11 | * How to use: | |
12 | * | |
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 | |
