ARC: [nsimosci] Unbork console

2014-04-14T13:42:19+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

2014-04-14T13:42:18+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.

ARC: Add support for nSIM OSCI System C model

2013-05-07T08:14:00+00:00

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.

ARC: [TB10x] Adapt device tree to new compatible string

2013-05-07T08:13:59+00:00

The original device tree was written using a slightly different
implementation of the fixed-factor-clock device tree binding. The
compatible string must be modified in order to be compatible with the
new implementation.

ARC: [TB10x] Device tree of TB100 and TB101 Development Kits

2013-05-07T08:13:58+00:00

These are the device tree files for the Abilis Systems TB100 and TB101 ICs and
their respective development kit PCBs. These files are committed in preparation
of the following patch set which adds support for these chips to the ARC
platform.

ARC: [kbuild] Avoid DTB rebuilds if DTS are untouched

2013-04-17T12:49:14+00:00

Currently, for every ARC kernel build I see the following:

--------------->8-----------------
  DTB    arch/arc/boot/dts/angel4.dtb.S
  AS      arch/arc/boot/dts/angel4.dtb.o
  LD      arch/arc/boot/dts/built-in.o
rm arch/arc/boot/dts/angel4.dtb.S        <-- forces rebuild next iter
  CHK     kernel/config_data.h
--------------->8-----------------

This is because *.dts.S is intermediate file in dtb generation and is by
default deleted by make which needs a ".SECONDARY" hint to NOT do so.

This could have ideally been done in scripts/Makefile.lib - for benefit
of all, however .SECONDARY doesn't seem to work with wildcards.

Thanks to Stephen for suggesting .SECONDARY (vs .PRECIOUS) and making
that work using a non wildcard version in arch makefile.

Thanks to James Hogan for pointing out that *.dtb.S now needs to be
added to clean-files

ARC: [build] Allow uncompressed uImage

2013-04-09T06:51:15+00:00

The existing uImage target always generates gzip compressed image which
drags bootup for some very slow FPGA customer boards.

So introduce seperate make targets:uImage.{bin,gz} with uncompressed
being default. Also tie gz generation to CONFIG_KERNEL_GZIP, which a
platform can select in it's Kconfig if it wishes gz to be default.
