lib: sbi_platform: expose hart_features to extension_init callback

2022-10-13T04:22:05Z

The platform-specific extension_init callback is supposed to set specific things for the platform opensbi is running on. So it's also the right place to override specific hart_features if needed - when it's know that autodetection has provided wrong results for example.

lib: sbi_platform: Add callback to populate HART extensions

2022-05-07T04:47:28Z

We add platform specific extensions_init() callback which allows platforms to populate HART extensions for each HART. For example, the generic platform can populate HART extensions from HART ISA string described in DeviceTree. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

include: Use static asserts for SBI_PLATFORM_xxx_OFFSET defines

Add static detection to prevent the modification of struct sbi_platform from forgetting the modification of SBI_PLATFORM_xxx_OFFSET Signed-off-by: Xiang W Reviewed-by: Anup Patel

include: sbi: Introduce nascent_init() platform callback

2022-02-15T15:04:24Z

We introduce nascent_init() platform callback which will allow platforms to do very early initialization of platform specific per-HART CSRs and per-HART devices. Signed-off-by: Anup Patel Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: sbi: Add PMU specific platform hooks

2021-07-11T04:51:38Z

A platform hook to initialize PMU allows platform vendors to provide their own mechanism to define pmu event-counter mappings in addition to the DT based approach. Another platform hook that allows platform vendors customize the final mhpmevent value configuration. Reviewed-by: Anup Patel Signed-off-by: Atish Patra

lib: sbi: Simplify HSM platform operations

2021-04-28T12:01:07Z

Instead of having hsm_start(), hsm_stop() and hsm_suspend() callbacks in platform operations, it will be much simpler for HSM driver to directly register these operations as a device to the sbi_hsm implementation. Signed-off-by: Anup Patel Reviewed-by: Alistair Francis

lib: sbi: Simplify system reset platform operations
