These instructions are for 64-bit load/store. On ARMv5TE, the CPU
requires addresses to be aligned to 64-bit. When misaligned, behavior is
undefined (effectively either loads the same word twice on LDRD, or
corrupts surrounding memory on STRD).
On ARMv6 and newer, unaligned access is safe.
Removing these instructions for ARMv5TE is necessary, because GCC
ignores alignment information in pointers and does unsafe optimizations
that have shown up as bugs in various places.

Tested on:

* 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.
