xtensa: drop platform_halt and platform_power_off

2023-06-13T02:48:56+00:00

Instead of using xtensa-specific platform_halt and platform_power_off callbacks use do_kernel_power_off in the machine_halt and machine_power_off and reimplement existing platform_halt and platform_power_off users with register_sys_off_handler. Drop platform_halt and platform_power_off declarations and default implementations. Signed-off-by: Max Filippov

xtensa: drop platform_restart

2023-06-13T02:48:56+00:00

Instead of using xtensa-specific platform_restart callback use do_kernel_restart in the machine_restart implementation and reimplement existing platform_restart users with register_restart_handler. Drop platform_restart declaration and default implementation. Signed-off-by: Max Filippov

xtensa: drop platform_heartbeat

2023-06-13T02:48:55+00:00

platform_heartbeat is called from the timer interrupt handler, but there may be no periodic timer interrupts on xtensa, so the frequency of platform_heartbeat calls may be unrelated to HZ. Drop the callback and reimplement its only user with a timer. Signed-off-by: Max Filippov

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
