      ldscript and crt0.S: remove useless _gp · f235dfbc
      Alessandro Rubini authored
      The global pointer is used by some special assembly instructions
      that we are not using (i.e., the compiler is not generating them
      for us, because we don't use PIC or other "strange" stuff.
      
      So, we'd better remove an assignement in the linker script that makes
      little sense (it must be a typo of some kind, in the dark ages of this
      code base).

      softpll-unify: add new files, from wr-switch-sw/rt · 16bc0c8a
      Alessandro Rubini authored
      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.

      general: add copyright notes · 394d1405
      Alessandro Rubini authored
      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.

      arch/lm32/ram.ld: provide mprintf if missing · a502f9db
      Alessandro Rubini authored
      When we'll enable pp_printf, we'll need to resolve mprintf to
      it. Local files are fixed by #define in wrc.h, but ptp-noposix has
      explicit mprintf calls inside.  By using "PROVIDE" in the linker
      script, we resolve mprintf to pp_printf only if no native mprintf
      is part of the link stage. This has no effect if pp_printf is
      not selected.

      arch/lm32/ram.ld: remove all cruft · f05f3757
      Alessandro Rubini authored
      Remove all unneeded stuff from the linker script. Now the script only
      includes what is actually used: it is easier to understand and change
      (we'll add some local ELF sections), and it makes a better reference
      for possible porting to a different architecture.
      
      This commit also moves the default libraries from the linker script
      itself to the LDFLAGS in Makefile, where they really belong.
      
      CONFIG_DETERMINISTIC_BINARY confirms this makes no difference in
      the generated binary (nor the ELF FWIW).

      build: move libs from ldscript to LDFLAGS · 583ab278
      Alessandro Rubini authored
      Instead of picking libraries from the linker script, common practice
      is listing them in LDFLAGS. This simplifies review and modification.

      Run ./scripts/Lindent on all .c and .h files · e625cbd9
      Alessandro Rubini authored
      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).

      Remove all spaces at end-of-line · 1d24ecfb
      Alessandro Rubini authored
      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.
