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

2022-05-14T04:46:50Z

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: utils/serial: support 'reg-offset' property

2022-04-17T08:27:48Z

reg-offset property is used for offset to apply to the mapbase from the start of the registers in 8250 UART. In Linux kernel, it has been handled in 8250 UART driver. dt-bindings: /Documentation/devicetree/bindings/serial/8250.yaml Signed-off-by: Zong Li Reviewed-by: Anup Patel

lib: utils: serial: Initial commit of xlnx-uartlite

2022-02-28T04:20:09Z

Initial commit of the xlnx-uartlite device and FDT support. This was tested by running OpenSBI on a modified QEMU virt machine using the xlnx-uartlite for serial. Signed-off-by: Alistair Francis Reviewed-by: Xiang W Reviewed-by: Anup Patel

lib: utils/irqchip: Add FDT based driver for APLIC

2022-02-15T15:09:01Z

We add simple FDT irqchip driver for APLIC so that generic platform (and other FDT based platforms) can utilize common APLIC initialization library. Signed-off-by: Anup Patel Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: utils/fdt: Add fdt_parse_timebase_frequency() function

2021-09-26T14:22:07Z

We add fdt_parse_timebase_frequency() function which can be used by ACLINT mtimer driver and platform code to get timebase frequency. Signed-off-by: Anup Patel Reviewed-by: Bin Meng Reviewed-by: Xiang W

lib: utils/fdt: Extend fdt_parse_aclint_node() function

2021-08-14T03:32:39Z

The fdt_parse_aclint_node() is used to parse DT node for SiFive CLINT, ACLINT MTIMER, and ACLINT MSWI devices. The ACLINT MTIMER has undergone following changes: 1) MTIMER DT node now requires separate addresses in for MTIME register and MTIMECMPx registers in the reg DT property. 2) MTIMER DT node might have no interrupts-extended DT property when the MTIMER device has no associated HARTs (i.e. the MTIMER device has no MTIMECMPx registers) This patch extends fdt_parse_aclint_node() to handle above mentioned changes in ACLINT MTIMER DT bindings.

lib: utils: Extend fdt_get_node_addr_size() for multiple register sets

2021-08-14T03:32:36Z

We add "index" parameter to fdt_get_node_addr_size() API so that calling function can specify index of desired register set. This will allow fdt_get_node_addr_size() to handle DT nodes with multiple register sets. Signed-off-by: Anup Patel Reviewed-by: Atish Patra
