ar71xx: generate recovery image for WNDR4300
Extended the Makefile to generate a working factory reset image for Netgear WNDR4300. The image uses UBI with two volumes squashfs (rootfs) and JFFS2 (rootfs_data). In order to make stock U-Boot happy, a fake rootfs image is placed into the last erase block of the kernel partition. Signed-off-by: Stefan Agner <stefan@agner.ch> [juhosg: - restore the NetgearNAND/initramfs macro, - remove unused {Squash,Ubi}fsTemplate macros, - remove board specific mtd options from CONFIG_CMDLINE, append the board specific ubi.mtd parameter to the kernel command line instead, - increase kernel partition size to 2MiB, - use board specific ini file for ubinize, - put jffs2 eof mark into the rootfs_data ubi volume, - use KDIR_TMP for temporary images, - use the squashfs-raw image, - increase kernel partition size to 2MiB, - use a local ubinize macro, - fix macro parameter comments, - put the fake rootfs into the last erase block of the kernel partition, - move Image/Build/NetgearNAND/buildkernel macro before define Image/Build/NetgearNAND, - don't use the wndr3700 utility, use '-M' parameter of mkimage to set the uImage magic, - use '-recovery' suffix for the generated image, it is only usable via the fw_recovery function of the bootloader, - update commit log] Signed-off-by: Gabor Juhos <juhosg@openwrt.org> SVN-Revision: 38655
