That's not that difficult. For example, U-Boot both supports the features of "protected RAM" (that can, for example be used for a pramfs file system) and a shared (between U-Boot and Linux) log buffer. Especially the shared log buffer has been pretty useful to us in a couple of projects - we can, for example, pass U-Boot POST results up to the Linux kernel where applications can pick up the information using standard syslog mechanisms; and after a Linux crash, we can either read the log buffer in U-Boot, or just leave it as is and pass it to the next booting kernel. That way you can at least see the crashdump etc. once the system is back up and running.
