ppsi for wrs requres locks in shmem when shmem is changing. Since servo is
shared between wrs and wrpc fixes had to be implemented.
Since there is no shmem in wrpc, dummy function for locking had to be added.
As a side effect include/libwr/shmem.h was added.

Done as a part of work to move hal to shm in wrs.

Done in this commit:
--use wrpc_get_port_state instead of halexp_get_port_state
--make wrpc_get_port_state fill hal_port_state structure in the way how HAL
  fills shmem.
--update lib/net.c to use struct hal_port_state instead of hexp_port_state_t
--update monitor/monitor_ppsi.c to use struct hal_port_state instead of
  hexp_port_state_t
--update ppsi to get needed changes

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.

[t24-fix]: rewritten RX timestamp linearization (phase + counter merging) algorithm to be easier to understand.

For more info, check the note in the Documents section of the wrpc-sw project on ohwr.org.

After subtraction of transition value from linearized phase, the phase value was renormalized to 0...clock_period-1, but
not the other counters. This resulted in very rare 8ns jumps.

Wesley W. Terpstra authored 11 years ago and Grzegorz Daniluk committed 11 years ago

The phase was used backwards. Somehow this cancelled out the systematic
error introduced by the actual bug (wrong phase offset). When both bugs
are fixed the code seems to work every time.

This adds a real usleep implementation. The init function calculates
the "loops per jiffy" variable, by watching the timer ticks before
interrupts are enabled by spll_init().  This init takes 40ms.

Then, the udelay runs the same loop used in calculating lpj, and
is thus correct (it will be slower because we have interrupts running
at run time, but this is not a problem).

This is a copy of ptp-noposix/libposix/freestanding-wrapper.c, moved
into this project because it actually is only used here. The Makefile
now builds this one.

This move is needed in order to remove this faulty usleep and provide a
better one, while keeping the other fake functions called by ptp-noposix
code.

mprintf is of uncertain copyright status, and that's why
we added pp_printf (actually, that's why I picked pp_printf
fro ptp-proposal and made it a standalone thing).

Now that everyone involved confirms pp_printf is well tested,
let's remove mprintf.  We still accept mprintf in the callers,
because the name is used by our ptp-noposix submodule, and I'm
sure people has it in their fingers and it will appear again.

This adds copyright notes to all non-trivial source files,
unless they where already there (i.e. dev/endpoint.c alone).

I found authorship using the following script, run on commit "a2721762


documentation updated" (i.e, before automatic reindentation and other
trivial stuff by me):

  git grep -l . | grep -v sockitowm/ | \
  while read F; do
       echo "##### $F"
       git blame -w $F | \
         sed -e 's/^[^ ]* .//' -e 's/-[0-9][0-9]-[0-9][0-9] .*$//' | \
         sort | uniq -c | sort -rn
  done

Then I augmented each file with this boilerplate:

Then I removed all the lines that didn't apply. Sometimes I reordered
the authors to reflect who is the main author.

This is massive: 4k lines changed (but only 840 if you ignore
space-only changes).  In this case "git blame -w" won't always find
the right patch, and it may fall on this patch -- because those
800 lines changed in content too.

This has been done with

   find . -name '*.[ch]' | xargs -n 1 ./scripts/Lindent

Statistics: all changes and ignoring blank space:

   morgana% git diff --stat HEAD~1 | tail -1
    77 files changed, 3774 insertions(+), 3709 deletions(-)
   morgana% git diff -w --stat HEAD~1 | tail -1
    61 files changed, 894 insertions(+), 829 deletions(-)

However, after this step I hand-fixed some very ugly long expressions
(leaving them long: no content change at all is there).

If you find this patch with "git blame" please use "git blame -w"
to have all white-space ignored while associating lines to commits.

This commit has no practical effect but cleanup. I made it
with sed like this:

  git grep -l '[ \t]$' | xargs sed -i 's/[ \t]*$//'

However, I had to manually restore doc/wrpc_mon.png after the fact.
Similarly, I restored the include/hw/*regs.h files, as they
are (most likely) auto-generated.

As part of the fix, make the IP address private to the ipv4.c

Update Etherbone config space with correct IP address.

wrc_main starts bootp whenever link goes up
Rever Arria2 sys clock to 125MHz -- we had packet loss at 62.5MHz
Added IP training support to the shell
Have the shell reset the packet filter when the MAC is changed
