Add board support for the BananaPi BPI-R4 router board, based on the MediaTek MT7988A (Filogic 880) SoC with quad-core Cortex-A73 CPU. The BPI-R4 is the successor to the BPI-R3 but uses entirely different silicon: the internal switch runs at 2.5 GbE per port, the two SFP+ uplinks use native USXGMII at up to 10 Gbps, and WiFi is provided by a MediaTek MT7996E PCIe module supporting tri-band WiFi 7 (2.4/5/6 GHz). Two board variants, BPI-R4-2g5 and BPI-R4P, replace one SFP+ cage with a 2.5 GbE RJ45 port (using the MT7988A internal 2.5G PHY); the R4P adds an optional PoE daughterboard on that port. Both use the upstream mt7988a-bananapi-bpi-r4-2g5 device tree. Interfaces: - Standard R4: eth1 (gmac1/sfp2 LAN cage) → sfp2, eth2 (gmac2/sfp1 WAN cage) → sfp1 - R4-2g5/R4P: eth1 (2.5G PHY) → wan, eth2 (gmac2/sfp1 WAN cage) → sfp1 Factory reset / WPS button (GPIO14, active-low): detected by U-Boot at boot for factory reset; reused by Linux as KEY_WPS_BUTTON at runtime. eMMC install note: the MT7988A eMMC (pins 38-49) and SD card (pins 32-37) use separate physical pads so there is no electrical bus sharing, unlike some BPi-R3 configurations. However, a single MMC controller (mmc@11230000) handles both, so only one is active per boot session. The eMMC install procedure therefore still requires an intermediate SPI NAND bootloader step until a Linux-side install path is tested. SD card build (bpi_r4_sd_boot_defconfig) now uses the new mt7988a_bpir4_sd U-Boot defconfig with cap-sd-highspeed enabled, giving 50 MHz SD transfers instead of the previous 25 MHz legacy mode. Also adds MT7988/MT7996 firmware support to the buildroot linux-firmware package, for 2.5 GbE port PHY and WiFi7 extension board, and updates the aarch64_defconfig, aarch64_minimal_defconfig, the arch README, CI boot/image workflows, mkimage.sh, and the ChangeLog.

Welcome to Infix, your immutable, friendly, and secure operating system! On these pages you can find both user and developer documentation.
Most topics on configuring the system include CLI examples, but every setting, as well as status read-back from the operational datastore, is also possible to perform using NETCONF or RESTCONF. In fact, the Infix regression test system solely relies on NETCONF and RESTCONF.
Tip
The CLI documentation is also available from inside the CLI itself using the
helpcommand in admin-exec mode.
