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: check if CPU node is enabled

Ignore CPU nodes in FDT that are not enabled. 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

lib: sbi: Convert hart features into hart extensions

2022-05-07T04:46:30Z

Since past few years, we have been using "hart features" in OpenSBI to represent all optionalities and multi-letter extensions defined by the RISC-V specifications. The RISC-V profiles specification has taken a different approach and started assigning extension names for all optionalities which did not have any extension name previously. (Refer, https://github.com/riscv/riscv-profiles/blob/main/profiles.adoc) Inspired from the RISC-V profiles specification, we convert OpenSBI hart features into hart extensions. Going forward, we align the extension naming with RISC-V profiles specification. Currently, only "time CSR" and "AIA CSR" have not been assigned extension name but for everything else we have a name.
