* kernel: Add missing config option for kernel 4.14Hauke Mehrtens2019-01-281-0/+1
| | | | | | | | | | | | | Kernel 4.14.96 got the new configuration option CIFS_ALLOW_INSECURE_LEGACY which allows to deactivate support for old and insecure SMB versions like 1.0 and 2.0. Still allow these old SMB version and fix build problems which occurred because this option was not defined. This was found by build bot.

* cns3xxx: don't use invalid mask value for clock eventsKoen Vandeputte2019-01-281-2/+4
| | | | | | | | | | | | | According to a commit from kernel 4.18-rc3, it's not valid to use "cpu_mask_all" for clock events and it should be replaced in favor of "cpu_possible_mask" [1] This warning was seen when booting kernel 4.19 on a cns3xxx board. Let's fix it also here just to be safe.

* cns3xxx: use actual size reads for PCIe (4.19)Koen Vandeputte2019-01-281-0/+46
| | | | | | | | | | | | | | | | | | | | | upstream commit 802b7c06adc7 ("ARM: cns3xxx: Convert PCI to use generic config accessors") reimplemented cns3xxx_pci_read_config() using pci_generic_config_read32(), which preserved the property of only doing 32-bit reads. It also replaced cns3xxx_pci_write_config() with pci_generic_config_write(), so it changed writes from always being 32 bits to being the actual size, which works just fine. Due to: - The documentation does not mention that only 32 bit access is allowed. - Writes are already executed using the actual size - Extensive testing shows that 8b, 16b and 32b reads work as intended It makes perfectly sense to also swap 32 bit reading in favor of actual size. also backport this patch to kernel 4.19 Signed-off-by: Koen Vandeputte <koen.vandeputte@ncentric.com>

* mbedtls: Kconfig option to enable/disable debug functionsMichael Heimpold2019-01-272-10/+28
| | | | | | | | | | | | | | | | | | | | | This introduces a new Kconfig option to switch on/off mbedtls' support for debug functions. The idea behind is to inspect TLS traffic with Wireshark for debug purposes. At the moment, there is no native or 'nice' support for this, but at https://github.com/Lekensteyn/mbedtls/commit/68aea15833e1ac9290b8f52a4223fb4585fb3986 an example implementation can be found which uses the debug functions of the library. However, this requires to have this debug stuff enabled in the library, but at the moment it is staticly patched out. So this patch removes the static part from the configuration patch and introduces a dynamic config file editing during build. When enabled, this heavily increases the library size, so I added a warning in the Kconfig help section. Signed-off-by: Michael Heimpold <mhei@heimpold.de>

* build: dtc: Disable noisy warnings by defaultPetr Štetiar2019-01-271-1/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While helping with review and build testing of a few 4.19 pull requests, I've noticed, that dtc compiler in OpenWrt uses different options then upstream kernel, which is leading to a very noisy output[1]. It wouldn't be that bad per se, but a lot of such warnings aren't easily fixable so I think, that we should follow what upstream does and simply ignore^W silence those noisy warnings. So this patch tries to syncs dtc compiler flags with upstream kernel till version 4.19.13, disabling those warnings as they were added in upstream kernel: v4.6-rc1-2-gbc55398 dtc: turn off dtc unit address warnings by default The newly added dtc warning to check DT unit-address without reg property and vice-versa generates lots of warnings. Turn off the check unless building with W=1 or W=2. v4.11-rc2-11-g8654cb8 dtc: update warning settings for new bus and node/property dtc gained new warnings checking PCI and simple buses, unit address formatting, and stricter node and property name checking. Disable the new dtc warnings by default as there are 1000s. As before, warnings are enabled with W=1 or W=2. The strict node and property name checks are a bit subjective, so they are only enabled for W=2. v4.16-rc3-9-g4fd98e3 scripts: turn off some new dtc warnings by default The latest dtc update adds some new noisy warnings, so turn them off by default. Disable 'avoid_unnecessary_addr_size' and 'alias_paths'. They can be re-enabled by building with 'W=1'. v4.17-rc1-27-g74656b6 kbuild: disable new dtc graph and unit-address warnings dtc gained some new warnings for OF graphs and unique unit addresses, but they are currently much too noisy. So turn off 'graph_child_address', 'graph_port', and 'unique_unit_address' warnings by default. They can be enabled by building dtbs with W=1.

* kernel: Build: Split kmod-regmapHauke Mehrtens2019-01-2713-79/+101
| | | | | | | | | | | | | | | | | | | | | | | This reduces the needed modifications to the mainline Linux kernel and also makes the regmap package work with an out of tree kernel which does not have these modifications. The regmap-core is only added when it is really build as a module. The regmap-core is normally bool so it cannot be built as a module in an unmodified kernel. When it is selected by on other kernel module it will always be selected as build in and it also does not show up in $(LINUX_DIR)/modules.builtin as it is not supposed to be a kernel module. When it is not in $(LINUX_DIR)/modules.builtin the build system expects it to be built as a .ko file. Just check if the module is really there and only add it in that case. This splits the regmap package into multiple packages, one for each bus type. This way only the bus maps which are really needed have to be added. This also splits the I2C, SPI and MMIO regmap into separate packages to not require all these subsystems to build them, on an unmodified upstream kernel this also causes problems in some situations.

It uses the same hardware as the v3 variant, sharing the same FCC-ID. CPU: MediaTek MT7628 (580MHz) RAM: 64M DDR2 FLASH: 8M SPI WiFi: 2.4GHz 2x2 MT7628 b/g/n integrated WiFI: 5GHz 2x2 MT7612 a/n/ac ETH: 1x WAN 4x LAN LED: Power, WiFi2, WiFi5, LAN, WAN, WPS BTN: WPS/WiFi, RESET UART: Near ETH ports, 115200 8n1, TP-Link pinout Create Factory image -------------------- As all installation methods require a U-Boot to be integrated into the Image (and we do not ship one with the image) we are not able to create an image in the OpenWRT build-process. Download a TP-Link image from their Wesite and a OpenWRT sysupgrade image for the device and build yourself a factory image like following: TP-Link image: tpl.bin OpenWRT sysupgrade image: owrt.bin > dd if=tpl.bin of=boot.bin bs=131584 count=1 > cat owrt.bin >> boot.bin Installing via Web-UI --------------------- Upload the boot.bin via TP-Links firmware upgrade tool in the web-interface. Installing via Recovery ----------------------- Activate Web-Recovery by beginning the upgrade Process with a Firmware-Image from TP-Link. After starting the Firmware Upgrade, wait ~3 seconds (When update status is switching to 0%), then disconnect the power supply from the device. Upgrade flag (which activates Web-Recovery) is written before the OS-image is touched and removed after write is succesfull, so this procedure should be safe. Plug the power back in. It will come up in Recovery-Mode on 192.168.0.1. When active, all LEDs but the WPS LED are off. Remeber to assign yourself a static IP-address as DHCP is not active in this mode. The boot.bin can now be uploaded and flashed using the web-recovery. Installing via TFTP ------------------- Prepare an image like following (Filenames from factory image steps apply here) > dd if=/dev/zero of=tp_recovery.bin bs=196608 count=1 > dd if=tpl.bin of=tmp.bin bs=131584 count=1 > dd if=tmp.bin of=boot.bin bs=512 skip=1 > cat boot.bin >> tp_recovery.bin > cat owrt.bin >> tp_recovery.bin Place tp_recovery.bin in root directory of TFTP server and listen on 192.168.0.66/24. Connect router LAN ports with your computer and power up the router while pressing the reset button. The router will download the image via tftp and after ~1 Minute reboot into OpenWRT. U-Boot CLI ---------- U-Boot CLI can be activated by holding down '4' on bootup. Dual U-Boot ----------- This is the first TP-Link MediaTek device to feature a split-uboot design. The first (factory-uboot) provides recovery via TFTP and HTTP, jumping straight into the second (firmware-uboot) if no recovery needs to be performed. The firmware-uboot unpacks and executed the kernel. Web-Recovery ------------ TP-Link integrated a new Web-Recovery like the one on the Archer C7v4 / TL-WR1043v5. Stock-firmware sets a flag in the "romfile" partition before beginning to write and removes it afterwards. If the router boots with this flag set, bootloader will automatically start Web-recovery and listens on 192.168.0.1. This way, the vendor-firmware or an OpenWRT factory image can be written. By doing the same while performing sysupgrade, we can take advantage of the Web-recovery in OpenWRT. It is important to note that Web-Recovery is only based on this flag. It can't detect e.g. a crashing kernel or other means. Once activated it won't boot the OS before a recovery action (either via TFTP or HTTP) is performed. This recovery-mode is indicated by an illuminated WPS-LED on boot. Signed-off-by: David Bauer <mail@david-bauer.net>
