* ath79: use board name in LED migrationsAdrian Schmutzler2019-10-211-4/+3
| | | | | | | | | | | | | Several devices added to LED migration script will just have their (old) board name converted to tp-link. By using a variable for this, the amount of code in the migration script can be reduced and the chance for typos is reduced. This patch also introduces the marker for beginning of a pattern "^" to the regex, so the match is more specific. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* ath79: fix patching ath9k MAC address for MyNet WiFi Range ExtenderAdrian Schmutzler2019-10-211-1/+1
| | | | | | | | | | | | | | | | | The code line patching ath9k MAC address for this device contains a wrong number of arguments including an unset "$mac", which looks like a typo or copy/paste mistake. This has been introduced already in the device support commit 745dee11ac78 ("ath79: add support for WD My Net Wi-Fi Range Extender"). This patch just removes the "$mac" argument, leaving a formally valid line. (No on-device test has been performed.)

* treewide: use a single ath10k MAC patching function with checksumAdrian Schmutzler2019-10-151-22/+22
| | | | | | | | | | | | | | | | While all ath10k eeproms have a checksum field, so far two functions for patching ath10k MAC address have been present (and been used). This merges code to provide a single function ath10k_patch_mac in caldata.sh, having its name in accordance with ath9k functions. By doing so, correct MAC patching for current and future ath10k devices should be ensured. This patch adds checksum adjustments for several targets on ath79 and lantiq.

Specifications: - QCA9531 SoC - 650/400/216 MHz (CPU/DDR/AHB) - 1x 10/100 Mbps WAN Ethernet, 48V PoE-in - 1x 10/100 Mbps LAN Ethernet, pass-through 48V PoE-out - 1x manual pass-through PoE switch - 64 MB RAM (DDR2) - 16 MB FLASH - QCA9886 2T2R 5 GHz 802.11ac, 23 dBm - 12 dBi built-in antenna - POWER/LAN/WAN/WLAN green LEDs - 4x RSSI LEDs (2x red, 2x green) - UART (115200 8N1) Flashing instructions: The original firmware is based on OpenWrt so a sysupgrade image can be installed via the stock web GUI. Settings from the original firmware will be saved and restored on the new one, so a factory reset will be needed. To do so, once the new firmware is flashed, enter into failsafe mode by pressing the reset button several times during the boot process, while the WAN LED flashes, until it starts flashing faster. Once in failsafe mode, perform a factory reset as usual. Alternatively, the U-boot bootloader contains a recovery HTTP server to upload the firmware. Push the reset button while powering the device on and keep it pressed for >10 seconds. The device's LEDs will blink several times and the recovery page will be at http://192.168.1.1; use it to upload the sysupgrade image. Note: Four MAC addresses are stored in the "art" partition (read-only): - 0x0000: 40:A5:EF:AA:AA:A0 - 0x0006: 40:A5:EF:AA:AA:A2 - 0x1002: 40:A5:EF:AA:AA:A1 - 0x5006: 40:A5:EF:AA.AA:A3 (inside the 5 GHz calibration data) The stock firmware assigns MAC addresses to physical and virtual interfaces in a very particular way: - eth0 corresponds to the physical Ethernet port labeled as WAN - eth1 corresponds to the physical Ethernet port labeled as LAN - eth0 belongs to the bridge interface br-wan - eth1 belongs to the bridge interface br-lan - eth0 is assigned the MAC from 0x0 (*:A0) - eth1 is assigned the MAC from 0x1002 (*:A1) - br-wan is forced to use the MAC from 0x1002 (*:A1) - br-lan is forced to use the MAC from 0x0 (*:A0) - radio0 uses the calibration data from 0x5000 (which contains a valid MAC address, *:A3). However, it is overwritten by the one at 0x6 (*:A2) This commit preserves the LAN/WAN roles of the physical Ethernet ports (as labeled on the router) and the MAC addresses they expose by default (i.e., *:A0 on LAN, *:A1 on WAN), but swaps the position of the eth0/eth1 compared to the stock firmware: - eth0 corresponds to the physical Ethernet port labeled as LAN - eth1 corresponds to the physical Ethernet port labeled as WAN - eth0 belongs to the bridge interface br-lan - eth1 is the interface at @wan - eth0 is assigned the MAC from 0x0 (*:A0) - eth1 is assigned the MAC from 0x1002 (*:A1) - br-lan inherits the MAC from eth0 (*:A0) - @wan inherits the MAC from eth1 (*:A1) - radio0's MAC is overwritten to the one at 0x6 This way, eth0/eth1's positions differ from the stock firmware, but the weird MAC ressignations in br-lan/br-wan are avoided while the external behaviour of the router is maintained. Additionally, WAN port is connected to the PHY gmac, allowing to monitor the link status (e.g., to restart DHCP negotiation when plugging a cable).

* ath79: Correct glinet, gl-ar300m-lite in 02_networkJeff Kletsky2019-09-291-1/+1
| | | | | | | | | | | | | | Previously, the board name for the GL-AR300M-Lite was incorrect in 02_network, resulting in an unintended, fall-through condition when initializing the network configuration. While builds prior to commit 8dde11d521 (merged June 5, 2019) ath79: dts: drop "simple-mfd" for gmacs in SoC dtsi functioned properly, the error was noted in resolving first-boot connectivity issues related to the single-phy nature of the device and the "swap" of eth0 and eth1 related to that commit.

* treewide: fix hex2dec conversion for MAC address checksum offsetAdrian Schmutzler2019-09-291-2/+2
| | | | | | | | | | | | | | | | If chksum_offset is converted by $(($...)) at the beginning, the check [ -n "$chksum_offset" ] will always return true, as the conversion yields "0" for an empty argument, and [ -n "0" ] is true. With this patch, the variable is not converted before the check, but only when it's used in dd. No conversion is done for use in hexdump, as this can deal with hex value offsets.

* ath79: add support for Comfast E314N-v2Joan Moreau2019-08-092-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Taken code from https://patchwork.ozlabs.org/patch/884850/ that was never pushed by the author, and adapted to ath79. The Comfast E314N-V2 is a 2.4 GHz 2x2 radio with a built-in directional antenna and a second Ethernet port - very similar to the Ubiquiti NanoStation M2. The Ethernet port features a pass-through PoE capability, enabled or disabled with a slide switch. Specifications : - System-On-Chip: Qualcomm/Atheros QCA9531 - CPU/Speed: 650 MHz - Flash size: 8 MiB - RAM: 64 MiB - 2 Ethernet 1Gbp - 1 reset button - 1 switch to choose PoE from LAN or Wan. 48Vdc - Wifi 2.4 Ghz (b/g/n) - UART inside the box (3.3V, pins marked on the PCB) Firmware can be flashed on these units by the following method: 1.) Apply power to the unit 2.) Immediately AFTER applying power, hold down the reset button 3.) The WAN, LAN, and wireless lights will flash - wait three seconds (three flashes) and then release the button. 4.) After a second, the lights will flutter quickly and the unit will be visible at 192.168.1.1. A web page will be available to enable quick and simple uploading and flashing of firmware. During the boot process, these units also look for a tftp server at 192.168.1.10. If one is present, the firmware can be uploaded as a file called firmware-auto.bin Signed-off-by: Joan Moreau <jom@grosjo.net> [wrapped commit message - fix commit title capitalization] Signed-off-by: David Bauer <mail@david-bauer.net>

Notes: A. Audio stuff: 1. Since AR934x, all pins for peripheral blocks can be mapped to any available GPIOs. We currently don't have a PCM/I2S driver for AR934x so pinmux for i2s and SPDIF are bound to i2c gpio node. This should be moved into I2S node when a PCM/I2S driver is available. 2. The i2c-gpio node is for WM8918. DT binding for it can't be added currently due to a missing clock from I2S PLL. B. Factory image: Image contains a image header and a tar.gz archive. 1. Header: A 288 byte header that has nothing to do with appended tarball. Format: 0x0-0x7 and 0x18-0x1F: magic values 0x20: Model number string 0xFC: Action string. It's either "update" or "backup" 0x11C: A 1 byte checksum. It's XOR result of 0x8-0x11B Firmware doesn't care about the rest of the header as long as checksum result is correct. The same header is used for backup and update routines so the magic values and model number can be obtained by generating a backup bin and grab values from it. 2. Tarball: It contains two files named uImage and rootfs, which will be flashed into corresponding mtd partition. Writing a special utility that can only output a fixed binary blob is overkill so factory image header is placed under image/bin instead. C. LED The wifi led has "Wi-Fi" marked on the case but vendor's firmware used it as system status indicator. I did the same in this device support patch. D. Firmware Factory u-boot is built without 'savenv' support so it's impossible to change kernel offset. A 2MB kernel partition won't be enough in the future. OKLI loader is used here to migrate this problem: 1. add OKLI image magic support into uImage parser. 2. build an OKLI loader, compress it with lzma and add a normal uImage header. 3. flash the loader to where the original kernel supposed to be. 4. create a uImage firmware using OKLI loader. 5. flash the created firmware to where rootfs supposed to be. By doing so, u-boot will start OKLI loader, which will then load the actual kernel at 0x20000. The kernel partition is 2MB, which is too much for our loader. To save this space, "mtd-concat" is used here: 1. create a 64K (1 erase block) partition for OKLI loader and create another partition with the left space. 2. concatenate rootfs and this partition into a virtual flash. 3. use the virtual flash for firmware partition. Currently OKLI loader is flashed with factory image only. sysupgrade won't replace it. Since it only has one function and it works for several years, its unlikely to have some bugs that requires a replacement. Signed-off-by: Chuanhong Guo <gch981213@gmail.com>
