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: xt2000: drop empty platform_init

2023-06-13T02:48:55Z

platform_init doesn't do anything for xt2000, drop it. Signed-off-by: Max Filippov

xtensa: no need to initialise statics to 0

2022-05-11T09:15:35Z

Static variables do not need to be initialised to 0, because compiler will initialise all uninitialised statics to 0. Thus, remove the unneeded initializations. Signed-off-by: Jason Wang Message-Id: <20220508022910.98481-1-wangborong@cdjrlc.com> Signed-off-by: Max Filippov

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: rework {CONFIG,PLATFORM}_DEFAULT_MEM_START

2018-08-20T19:28:03Z

Drop PLATFORM_DEFAULT_MEM_START from the platform/hardware.h headers. Provide definition of CONFIG_DEFAULT_MEM_START always, allow changing it only in noMMU configurations when PLATFORM_WANT_DEFAULT_MEM is selected. Change prompt and description so that it's clear that it controls PAGE_OFFSET and PHYS_OFFSET. Signed-off-by: Max Filippov
