|
* How to use:
|
||
|
|
*
|
||
|
|
* Before including this file, you need to
|
||
|
|
* #define __debug_variable my_debug
|
||
|
|
* where my_debug is a variable in your code which
|
||
|
|
* determines the debug bitmask.
|
||
|
|
*
|
||
|
|
* If CONFIG_HISAX_DEBUG is not set, all macros evaluate to nothing
|
