In general, Linux is not set up to run this way. The Linux kernel
normally assumes that some level of hardware initialization has taken
place before it starts to run. Also, few Linux kernels support XIP
(execute in place) from ROM/FLASH.
Also, having RedBoot in place provides much richer control over the
startup process. By using boot-time scripts, you can start your Linux
kernel, pass initialization options, etc.
Is there some particular platform you want to do this on?
Why is the current [boot-time scripting] in RedBoot not adequate?
