Patch from Eric Valette <valette@…> and Emmanuel Raguet
<raguet@…>:

  • the dec21140 driver code has been hardened (various bug fixed) Emmanuel,
  • bug in the mcp750 init code have been fixed (interrupt stack/initial stack initialization), BSS correctly cleared (Eric V)
  • remote debugging over TCP/IP is nearly complete (berakpoints, backtrace, variables,...) (Eric V),
  • exception handling code has also been improved in order to fully support RDBG requirements (Eric V),
  • Property mode set to 100644
