[PATCH] ARC: rework setting of ARC CPU specific compiler options

2020-02-12 Thread Eugeniy Paltsev
It's a very rare if at all existing occasion when ARC CPU template is used as is w/o any changes - in the end it's a beauty and competitive advantage of ARC cores to be tailored for a particular use-case - and so it doesn't make a lot of sense to offer template-based "-mcpu" selection. Given for ea

[PATCH 3/3 v2] ARC: nsim_hs38: Add support of Virtio NET & BLK

2020-02-12 Thread Alexey Brodkin
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 --- Changes v1 -> v2: * Instead of adding IRQ parent it might be mu

[PATCH 1/3 v2] ARC: nSIM: switch from ARC UART to DW UART

2020-02-12 Thread Alexey Brodkin
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

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 --- No changes v1 -> v2. configs/nsim_700_defconfig| 1 +
