Will those of us not interested in a single kernel binary that works everywhere be able to configure an ARM kernel image without a lot of bloat?
I'm not aware of increase in code size from the single kernel image yet. If you find something, let us know.
I have been assuming that the device tree conversion added a small overhead to both the kernel size and the boot time. You are correct that I should measure this before complaining. :-) I'll try to do that when I have some time. Unfortunately, before and after size snapshots are a little difficult to obtain -- it appears that support for device tree involves other refactoring.
My main issue is to avoid requiring the loading of drivers and features that are not required for a platform, if the platform does not need it (or the developer chooses to omit it). I may have mis-read this thread, but it sounded like the uncompress code was going to be moved to a common area and not be configurable.
Sorry if this is not the case.
