LPC2888 board. The allocator used is dlmalloc, just as in Newlib, but it's a
newer version than can handle non-contiguous memory spaces (2.8.3, as opposed
to 2.6.4 in Newlib 1.16.0, I really have no idea why they're using such an
ancient version of dlmalloc). To use it add "allocator=multiple" to your scons
command line (default for LPC2888).
This takes care of my LPC2888 board (any many other board out there)
that have RAM both on the CPU itself and on a separate chip.
To use it add "allocator=tlsf" to your scons build command.
Even though the code for all the platform was modified, the new code
should not modify the "old" allocator behaviour.
Also added a new "mem" command to the shell, it gives information about
the current RAM state (total, used, free).
NOT YET TESTED !!! So use with care.
* platform()/cpu() returns the platform/cpu name, respectively
(instead of previously name()/cpu())
* platform interface is platform_pd_get_<cpu/platform/cpu_clock>
pd.name() is still defined to keep compatibility with samples on the
web site. It would be best for sample programs to be part of the repository
so they could be kept aligned with the code they demonstrate.
