The Stretch s6000 family support has been merged into mainline 5 years
ago. There appear to be no users of this code since nobody complained
that there is a merge error preventing compilation.Apart from the s6105 IP camera reference design there are no s6000 devices
known to ever have run Linux and as the chips are out of production there
probably never will be. The successor s7000 no longer uses an Xtensa core
for the OS.Let's remove the code until someone is found who actually needs it.

Make sure that the 'static' keywork is at the beginning of declaration
for arch/xtensa/variants/s6000/include/variant/dmac.hThis 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).Signed-off-by: Jesper Juhl

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 requestedSigned-off-by: Daniel Glöckner

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.Signed-off-by: Oskar Schirmer

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.Signed-off-by: Johannes Weiner

Move all header files for xtensa to arch/xtensa/include and platform and
variant header files to the appropriate arch/xtensa/platforms/ and
arch/xtensa/variants/ directories.Moving the files gets also rid of all uses of symlinks in the Makefile.
This has been completed already for the majority of the architectures
and xtensa is one out of six missing.Signed-off-by: Sam Ravnborg
