| 1da177e4 LT |
13 | * Before including this file, you need to |
| 14 | * #define __debug_variable my_debug | |
| 15 | * where my_debug is a variable in your code which | |
| 16 | * determines the debug bitmask. | |
| 17 | * | |
| 18 | * If CONFIG_HISAX_DEBUG is not set, all macros evaluate to nothing | |
