I agree - if we're going to lzma, no need for the intermediate step.
Also, when I did measure it, I found that
the size of (bzImage + gzip'ed initrd) was smaller than (nrv2b
compressed mkelfimage output with vmlinux and initrd). Maybe something
changed, but I would like to see the numbers one more time on final
output. So do a buildrom pass and let me know what you're seeing on olpc
.elf file vs. what you are doing. Final numbers of the payload, I mean.
nrv2b(vmlinux + initrd.uncompressed):
Payload 808426 (76310 bytes free in ROM)
bzImage + initrd.gz:
825175 bytes (59561 bytes free in ROM)
Thats a delta of 16k.35 Kbytes.

but we still need to size the delta in linuxbios for using decompressor.
