Actually, I think it's better to use SD card images where possible.
- If you're using it just for experimentation, then the SD card is a much more
flexible and less risky way to experiment. Personally, I even prefer
kernel-linked-with-initramfs (and DTB) images, since that's just a single file
and it automatically gives you the rest of the SD card as a FAT partition.
- If you want to use it for an actual product (prototype), then you're anyway
going to have to study in a bit more detail how the flash works and you'll
probably want to do a slightly more complicated flash partitioning.
That said, I do think it's really useful to have those tcl scripts for using
SAM-BA.
And of course, since I never use the defconfigs myself, my opinion is probably
not that important.

Arnout
