lib: utils/fdt: Fix DT property for APLIC delegation

2024-06-05T05:24:59Z

During Linux AIA driver review, the APLIC DT property for interrupt delegation was renamed to "riscv,delegation" so let's use the new DT property name and fallback to old DT property name if the new DT property name is not available.

lib: utils: check correct value in fdt_node_offset_by_compatible

2024-04-10T04:08:26Z

After calling fdt_node_offset_by_compatible() we must check its return value and not an unrelated value.

platform: generic: Add support for specify coldboot harts in DT

2024-02-20T10:19:36Z

Added support for the generic platform to specify the set of coldboot hart in DT. If not specified in DT, all harts are allowed to coldboot as before. The functions related to sbi_hartmask are not available before coldboot, so I used bitmap, and added a new bitmap_test() function to test whether a certain bit of the bitmap is set.

lib: utils/timer: mtimer: only use regname for aclint

2023-12-27T06:27:33Z

The parser will fail if the timer is clint timer and has regname property. As the regname is only meaningful for aclint, it is more robust to only check regname for aclint timer.

lib: utils/irqchip: Add shared MMIO region for PLIC in root domain

2023-12-19T10:26:37Z

On platforms with Smepmp, the MMIO regions accessed by M-mode need to be explicitly marked with M-mode only read/write or shared (both (M-mode and S-mode) read/write permission. If the above is not done then runtime PLIC access from M-mode on platforms with Smepmp will result in access fault when further results in CPU hotplug not working. Signed-off-by: Anup Patel

lib: utils/fdt: Allow to use reg-names when parsing ACLINT

2023-12-11T05:05:32Z

Currently, the fdt_parse_aclint_node() follows a fixed order to parse ACLINT timer. This may cause the undesirable result when the ACLINT device does not support mtime without adding an empty entry for it in the DT. To be robust, make fdt_parse_aclint_node() support "reg-names" property, so it can parse the DT in an order independent way. For compatibility, fdt_parse_aclint_node() only use "reg-names" when parsing ACLINT timer, and will fallback to the old way if "reg-names" property is not found.

2023-12-06T12:45:41Z

To allow platform override pmu_init() filling the translation table fdt_pmu_evt_select[] when PMU node doesn't provide such information, we need to share the table and its entry counter with other .c file. We also define the structures of PMU property in fdt_helper.h, so we can initialize the mappings in arrays. Signed-off-by: Yu Chien Peter Lin Reviewed-by: Atish Patra Reviewed-by: Anup Patel
