Daniel Golle ce7209bd21 mediatek: add build for MT7981 RFB ... Add build for the MTK3943 reference board for MT7981B+MT7976C. **Hardware specification:** - SoC: MediaTek MT7981B 2x A53 - Flash: various options - RAM: 256MB DDR3 - Ethernet: 4 x 10/100/1000 Mbps via MT7531AE switch EITHER 1 x 10/100/1000 Mbps built-in PHY OR 1 x 10/100/1000/2500 Mbps MaxLinear GPY211C - Switch: MediaTek MT7531AE - WiFi: MediaTek MT7976C - Button: RST, WPS **Flash instructions for SPIM-NAND:** - write *mt7981-rfb-spim-nand-preloader.bin to 'BL2' partition - write *mt7981-rfb-spim-nand-bl31-uboot.fip to 'FIP' partition - erase 'ubi' partition - reset board - create ubootenv and ubootenv2 UBI volumes in U-Boot - edit environment and set bootcmd, e.g. setenv bootconf 'config-1#mt7981-rfb-spim-nand#mt7981-rfb-mxl-2p5g-phy-eth1' setenv bootcmd 'ubi read $loadaddr fit; bootm $loadaddr#$bootconf' - load initramfs image via TFTP: setenv serverip 192.168.1.254 setenv ipaddr 192.168.1.1 setenv bootfile openwrt-mediatek-filogic-mediatek_mt7981-rfb-initramfs.itb saveenv ; saveenv tftpboot bootm $loadaddr#$bootconf - Now use sysupgrade to write OpenWrt firmware to flash. SNFI-NAND, SPIM-NOR and eMMC all work very similar, a bootable SD card image is also being generated. However, as the board I've been provided only comes with SPIM-NAND all other boot media are untested. Signed-off-by: Daniel Golle <daniel@makrotopia.org>		2023-09-21 10:15:08 +01:00
