[PATCH 4/8] ARC: HAPS: add HIGHMEM memory zone to DTS
This is required as a preparation of merging nSIM and HASP
defonfig and device tree.
As we have HIGHMEM disabled in both HAPS and nSIM defconfigs
this doesn't lead to any functional change.

[PATCH 3/8] ARC: HAPS: use same UART configuration everywhere
For some reason we use ns8250 UART compatible on UP HAPS
configuration and ns16550a (which is ns8250 with FIFO support)
on SMP HAPS configuration.
Given that we have same UART IP with same IP configuration
on both HAPS configuration use ns16550a compatible everywhere.

[PATCH 5/8] ARC: HAPS: cleanup defconfigs from unused ETH drivers
We have multiple vendors ethernet drivers enabled in haps_hs and haps_hs_smp defconfig. The only one we possibly require is VIRTIO_NET. So disable unused ones via disabling entire CONFIG_ETHERNET which controls all vendor-specific ethernet drivers.

[PATCH 6/8] 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 minor changes which were done in previous commits.
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.
For nSIM we should now use UART property values
"-prop=nsim_mem-dev=uart0,kind=dwuart,base=0xf000"
instead of previously used
"-prop=nsim_mem-dev=uart0,base=0xc0fc1000"
"use_connect" and "irq" values of UART property remains untouched.
