-232 serial port. Additionally there are a lot of accessible
GPIO ports and additional buses like i2c, mdio, spi and uart.
==Switch==
The three Ethernet ports are all connected to the internal switch of the
mt7621 SoC:
port 0: Ethernet Port next to barrel jack with PoE printed on it
port 1: Innermost Ethernet Port on opposite side of RS-232 port
port 2: Outermost Ethernet Port on opposite side of RS-232 port
port 6: CPU
==Flash==
The device has two spi flash chips. The first flash chips is rather small
(512 kB), connected to CS0 by default and contains only the RouterBOOT
bootloader and some factory information (e.g. mac address).
The second chip has a size of 16 MB, is by default connected to CS1 and
contains the firmware image.
==PCIe==
The board features three PCIe-enabled slots. Two of them are miniPCIe
slots (PCIe0, PCIe1) and one is a M.2 (Key M) slot (PCIe2).
Each of the miniPCIe slots is connected to a dedicated mini SIM socket
on the back of the board.
Power to all three PCIe-enabled slots is controlled via GPIOs on the
mt7621 SoC:
PCIe0: GPIO9
PCIe1: GPIO10
PCIe2: GPIO11
==USB==
The board has one external USB 3.0 port at the rear. Additionally PCIe
port 0 has a permanently enabled USB interface. PCIe slot 1 shares its
USB interface with the rear USB port. Thus only either the rear USB port
or the USB interface of PCIe slot 1 can be active at the same time. The
jumper next to the rear USB port controls which one is active:
open: USB on PCIe 1 is active
closed: USB on rear USB port is active
==Power==
The board can accept both, passive PoE and external power via a 2.1 mm
barrel jack. The input voltage range is 11-32 V.
=Installation=
==Prerequisites==
A USB -> RS-232 Adapter and a null modem cable are required for
installation.
To install an OpenWRT image to the device two components must be built:
1. A openwrt initramfs image
2. A openwrt sysupgrade image
===initramfs & sysupgrade image===
Select target devices "Mikrotik RBM33G" in
openwrt menuconfig and build the images. This will create the images
"openwrt-ramips-mt7621-mikrotik_rbm33g-initramfs-kernel.bin" and
"openwrt-ramips-mt7621-mikrotik_rbm33g-squashfs-sysupgrade.bin" in the output
directory.
==Installing==
**Make sure to back up your RouterOS license in case you do ever want to
go back to RouterOS using "/system license output" and back up the created
license file.**
Serial settings: 115200 8N1
The installation is a two-step process. First the
"openwrt-ramips-mt7621-mikrotik_rbm33g-initramfs-kernel.bin" must be booted
via tftp:
1. Set up a dhcp server that points the bootfile to tftp server serving
the "openwrt-ramips-mt7621-mikrotik_rbm33g-initramfs-kernel.bin"
initramfs image
2. Connect to WAN port (left side, next to sys-LED and power indicator)
3. Connect to serial port of board
4. Power on board and enter RouterBOOT setup menu
5. Set boot device to "boot over ethernet"
6. Set boot protocol to "dhcp protocol" (can be omitted if DHCP server
allows dynamic bootp)
6. Save config
7. Wait for board to boot via Ethernet
On the serial port you should now be presented with the OpenWRT boot log.
The next steps will install OpenWRT persistently.
1. Copy "openwrt-ramips-mt7621-mikrotik_rbm33g-squashfs-sysupgrade.bin" to the device
using scp.
2. Write openwrt to flash using "sysupgrade
openwrt-ramips-mt7621-mikrotik_rbm33g-squashfs-sysupgrade.bin"
Once the flashing completes reboot the router and let it boot from flash.
It should boot straight to OpenWRT.

This commit adds support for the Mikrotik wAP R (RBwAPR-2nD). The change
is based on 3b15eb0 which added support for the wAP 2nD. This change lacks
LED support.
Specifications:
- SoC: Qualcomm QCA9531 (650 MHz)
- RAM: 64 MB
- Storage: 16 MB NOR SPI flash
- Wireless: built-in QCA9531, 802.11b/g/n 2x2:2
- Ethernet: 1x100Mbps
- Power: 9-30V Passive PoE, 9-30V DC jack, 9-30V automotive jack
- SIM card slot
- Mini-PCIe slot
Installation:
1. Login to the Mikrotik WebUI to backup your licence key
2. Change the following settings in System->Routerboard->Settings:
- Boot device: try ethernet once then NAND
- Boot protocol: DHCP
- Force Backup Booter: checked
3. Setup a DHCP/BOOTP server with:
- DHCP-Option 66 (TFTP server name) pointing to a local TFTP
server within the same subnet of the DHCP range
- DHCP-Option 67 (Bootfile-Name) matching the initramfs filename
of the to be booted image, e.g.
openwrt-ar71xx-mikrotik-vmlinux-initramfs.elf
4. Power off the device
5. If this is the second attempt to boot OpenWRT or the boot device isn't
"try ethernet once then NAND," press and hold the reset button while
powered off. If this is the first attempt, this step isn't necessary.
6. Power on the device, holding the reset button for 15-20s if already
pressed from the previous step.
The board should load and start the initramfs image from the TFTP
server. Login as root/without password to the started OpenWRT via SSH
listing on IPv4 address 192.168.1.1. Use sysupgrade to install OpenWRT.
Revert to RouterOS
Use the "rbcfg" package on in OpenWRT:
- rbcfg set boot_protocol bootp
- rbcfg set boot_device ethnand
- rbcfg apply

net: convert sock.sk_wmem_alloc from atomic_t to refcount_t
But an earlier commit left the ticking timebomb:
158f323b9868 ("net: adjust skb->truesize in pskb_expand_head()
Sincerest thanks to Mathias Kresin <dev@kresin.me> for debugging
assistance and to David Woodhouse <dwmw2@infradead.org> for further
guidance, cajoling & patience in interpreting the debug I was giving him
and producing a fix!
Fixes FS#1567

When upstream kernel introduced commit c55fa3cccbc2c672e7f118be8f7484e53a8e9e77
we incorrectly updated our hack integration patch that updates atm/common.c

The correct solution is to drop our ifx_atm_alloc_tx replacement hack
entirely and let the kernel do its thing.
In reality neither pppoatm or BR2684 interfaces actually hit this code,
so the incorrect integration would only be noticed with direct socket
calls which we are unaware of a use-case.
This is not the solution to pppoatm vc-mux failing to work which started
the whole investigation, but let's fix it up anyway.

Support for these devices isn't ready yet and it was only accidentally
pushed in the commit 0da9303e5b ("mac80211: backport "brcmfmac:
cleanup and some rework" from 4.17").

For easier future kernel bumps replace spi patch with upstream version
slightly modified. The modification removes partition definitions which
has been diffrent for some U-Boot versions.
Also this removes unnecessary i2c definition which was in the old patch.

Since the beginning there's been an issue with initializing the Atheros
based MiniPCIe wireless cards. Here's an example of kerenel log:

Following the issue on esppressobin.net forum [1] the workaround seems
to be limiting the speed of PCIe bridge to 1st generation. This fixed
the initialisation of all tested Atheros wireless cards.
The change shouldn't affect the performance for wireless cards,
it could reduce the performance of storage controller cards but since
OpenWrt focuses on wireless connectivity, fixing compatibility with
wireless cards should be a priority.
For the record, the iwlwifi and mt76 cards were not affected by this
issue.
