This adds almost 800 bytes to all configurations, but removes
200 bytes from the gsi_defconfig.  This is because sdb-eeprom
is already managed with this library, and thus the commit is removing
a duplication.

It is not mandatory to actually register the tree, but it's
a good move for consistency.

Later we'll need to scan several devices, for example to look for a
mac address in carrier flash or eeprom. To do that we'll need to have
devices properly registered.

This costs 150 bytes of binary size in gsi_defconfig.

This makes the binary size 500 bytes bigger for gsi_defconfig
(the configuration already using the library) and strangely a little
smaller for etherbone_defconfig.

This allows stuff like

  ./MAKEALL spec_legacy_defconfig spec_sdb_defconfig

to choose your relevant configuration files alone.

We agreed, long ago, to have 128k on the spec, like GSI is
already doing. This changes the default in Kconfig and removes
specific settings in configs/*

If the host wants a consistent view (*if* it wants it), it
can wait for the sequence number to be even, read the lot and
then check it did not change.

If it is odd, it means the structure is being modified. If it changed
after reading it means a new modification started.

Not my invention: it's old stuff, though smart. See sequential locks
in the kernel for example.

"char valid" in a structure of integer makes alignment problems
(because we are accessing it from a different CPU we'd better not have
holes).

Also, there is no inherent consistency needed here, and this valid bit
is racy anyways. We could solve it with a sequence number, if any, but
let's avoid it altogether by now.

The global pointer is used by some special assembly instructions
that we are not using (i.e., the compiler is not generating them
for us, because we don't use PIC or other "strange" stuff.

So, we'd better remove an assignement in the linker script that makes
little sense (it must be a typo of some kind, in the dark ages of this
code base).

We finally agreed to not use ptp-noposix any more. This allows simplifying
the main loop and library functions, in the future.

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.

By default the scb_ver is "33" but it can be modified at runtime in order

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
	git describe --always --dirty
