* fsl-layerscape: Consolidate registers space defination for CCI-400 busAshish Kumar2017-09-111-0/+51
| | | | | | | | | | | | | | | | CoreLink Cache Coherent Interconnect (CCI) provides full cache coherency between two clusters of multi-core CPUs and I/O coherency for devices and I/O masters. This patch add new config option SYS_FSL_HAS_CCI400 and moves existing register space definaton of CCI-400 bus to fsl_immap to be shared. CONFIG_SYS_CCI400_ADDR is replaced with SYS_CCI400_OFFSET in Kconfig.
