Base debian-cd scripts for imx51 on new Freescale uboot
Over the last two releases we used redboot-tools to create images for imx51. Freescale moves the imx51 architecture to the uboot bootloader by default now. Image build scripts and userspace maintenance tools need to be moved to uboot to comply with this change.

Whiteboard
[asac 29-11-09] freescale support is important for us; also this would unblock unifying the cd image production (using uboot everywhere): Hence, marking as essential.
[asac 03-12-09] approved.
[asac 03-12-09] did some minor corrections with ogra to the package names that get demoted/promoted; all should be fine now.
[asac 08-01-10] postponing non essential stuff; remember: those are still opportunities for later this cycle.
[asac 13-01-10] postponing all not yet finished alpha-2 items and duplicating them below to somehow reflect that those items didnt get done in alpha-2 and moved to alpha-3 (e.g. added workload there) (lets cross finger the new work item software agrees!)
[asac 29-01-10] postponing alpha-3 items - this specs becomes optional for lucid; depends on usb support and uboot bug fixes whether we would consider it again
[asac 29-01-10] moving spec to beta-1 to keep it on the radar

blocked on uboot upstream bugs; decision: keep and update redboot for imx51
