apm821xx: increase WNDR4700's dtb+kernel partition to 3.5 MiB
This patch cleans and reworks the WNDR4700 dts to increase the now combined dtb+kernel partition to 3.5 MiB. This has become necessary due to the switch to GCC 7.3 and the ever increasing kernel binary size. The dtb+kernel partition was combined in order to finally fix the problem with out-of-sync device-trees. From now on, the kernel and device-tree will always be updated together. Upgrade Note: Existing installations will have to use the TFTP firmware recovery option in order to install the update. Affected users are advised to make a backup of their existing configuration prior to running sysupgrade: <https://openwrt.org/docs/guide-user/installation/generic.backup#backup_openwrt_configuration> Due to the repartitioning of the NAND, the generated backup should be placed on either the internal HDD, an attached USB-Stick or on another PC (externally). To manually trigger the firmware recovery, the reset button has to be pressed (and hold) during boot. U-boot will enter the "Upgrade Mode" and starts a tftpserver listening on 192.168.1.1 for a tftp client from one of the four LAN/Ethernet ports to connect and upload the new system: (enable tftp binary mode!). openwrt-apm821xx-nand-netgear_wndr4700-squashfs-factory.img Cc: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: Christian Lamparter <chunkeey@gmail.com>
