While I agree in principle with Scott's point that it would be good to 
understand and fix/improve the ARM bootm_linux_fdt() function, I have 
bought into Dave's argument that this is a useful environment variable 
and is symmetric with "initrd_high".

Consequently, I've added this patch to the u-boot-fdt repo.  If anyone 
has strong objects, now is the time to object strongly. ;-)

Thanks,
gvb
