lib: utils/fdt: Use heap in FDT domain parsing

2023-06-05T10:29:35Z

Let's use heap allocation in FDT domain parsing instead of using a fixed size global array. Signed-off-by: Anup Patel Reviewed-by: Andrew Jones

lib: sbi: Fix how to check whether the domain contains fw_region

2023-04-06T10:44:35Z

Because firmware is split into rw/rx segments, it cannot be recorded by a root_fw_region. This problem is solved by adding a flag fw_region_inited to sbi_domain. Signed-off-by: Xiang W Reviewed-by: Himanshu Chauhan Reviewed-by: Anup Patel

lib: sbi: Add system_suspend_allowed domain property

2023-02-27T14:15:28Z

Only privileged domains should be allowed to suspend the entire system. Give the root domain this property by default and allow other domains to be given the property by specifying it in the DT. Signed-off-by: Andrew Jones Reviewed-by: Anup Patel

lib: utils/fdt/fdt_domain: Simplify region access permission check

2023-02-27T08:19:21Z

The region access permission check in __fdt_parse_region() can be simplified as masking SBI_DOMAIN_MEMREGION_{M,SU}_ACCESS_MASK is enough. While we are here, update the confusing comments to match the codes. Signed-off-by: Bin Meng Reviewed-by: Anup Patel

lib: utils: Disallow non-root domains from adding M-mode regions

2023-01-09T12:34:25Z

The M-mode regions can only be added to the root domain. The non-root domains shouldn't be able to add them from FDT. Signed-off-by: Himanshu Chauhan Reviewed-by: Anup Patel Tested-by: Anup Patel

lib: utils: Use SU-{R/W/X} flags for region permissions during parsing

2023-01-09T12:34:23Z

Use the newer SU-{R/W/X} flags for checking and assigning region permissions. Signed-off-by: Himanshu Chauhan Reviewed-by: Anup Patel Tested-by: Anup Patel

treewide: Replace TRUE/FALSE with true/false

2023-01-06T11:56:35Z

C language standard uses true/false for the boolean type. Let's switch to that for better language compatibility. Signed-off-by: Bin Meng Reviewed-by: Anup Patel Reviewed-by: Samuel Holland Tested-by: Samuel Holland

lib: fix __fdt_parse_region()

2022-12-09T05:56:39Z

If fdt_getprop() returns NULL, this indicates an error. In this case lenp is set to an error code. But even if lenp = 0 we should not continue. If fdt_getprop() returns a wider value than we expect this is a separate error condition. In both cases the device-tree is invalid.

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: Replace strcmp with strncmp

2021-05-19T12:05:38Z

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
