Use true/false for if, not 1/empty, because "0" would return true
and it would be mileading (no bug is there, just potential)

rsyslogd forks and daemonizes by default. So we can't "respawn" from
inittab. The option to avoid forking also prints massive diagnostic
information, so let's fire it once only.

This also adds the default configuration file for ppsi.  It has no
effect, because it's the default that would apply if no configuration
file is there, but it's useful as a reference, and to ease editing.

We have to try until 10MHz and 1-PPS is there in GrandMaster mode.
Otherwise we won't have timing at all.

This variable, if not empty, allows to rebuild buildroot
in the previous build place, thus avoiding most build time.
This is useful for me when I just add packages and don't need
to recreate the compiler from scratch.

Well, so it is documented in the commit message.

During the rebase of branch "http-management" I dealt with some conflicts,
and CONFIG_RSYSLOG was lost in the buildroot config. This adds it back.

Running "ifup eth0" if eth0 is configured for dhcp would make the
client try a little while and then give up. Thus, if the dhcp server
is currently down we end up without IP address. This happens after a
power failure, if the switch reboots faster than the dhcp server.

Also, avoid ifplugd, that won't help in this case (the link is up,
so no "link up" will happen later.

This new configuration works in all cases:
     - eth0 is configured with a static address in /etc/network/interfaces
     - dhcp-driven, and link goes down and then up
     - dhcp-driven, and server not ready at boot time
     - dhcp-driven and all fine since boot time

The original ifplugd.action used "exec" improperly. Also,
we should not force "ifconfig eth0 down" when link down is detected,
or it will bever come up again.

Fix both items, even if we are not going to use ifplugd any more in
the next commit.

it really looks like ifplugd is not reading this file, so overwrite
the default one with an empty file, to avoid our users the effort to
track its use. The file is not empty, actually, but include this

By now, code here and in wrpc-sw is the same. The binary
built there is working, so let's pick that one. It
can be rebuilt in wrpc-sw by running

  make wr_switch_defconfig

The exact commit used to build what you have in binaries/ (or
in /wr/lib/firmware/rt_cpu.bin in the target system) can be
easily retrieved by extracting the commit name. For this binary:

   morgana% strings binaries/rt_cpu.bin | grep wrpc
   wrpc-v2.1-for-wrnic-19-g566aa53

This copies over pp_printf from wrpc-sw, builds it, and changes
trace.h to explicitly call pp_printf. Actually, it also
define mprintf to pp_printf.

The excplicit call is needed, or the --gc-functions will discard the
pp_printf code if no object file refers to it.  Later,
arch/lm32/ram.ld redirects mprintf to pp_printf, but that would be too
late.

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.

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.
