[U-Boot] [PATCH v3 5/5] ARM: ls102xa: Setting device's stream id for SMMUs.

Xiubo Li Li.Xiubo at freescale.com
Mon Oct 20 11:00:50 CEST 2014 

LS1 has 4 SMMUs for address translation of the masters. All the
SMMUs' stream IDs are 8-bit. The address translation depends on the
stream ID of the incoming transaction.
Each master has unique stream ID assigned to it and is configurable
through SCFG registers. The stream ID for the masters is identical
and share the same register field of STREAM ID registers.
