By default the scb_ver is "33" but it can be modified at runtime in order
to load the config for SCB v3.4 (i.e, load-lm32 rt_cpu.elf scb_ver=34)

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.

Even if it not a suggested configuration, having it in configs
help ./MAKEALL to build-test the ptp-noposix option, which is still alive.

Result of this script:

   for n in configs/*; do
      f=$(basename $n)
      make $f
      cp .config $n

This fixes a missing symbol and another minor header issue.  Needed to
build for wr-switch.
Signed-off-by: Alessandro Rubini <rubini@gnudd.com>

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.
