Functions
rtems_status_code	rtems_bdpart_read (const char disk_name, rtems_bdpart_format format, rtems_bdpart_partition partitions, size_t count)
	Reads the partition information from the physical disk device with name disk_name.

void	rtems_bdpart_sort (rtems_bdpart_partition *partitions, size_t count)
	Sorts the partition table partitions with count partitions to have ascending begin blocks.

rtems_status_code	rtems_bdpart_write (const char disk_name, const rtems_bdpart_format format, const rtems_bdpart_partition *partitions, size_t count)
	Writes the partition table to the physical disk device with name disk_name.

rtems_status_code	rtems_bdpart_create (const char disk_name, const rtems_bdpart_format format, rtems_bdpart_partition partitions, const unsigned distribution, size_t count)
	Creates a partition table in partitions with count partitions for the physical disk device with name disk_name.

rtems_status_code	rtems_bdpart_register (const char disk_name, const rtems_bdpart_partition partitions, size_t count)
	Registers the partitions as logical disks for the physical disk device with name disk_name.

rtems_status_code	rtems_bdpart_register_from_disk (const char *disk_name)

rtems_status_code	rtems_bdpart_unregister (const char disk_name, const rtems_bdpart_partition partitions, size_t count)
	Deletes the logical disks associated with the partitions of the disk device with name disk_name.

void	rtems_bdpart_dump (const rtems_bdpart_partition *partitions, size_t count)
	Prints the partition table partitions with count partitions to standard output.

void	rtems_bdpart_to_partition_type (uint8_t mbr_type, uuid_t type)
	Returns the partition type for the MBR partition type value mbr_type in type.

bool	rtems_bdpart_to_mbr_partition_type (const uuid_t type, uint8_t *mbr_type)
	Converts the partition type in type to the MBR partition type.

rtems_status_code	rtems_bdpart_get_disk_data (const char disk_name, int fd_ptr, rtems_disk_device *dd_ptr, rtems_blkdev_bnum disk_end)
