Add support for the Edgecore ECS4100-12PH, an 8-port 802.3bt PoE Gigabit Ethernet switch with 2 combo RJ45/SFP and 2 SFP ports. Hardware: * SoC: RTL8393M * RAM: 256MiB * Flash: 32MiB SPI-NOR * Ethernet: * 8x GbE RJ45 PoE (external RTL8218B) * 2x GbE RJ45 / SFP combo (external RTL8214FC) * 2x SFP (external RTL8214FC) * Console: RJ45 RS232 port on front panel * PoE: Nuvoton M0516 + 2x Broadcom BCM59121 PSE Installation via bootloader: * open serial console (baud rate 115200) * interrupt boot process by pressing any key during boot * boot the OpenWrt initramfs: # rtk network on # tftpboot 0x8f000000 /tftpboot/openwrt-realtek-rtl839x-edgecore_ecs4100-12ph-initramfs-kernel.bin # bootm * copy openwrt-realtek-rtl839x-edgecore_ecs4100-12ph-squashfs-sysupgrade.bin to /tmp and use sysupgrade to install it: # sysupgrade /tmp/openwrt-realtek-rtl839x-edgecore_ecs4100-12ph-squashfs-sysupgrade.bin Even though U-Boot claims the switch is based on the RTL8392M SoC, my device is based on the RTL8393M SoC. I have confirmed this by removing the heatsink, and the Linux kernel agrees with this. Therefore the DTS has the rtl8393_ prefix. Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>
