lib: utils/fdt: Add fdt_parse_phandle_with_args() API

2021-07-17T06:10:49+00:00

The libfdt project does not have a generic API to parse phandle with args from a DT node so we add fdt_parse_phandle_with_args() for this purpose. This new API will be useful to FDT based drivers. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

utils: fdt: Add fdt helper functions to parse PMU DT nodes

2021-07-11T04:57:57+00:00

The PMU DT node bindings are defined in docs/pmu_support.md Add few fdt helper functions to parse the DT node and update the event-counter mapping tables. Reviewed-by: Anup Patel Signed-off-by: Atish Patra

lib: utils: Add FDT parsing API common for both ACLINT and CLINT

2021-06-24T04:09:48+00:00

We add fdt_parse_aclint_node() which can parse both ACLINT and CLINT DT nodes. This means fdt_parse_clint_node() is not required anymore so we remove it as well. Signed-off-by: Anup Patel Reviewed-by: Bin Meng Reviewed-by: Xiang W

lib: utils/fdt: Replace strcmp with strncmp

2021-05-19T12:05:38+00:00

Use strncmp() instead of strcmp() in __fixup_find_domain_offset() so that it compiles fine when linking with external firmware (such as EDK2). Signed-off-by: Daniel Schaefer Reviewed-by: Xiang W Reviewed-by: Abner Chang Reviewed-by: Anup Patel

lib: utils/fdt: Don't use sbi_string functions

2021-05-19T12:04:06+00:00

When SBI is built by external firmware, we need to use their functions, defined in libfdt_env.h. Just like 2cfd2fc9048806353298a1b967abf985901e36e8 Signed-off-by: Daniel Schaefer Reviewed-by: Abner Chang Reviewed-by: Xiang W Reviewed-by: Anup Patel

lib: utils/serial: Add support for Gaisler APBUART

2021-05-06T08:51:07+00:00

This patch adds support for the UART used by the NOEL-V processor. Cobham Gaisler's NOEL-V RISC-V processor IP is available under GPL and commercial license and is described in more detail at https://www.gaisler.com/noelv.

lib: utils: Implement "64bit-mmio" property parsing

2021-04-22T09:30:58+00:00

Figure out CLINT has_64bit_mmio from DT node and using antonym for compatibility. Signed-off-by: Guo Ren Reviewed-by: Anup Patel

lib: utils: Copy over restricted root domain memregions to FDT domains

2021-04-13T05:26:48+00:00

We should copy over all restricted memregions from the root domain to the domains populated from FDT. These restricted root memregions are typically firmware memregion and M-mode only mmio memregions. Signed-off-by: Anup Patel Reviewed-by: Xiang W Reviewed-by: Alistair Francis

lib/utils: Support fixing up the official DT bindings of PLIC

2021-04-01T05:01:11+00:00

Current fdt_plic_fixup() only does necessary fix-up against the legacy "riscv,plic0" node. The upstream Linux kernel defines its official DT bindings which uses "sifive,plic-1.0.0" as the compatible string and we should check that first, and if not present fall back to legacy.

lib/utils: Drop the 'compat' parameter of fdt_plic_fixup()

2021-04-01T04:57:28+00:00

At present fdt_plic_fixup() accepts a 'compat' parameter for PLIC compatible string. In preparation to support the new DT bindings, drop this and use "riscv,plic0" directly in fdt_plic_fixup(). Signed-off-by: Bin Meng Reviewed-by: Anup Patel
