realtek: add support for Panasonic Switch-M8eG PN28080K
Panasonic Switch-M8eG PN28080K is a 8 + 1 port gigabit switch, based on RTL8380M. Specification: - SoC : Realtek RTL8380M - RAM : DDR3 128 MiB (Winbond W631GG8KB-15) - Flash : SPI-NOR 32 MiB (Macronix MX25L25635FMI-10G) - Ethernet : 10/100/1000 Mbps x8 + 1 - port 1-8 : TP, RTL8218B (SoC) - port 9 : SFP, RTL8380M (SoC) - LEDs/Keys : 7x / 1x - UART : RS-232 port on the front panel (connector: RJ-45) - 3:TX, 4:GND, 5:GND, 6:RX (pin number: RJ-45) - 9600n8 - Power : 100-240 VAC, 50/60 Hz, 0.5 A - Plug : IEC 60320-C13 - Stock OS : VxWorks based Flash instruction using initramfs image: 1. Prepare the TFTP server with the IP address 192.168.1.111 2. Rename the OpenWrt initramfs image to "0101A8C0.img" and place it to the TFTP directory 3. Download the official upgrading firmware (ex: pn28080k_v30000.rom) and place it to the TFTP directory 4. Boot M8eG and interrupt the U-Boot with Ctrl + C keys 5. Execute the following commands and boot with the OpenWrt initramfs image rtk network on tftpboot 0x81000000 bootm 6. Backup mtdblock files to the computer by scp or anything and reboot 7. Interrupt the U-Boot and execute the following commands to re-create filesystem in the flash ffsmount c:/ ffsfmt c:/ this step takes a long time, about ~ 4 mins 8. Execute the following commands to put the official images to the filesystem updatert <official image> example: updatert pn28080k_v30000.rom this step takes about ~ 40 secs 9. Set the environment variables of the U-Boot by the following commands setenv loadaddr 0xb4e00000 setenv bootcmd bootm saveenv 10: Download the OpenWrt initramfs image and boot with it tftpboot 0x81000000 0101A8C0.img bootm 11: On the initramfs image, download the sysupgrade image and perform sysupgrade with it sysupgrade <imagename> 12: Wait ~ 120 seconds to complete flashing Note: - "Switch-M8eG" is a model name, and "PN28080K" is a model number. Switch-M8eG has an another (old) model number ("PN28080"), it's not a Realtek based hardware. - Switch-M8eG has a "POWER" LED (Green), but it's not connected to any GPIO pin. - The U-Boot checks the runtime images in the flash when booting and fails to execute anything in "bootcmd" variable if the images are not exsisting. - A filesystem is formed in the flash (0x100000-0x1DFFFFF) on the stock firmware and it includes the stock images, configuration files and checksum files. It's unknown format, can't be managed on the OpenWrt. To get the enough space for OpenWrt, move the filesystem to the head of "fs_reserved" partition by execution of "ffsfmt" and "updatert". - On the other devices in the same series of Switch-M8eG PN28080K, the INT pin on the PCA9555 is not connected to anywhere. Back to the stock firmware: 1. Delete "loadaddr" variable and set "bootcmd" to the original value on U-Boot: setenv loadaddr setenv bootcmd 'bootm 0x81000000' on OpenWrt: fw_setenv loadaddr fw_setenv bootcmd 'bootm 0x81000000' 2. Perform reset or reboot on U-Boot: reset on OpenWrt: reboot Signed-off-by: INAGAKI Hiroshi <musashino.open@gmail.com> Reviewed-by: Sander Vanheule <sander@svanheule.net>
