[PATCH 1/3] ARC: nSIM: switch from ARC UART to DW UART

Since v2019.06 DesingWare nSIM supports DesignWare UART simulation and so we may switch from pretty unusual ARC UART to much more standard DesignWare UART (which in case of U-Boot is just an ordinary 16650 UART). This among other things makes built dinaries compatible with our other platforms to n

[PATCH 2/3] ARC: nsim_{700|700be|hs38be}_defconfigs: Disable networking

We don't have yet any brc700 or big-enadian platforms with networking support to run this particular configuration. Whenever QEMU for ARC supports arc700 or big-endian targets we may revisit this one. Signed-off-by: Alexey Brodkin --- configs/nsim_700_defconfig| 1 + configs/nsim_700be_defc

[PATCH 0/3] ARC nSIM (AKA virtual & prototyping platform) updates

In this small series we refubrish olde good nSIM configs & platform so that it no uses standard 16650 (in fact DesignWare) UART and little-endian HS version also gets Virtio support (Net & BLK) for use with QEMU. Alexey Brodkin (3): ARC: nSIM: switch from ARC UART to DW UART ARC: nsim_{700|700

[PATCH 3/3] ARC: nsim_hs38: Add support of Virtio NET & BLK

Given now nsim_hs38 configuration is usable on QEMU and in QEMU we have Virtio working perfectly fine the next logical step is to add support of supported & known to work net & bkl to this config. Signed-off-by: Alexey Brodkin --- arch/arc/Kconfig | 4 ++-- arch/arc/dts/nsim.dt
