realtek: add ZyXEL GS1900-24 v1 support
The ZyXEL GS1900-24 v1 is a 24 port switch with two SFP ports, similar to the other GS1900 switches. Specifications -------------- * Device: ZyXEL GS1900-24 v1 * SoC: Realtek RTL8382M 500 MHz MIPS 4KEc * Flash: 16 MiB * RAM: Winbond W9751G8KB-25 64 MiB DDR2 SDRAM * Ethernet: 24x 10/100/1000 Mbps, 2x SFP 100/1000 Mbps * LEDs: * 1 PWR LED (green, not configurable) * 1 SYS LED (green, configurable) * 24 ethernet port link/activity LEDs (green, SoC controlled) * 2 SFP status/activity LEDs (green, SoC controlled) * Buttons: * 1 "RESET" button on front panel (soft reset) * 1 button ('SW1') behind right hex grate (hardwired power-off) * Power: 120-240V AC C13 * UART: Internal populated 10-pin header ('J5') providing RS232; connected to SoC UART through a SIPEX 3232EC for voltage level shifting. * 'J5' RS232 Pinout (dot as pin 1): 2) SoC RXD 3) GND 10) SoC TXD Serial connection parameters: 115200 8N1. Installation ------------ OEM upgrade method: * Log in to OEM management web interface * Navigate to Maintenance > Firmware > Management * If "Active Image" has the first option selected, OpenWrt will need to be flashed to the "Active" partition. If the second option is selected, OpenWrt will need to be flashed to the "Backup" partition. * Navigate to Maintenance > Firmware > Upload * Upload the openwrt-realtek-rtl838x-zyxel_gs1900-24-v1-initramfs-kernel.bin file by your preferred method to the previously determined partition. When prompted, select to boot from the newly flashed image, and reboot the switch. * Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it: > sysupgrade /tmp/openwrt-realtek-rtl838x-zyxel_gs1900-24-v1-squashfs-sysupgrade.bin U-Boot TFTP method: * Configure your client with a static 192.168.1.x IP (e.g. 192.168.1.10). * Set up a TFTP server on your client and make it serve the initramfs image. * Connect serial, power up the switch, interrupt U-boot by hitting the space bar, and enable the network: > rtk network on > Since the GS1900-24 v1 is a dual-partition device, you want to keep the OEM firmware on the backup partition for the time being. OpenWrt can only be installed in the first partition anyway (hardcoded in the DTS). To ensure we are set to boot from the first partition, issue the following commands: > setsys bootpartition 0 > savesys * Download the image onto the device and boot from it: > tftpboot 0x81f00000 192.168.1.10:openwrt-realtek-rtl838x-zyxel_gs1900-24-v1-initramfs-kernel.bin > bootm * Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it: > sysupgrade /tmp/openwrt-realtek-rtl838x-zyxel_gs1900-24-v1-squashfs-sysupgrade.bin Signed-off-by: Martin Kennedy <hurricos@gmail.com>
