xtensa: replace variant/core.h with asm/core.h

2019-05-07T00:48:55Z

Introduce the header arch/xtensa/include/asm/core.h that provides definitions for XCHAL macros missing in older xtensa releases. Use this header instead of variant/core.h Signed-off-by: Max Filippov

xtensa: drop variant IRQ support

2018-08-20T19:28:05Z

If an xtensa core provides an additional IRQ controller it should be treated as a separate piece of hardware and be driven by an irqchip driver. Signed-off-by: Max Filippov

xtensa: move PLATFORM_NR_IRQS to Kconfig

xtensa: don't use linux IRQ #0

2017-06-05T23:53:10Z

Linux IRQ #0 is reserved for error reporting and may not be used. Increase NR_IRQS for one additional slot and increase irq_domain_add_legacy parameter first_irq value to 1, so that linux IRQ #0 is not associated with hardware IRQ #0 in legacy IRQ domains. Introduce macro XTENSA_PIC_LINUX_IRQ for static translation of xtensa PIC hardware IRQ # to linux IRQ #. Use this macro in XTFPGA platform data definitions. This fixes inability to use hardware IRQ #0 in configurations that don't use device tree and allows for non-identity mapping between linux IRQ # and hardware IRQ #.

xtensa: add MX irqchip

2014-01-14T18:19:58Z

MX is an interrupt distributor used in some SMP-capable xtensa configurations. Signed-off-by: Max Filippov Signed-off-by: Chris Zankel

xtensa: move built-in PIC to drivers/irqchip

2014-01-14T18:19:56Z

Extract xtensa built-in interrupt controller implementation from xtensa/kernel/irq.c and move it to other irqchips, providing way to instantiate it from the device tree. Signed-off-by: Max Filippov Signed-off-by: Chris Zankel

xtensa: allow variant to initialize own irq chips

2009-06-22T09:36:59Z

There was already a PLATFORM_NR_IRQS define, which is now accompanied by a VARIANT_NR_IRQS. To be able to initialize these interrupts, init_IRQ now calls a variant specific hook. Changes compared to v1: - adapted to new CONFIG_VARIANT_IRQ_EXT - removed definition and call of platform_init_IRQ as there already is a platform_init_irq defined in asm/platform.h with a weak default in kernel/platform.c - renamed variant_init_IRQ to variant_init_irq Note that I could not find the call site of platform_init_irq although it is stated in platform.h that it is called from init_IRQ.

xtensa: variant irq set callbacks

2009-04-03T06:43:01Z

Allow the core variant code to provide irq enable/disable callbacks. Signed-off-by: Johannes Weiner Signed-off-by: Chris Zankel

xtensa: move headers files to arch/xtensa/include

2008-11-06T18:25:09Z

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.
