This adds ext2 support from U-Boot and stitches it into the partition stuff. It also upgrades the board definitions so they can define the path to look for in the ext2 filesystem being mounted. I used /boot/uImage.bin because this is already in use by the packaged kernel. We now mount, open and pull the kernel from ext2 in phase2.c if the kernel source defines it.
