Manual pages for hpc device drivers?

There seems to be no documentation at all for shared hpc drivers, like
hpcio &c.  And the source code is completely uncommented either.  It
would be extremely helpful if driver authors or people familiar with
the code put together some documentation on those.

I'm looking to add more hardware support for Jornada 680/690 and it
seems like all the infrastructure is already provided by these drivers
but I'd rather have at least some docs on how to use it.

In particular, pin function controller in SH7709 multiplexes some pins
into one gpio bit (controllable via another register) and in Jornada
680 it is necessary to use some of gpio bits for both input (one
function) and output (another function), so drivers need to flip the
control bit back and forth to access the pin they need via single
shared location.  Does hpcio* provides support for this (from a brief
look i don't think it does)?

Thanks in advance.

SY, Uwe

NetBSD/hpcsh gcc3 snapshot uploaded

I have uploaded a gcc3-based snapshot of NetBSD/hpcsh built from the
tree with some uncommitted fixes to make gcc3 itself and gcc3 world
work for/on sh3.

    ftp://ftp.netbsd.org/pub/NetBSD/misc/uwe/hpcsh-20030924-gcc331/

You can actually fit all the world on a 256MB CF and still have
*plenty* of room.  I currently run a slightly smaller world (no yp,
kerberos, docs/man/info, etc) built from the same sources.  It's under
85MB after just a little bit of manual trimming (like named, boot
server, etc).

One known broken thing is that /dev/ksyms doesn't work because ksyms
code makes assumptions about order of ELF sections that hpcboot.exe
violates.

It's not an official snapshot made from a "clean" tree, so it's under
"misc", not "arch".  Still I think it's useful for hpcsh users.  I'm
certainly very happy to have a tiny gcc3 all-dynamic world finally
working on jornada.

SY, Uwe
