Subject: [PATCH] ARC: Rename nSIM HS to HAPS HS
Date: Mon, 31 May 2021 13:12:10 -0700	[thread overview]
Message-ID: <20210531201210.32006-1-abrodkin@synopsys.com> (raw)

In v5.5 kernel we merged "nsim_hs" config into "haps_hs", see [1],
and from then on we use the same one "haps_hs" for everything simulated:
nSIM/QEMU/FPGA.

Of important notes:
 * We switched from legacy ARC UART to a standard DW UART

 * QEMU port for ARC is under review upstream, see [2].
   But even today with WIP version from our GitHub fork [3] its possible
   to run this image for "hapshs" machine as simple as:
   ----------------------------->8------------------------------
   $ qemu-system-arc -cpu archs -M virt -nographic -no-reboot -monitor none \
     -kernel build/tmp-glibc/deploy/images/hapshs/vmlinux-initramfs-hapshs.bin
   ----------------------------->8------------------------------
