Detailed Description

Class encapsulating the entire parsed FDT. This is the top-level class, which parses the entire DTS representation and write out the finished version.

Member Typedef Documentation

typedef std::vector<std::pair<string,string> > dtc::fdt::device_tree::node_path

Type used for node paths. A node path is sequence of names and unit addresses.

Member Enumeration Documentation

enum dtc::fdt::device_tree::phandle_format

Name that we should use for phandle nodes.

Enumerator:

LINUX	linux,phandle
EPAPR	phandle
BOTH	Create both nodes.

Constructor & Destructor Documentation

dtc::fdt::device_tree::device_tree ( )

inline

Default constructor. Creates a valid, but empty FDT.

dtc::fdt::device_tree::~device_tree ( )

inline

Destroy the tree and any input buffers that it holds.

Member Function Documentation

void dtc::fdt::device_tree::add_include_path ( const char *  path )

inline

Adds a path to search for include files. The argument must be a nul-terminated string representing the path. The device tree keeps a pointer to this string, but does not own it: the caller is responsible for freeing it if required.

node* dtc::fdt::device_tree::get_root ( ) const

inline

Returns a pointer to the root node of this tree. No ownership transfer.

bool dtc::fdt::device_tree::is_valid ( )

inline

Returns whether this tree is valid.

void dtc::fdt::device_tree::parse_dtb ( const char *  fn, FILE *  depfile  )

inline

Constructs a device tree from the specified file name, referring to a file that contains a device tree blob.

void dtc::fdt::device_tree::parse_dts ( const char *  fn, FILE *  depfile  )

inline

Constructs a device tree from the specified file name, referring to a file that contains device tree source.

node* dtc::fdt::device_tree::referenced_node ( property_value &  v )

inline

Returns the node referenced by the property. If this is a tree that is in source form, then we have a string that we can use to index the cross_references array and so we can just look that up.

void dtc::fdt::device_tree::set_blob_minimum_size ( uint32_t  s )

inline

Sets the minimum size, in bytes, of the blob.

void dtc::fdt::device_tree::set_blob_padding ( uint32_t  p )

inline

Sets the amount of padding to add to the blob.

void dtc::fdt::device_tree::set_boot_cpu ( uint32_t  cpu )

inline

Sets the physical boot CPU.

void dtc::fdt::device_tree::set_empty_reserve_map_entries ( uint32_t  e )

inline

Sets the number of empty reserve map entries to add.

void dtc::fdt::device_tree::set_phandle_format ( phandle_format  f )

inline

Sets the format for writing phandle properties.

void dtc::fdt::device_tree::sort ( )

inline

Sorts the tree. Useful for debugging device trees.

void dtc::fdt::device_tree::write_asm ( int  fd )

inline

Writes this FDT as an assembly representation of the DTB to the specified output. The result can then be assembled and linked into a program.

void dtc::fdt::device_tree::write_binary ( int  fd )

inline

Writes this FDT as a DTB to the specified output.

void dtc::fdt::device_tree::write_dts ( int  fd )

inline

Writes the tree in DTS (source) format.
