Expand description
The devictree header.
See https://devicetree-specification.readthedocs.io/en/v0.3/flattened-format.html#header
Fields§
§magic: U32<BigEndian>
The value 0xd00dfeed.
totalsize: U32<BigEndian>
The total size in bytes of the devicetree data structure.
This includes the header, the memory reservation block, structure block, as well as any gaps between or after the blocks.
off_dt_struct: U32<BigEndian>
The offset, in bytes, of the structure block.
off_dt_strings: U32<BigEndian>
The offset, in bytes, of the strings block.
off_mem_rsvmap: U32<BigEndian>
The offset, in bytes, of the memory reservation block.
version: U32<BigEndian>
The version of the devicetree structure.
last_comp_version: U32<BigEndian>
The lowest version of the devicetree data structure with which this version is backwards compatible.
boot_cpuid_phys: U32<BigEndian>
The physical ID of the system’s boot CPU.
size_dt_strings: U32<BigEndian>
The size, in bytes, of the strings block section.
size_dt_struct: U32<BigEndian>
The size, in bytes, of the structure block section.
