PA_SC_RASTER_CONFIG

[Sylvain BERTRAND <sylware@legeek.net>]

Hi,

----

In si.c, the PA_SC_RASTER_CONFIG register is set with a
golden value in 'si_init_golden_registers' function but get
set nearly immediately after in 'si_setup_rb' function at a finer
level (for each sh block of each se block).
If I remember well, that golden value would be again set to the
golden value in mesa.

Is there one golden value for all se/sh blocks? Or are there computed
(then overwritting the golden value) values for each se/sh? Why
mesa would overwrite its value (I have not checked in lastest
mesa)?

In drm-next-3.10 branch, commit
c9e065819056dd00ccecbf17a73ade03fa03ca8e, in
verde_golden_registers, many registers are set several times
in a row, expected? (that does not look like sequential
programing registers, maybe some register backbone block routing
trickery?)
