dce crtc mem req and atombios

[Sylvain BERTRAND]

Hi,

On radeon hardware (I have an evergreen based board):

Must stopping/resuming the DCE to access the memory controller be done
with the EnableCRTCMemReq atombios table? (from DCE3 in dpm code).

Because, in evergreen.c, evergreen_mc_stop and evergreen_mc_resume
functions do not make use of that table (register direct access).

regards,

It doesn't matter.  They both do the same thing.
