ath79: add support for Meraki MR12
Port device support for Meraki MR12 from the ar71xx target to ath79. Specifications: - SoC: AR7242-AH1A CPU - RAM: 64MiB (NANYA NT5DS32M16DS-5T) - NOR Flash: 16MiB (MXIC MX25L12845EMI-10G) - Ethernet: 1 x PoE Gigabit Ethernet Port (SoC MAC + AR8021-BL1E PHY) - Ethernet: 1 x 100Mbit port (SoC MAC+PHY) - Wi-Fi: Atheros AR9283-AL1A (2T2R, 11n) Installation: 1. Requires TFTP server at 192.168.1.101, w/ initramfs & sysupgrade .bins 2. Open shell case 3. Connect a USB->TTL cable to headers furthest from the RF shield 4. Power on the router; connect to U-boot over 115200-baud connection 5. Interrupt U-boot process to boot Openwrt by running: setenv bootcmd bootm 0xbf0a0000; saveenv; tftpboot 0c00000 <filename-of-initramfs-kernel>.bin; bootm 0c00000; 6. Copy sysupgrade image to /tmp on MR12 7. sysupgrade /tmp/<filename-of-sysupgrade>.bin Notes: - kmod-owl-loader is still required to load the ART partition into the driver. - The manner of storing MAC addresses is updated from ar71xx; it is at 0x66 of the 'config' partition, where it was discovered that the OEM firmware stores it. This is set as read-only. If you are migrating from ar71xx and used the method mentioned above to upgrade, use kmod-mtd-rw or UCI to add the MAC back in. One more method for doing this is described below. - Migrating directly from ar71xx has not been thoroughly tested, but one method has been used a couple of times with good success, migrating 18.06.2 to a full image produced as of this commit. Please note that these instructions are only for experienced users, and/or those still able to open their device up to flash it via the serial headers should anything go wrong. 1) Install kmod-mtd-rw and uboot-envtools 2) Run `insmod mtd-rw.ko i_want_a_brick=1` 3) Modify /etc/fw_env.config to point to the u-boot-env partition. The file /etc/fw_env.config should contain: # MTD device env offset env size sector size /dev/mtd1 0x00000 0x10000 0x10000 See https://openwrt.org/docs/techref/bootloader/uboot.config for more details. 4) Run `fw_printenv` to verify everything is correct, as per the link above. 5) Run `fw_setenv bootcmd bootm 0xbf0a0000` to set a new boot address. 6) Manually modify /lib/upgrade/common.sh's get_image function: Change ... cat "$from" 2>/dev/null | $cmd ... into ... ( dd if=/dev/zero bs=1 count=$((0x66)) ; # Pad the first 102 bytes echo -ne '\x00\x18\x0a\x12\x34\x56' ; # Add in MAC address dd if=/dev/zero bs=1 count=$((0x20000-0x66-0x6)) ; # Pad the rest cat "$from" 2>/dev/null ) | $cmd ... which, during the upgrade process, will pad the image by 128K of zeroes-plus-MAC-address, in order for the ar71xx's firmware partition -- which starts at 0xbf080000 -- to be instead aligned with the ath79 firmware partition, which starts 128K later at 0xbf0a0000. 7) Copy the sysupgrade image into /tmp, as above 8) Run `sysupgrade -F /tmp/<sysupgrade>.bin`, then wait Again, this may BRICK YOUR DEVICE, so make *sure* to have your serial cable handy.
