NEC Mobilepro880 doesn't boot with current or netbsd-4

Hello all.

I grabbed kernels from these places:

ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-daily/netbsd-4/200701
170000Z/hpcmips/binary/sets/kern-GENERIC.tgz
ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-daily/HEAD/2007011500
00Z/hpcmips/binary/sets/kern-GENERIC.tgz

Both do not boot. They do boot in an emulated environment
using
gxemul, however I noticed that the hardware isn't discovered
the same
way as on my real hardware so I don't know if that's
relevant.

They do boot on my Mobilepro790 however. I just plug this
exact same
CF card into it, and it boots just fine.

Here's the last few lines I get (typed by hand, if more is
needed let me know):

mqvideo0: framebuffer address: 0xaa0ea600
trap: TLB miss (load or instr. fetch) in kernel mode
status=0x2, cause=0x8008, epc=0x80297568, vaddr=0

80235704+3f4 (8037bb60,109,0,101) ra 0 sz 0
User-level: pid 0.1

Again, the above output is from this kernel:

ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-daily/HEAD/2007011500
00Z/hpcmips/binary/sets/kern-GENERIC.tgz

Any help would be appreciated.

there is a bug in MQ200 initialization.
Disable MQ200 from kernel configration. 

src/sys/arch/hpcmips/dev/mq200machdep.c:

void
mq200_mdsetup(struct mq200_softc *sc)
{
        const struct mq200_md_param *mdp;

        sc->sc_md = NULL;
        for (mdp = machdep_params; mdp->md_platform !=
NULL; mdp++) {
                                   ~~~~~~~~~~~~~~~~~~~~~~~~

good!

please submit PR.

solution:

mdp->md_platform != NULL; mdp++) {

 0. add 'NULL' value on initialize mdp->md_platform. 
 1. set mdp->md_platform initialize paramater for
not-tested machine.
   current status: MC-R530 ok

~~~~~~~~~~~~~~~~~~~~~~~~

I did this in the GENERIC config file:

##mqvideo*      at vr4102ip? addr 0x0a000000 size 0x800000  
   # MQ200 video
##hpcfb*                at      mqvideo?

Recompiled and it worked. X still works as well.

Should I submit a PR? I'm not sure what the code snippet you
posted
actually does so I don't know how to fix it...

Thanks!

Andy
