2018-01-18ARC: Enable fatal signals on boot for dev platformsAlexey Brodkin1-1/+1
It's very convenient to have fatal signals enabled on developemnt platform as this allows to catch problems that happen early in user-space (like crashing init or dynamic loader). Otherwise we may either enable it later from alive taregt console by "echo 1 > /proc/sys/kernel/print-fatal-signals" but: 1. We might be unfortunate enough to not reach working console 2. Forget to enable fatal signals and miss something interesting Given we're talking about development platforms here it shouldn't be a problem if a bit more data gets printed to debug console. Moreover this makes behavior of all our dev platforms predictable as today some platforms already have it enabled and some don't - which is way too inconvenient.

2016-11-01ARC: Enable PERF_EVENTS in nSIM driven platformsAlexey Brodkin1-0/+4
Now when we have properly working performance counters in nSIM even with interrupt support (fix should be a part of upcoming nSIM engineering build 2016.12-005) we may enable perf support by default for all platforms that use nSIM for ARC cores simulation. Note 1: PCT node was missing for some reason in nsimosci.dts while all other nSIM-related .dts files already had PCT node for quite some time, so adding it now. Note 2: All defconfigs were regenerated with "make savedefconfig" which led to some clean-ups in nsimosci_hs_smp_defconfig: CONFIG_FRAMEBUFFER_CONSOLE=y was removed because it is automatically selected now by DRM.

2016-10-01arc: Add "model" properly in device tree description of all boardsAlexey Brodkin1-0/+1
As it was discussed quite some time ago (see https://lkml.org/lkml/2015/11/5/862) it's a good practice to add "model" property in .dts. Moreover as per ePAPR "model" property is required and should look like "manufacturer,model" so we do here.

Linux 4.7-rc5 The fsl-dcu pull needs -rc3 so go to -rc5 for now.
2016-06-13ARC: [nsimosci] Enable ARC PGU on nSIM OSCI virtual platformsAlexey Brodkin1-3/+11
With required ARC PGU updates that allow it to be used on simulation platforms we may finally utilize ARC PGU in nSIM OSCI virtual platforms with modern Linux kernels. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2016-05-30arc: Get rid of root core-frequency propertyAlexey Brodkin1-1/+0
Now when we switched to usage of real clk devices for CPU core frequency those root properties make no sense any longer. Se we're just getting rid of them here to not confuse readers of our .dts files.

2016-05-09ARC: [dts] Add clk feeding into timers to DTsVineet Gupta1-0/+6
This allows us to introduce timers in DT in next commit The core clk frequency hack in AXS103 platform is also extended, where the core clk feeding into timers is updated in-place in FDT.

2016-03-15arc: [plat-nsimosci*] use ezchip network driverLada Trimasova1-3/+2
Since ezchip network driver was adapted to little endian architecture this patch provides the corresponding arch/arc/{boot/dts,configs}/ updates so we can switch over to this device-model/driver for OSCI platform.

2014-10-13ARC: [nsimosci] Allow "headless" models to bootVineet Gupta1-1/+1
There are certain test configuration of virtual platform which don't have any real console device (uart/pgu). So add tty0 as a fallback console device to allow system to boot and be accessible via telnet Otherwise with ttyS0 as only console, but 8250 disabled in kernel build, init chokes.

2014-04-05ARC: [nsimosci] Unbork consoleVineet Gupta1-1/+4
Despite the switch to right UART driver (prev patch), serial console still doesn't work due to missing CONFIG_SERIAL_OF_PLATFORM Also fix the default cmdline in DT to not refer to out-of-tree ARC framebuffer driver for console.

2014-04-05ARC: [nsimosci] Change .dts to use generic 8250 UARTMischa Jonker1-4/+3
The Synopsys APB DW UART has a couple of special features that are not in the System C model. In 3.8, the 8250_dw driver didn't really use these features, but from 3.9 onwards, the 8250_dw driver has become incompatible with our model.

2013-05-07ARC: Add support for nSIM OSCI System C modelMischa Jonker1-0/+77
This adds support for an ARC Virtual Platform. This platform is based on the System C standard promoted by the OSCI (Open System C Initiative) and uses nSIM to simulate the ARC CPU core itself. Users can build a virtual SoC by combining System C models of peripherals and CPU cores. Signed-off-by: Mischa Jonker <mjonker@synopsys.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
