lib: utils: Implement "ranges" property parsing

2020-10-23T11:49:21Z

The "reg" property in a device node may not be the correct address always. If a parent node defines a "ranges" property, the child address need to be translated with respect to parents address. If the ranges property is not present, it will just use 1:1 translation. Signed-off-by: Atish Patra Reviewed-by: Anup Patel

lib: utils: Use strncmp in fdt_parse_hart_id()

2020-07-29T06:43:51Z

Use strncmp instead of using sbi_strcmp directly in fdt_parse_hart_id() to allow compiling fdt_helper.c by external firmware. Signed-off-by: Abner Chang Reviewed-by: Atish Patra Reviewed-by: Anup Patel

platform: Add support for Shakti C-class SoC from IIT-M

2020-06-19T03:51:46Z

C-Class is a member of the SHAKTI family of processors from Indian Institute of Technology - Madras(IIT-M). It is an extremely configurable and commercial-grade 5-stage in-order core supporting the standard RV64GCSUN ISA extensions. https://gitlab.com/shaktiproject/cores/c-class/blob/master/README.md We add OpenSBI support for Shakti C-class SoC.

lib: utils: Add fdt_parse_clint_node() function

2020-05-23T05:06:46Z

We add fdt_parse_clint_node() function which will be used by fdt_ipi_clint and fdt_timer_clint drivers to parse CLINT details from DT node. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: utils: Extend fdt_find_match() Implementation

2020-05-23T05:06:33Z

We extend fdt_find_match() implementation by adding node offset parameter which represents the first node to match from. The improved fdt_find_match() can be used to find multiple match nodes. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: utils: Allow PLIC functions to be used for multiple PLICs

2020-05-23T05:06:29Z

We extend all PLIC functions to have a "struct plic_data *" parameter pointing to PLIC details. This allows platforms to use these functions for multiple PLIC instances. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: utils: Add fdt_parse_plic_node() function

2020-05-01T04:15:53Z

We add fdt_parse_plic_node() function which will allow us to parse a particular DT node as PLIC node. This will be useful in parsing the DT node which we have found by matching compatible string. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: utils: Add fdt_parse_max_hart_id() API

2020-05-01T04:14:55Z

We add fdt_parse_max_hart_id() API which return max HART id based on CPU DT nodes. This will be used by generic FDT based drivers in subsequent patches. Signed-off-by: Anup Patel Reviewed-by: Atish Patra Reviewed-by: Alistair Francis

lib: utils: Add fdt_parse_hart_id() function

2020-05-01T04:13:07Z

Parsing HART id from a CPU DT node is a common requirement for RISC-V systems. The newly added fdt_parse_hart_id() also helps reduce duplicate code between fdt_cpu_fixup() function and fdt_parse_hart_count() function. Signed-off-by: Anup Patel Reviewed-by: Atish Patra Reviewed-by: Alistair Francis
