Denis Kalashnikov 695a1cd53c ath79: add support for MikroTik RouterBOARD 912UAG-2HPnD ... This board has been supported in the ar71xx. Links: * https://mikrotik.com/product/RB912UAG-2HPnD * https://openwrt.org/toh/hwdata/mikrotik/mikrotik_rb912uag-2hpnd This also supports the 5GHz flavour of the board. Hardware: * SoC: Atheros AR9342, * RAM: DDR 64MB, * SPI NOR: 64KB, * NAND: 128MB, * Ethernet: x1 10/100/1000 port with passive POE in, * Wi-Fi: 802.11 b/g/n, * PCIe, * USB: 2.0 EHCI controller, connected to mPCIe slot and a Type-A port -- both can be used for LTE modem, but only one can be used at any time. * LEDs: 5 general purpose LEDs (led1..led5), power LED, user LED, Ethernet phy LED, * Button, * Beeper. Not working: * Button: it shares gpio line 15 with NAND ALE and NAND IO7, and current drivers doesn't easily support this configuration, * Beeper: it is connected to bit 5 of a serial shift register (tested with sysfs led trigger timer). But kmod-gpio-beeper doesn't work -- we left this as is for now. Flashing: * Use the RouterBOARD Reset button to enable TFTP netboot, boot kernel and initramfs and then perform sysupgrade. * From ar71xx OpenWrt firmware run: $ sysupgrade -F /tmp/<sysupgrade.bin> For more info see: https://openwrt.org/toh/mikrotik/common.
