XTENSA: static should be at beginning of declaration

2011-07-11T12:13:47+00:00

Make sure that the 'static' keywork is at the beginning of declaration
for arch/xtensa/variants/s6000/include/variant/dmac.h

This gets rid of warnings like
  warning: ‘static’ is not at beginning of declaration
when building with -Wold-style-declaration (and/or -Wextra which also
enables it).

xtensa: support s6000 gpio irqs and alternate function selection

2009-06-22T09:37:26+00:00

Implement an irq chip to handle interrupts via gpio.  The GPIO chip
initialization function now takes a bitmask denoting pins that should
be configured for their alternate function.

changes compared to v1:
- fixed bug on edge interrupt configuration
- accommodated to function name change
- moved definition of VARIANT_NR_IRQS to this patch
- renamed __XTENSA_S6000_IRQ_H to _XTENSA_S6000_IRQ_H as requested

xtensa: s6000 dma engine support

2009-06-22T09:37:11+00:00

There are four slightly different dma engines on the s6000 family.
One for memory-memory transfers, the other three for memory-device.

This patch implements a platform-specific kernel-API to control these
engines.  It is needed for the network, video, audio peripherals on
s6000.

xtensa: implement ccount calibration for s6000

2009-05-12T05:00:17+00:00

Calculate core frequency from timers at boot time
instead of assuming a fixed frequency. This is
useful as the true frequency is set up by the
boot loader, thus variable.

xtensa: register gpio chip before use

2009-05-12T05:00:07+00:00

Platform initialization sets up the LED heartbeat that is controlled
via GPIO.  Requesting the GPIO pins fails, however, as the chip is
only initialized later by a device_initcall().

Fix this up by exporting the initialization function.  Let the
platform set up the chip before it starts using it.

xtensa: only build platform or variant if they contain a Makefile

2009-04-03T07:06:45+00:00

We only add the platform or variant directory to core-y if it
contains a Makefile. Consequently, we can remove the Makefiles
for the dc232b and fsf processor variants.
