The previous version was compiled into a 64bit division
by gcc. in this way it uses no division, but a bitshift.

This reduces the compiled file by 4 bytes.

Some declaration was int8_t, some int32_t and some didn't match
the function definition. Now everything returns just int.
Anyway the functions return only 0 or -1, so there are no problems
returning int. Moreover in this way the resulting assembler is
smaller for every target architecture (even if here we always
build for lm32)

This reduces the binary by 30 bytes.

This adds 2.3kB to the GSI configuration, beause it enable ptpdump.
Earlier it was always forces off, due to wrong comparison of ram size.

This cleans a little the calibrator code: we'll write to eeprom only
when the measured value is different from the previous one.

With this commit, code is also slightly smaller (28 bytes).

This includes ppsi-v2014.07.

The new ppsi master is Kconfig-based, so our makefile must
make "wrpc_defconfig" in ppsi before building it.
Additionally, the link steps changed to the better in there, so we
don't link the "strange" $(PPSI)/proto-standard/libstd.a any more.

We may consider whether a local .config for ppsi should be
provided by this package instead of relying on its own choices;
not a big deal, though, as we maintain them at the same time.

Please note that any existent ppsi/.config is preserved, to allow
local tests. This should not have any impact on normal users.

KERNELVERSION variable from Linux was still used.
It was not initialized so the displayed version in the headers
of make gconfig and make menuconfig was missingor wrong.
It just said (null) or KERNELVERSION.
KERNELVERSION has been changed to VERSION all over the kconfig
scripts. Makefile.kconfig exports this variable so it can be
used by config scripts with getenv().
Now it prints the ppsi version with the present commit, like
diplayed from

This also removes an unsed function, that I found because it used
timer_delay().

We don't want "timer_delay(howlong)" because people won't know the
unit while looking at the header.

Also, this removes an unused prototype and adds void when void is due
in timer code.

ram.ld must be rebuilt every time the configuration changes. It was
supposed to be like that, but it was not.

So, the older ram.ld was used when first building with a new config,
and only the second time the rule was used. This was exposed by
failuers in ./MAKEALL where each configuration is built only once.

This fixes a missing symbol and another minor header issue.  Needed to
build for wr-switch.

This fixes the makefile to build either wrc.bin or rt_cpu.bin, using
the obj-y convention. At this point Kconfig can't select rt_cpu.bin,
and nothing changes in the ouput binary, in all configurations.

The commit is part of the effort in unifying softpll with
wr-switch-sw, and later remove the duplicated code there.

The files added by these commit are going to be built when configuring
wrpc-sw to build wr-switch rt_cpu (which is, basically, the softpll
code alone, with mini-rpc with the host and the basic glue code).  The
files are copied with the original name with two exceptions:

   wr-switch-sw::rt/main.c            becomes wrpc-sw::wrs_main.c
   wr-switch-sw::rt/arch/lm32/ram.ld  becomes wrpc-sw::arch/lm32/ram-wrs.ld

The files are copied from commit FIXME of wr-switch-sw.

This commit has no technical effect, as the files are not built for wrpc-sw.

softpll is built for both wrc and wrs; since it includes wrc.h and
syscon.h, we must make them suitable for both environments.

Waiting for the time and energies for a better merge, this uses ifdef
to differentiate the two cases: the timer code is different (different
prototypes) and the clock frequency is different as well (125 vs 62.5
MHz).

include/trace.h is different in wr-switch. This uses an ugly ifdef
to make wr-switch rt_cpu code build here unmodified.

This has no effect on wrc.bin: board.h is renamed into board-wrc.h
and included by the new board.h. The new board-wrs.h is copied from
wr-switch-sw/rt/include/board.h

This has no effect on wrc.bin. The commit unifies the directory
softpll/ between wr-switch and wr-node. No differences are left.

This is an ugly ifdef, but I prefer merging the code base (removing
duplicates) before addressing the configuration problem.
