[U-Boot] Using __func__ and __LINE__ in debug outputs

[Graeme Russ]

Hi All,

What is the general consensus on using __func__ and __LINE__ in debug 
outputs?

My personal opinion is that distinct statements that can be grep'd are 
better for a couple of reasons:
  - It keeps the debug statements shorter
  - If your running a slightly older version of U-Boot, the line numbers 
(and possibly even the function names) may not match the current version 
of the source code

Regardless of whether we should use __func__ and __LINE__, greping for 
__func__ yields 1,837 hits with inconsistent usage. Should we not simply 
have a #define which tells debug() to output the function and line 
number in a consistent manner?

Regards,


Graeme
