ARC: [nsimosci] move peripherals to match model to FPGA

2015-04-09T12:13:39+00:00

commit e8ef060b37c2d3cc5fd0c0edbe4e42ec1cb9768b upstream.

This allows the sdplite/Zebu images to run on OSCI simulation platform

ARC: [nsimosci] Allow "headless" models to boot

2015-04-09T12:13:35+00:00

commit 5c05483e2db91890faa9a7be0a831701a3f442d6 upstream.

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.

ARC: [nsimosci] Unbork console

2014-04-18T09:07:21+00:00

commit 61fb4bfc010b0d2940f7fd87acbce6a0f03217cb upstream.

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.

ARC: [nsimosci] Change .dts to use generic 8250 UART

2014-04-18T09:07:20+00:00

commit 6eda477b3c54b8236868c8784e5e042ff14244f0 upstream.

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.

ARC: [TB10x] Remove redundant abilis,simple-pinctrl mechanism

2013-05-15T04:42:03+00:00

The TB10x platform port includes a custom mechanism using to set up
default pin controller configurations using abilis,simple-default
pin configurations of nodes compatible with abilis,simple-pinctrl. This
mechanism is redundant with the Linux standard "default" pin
configuration, see commit ab78029ecc347debbd737f06688d788bd9d60c1d
"drivers/pinctrl: grab default handles from device core".
This patch removes the TB10x custom mechanism in favour of the Linux
standard.
