AFAIK the kernel supports multiple concatenated separately compressed
initramfs just fine, so it may still be useful to add a target which
builds a cpio with all modules inside and the rest can be then
concatenated.

What do you think?

compression should be none as the kernel would take of decompression.

Both U-Boot and barebox should warn about ramdisk compression property
that is != "none".
