platform: generic: Remove platform override hooks

2025-04-23T07:02:51Z

Now that all of the overrides are modifying generic_platform_ops directly, remove the unused hooks and forwarding functions. The remaining members of struct platform_override match struct fdt_driver, so use that type instead. This allows a future commit to reuse the fdt_driver-based init function.

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: 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

Like PMP, the behaviors to configure PMA will be different from RV64 and RV32. RV64 uses two Andes custom CSRs, pmacfg0 and pmacfg2, but RV32 uses four Andes custom CSRs, pmacfg0 ~ pmacfg3. This patch adds support to PMA for RV32. Signed-off-by: Ben Zong-You Xie Reviewed-by: Anup Patel
