* kernel: fix forwarding locally generated packages in bridge isolation patchDaniel Danzberger2018-02-052-2/+2

* ar71xx: add support for the MikroTik RB911-2Hn/5Hn boardsGabor Juhos2018-01-2211-3/+123
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch adds support for the MikroTik RB911-2Hn (911 Lite2) and the RB911-5Hn (911 Lite5) boards: https://mikrotik.com/product/RB911-2Hn https://mikrotik.com/product/RB911-5Hn The two boards are using the same hardware design, the only difference between the two is the supported wireless band. Specifications: * SoC: Atheros AR9344 (600MHz) * RAM: 64MiB * Storage: 16 MiB SPI NOR flash * Ethernet: 1x100M (Passive PoE in) * Wireless: AR9344 built-in wireless MAC, single chain 802.11b/g/n (911-2Hn) or 802.11a/g/n (911-5Hn) Notes: * Older versions of these boards might be equipped with a NAND flash chip instead of the SPI NOR device. Those boards are not supported (yet). * The MikroTik RB911-5HnD (911 Lite5 Dual) board also uses the same hardware. Support for that can be added later with little effort probably. Installation: 1. Setup a DHCP/BOOTP Server with the following parameters: * 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. The usable intramfs files are: - openwrt-ar71xx-mikrotik-vmlinux-initramfs.elf - openwrt-ar71xx-mikrotik-vmlinux-initramfs-lzma.elf - openwrt-ar71xx-mikrotik-rb-nor-flash-16M-initramfs-kernel.bin 2. Press the reset button on the board and keep that pressed. 3. Connect the board to your local network via its ethernet port. 4. Release the button after the LEDs on the board are turned off. Now the board should load and start the initramfs image from the TFTP server. 5. Upload the sysupgrade image to the board with scp: $ scp openwrt-ar71xx-mikrotik-rb-nor-flash-16M-squashfs-sysupgrade.bin root@192.168.1.1:/tmp/fw.bin 5. Log in to the running system listening on 192.168.1.1 via ssh as root (without password): $ ssh root@192.168.1.1 7. Flash the uploaded firmware file from the ssh session via the sysupgrade command: root@OpenWrt:~# sysupgrade /tmp/fw.bin Signed-off-by: Gabor Juhos <juhosg@freemail.hu>

This allows board specific setup routines to access the various fields of the information. It is useful for investigating the hardware option bits for example.

* ar71xx: add definitions for RouterBOARD hardware option bitsGabor Juhos2018-01-221-0/+26

These values can be used in board setup codes, to do different initialization sequences. The values were obtained from the RouterOS 6.41-rc38 patches. Additionally, introduce two helper functions what make the processing of the hardware options easy. Signed-off-by: Gabor Juhos <juhosg@freemail.hu>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch aligns the device-tree file with the latest guidelines. - No longer include qcom-ipq4019-ap.dk01.1.dtsi. This file is only partially upstream and therefore subjected to changes that might not be compatible with the board. As a result, the definitions from the file have been copied into this dts. - exclusively use decimal GPIO addresses. - reorganize the reserved-memory layout to waste less memory. There's no point in keeping the u-boot loader around. This should also make it possible to create an image that will boot with the original EVA/ADAM2 loader without needing to install the modified u-boot loader. And finally mark the "tz-apps" as reusable. There isn't a way to upload apps to the trust-zone in OpenWrt yet. But it might see some use in the future as a "secure" key-store/TPM. - sort the first-level nodes alphabetically. - sort nodes with an address by the address.

| | | | | | | | | | | According to console log during TP-Link TL-WR840N v5 OEM firmware update procedure 0x3e0000-0x3f0000 64kB "config" partition, which is used to store router's configuration settings, is erased and recreated again during every OEM firmware update procedure, thus does not contain any valuable factory data.

Rework the network code to only enable IRQ's again if NAPI agrees it's safe to do so. Also only re-enable IRQ *after* cleaning up the RX ring and re-enabling DMA, which otherwise resulted in ugly warnings regarding dirty page fragments. These popped up nearly immediately when building the kernel with O2 iso Os. --> Note that this change fixes stability issues, at the cost of ~8% throughput performance. While at it, also change the iface name being used in warning prints, making it more obvious: "switch%d" --> "cns3xxx_eth" The changes have been tested on 4 boards, each moving ~30TB of data Signed-off-by: Koen Vandeputte <koen.vandeputte@ncentric.com>
