Dear Michael Spang,

For ARM, the CONFIG_SKIP_LOWLEVEL_INIT option implies that the cpu_init_crit and lowlevel_init assembly functions are skipped. We may want to skip only lowlevel_init, so rename the option that skips both to CONFIG_SKIP_CPU_INIT_CRIT. The MIPS option of the same name is not renamed.
This is an inconsistency between architectures which I dislike.
Also, what in case we should want to skip only cpu_init_crit and not lowlevel_init? If we need to handle these separately, then we need 2 CONFIG options.
The CPU initialization is idempotent, so I can't think of a reason why it would be required to skip it. So, we might be able to change CONFIG_SKIP_CPU_INIT_CRIT to CONFIG_SKIP_LOWLEVEL_INIT in most cases. I'm just hesitant to do so because I don't have a variety of boards to test on.
