5  * Implementation of linker-generated arrays
23  * llsym() - Access a linker-generated array entry
33  * ll_entry_declare() - Declare linker-generated array entry
39  * This macro declares a variable that is placed into a linker-generated
40  * array. This is a basic building block for more advanced use of linker-
44  * A variable declared using this macro must be compile-time initialized.
76  * ll_entry_declare_list() - Declare a list of link-generated array entries
99  * We need a 0-byte-size type for iterator symbols, and the compiler
103  * thing: zero-sized arrays, which are both 0-byte-size and exempt from
108  * ll_entry_start() - Point to first entry of linker-generated array
113  * linker-generated array placed into subsection of .u_boot_list section
133  * ll_entry_end() - Point after last entry of linker-generated array
139  * a linker-generated array placed into subsection of .u_boot_list
142  * Since this macro defines an array end symbol, its leftmost index
153 	static char end[0] __aligned(4) __attribute__((unused,		\
155 	(_type *)&end;							\
158  * ll_entry_count() - Return the number of elements in linker-generated array
162  * This function returns the number of elements of a linker-generated array
174  *           printf("Entry %i, x=%i y=%i\n", i, msc->x, msc->y);
179 		_type *end = ll_entry_end(_type, _list);		\
180 		unsigned int _ll_result = end - start;			\
185  * ll_entry_get() - Retrieve entry from linker-generated array by name
190  * This function returns a pointer to a particular entry in linker-generated
214  * ll_start() - Point to first entry of first linker-generated array
218  * the very first linker-generated array.
220  * Since this macro defines the start of the linker-generated arrays,
237  * ll_end() - Point after last entry of last linker-generated array
241  * the very last linker-generated array.
243  * Since this macro defines the end of the linker-generated arrays,
