lantiq: add support for AVM FRITZ!Box 7362 SL
Hardware: - SoC: Lantiq VRX288 - RAM: Winbond W971GG6JB 1 Gb (128 MiB) - Flash: - SPI: 8 Mb (1 MiB) for bootloader and tffs - NAND: 1 Gb (128 MiB) for OS - xDSL: Lantiq VRX208 - WLAN: Atheros AR9381 - DECT: Dialog Semiconductors SC14441 Everything except FXS/DECT works (no drivers for AVM's FXS implementation with SC14441). Installation via FTP: 1. Use scripts/flashing/eva_ramboot.py to send initramfs-kernel.bin to the device when powering on. Standard AVM procedures with finding the correct IP address and the right moment to open FTP apply here (approx. 4 seconds on 7362SL). IMPORTANT: set lzma compression in ramdisk options, bootloader stalls when receiving uncompressed images. 2. Transfer sysupgrade.bin image with scp to /tmp directory and run sysupgrade 3. First boot might take a bit longer if linux_fs_start was set to 1, in that case the device will reboot twice, first time it will fail to load second kernel (overwritten by ubifs), set linux_fs_start to 0 and reboot. OpenWrt uses the entire NAND flash. Kernel uses 4 MiB and rootfs uses the rest of 124 MiB, overwriting everything related to FRITZ!OS - both OS images, config and answering machine/media server data. To return to FRITZ!OS, use AVM's recovery image. Signed-off-by: Danijel Tudek <danijel.tudek@gmail.com>v19.07.3_mercusys_ac12_duma
