This may be a stupid question, but is it possible to put kexec in the ROM, too? Yes, it consumes some space, but I'm curious if it would be possible.
not stupid at all. On OLPC that's how I did it originally.
OK, great. How big does kexec get when put in the ROM? Is there still enough room for a kernel in that case (1MB chip)?
I tried this briefly while working on the m57sli and s2891 additions to buildrom, and could not fit the kexec binary and lab in less than 1MB.
But I didn't investigate exactly how the kexec binary is built in buildrom, and there might be some more trimming of the kernel config that can be done.
Thanks, Ward.
