I'd still argue that the standard example in 'multi.its' should have

OK, this is your position then. I can only explain where we are
coming from: in the early days of U-Boot (well, PPCBoot by then)
resources were much tighter than today - look at the examples in the
README: a v2.4.4 Linux kernel image would be around 780 kB
uncompressed or 330 kB compressed. At this time it was considered a
waste of resources to have the gzip uncompression code in the boot
loader and again duplicated in the Linux kernel - so it was omitted
there and U-Boot would do all uncompression, also of the ramdisks.
Well, my point was that I couldn't see U-Boot ever handling this. But
this discussion got a bit confused, split into two threads...
I agree this is not standard any more, but it is still a valid use
case, I think. I know, I'm an old man ;-)
It *is* a valid use case. But for current kernels (if compression is
enabled), it might be faster to let the kernel unzip the content
directly to the memory location where it should reside in the end.
However, I don't have a strong opinion on these examples. I'll let the
maintainers decide :-)
Best regards,
Simon
