dmaengine: dw: define DW_DMA_MAX_NR_MASTERS

2015-02-05T06:39:44+00:00

Instead of using magic number in the code the patch provides
DW_DMA_MAX_NR_MASTERS constant.

While here, restrict the reading of data width array by amount of the actual
number of AHB masters.

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

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

2014-10-13T09:16:15+00:00

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: [arcfpga] stdout-path now suffices for earlycon/console

2014-07-10T22:45:30+00:00

With recent improvements to serial/of core from Grant and Rob,
stdout-path alone suffices for setting up earlycon/console.

arc_uart driver is already equipped to handle that, switch the DT now.

ARC: [arcfpga] Early ARC UART to be only activated by cmdline

2014-06-03T08:50:09+00:00

Earlier CONFIG_SERIAL_ARC_CONSOLE would unconditionally enable the
legacy ARC UART based early console even if platform lacked that UART
(e.g. nSIM OSCI platform).

So a multi-platform image containing the 2 UART drivers won't work.

Fix that by probing the driver only if "earlyprintk=ttyARC0" is present
in cmdline.

ARC: [nsimosci] Unbork console

2014-04-05T13:06:51+00:00

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

2014-04-05T13:06:45+00:00

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.
