PATCH 2/3 fs: add uimage support w/ example for cpio

From: Spenser Gilliland <[email protected]>

Adds uimage support for various root filesystems. Uimage support is needed when using the bootm command in uboot. This provides both a simple infrastructure similar to the current BR2_TARGET_ROOTFS_$(2)_GZ for adding compression. To define the a rootfs should have a UIMAGE wrapper simply create the BR2_TARGET_ROOTFS_$(2)_UIMAGE symbol.

PATCH 3/3 zedboard: add Avnet Zedboard support.

Hi,

Rather new in buildroot but already fond of it.
As a Zedboard user I would really appreciate to have this patch merged in BR mainline.

Good job!
