Subject: [PATCH 0/8] ARC: merge HAPS-HS with nSIM-HS configs

Starting from nSIM 2019.06 is possible to use DW UART
instead of ARC UART. That allows us to merge
"nsim_hs" with "haps_hs" and "nsim_hs_smp" with "haps_hs_smp"
with some minor changes.

We eliminate nsim_hs_defconfig and nsim_hs_smp_defconfig
and leave haps_hs_defconfig and haps_hs_smp_defconfig
which can be used on HAPS / nSIM / ZEBU / QEMU platforms
without additional changes in Linux kernel.

Also while I'm at it cleanup both HAPS and nSIM configurations
from obsolete/unused options.

Changes:
RFC -> v1:
 * update KBUILD_DEFCONFIG to use the haps defconfig instead of
   nSIM one
 * switch nsim_700 to dwuart

Eugeniy Paltsev (8):
  ARC: regenerate nSIM and HAPS defconfigs
  ARC: HAPS: cleanup defconfigs from unused IO-related options
  ARC: HAPS: use same UART configuration everywhere
  ARC: HAPS: add HIGHMEM memory zone to DTS
  ARC: HAPS: cleanup defconfigs from unused ETH drivers
  ARC: merge HAPS-HS with nSIM-HS configs
  ARC: nSIM_700: switch to DW UART usage
  ARC: nSIM_700: remove unused network options
