Detailed Description

Class encapsulating the device tree blob header. This class stores all of the values found in the header and is responsible for writing them to the output.

Constructor & Destructor Documentation

dtc::dtb::header::header ( )

inline

Default constructor. Initialises the values that have sensible defaults, leaves the others blank.

Member Function Documentation

bool dtc::dtb::header::read_dtb ( input_buffer &  input )

inline

Reads the header from bits binary representation in a blob.

void dtc::dtb::header::write ( output_writer &  out )

inline

Writes the entire header to the specified output buffer.

Member Data Documentation

uint32_t dtc::dtb::header::boot_cpuid_phys

The ID of the CPU where this boots.

uint32_t dtc::dtb::header::last_comp_version

The earliest version of the DTB specification with which this blob is backwards compatible. This should always be 16.

uint32_t dtc::dtb::header::magic

Magic value, used to validate that this really is a device tree blob. Should always be set to 0xd00dfeed.

uint32_t dtc::dtb::header::off_dt_strings

The offset from the start of the blob of the strings table.

uint32_t dtc::dtb::header::off_dt_struct

The offset from the start of the blob of the struct table (i.e. the part of the blob containing the entire device tree).

uint32_t dtc::dtb::header::off_mem_rsvmap

The offset of the reservation map from the start of the blob.

uint32_t dtc::dtb::header::size_dt_strings

The size of the strings table.

uint32_t dtc::dtb::header::size_dt_struct

The size of the struct table.

uint32_t dtc::dtb::header::totalsize

The total size of the blob, including header, reservations, strings table, and padding.

uint32_t dtc::dtb::header::version

The version of the blob. This should always be 17.
