xtensa: clean up platform headers

2020-01-31T20:17:25+00:00

Drop include directives for irrelevant headers in asm/platform.h and its users. Sort remaining headers. Signed-off-by: Max Filippov

xtensa: use the generic uncached segment support

2019-11-11T09:52:18+00:00

Switch xtensa over to use the generic uncached support, and thus the generic implementations of dma_alloc_* and dma_alloc_*, which also gains support for mmaping DMA memory. The non-working nommu DMA support has been disabled, but could be re-enabled easily if platforms that actually have an uncached segment show up.

xtensa: drop dead PCI support code

2019-06-17T06:31:28+00:00

xtensa-specific PCI initialization code has significantly bitrotted over time because there's no platform that use it. Get rid of remaining non-functioning initialization and remove platform_pcibios_* interface. A new platform that would use PCI on xtensa will configure PCI controller using device tree. Drop variables pci_ctrl_head, pci_bus_count and functions pcibios_init, pci_controller_apertures, platform_pcibios_init and platform_pcibios_fixup. Signed-off-by: Max Filippov

xtensa: platform-specific handling of coherent memory

2018-07-11T22:59:41+00:00

Memory layout is not fixed for noMMU xtensa configurations. Platforms that need to use coherent DMA should implement platform_vaddr_* helpers that check address type (cached/uncached) and convert addresses between these types. Signed-off-by: Max Filippov

xtensa: extract common CPU reset code into separate function

2016-09-12T06:53:22+00:00

platform_restart implementatations do the same thing to reset CPU. Don't duplicate that code, move it to a function and call it from platform_restart. Signed-off-by: Max Filippov

xtensa: remove unused platform_init_irq()

xtensa: clean up files to make them code-style compliant

2012-12-19T05:10:25+00:00

Remove heading and trailing spaces, trim trailing lines, and wrap lines that are longer than 80 characters. Signed-off-by: Chris Zankel

xtensa: remove platform rtc hooks

2009-04-03T06:45:07+00:00

platform_get/set_rtc_time() is not implemented by any of the supported xtensa platforms. Remove the facility completely. The initial seconds for xtime come from read_persistent_clock() which returns just 0 in the generic implementation. Platforms that sport a persistent clock can implement this function. This is needed to implement the ccount as a clock source. Signed-off-by: Johannes Weiner Signed-off-by: Chris Zankel

xtensa: move headers files to arch/xtensa/include

2008-11-06T18:25:09+00:00

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.
