From 53ffd67d944fa23037e7f97e583fae300d4367f7 Mon Sep 17 00:00:00 2001 From: Prabhakar Kushwaha Date: Sat, 23 Apr 2016 15:23:52 +0530 Subject: [PATCH 13/93] armv8: fsl-layerscape: Add support of QorIQ LS1012A SoC [context adjustment] 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 Signed-off-by: Rajat Srivastava Signed-off-by: Rajesh Bhagat Signed-off-by: Calvin Johnson Signed-off-by: Prabhakar Kushwaha Integrated-by: Jiang Yutang --- arch/arm/cpu/armv8/fsl-layerscape/Makefile | 4 ++ .../arm/cpu/armv8/fsl-layerscape/fsl_lsch2_speed.c | 24 +++++-- 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 | 6 +- arch/arm/include/asm/arch-fsl-layerscape/config.h | 32 +++++++++ arch/arm/include/asm/arch-fsl-layerscape/cpu.h | 1 + .../include/asm/arch-fsl-layerscape/fsl_serdes.h | 1 + .../include/asm/arch-fsl-layerscape/immap_lsch2.h | 4 ++ arch/arm/include/asm/arch-fsl-layerscape/soc.h | 1 + include/fsl_mmdc.h | 53 ++++++++++++++ include/linux/usb/xhci-fsl.h | 4 ++ 12 files changed, 199 insertions(+), 7 deletions(-) create mode 100644 arch/arm/cpu/armv8/fsl-layerscape/ls1012a_serdes.c create mode 100644 include/fsl_mmdc.h diff --git a/arch/arm/cpu/armv8/fsl-layerscape/Makefile b/arch/arm/cpu/armv8/fsl-layerscape/Makefile index 27bfeb1..03f73d1 100644 --- a/arch/arm/cpu/armv8/fsl-layerscape/Makefile +++ b/arch/arm/cpu/armv8/fsl-layerscape/Makefile @@ -33,3 +33,7 @@ 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/fsl_lsch2_speed.c b/arch/arm/cpu/armv8/fsl-layerscape/fsl_lsch2_speed.c index 078b087..63e5bed 100644 --- a/arch/arm/cpu/armv8/fsl-layerscape/fsl_lsch2_speed.c +++ b/arch/arm/cpu/armv8/fsl-layerscape/fsl_lsch2_speed.c @@ -33,6 +33,7 @@ void get_sys_info(struct sys_info *sys_info) #endif struct ccsr_clk *clk = (void *)(CONFIG_SYS_FSL_CLK_ADDR);
