platform: generic: Modify platform ops instead of using hooks

2025-04-23T07:02:51Z

Switch all existing platform overrides to use the helper pattern instead of the platform hooks. After this commit, only the .match_table and .init members of struct platform_override are used. There are two minor behavioral differences: - For Allwinner D1, fdt_add_cpu_idle_states() is now called before the body of generic_final_init(). This should have no functional impact. - For StarFive JH7110, if the /chosen/starfive,boot-hart-id property is missing, the code now falls back to using generic_coldboot_harts, instead of accepting any hart.

platform: generic: andes: Remove inline definitions

2025-04-23T07:02:50Z

The addresses of these functions are used to set function pointers in struct platform_override, so it is not valid for them to be inline.

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: andes: Drop andes_pmu_setup()

2024-03-04T04:50:46Z

andes_pmu_setup() [1] was intended to populate event mapping from hardcoded arrays, however, this increases firmware size and we should just use PMU DT node [2] instead.
