CoreLink Cache Coherent Interconnect (CCI) is ARM BUS which 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 defination "SYS_FSL_HAS_CCI400" and moves existing register space definaton of CCI-400 bus from immap_lsch2 to fsl_immap, so that it can be used for both chasis 2 and chasis 3. "CONFIG_SYS_CCI400_ADDR" is depricated and new SYS_CCI400_OFFSET is introduced in Kconfig Signed-off-by: Ashish Kumar <ashish.ku...@nxp.com> Signed-off-by: Prabhakar Kushwaha <prabhakar.kushw...@nxp.com> --- v3: This is v3 for https://patchwork.ozlabs.org/patch/731464/ v4: Header file included in middle of the file in cpu.c v5: Moving ls1021aqds to 2/3-armv7 of this patch-set README | 9 ++++ arch/arm/cpu/armv8/fsl-layerscape/Kconfig | 13 ++++++ arch/arm/cpu/armv8/fsl-layerscape/cpu.c | 1 + arch/arm/cpu/armv8/fsl-layerscape/soc.c | 10 +++-- .../include/asm/arch-fsl-layerscape/immap_lsch2.h | 49 --------------------- board/freescale/ls1012afrdm/ls1012afrdm.c | 4 +- board/freescale/ls1012aqds/ls1012aqds.c | 4 +- board/freescale/ls1012ardb/ls1012ardb.c | 3 +- include/fsl_immap.h | 51 ++++++++++++++++++++++ 9 files changed, 88 insertions(+), 56 deletions(-) diff --git a/README b/README index 3735916..a66a7ae 100644 --- a/README +++ b/README @@ -312,6 +312,15 @@ Many of the options are named exactly as the corresponding Linux kernel configuration options.
