From b7f2bbfff6dcc2d5989bb1d20500c431f7927daf Mon Sep 17 00:00:00 2001 From: Prabhakar Kushwaha Date: Fri, 3 Jun 2016 18:41:31 +0530 Subject: armv8: fsl-layerscape: Add support of QorIQ LS1012A SoC The QorIQ LS1012A processor, optimized for battery-backed or USB-powered, integrates a single ARM Cortex-A53 core with a hardware packet forwarding engine and high-speed interfaces to deliver line-rate networking performance. This patch add support of LS1012A SoC along with - Update platform & DDR clock read logic as per SVR - Define MMDC controller register set. - Update LUT base address for PCIe - Avoid L3 platform cache compilation - Update USB address, errata - SerDes table - Added CSU IDs for SDHC2, SAI-1 to SAI-4 Signed-off-by: Calvin Johnson Signed-off-by: Makarand Pawagi Signed-off-by: Prabhakar Kushwaha Reviewed-by: York Sun --- arch/arm/cpu/armv8/fsl-layerscape/Makefile | 4 ++ arch/arm/cpu/armv8/fsl-layerscape/doc/README.soc | 43 +++++++++++++ .../arm/cpu/armv8/fsl-layerscape/fsl_lsch2_speed.c | 11 ++++ arch/arm/cpu/armv8/fsl-layerscape/lowlevel.S | 2 + arch/arm/cpu/armv8/fsl-layerscape/ls1012a_serdes.c | 74 ++++++++++++++++++++++ arch/arm/cpu/armv8/fsl-layerscape/soc.c | 2 + 6 files changed, 136 insertions(+) create mode 100644 arch/arm/cpu/armv8/fsl-layerscape/ls1012a_serdes.c (limited to 'arch/arm/cpu') diff --git a/arch/arm/cpu/armv8/fsl-layerscape/Makefile b/arch/arm/cpu/armv8/fsl-layerscape/Makefile index 5f86ef90d2..eb2cbc3f7e 100644 --- a/arch/arm/cpu/armv8/fsl-layerscape/Makefile +++ b/arch/arm/cpu/armv8/fsl-layerscape/Makefile @@ -28,3 +28,7 @@ endif ifneq ($(CONFIG_LS1043A),) obj-$(CONFIG_SYS_HAS_SERDES) += ls1043a_serdes.o endif + +ifneq ($(CONFIG_LS1012A),) +obj-$(CONFIG_SYS_HAS_SERDES) += ls1012a_serdes.o +endif diff --git a/arch/arm/cpu/armv8/fsl-layerscape/doc/README.soc b/arch/arm/cpu/armv8/fsl-layerscape/doc/README.soc index a4130cee50..8eee016f11 100644 --- a/arch/arm/cpu/armv8/fsl-layerscape/doc/README.soc +++ b/arch/arm/cpu/armv8/fsl-layerscape/doc/README.soc @@ -2,6 +2,7 @@ SoC overview 1.
