LINK_HARD_RESET. Link Hard Reset
Re-initialize resetting values in sticky registers. Write 1 to reset this link. This is 
a destructive reset. When reset asserts, register clears to 0h.

LINK_SOFT_RESET. Link Soft Reset 
Re-initialize without resetting sticky registers. Write 1 to reset this link. This is a 
destructive reset. When reset asserts, register clears to 0h.

CHANNEL1_ACTIVE
When set, indicates MC channel 1 is active. This bit is controlled (set/reset) 
by software only. This bit is required to be set for any active channel when 
INIT_DONE is set by software.

CHANNEL0_ACTIVE
When set, indicate MC channel 0 is active. This bit is controlled (set/reset) 
by software only. This bit is required to be set for any active channel when 
INIT_DONE is set by software.

INIT_DONE
MC initialize complete signal. Setting this bit will exit the training mode of 
the Integrated Memory Controller and begin normal operation including all 
enabled maintenance operations. Any CHANNNEL_ACTIVE bits not set 
when writing a 1 to INIT_DONE will cause the corresponding channel to be 
disabled.
