From: Yuriy Kolerov <[email protected]>

This a series of patches for Synopsys ARC port that
have accumulated over the past years. It contains
several small fixes and a significant update of
libgloss for all supported boards for ARC targets:
IoT Development Kit, HS Development Kit, EM SDP
and EM Starter Kit.

Claudiu Zissulescu (3):
  arc: libgloss: Use long calls attribute for exit_halt
  arc: libc: Add support of 16-entry register file
  arc: libgloss: Use atexit to setup fini routines

Luis Silva (1):
  arc: libgloss: Use fstat call instead of stat for nSIM

Shahab Vahedi (1):
  arc: libc: Record r58/r59 in long-jump's buffer

Vladimir Isaev (1):
  arc: libgloss: Introduce hostlink interface

Yuriy Kolerov (9):
  arc: libc,libgloss: Remove .file directive from .S files
  arc: libgloss: Clean registers before any use
  arc: libgloss: Add UART 8250 library
  arc: libgloss: Add a linker script common for all boards
  arc: libgloss: Add support of IoT Development Kit board
  arc: libgloss: Add support of HS Development Kit board
  arc: libgloss: Add support of EM SDP board
  arc: libgloss: Add support of EM Starter Kit board
  arc: libgloss: Add build rules for new boards
