Tested on:
* Cloud Engines Pogoplug E02
* RaidSonic ICY BOX IB-NAS62x0
* Iomega Iconnect
Some users are avoiding to replace their bootloader, because of that add
support for second stage u-boot image. Having ubifs capable bootloader is
required in order to boot current OpenWrt trunk.
Sample ib62x0 commands for running second stage bootloader:
tftpboot 0x800000 uboot-kirkwood-ib62x0_second_stage/openwrt-kirkwood-ib62x0_second_stage-u-boot.img
bootm 0x800000
Sample ib62x0 commands for flashing second stage bootloader:
tftpboot 0x800000 uboot-kirkwood-ib62x0_second_stage/openwrt-kirkwood-ib62x0_second_stage-u-boot.img
nand erase 0x100000 0x100000 ; nand write 0x800000 0x100000 0x${filesize}
nand read 0x800000 0x100000 0x100000 ; bootm 0x800000
While at it include parallel build support, use alphabetic order of the boards
and introduce common OpenWrt configuration.
