The Makefile was empty, this only adds the kconfig rules
and a default target that make silentoldconfig

Add the lines from the .gitignore found in bst-kconfig. As in the
previous commit, use bst-kconfig commit v2.6.34-4-g8168c0b

This is the combination of the following commits (oldest on top)
from wrpc-sw:

  89cdfcd added kconfig infrastructure, the trivial way
  5fda0c8 kconfig: use pathnames from Linux-2.6.34
  ab30804 kconfig: use 'Kconfig' as file name, not the bst-kconfig ones
  7c78880 kconfig: trivially write "WRPC" in place of "Linux Kernel"
  2c30cb4 kconfig: trivially fix most 'kernel' words in messages
  70eb3ba kconfig: add a configs/ directory and use it
  64cc10f scripts/kconfig: don't complain for default in choices

After picking them, I replaced all "WRPC" with "PPSi", and I removed
the configs/  files (unrelated to this project).

In practice, at this point we have the Kconfig infrastructure of
Linux-2.6.34, which I picked from the "bst-kconfig" package, which did
the extraction work.

One day I forward-ported this from v2.6.34 to v3.4, by applying a few
hundred kernel patches. While the final code was working, we decided
the port was not needed for wrpc-sw. Here in PPSi I keep the same version
we have in wrpc-sw.

As of this commit, the code is not used; the default configuration
file and Makefile targets are added in the next commits.

The v3.3 manual refers to specifics of v3.2 and earlier hardware, so
we have now a reference to that manual, and the actualy information is
removed because it would become wrong for sure, over time.

This fixes several minor issues with wr_mon. It changes the term.c interface,
bur wr_mon is the only user of it and term.h.

  - term: support b/w mode (no colors)
  - term: simplify termios setting, and don't do it on non-tty files
  - term: term_poll now does poll, so user input is handled quickly
  - term: exit on ctrl-C
  - term: don't fflush() on every cprintf
  - wr_mon: accept "-b" for "black and white"
  - wr_mon: fix buffering of stdout, fflush the whole screenshot
      (this results in much less flashing in the terminal window)
  - wr_mon: use \n where possible, not calculated positions
      (this simplified future addition of dynamic interface listings)
  - wr_mon: shrink output vertically, so in no-servo mode it fits 80x25
  - wr_mon: use term_poll, not explicit sleep
  - wr_mon: don't clear the screen at exit time

Before the cleaning was not done and the git tag was not taken into
account if modified without modifying any source.

The package will be named as following: <tag_name>-<date>_binaries.tar.gz
If the <tag_name> does not start with the "official" wr-switch-sw- prefix
a forced prefix 'wr-switch-sw-unof-' will be added.
Examples:
  * wr-switch-v3.3.1 => wr-switch-sw-v3.3.1-20130902_binaries.tar.gz
  * v3.1-rc1         => wr-switch-sw-unof-v3.1-rc1-20130521_binaries.tar.gz

Also replace the generated .bin in the binaries/ folder

undocumented hack to enable v3.3 lx240t scb on v3.2 miniBP only by
creating an empty file named /wr/etc/lx240t.conf. This is only
needed for v3.2 miniBP because they do not have the i2c chip and its
DIP switch to setup version.

When we had a pulldown on the i2c bus the device was okay because we
only check ack (0), now we first check if we have a pullup and then a
ACK.

This is a patch of patch applied to m4 library during buildroot compilation.
This error occurs with recent GCC version (4.7.3 on ubuntu 13.04).

It solve the error: "can't create directory '/dev/shm': Read-only file system"
when /etc/inittab want to create /dev/shm folder. 
This happens since FS is read-only.

Git revision can refer to the at91bootstrap repo itself used to generate
the patches (in this case .git exist) or to a parent repo (wr-switch-sw)
that we used with patches (In this case we need to pass git value using
exported variable) because no .git folder when creating the
at91bootstrap folder.

WR_INSTALL_ROOT and WR_LIB are folders to install library while using NFS.
They should only be used with install command and not during linking step
because they can be out of sync.

The HDL sources can be found in wr-switch-hdl repo with the tag wr-switch-htl-v3.3

On some swtiches the management port was not accessible, most likely
for wrong timing in overall setup.  Removing and re-loading the
usb gadget module seems to fix the problem.

v3.3 gateware has reduced number of global clocks by using regional clock nets
for first 4 GTX. Software needs to compensate additional delays.

In Grand Master mode it takes longer to lock PLLs to external source, therefore
HAL becomes ready later.
