This reads to stdout, in binary format. With "-v" it prints text and
scans the bus too. The examples here below use the same card (and same
data) as in commit "d44ace7e

 w1: complete eeprom low-level support".

Mainly, this removes the shell commands and the inclusion of <wrc.h>

This is the host part of the software-only uart. The lm32 part is
selected at compile time (CONFIG_UART_SW).

The tool, when run, opens one or more pty pairs, and reports to stdout
which is the name of the slave descriptor. You can then run
"minicom -p /dev/pts/XXX" or other commands, to access the software uart.

The tool builds all releases travelling back from the current one up
to the named one. For example:

  ./tools/git-compileall master

  [... all the compiles ...]

   Number of failed builds: 0
   The log of all compiles is at /tmp/makeall.out.67Rf3n
   The md5sums of wrc.o are at /tmp/mdlog.sZXrAi

The tool was born for internal use, so it is misnamed and so on. But
it may be useful to others too.

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.
