Macros
#define	RTEMS_MICROSECONDS_TO_TICKS(_us)    ( ( _us ) / rtems_configuration_get_microseconds_per_tick() )
	Gets the number of clock ticks for the microseconds value.
#define	RTEMS_MILLISECONDS_TO_MICROSECONDS(_ms)   ( ( _ms ) * 1000UL )
	Gets the number of microseconds for the milliseconds value.
#define	RTEMS_MILLISECONDS_TO_TICKS(_ms)    RTEMS_MICROSECONDS_TO_TICKS( RTEMS_MILLISECONDS_TO_MICROSECONDS( _ms ) )
	Gets the number of clock ticks for the milliseconds value.

Functions
bool	rtems_workspace_allocate (size_t bytes, void **pointer)
	Allocates a memory area from the RTEMS Workspace.
bool	rtems_workspace_free (void *pointer)
	Frees the memory area allocated from the RTEMS Workspace.
bool	rtems_workspace_get_information (Heap_Information_block *the_info)
	Gets information about the RTEMS Workspace.
void *	rtems_workspace_greedy_allocate (const uintptr_t *block_sizes, size_t block_count)
	Greedy allocates that empties the RTEMS Workspace.
void *	rtems_workspace_greedy_allocate_all_except_largest (uintptr_t *allocatable_size)
	Greedy allocates all blocks of the RTEMS Workspace except the largest free block.
void	rtems_workspace_greedy_free (void *opaque)
