* apm821xx: Force Ethernet PHYID on MX60/MX60WChristian Lamparter2018-04-131-1/+1
| | | | | | | | | | The MX60's uboot disables all the PHYs before starting linux. This causes the PHY/switch detection code to malfunction almost all of the time. To get around this, set a compatible flag to force PHYID. Signed-off-by: Christian Lamparter <chunkeey@gmail.com> Signed-off-by: Chris Blake <chrisrblake93@gmail.com>

| | | | | | | | | | | Don't select the firmware with the board file, it prevents an easy use of the -ct ath10k firmware. Select the firmware within the default packages instead. Remove the per device selection of the firmware now that it the firmware is selected by default. Signed-off-by: Mathias Kresin <dev@kresin.me>

VCC, TX, RX, GND (Square hole is VCC) WARNING: The serial port needs a TTL/RS-232 v3.3 level converter! The Serial setting is 115200-8-N-1. Tested and working: - Ethernet - 2.4 GHz WiFi (Correct MAC-address) - 5 GHz WiFi (Correct MAC-address) - Factory installation from WebIF - Factory installation from tftp - OpenWRT sysupgrade (Preserving and non-preserving) - LEDs - Buttons Not Working: - AP/Extender toggle-switch Untested: - Support on EX6100v2. They share the same GPL-Code and vendor-images. The 6100v2 seems to lack one 5GHz stream and differs in the 5GHz board-blob. I only own a EX6150v2, therefore i am only able to verify functionality on this device. Install via Web-Interface: Upload the factory image to the device to the Netgear Web-Interface. The device might asks you to confirm the update a second time due to detecting the OpenWRT firmware as older. The device will automatically reboot after the image is written to flash. Install via TFTP: Connect to the devices serial. Hit Enter-Key in bootloader to stop autobooting. Command "fw_recovery" will start a tftp server, waiting for a DNI image to be pushed.

Push image with tftp -4 -v -m binary 192.168.1.1 -c put <OPENWRT_FACTORY> Device will erase factory-partition first, then writes the pushed image to flash and reboots.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for 8devices Jalapeno. Specification: QCA IPQ4018, Quad core ARM v7 Cortex A7 717MHz 256 MB of DDR3 RAM 8 MB of SPI NOR flash 128 MB of Winbond SPI NAND flash WLAN1: Qualcomm Atheros QCA4018 2.4GHz 802.11bgn 2:2x2 requires special BDF in QCA4019/hw1.0/board-2.bin with: bus=ahb,bmi-chip-id=0,bmi-board-id=16,variant=8devices-Jalapeno WLAN2: Qualcomm Atheros QCA4018 5GHz 802.11a/n/ac 2:2x2 requires special BDF in QCA4019/hw1.0/board-2.bin with: bus=ahb,bmi-chip-id=0,bmi-board-id=17,variant=8devices-Jalapeno ETH: Qualcomm Atheros QCA8072 Gigabit Switch (1 x LAN, 1 x WAN) phy@mdio3: Label: eth0 gmac0 phy@mdio4: Label: eth1 gmac1 Installation instructions: Since boards ship with old version of LEDE installation is simple. Just use sysupgrade -n -F sysupgrade.bin Syuspgrade needs to be forced since OpenWRT uses DT detection in recent releases. If you get error that FIT configuration is not found during boot it is due to older U-boot used on your board. That is because 8devices used custom FIT configuration partition name as they internally had v1 and v2 boards. Only v2 boards are sold so now they are shipping boards with never U-boot using generic config@1 FIT partition name. Also for old uboot it is possible to force loading config@1 by changing uboot environment: setenv boot5 'bootm 0x84000000#config@1’ saveenv Signed-off-by: Robert Marko <robimarko@gmail.com>
* kernel: mtd: bcm47xxpart: improve handling TRX partition sizeRafał Miłecki2018-04-125-2/+197
| | | | | | | | | | | | | | This is important fix for flash parsing in some corner cases. In case of TRX subpartition with rootfs being aligned to the flash block size it was incorrectly registered twice. Detecting & registering it as a standalone partition was resulting in an incorrect "firmware" partition size and possibly broken sysupgrade. It wasn't noticed before because "rootfs" alignment depends on a kernel size. It can happen though - depending on the configuration and the kernel size.

| | | | | | | | | | | | | | | | | | | | | | | | The Zorlik ZL5900V2 is an unbranded clone of HAME MPR-A1/2. It is marketed as "3G Wi-Fi Router". Only the PCB has the model name "ZL5900V2" printed on it. Specifications: - Ralink RT5350F (360 MHz) - 32 MB RAM - 8 MB Flash - 802.11bgn 1T1R - 1x 10/100 Mbps Ethernet - 1x USB 2.0 (Type-A) - 5200 mAh battery The ramdisk image (not the squashfs sysupgrade image) can be flashed through the web interface (named "GoAhead") of the factory firmware. However, as the factory firmware does not cleanly unmount the rootfs before flashing, the device may hang instead of rebooting after successful write. Power cycling the device gets you in OpenWrt where the squashfs image may be flashed through normal sysupgrade procedure. Signed-off-by: Vianney le Clément de Saint-Marcq <code@quartic.eu>

* ramips: add dwr-512 jboot firmware configurationGiuseppe Lippolis2018-04-085-15/+19
| | | | | | | | | | | | | | | | | | | | | The previous fw version require the replacement of the stock bootloader with u-boot. This prevent an easy stock restore of the original fw. Now a proper fw util has been developed to manage the stock jboot bootloader. Therefore make sense have a fw image for the stock bootloader. The old fw configuration (u-boot) is not compatible with the new one and will not be supported anymore. So at the end 2 image can be generated: 1) factory image with jboot bootloader openwrt-ramips-rt305x-dwr-512-b-squashfs-factory.bin 2) sysupgrade image with jboot bootloader openwrt-ramips-rt305x-dwr-512-b-squashfs-sysupgrade.bin Signed-off-by: Giuseppe Lippolis <giu.lippolis@gmail.com>

This device has a recovery system that assign the ip addr of env variable "serverip" via dhcp to a pc, and the "ipaddr" value to itself. The recovery it's triggered by a not bootable firmware, or pressing the reset button during the bootloader startup (first 30 seconds). The recovery uses a http page to restore the firmware, and it's checking the firmware image header, so use the "factory" image to restore or the original firmware. You can access vendor firmware over serial using: - login: root - password: linuxrocks Image was tested only in EU version of the device, but should work also with the same device version sold in other countries.

* ramips: mt7620: eMMC: fix compiler warnings in non-debug modeAndré Draszik2018-04-042-40/+26
| | | | | | | | | | | drivers/mmc/host/mtk-mmc/dbg.c:51:13: warning: 'cmd_buf' defined but not used [-Wunused-variable] static char cmd_buf[256]; ^~~~~~~ In addition, msdc_reg[] is completely unused, even in debug mode. Signed-off-by: André Draszik <git@andred.net>
* ramips: mt7620: eMMC: remove unused variableAndré Draszik2018-04-042-8/+2
| | | | | | | | msdc_6575_host[] is unused, just remove it. Also, it was the source of memory corruption up until the previous fix to this driver. Signed-off-by: André Draszik <git@andred.net>
* ramips: mt7620: eMMC: stop invalid memory access if only one device is definedAndré Draszik2018-04-042-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pdev->id is -1 when only one device exists, and is used: * as an index into drv_mode[] to determine whether to use PIO or DMA mode (via host->id) * as an index into msdc_6575_host[], to store the mmc_priv() data. Obviously, -1 is not a valid index in either case, causing us to read invalid memory, and memory corruption, respectively. The invalid memory read is causing non-deterministic behaviour, in particular in the v4.4 kernel it still picked DMA mode, but in the v4.9 it now always picks PIO mode. Also, PIO mode doesn't work, causing the following: / # echo 3 > /proc/sys/vm/drop_caches [ 3845.249237] sh (128): drop_caches: 3 / # /root/usr/lib/libc.so [ 3846.096070] do_page_fault(): sending SIGSEGV to libc.so for invalid read access from 7f9cb5a0 [ 3846.104758] epc = 779b0ea4 in libc.so[7792f000+c3000] [ 3846.109907] ra = 779a8004 in libc.so[7792f000+c3000] Segmentation fault / # /root/usr/lib/libc.so musl libc (mipsel-sf) Version 1.1.16-git-40-g54807d47 Dynamic Program Loader Usage: /root/usr/lib/libc.so [options] [--] pathname [args] (i.e. initial page-in of any binary causes a segfault, subsequent access works.) While this change doesn't fix PIO mode, it at least makes us deterministically use DMA (which works), and it also stops us from corrupting memory. Signed-off-by: André Draszik <git@andred.net>
