[ptxdist] [PATCH v3] Add flashbench tool

[Bernhard Walle <bernhard@bwalle.de>]

From: Bernhard Walle <walle@corscience.de>

This patch adds the flashbench tool from Linaro Project
git://git.linaro.org/people/arnd/flashbench.git. See also
http://lwn.net/Articles/428584/. Because there is no tarball, I
exported the current git repo and put it on my server.

The default maximum buffer size of 64 MiB (the buffer is allocated 4
times) was too large for my device, so I patched the tool and added an
option in the ptxdist menu.

Tested with a custom OMAP3 board which is similar to the Devkit8000.

v3: - Use menuconfig instead of config.
    - Change PTXCONF_FLASHBENCH_MAX_BUFSIZE to megabyte.
v2: - Correct URL (FIXME) in rules/flashbench.in.
