26869ad14c [PowerPC] Allow traversal of oversize OF properties.
In standards such as LoPAPR, property names in excess of the usual 31
characters exist.

This breaks property traversal.

While in IEEE 1275-1994, nextprop is defined explicitly to work with a
32-byte region of memory, using a larger buffer should be fine. There is
actually no way to pass a buffer length to the nextprop call in the OF
client interface, so SLOF actually just blindly overflows the buffer.

So we have to defensively make the buffer larger, to avoid memory
corruption when reading out long properties on live OF systems.

Note also that on real-mode OF, things are pretty tight because we are
allocating against a static bounce buffer in low memory, so we can't just
use a huge buffer to work around this without it being wasteful of our
limited amount of 32-bit physical memory.

This allows a patched ofwdump to operate properly on SLOF (i.e. pseries)
systems, as well as any other PowerPC systems with overlength properties.

ccfb965433 Add META_MODE support.
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

458e5419e6 - Add a reference to eeprom(8).
- Spell Open Firmware as "Open Firmware", the way it's done on
  OpenFirmware.org.

8cc2c16287 - Change ofwdump(8) to use sysexits(3) exit codes.
- Make the code use the new OFIOCMAXVALUE instead of defining the maximum
  length of property values locally.
- Move the application specific parts from ofw_util.c to ofwdump.c in
  order to make ofw_util.c more library-like. While ofw_dump_properties()
  could be made non-specific to ofwdump(8) it's currently optimized for
  use in ofwdump(8) and making it a library-like function would just
  complicate the code unnecessarily.
- Minor clean-up in ofw_util.c, e.g. make its use of getopt(3) the way
  it's described in style(9), make its usage() static, etc.
- Add a comment in ofw_util.c about why it doesn't call usage() when
  neither the "-a" option nor a node-name where given.
- Add ofw_optnode() and ofw_setprop(), helper functions for the
  OFIOCGETOPTNODE and OFIOCSET ioctls respectively, to ofw_util.[c,h].
- Be consistent with the use of 'const' in ofw_util.[c,h] and add 'const'
  to the function arguments that are acutally const but weren't declared
  as such.
- Mark WARNS=6 clean.

1b6eef5b4e Add a utility to examine the OpenFirmware device tree (on sparc64). This
allows access to detailed machine configuration information, and should
be especially useful to gather information for driver-related bug
reports.
