platform: Allow platforms to specify heap size

2023-06-05T10:15:33Z

We extend struct sbi_platform and struct sbi_scratch to allow platforms specify the heap size to the OpenSBI firmwares. The OpenSBI firmwares will use this information to determine the location of heap and provide heap base address in per-HART scratch space. Signed-off-by: Anup Patel Reviewed-by: Andrew Jones

include: sbi: Remove extid parameter from vendor_ext_provider() callback

2023-02-27T05:56:37Z

The extid parameter of vendor_ext_provider() is redundant so let us remove it. Signed-off-by: Anup Patel

lib: sbi: Align SBI vendor extension id with mvendorid CSR

2023-02-27T05:56:35Z

As-per the SBI specification, the lower 24bits of the SBI vendor extension id is same as lower 24bits of the mvendorid CSR. We update the SBI vendor extension id checking based on above. Signed-off-by: Anup Patel

lib: sbi: Allow platform to influence cold boot HART selection

2023-01-07T10:28:49Z

We add an optional cold_boot_allowed() platform callback which allows platform support to decide which HARTs can do cold boot initialization. If this platform callback is not available then any HART can do cold boot initialization. Signed-off-by: Anup Patel

treewide: Replace TRUE/FALSE with true/false

2023-01-06T11:56:35Z

C language standard uses true/false for the boolean type. Let's switch to that for better language compatibility. Signed-off-by: Bin Meng Reviewed-by: Anup Patel Reviewed-by: Samuel Holland Tested-by: Samuel Holland

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

2022-03-27T03:37:44Z

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
