What we need from you is a way to use nrv2b compressed ELF images as payload. Please don't say that is impossible.
CONFIG_COMPRESSED_ROM_STREAM does exactly that.
You need to give it an uncompressed payload since it does compression on its own.
ARGH! Now that indeed explains things very well.
Attached is a patch to make LinuxBIOS support precompressed payloads. While the LinuxBIOS build system can compress payloads on its own, the OLPC build system benefits from delivering a precompressed (and size-checked) payload.
Although the patch modifies targets/olpc/rev_a/Config.1M.lb this has no effect on current OLPC buildrom because it checks out an earlier revision of LinuxBIOS. So it should be a safe to apply.
Ron - you'll have to decide if you want to apply this to LinuxBIO or not - and then we'll just use the new revision.
This scares me - I don't like that we can't easily control the behavior here without patches (that would have to be updated every time we change revisions).
