| 51 | * Some of the platform porting definitions use the 'ull' suffix in order to |
| 52 | * avoid subtle integer overflow errors due to implicit integer type promotion |
| 53 | * when working with 32-bit values. |
| 54 | * |
| 55 | * The TSP linker script includes some of these definitions to define the BL3-2 |
| 56 | * memory map, but the GNU LD does not support the 'ull' suffix, causing the |
| 57 | * build process to fail. To solve this problem, the auxiliary macro MAKE_ULL(x) |
| 58 | * will add the 'ull' suffix only when the macro __LINKER__ is not defined |
| 59 | * (__LINKER__ is defined in the command line to preprocess the linker script). |
| 60 | * Constants in the linker script will not have the 'ull' suffix, but this is |
| 61 | * not a problem since the linker evaluates all constant expressions to 64 bit |
| 62 | * (assuming the target architecture is 64 bit). |
