Hi Tom, Hi Stefan, I've trimmed down the CC list a bit.

In that, I can take care of 15 boards (1 Armada XP and 14 Kirkwood). - 10 boards with trivial changes (just remove JFFS2 from defconfigs) configs/dns325_defconfig:CONFIG_CMD_JFFS2=y configs/dockstar_defconfig:CONFIG_CMD_JFFS2=y configs/goflexhome_defconfig:CONFIG_CMD_JFFS2=y configs/guruplug_defconfig:CONFIG_CMD_JFFS2=y configs/iconnect_defconfig:CONFIG_CMD_JFFS2=y configs/nas220_defconfig:CONFIG_CMD_JFFS2=y configs/nsa310s_defconfig:CONFIG_CMD_JFFS2=y configs/nsa325_defconfig:CONFIG_CMD_JFFS2=y configs/pogo_v4_defconfig:CONFIG_CMD_JFFS2=y configs/pogo_e02_defconfig:CONFIG_CMD_JFFS2=y - Four boards (actually 2 boards, openrd has 3 variations) need convert to bootstd and remove JFFS2 configs/openrd_base_defconfig:CONFIG_CMD_JFFS2=y configs/openrd_client_defconfig:CONFIG_CMD_JFFS2=y configs/openrd_ultimate_defconfig:CONFIG_CMD_JFFS2=y configs/sheevaplug_defconfig:CONFIG_CMD_JFFS2=y - One board needs to remove legacy boot sequence and remove JFFS2 (bootstd already done) configs/ds414_defconfig:CONFIG_CMD_JFFS2=y Hopefully someone will take care of the 12 remaining boards. All the best, Tony
