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

The uart module in wrpc-sw is a superset of this one (it has vuart), but
all the registers are compatible.

The files were slightly different, but nothing substantial, mainly
because wrpc-sw evolved a little from its original form. By copying
those uart.[ch] we shorten the difference with no techinical change, even
if the binary file differs from the previous commit.

While we have no gpio.h in wrpc-sw, it's better to clarify this
header is for wr-switch.

This removes defs.h by copying the only two inlines into the only file
that uses them.

It also replaces uart.h with vuart.h, which is a compatible superset
(so now uart.c here and wrpc-sw are almost the same).

The commit replaces the linker script with the one in wrpc-sw, with
the only addition of the "mbox" section, which is still missing from
that script.

The only remaining differences are the configurable ram and stack sizes.

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

This applies the effect of the following wrpc-sw commits, limited
to arch/lm32.

   583ab27 build: move libs from ldscript to LDFLAGS
   a502f9d arch/lm32/ram.ld: provide mprintf if missing
   394d140 general: add copyright notes

Additionally, it copies over crt0.S and debug.S from wrpc-sw;
but the only change is white space.

Now the only remaining difference in arch/ is the linker script.

This matches commit "5d3fc51 compilation fixes" in wrpc-sw. At this
point the two arch/lm32 only differ in the linker script, that has an
mbox section in wr-switch-sw, missing in wrpc-sw.

This has no effect on rt_cpu.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.

Besides, the very short pps width was something we had to fix anyways.
Now it's 10ms as agreed (same as wrpc-sw).  This changes the generated
binary.

The addition of missing prototypes (now zeroing the diff for
softpll_ng.h between here and wrpc-sw) changes the binary being built,
but I assume we can feel safe about it.

Here I copy includes/std/ from wrpc-sw, and change hw includes
to be the same as in wrpc-sw.  I'm aware rt/include/stdint.h is
better than the new rt/include/std/stdint.h but that's it for now.

If static IP addressing is used (e.g. using wrboot), it makes sense
to provide a static DNS nameserver.  This option may be useful to
people building a single image to install several switches.

If the configuration string is empty (default) nothing changes (and
/etc/resolv.conf is a symlink to /tmp/resolv.conf, so a dhcp client
can work withint a read-only filesystem).

This is a verbatim copy of the current rsyslog.conf in buildroot.
The next commit fixes it for our needs, but I'd better save the

Most daemons write their stdout/err to /dev/kmsg, and thus clutter
the serial console. We'd better boot in quiet mode. This, among other
things, gains a few seconds of boot time.  Developers can always add
"verbose" if needed (or remove "quiet").

Developers may want to preserve the filesystem image, to verify the
effect of configuration options, avoiding the need to untar
images/wrs-image.tar.gz every time.

I personally used it to verify the next commits, other people may
prefer to keep it disabled.

THe previous version of the file was not working, both because
of a typo and because ppsi currently fails if wrsh_hal is not
ready.  This adds a polling loop to wait for the mini-rpc socket to
be available.
