hi folks.
i recently changed the evbmarm/fdt code to avoid forcing the
'booted_device' to be set to something if it was already set
(in that case, by the raidframe "soft root" code).
i surveyed all the cpu_rootconf() implementations. there are
a lot, some are fixed but many are not.
i'm not planning on fixing any of these right now, though many
will use an idential patch (eg, all hpc{arm,mips.sh}, many of
the m68k/ppc/mips ports, use similar or identical code here
already), and some require thinking a little more about it
(eg, the sparc* ports set "booted_device" during autoconf when
the boot device is found in the tree.) however, here's the
list of them all and my vague notes.

cpu_rootconf problems. most of these only need to have eg
"if (booted_device) return;" added to a function usually
called findroot() or set_root_device():

- also checks RB_ASKNAME, which means no default will be set
(consider removing this check here)

- might need to avoid setting boot_args? few others too.

- both sparc/sparc64 set booted_device during autoconfig
when the device is found, matched with the ofw provided
boot path info.

these ones have an always-true test could be fixed:
evbmips/cavium
evbmips/gdium
evbmips/loongson
evbmips/malta
evbmips/rmixl
if (booted_device)
return;
if ((booted_device == NULL) && netboot == 0) {
