It looks very similar to what I'm using, including the rootfstype= part. 
The only bit I think may need a change is the ext2load which I think 
needs to be:
	ext2load mmc 1:1 0x32000000 boot/uImage\;
For the second partition it would be 1:2. Depending on what your 
${sd_image_name} is you may be ok to leave it, but I prefer defining it 
explicitly for each partition.
