There's no one embedded setup on any platform, but one of the few
constants of embedded development is trying to eliminate unnecessary
requirements.
Just on standard-ish PC hardware I've seen people try to stick Linux in the
BIOS flash (generally not enough room), I've seen people try to stick
it as the first stage PXE payload, there's the fun and games with
kexec of emergency kernels for crash dumps...
If the capability to skip an unnecessary bootloader was available, people
would use it.
