lib: sbi: Improve system reset platform operations

2020-12-01T11:40:31Z

To implement the SBI SRST extension, we need two platform operations for system reset: 1) system_reset_check() - This operation will check whether given reset type and reason are supported by the platform 2) system_reset() - This operation will do the actual platform system reset and it will not return if reset type and reason are supported by the platform This patch updates system reset related code everywhere as-per above.

include: sbi: Remove opensbi specific reset type defines

2020-12-01T11:35:12Z

We can now use the standard SBI SRST extension reset types instead of the opensbi specific (SBI_PLATFORM_RESET_xyz) reset types hence remove related opensbi specific defines. The "platform_" prefix of the reset type parameter of sbi_system_reset() function should also be removed. Signed-off-by: Anup Patel Reviewed-by: Alistair Francis Reviewed-by: Atish Patra

include: sbi_platform: Combine reboot and shutdown into one callback

2020-04-27T09:05:29Z

We can achieve shutdown, cold reboot, and warm reboot using just one sbi_platform callback so we combine system_reboot() and system_shutdown() callbacks into one system_reset() callback. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: improve system reboot and shutdown implementation

2020-01-07T06:41:36Z

We improve sbi_system_reboot() an sbi_system_shutdown() by: 1. Calling halt IPI to all harts (except current HART) before calling platform reboot/shutdown hook. 2. Calling sbi_exit() instead of sbi_hang() in-case platform reboot/shutdown hook failed. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: Add system early_exit and final_exit APIs

2020-01-07T06:40:48Z

This patch adds system-level early_exit and final_exit APIs with corresponding platform hooks. These new APIs will be primarily used by sbi_exit() in OpenSBI exit path. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: Remove hartid paramter from early_init() and final_init() callbacks

We simplify early_init() and final_init() callbacks of sbi_platform by removing "hartid" parameter. Signed-off-by: Anup Patel

lib: Simplify sbi_platform early_init() and final_init() hooks

2018-12-27T04:05:09Z

Instead of having separate early_init() and final_init() hooks for cold and warm boot, this patch updates struct sbi_platform to have just one early_init() and one final_init() hook. The type of boot (cold or warm) is now a boolean flag parameter for the updated early_init() and final_init() hooks. Signed-off-by: Anup Patel
