xtensa: clean up default platform functions

2023-06-13T02:48:56Z

Drop _F macro used to define default platform functions and rewrite definitions as normal functions. Don't define separate __platform_* function and platform_* weak alias, just define a weak function. Signed-off-by: Max Filippov

xtensa: drop platform_halt and platform_power_off

2023-06-13T02:48:56Z

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

2023-06-13T02:48:56Z

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

2023-06-13T02:48:55Z

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: drop empty platform_* functions from platforms

2020-01-31T20:17:28Z

Provide missing default implementation for platform_init and drop copies of default platform_init, platform_setup and platform_heartbeet from platforms/*/setup.c Signed-off-by: Max Filippov

xtensa: clean up platform headers

2020-01-31T20:17:25Z

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

xtensa: drop dead PCI support code

2019-06-17T06:31:28Z

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: cleanup ccount frequency tracking

2013-07-08T08:11:37Z

Remove unused nsec_per_ccount, and rename ccount_per_jiffy to ccount_preq. Signed-off-by: Baruch Siach Signed-off-by: Chris Zankel

xtensa: remove unused platform_init_irq()

2013-06-05T17:14:20Z

xtensa: provide default platform_pcibios_init implementation

2013-05-09T08:07:09Z

This fixes the following build error: arch/xtensa/kernel/built-in.o:(.init.literal+0xe8): undefined reference to `platform_pcibios_init' arch/xtensa/kernel/built-in.o: In function `setup_arch': (.init.text+0x20e): undefined reference to `platform_pcibios_init' and allows platform to omit definition of platform_pcibios_init if it's empty.
