If it looks like we need to run the code uncompressed from the ROM holler but for now I am going to assume we can compress everything. Among other things it greatly simplifies the linker scripts.
holler. I would like to have running-from-ROM as an option. Some of the people in the embedded space really want it.
How do we keep both options as a config-time possibility?
So far we don't have a real running-from-ROM option for the C code as we started copying the code segment along with the data segment to RAM, a while ago, when I reduced the skew between Ollies boot from DOC code and the rest of LinuxBIOS.
I have some trouble seeing where running-from-ROM is an issue when it only happens at boot time. But except for the problem of maintaining very divergent code paths I have nothing against it.
