Match data stores hardware attributes which do not change at runtime, so it does not need to be mutable. Make it const. Reviewed-by: Guo Ren Reviewed-by: Xiang W Reviewed-by: Anup Patel Signed-off-by: Samuel Holland

lib: utils/fdt: rename fdt_parse_max_hart_id

2022-05-14T04:48:12Z

The function returns the highest hart-id of the harts actually used in the system (enabled). Change the name to reflect this fact. Signed-off-by: Jan Remes Reviewed-by: Anup Patel

lib: utils/fdt: introduce fdt_node_is_enabled()

2022-05-14T04:46:24Z

If an FDT node contains a "status" property and this property is not "ok" or "okay", this node should be ignored. Introduce a function that checks this. Signed-off-by: Jan Remes Reviewed-by: Xiang W Reviewed-by: Anup Patel
