mediatek: add support for BananaPi BPI-R4 board
Hardware -------- SOC: MediaTek MT7988A (4x Cortex-A73) RAM: 4 GiB DDR4 Flash: 128 MiB Winbond SPI-NAND MMC: 8 GiB eMMC *or* microSD (cannot be used both) ETH: 4x 1GE (1x WAN, 3x LAN) 2x SFP+ (10G, 5G, 2.5G, 1G) USB: on-board USB 3.2 4-port hub 1x USB 3.2 port (type A connector) 1x M.2 for 4G/5G modem 2x mPCIe for additional modems WiFi: optional MediaTek MT7996 Wi-Fi 7 module (using 2x PCIe gen3 x2 on the mPCIe slots and 12V power) Installation ------------ 1. Decompress and write the sdcard image to a micro SD card and use that to boot the R4 (both dip switches in upper position). 2. Use the bootloader menu accessible via the serial console to install to SPI-NAND. 3. Switch to boot from SPI-NAND and install to eMMC. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
