platform: generic: Pass FDT to early/final_init overrides

2024-08-24T07:32:54Z

Several of these override functions access the FDT blob. Explicitly indicate which callbacks are allowed to modify the FDT blob by passing the parameter as a possibly-const pointer. This also reduces code size by deduplicating the call to fdt_get_address(). Signed-off-by: Samuel Holland Reviewed-by: Andrew Jones Reviewed-by: Anup Patel

platform: generic: Constify FDT pointers in fw_platform_init()

2024-08-24T07:32:51Z

Indicate that none of these functions modify the devicetree by constifying the parameter type. Signed-off-by: Samuel Holland Reviewed-by: Andrew Jones Reviewed-by: Anup Patel

lib: sbi: Allow ecall handlers to directly update register state

2023-12-19T10:26:37Z

Some of the upcoming SBI extensions (such as SSE) will directly update register state so improve the prototype of ecall handler to accommodate this. Further, this flexibility allows us to push the trap redirection from sbi_ecall_handler() to the sbi_ecall_legacy_handler(). Signed-off-by: Anup Patel

platform: generic: Introduce pmu_init() platform override

2023-12-06T12:19:59Z

Add pmu_init() platform override, which will be used to register PMU device and populate event mappings. Signed-off-by: Yu Chien Peter Lin Reviewed-by: Atish Patra Reviewed-by: Lad Prabhakar Reviewed-by: Anup Patel

platform: Allow platforms to specify the size of tlb fifo

2023-09-10T05:51:05Z

For some platforms with a particularly high number of harts, if the tlb fifo is too small, it case harts to wait. Platforms should be allowed to specify the size of the tlb fifo. Signed-off-by: Xiang W Signed-off-by: Xing Xiaoguang Reviewed-by: Anup Patel

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

platform: generic: Allow platform_override to perform firmware init

2023-01-07T10:28:54Z

We add a generic platform override callback to allow platform specific firmware init. Signed-off-by: Wei Liang Lim Reviewed-by: Chee Hong Ang Reviewed-by: Jun Liang Tan Reviewed-by: Anup Patel

platform: generic: Allow platform_override to select cold boot HART

platform: generic: add extensions_init handler and platform-override

2022-10-13T04:22:06Z

Init of non-standard extensions is a platform-specific thing, so allow generic platforms to do this via a platform-override. Reviewed-by: Andrew Jones Reviewed-by: Guo Ren Reviewed-by: Anup Patel Signed-off-by: Heiko Stuebner
