This automatically calculate ZRELADDR by -masking PHYS_OFFSET with 0xf8000000. - -However, on IPQ806x, the first ~20MB of RAM is reserved for the hardware -network accelerators, and the bootloader removes this section from the -layout passed from the ATAGS (when used). - -For newer bootloader, when DT is used, this is not a problem, we just -reserve this memory in the device tree. But if the bootloader doesn't -have DT support, then ATAGS have to be used. In this case, the ARM -decompressor will position the kernel in this low mem, which will not be -in the RAM section mapped by the bootloader, which means the kernel will -freeze in the middle of the boot process trying to map the memory. - -As a work around, this patch allows disabling AUTO_ZRELADDR when -ARCH_QCOM is selected. It makes the zImage usage possible on bootloaders -which don't support device-tree, which is the case on certain early -IPQ806x based designs. - -Signed-off-by: Mathieu Olivari ---- - arch/arm/Kconfig | 2 +- - arch/arm/Makefile | 2 ++ - arch/arm/mach-qcom/Makefile.boot | 1 + - 3 files changed, 4 insertions(+), 1 deletion(-) - create mode 100644 arch/arm/mach-qcom/Makefile.boot - ---- a/arch/arm/Kconfig -+++ b/arch/arm/Kconfig -@@ -314,7 +314,7 @@ config ARCH_MULTIPLATFORM - select ARCH_WANT_OPTIONAL_GPIOLIB - select ARM_HAS_SG_CHAIN - select ARM_PATCH_PHYS_VIRT -- select AUTO_ZRELADDR -+ select AUTO_ZRELADDR if !ARCH_QCOM - select CLKSRC_OF - select COMMON_CLK - select GENERIC_CLOCKEVENTS ---- a/arch/arm/Makefile -+++ b/arch/arm/Makefile -@@ -241,9 +241,11 @@ MACHINE := arch/arm/mach-$(word 1,$(mac - else - MACHINE := - endif -+ifeq ($(CONFIG_ARCH_QCOM),) - ifeq ($(CONFIG_ARCH_MULTIPLATFORM),y) - MACHINE := - endif -+endif - - machdirs := $(patsubst %,arch/arm/mach-%/,$(machine-y)) - platdirs := $(patsubst %,arch/arm/plat-%/,$(sort $(plat-y))) ---- /dev/null -+++ b/arch/arm/mach-qcom/Makefile.boot -@@ -0,0 +1 @@ -+zreladdr-y+= 0x42208000 diff --git a/target/linux/ipq806x/patches-4.0/700-clk-qcom-Add-support-for-NSS-GMAC-clocks-and-resets.patch b/target/linux/ipq806x/patches-4.0/700-clk-qcom-Add-support-for-NSS-GMAC-clocks-and-resets.patch deleted file mode 100644 index 1b9d47bf1b..0000000000 --- a/target/linux/ipq806x/patches-4.0/700-clk-qcom-Add-support-for-NSS-GMAC-clocks-and-resets.patch +++ /dev/null @@ -1,733 +0,0 @@ -From 2fbb18f85826a9ba308fedb2cf90d3a661a39fd7 Mon Sep 17 00:00:00 2001 -From: Stephen Boyd -Date: Fri, 27 Mar 2015 00:16:14 -0700 -Subject: [PATCH] clk: qcom: Add support for NSS/GMAC clocks and resets - -Add the NSS/GMAC clocks and the TCM clock and NSS resets. - -Signed-off-by: Stephen Boyd ---- - drivers/clk/qcom/gcc-ipq806x.c | 594 ++++++++++++++++++++++++++- - drivers/clk/qcom/gcc-ipq806x.c.rej | 50 +++ - include/dt-bindings/clock/qcom,gcc-ipq806x.h | 2 + - include/dt-bindings/reset/qcom,gcc-ipq806x.h | 43 ++ - 4 files changed, 688 insertions(+), 1 deletion(-) - create mode 100644 drivers/clk/qcom/gcc-ipq806x.c.rej - ---- a/drivers/clk/qcom/gcc-ipq806x.c -+++ b/drivers/clk/qcom/gcc-ipq806x.c -@@ -220,11 +220,46 @@ static struct clk_regmap pll14_vote = { - }, - };

For +example, consider a case where a PLL feeds into a divider. +Initially the divider is set to divide by 1 and the PLL is +running fairly slow (100MHz). The downstream consumer of the +divider output can only handle rates =< 400 MHz, but the divider +can only choose between divisors of 1 and 4. + + +-----+ +----------------+ + | PLL |-->| div 1 or div 4 |---> consumer device + +-----+ +----------------+ + +To achieve a rate of 400MHz on the output of the divider, we +would have to set the rate of the PLL to 1.6 GHz and then divide +it by 4. The current code would set the PLL to 1.6GHz first while +the divider is still set to 1, thus causing the downstream +consumer of the clock to receive a few clock cycles of 1.6GHz +clock (far beyond it's maximum acceptable rate). We should be +changing the divider first before increasing the PLL rate to +avoid this problem. + +Therefore, set the rate of any child clocks that are increasing +in rate from their current rate so that they can increase their +dividers if necessary.

This automatically calculate ZRELADDR by +masking PHYS_OFFSET with 0xf8000000. + +However, on IPQ806x, the first ~20MB of RAM is reserved for the hardware +network accelerators, and the bootloader removes this section from the +layout passed from the ATAGS (when used). + +For newer bootloader, when DT is used, this is not a problem, we just +reserve this memory in the device tree. But if the bootloader doesn't +have DT support, then ATAGS have to be used. In this case, the ARM +decompressor will position the kernel in this low mem, which will not be +in the RAM section mapped by the bootloader, which means the kernel will +freeze in the middle of the boot process trying to map the memory. + +As a work around, this patch allows disabling AUTO_ZRELADDR when +ARCH_QCOM is selected. It makes the zImage usage possible on bootloaders +which don't support device-tree, which is the case on certain early +IPQ806x based designs. + +Signed-off-by: Mathieu Olivari +--- + arch/arm/Kconfig | 2 +- + arch/arm/Makefile | 2 ++ + arch/arm/mach-qcom/Makefile.boot | 1 + + 3 files changed, 4 insertions(+), 1 deletion(-) + create mode 100644 arch/arm/mach-qcom/Makefile.boot + +--- a/arch/arm/Kconfig ++++ b/arch/arm/Kconfig +@@ -320,7 +320,7 @@ config ARCH_MULTIPLATFORM + select ARCH_WANT_OPTIONAL_GPIOLIB + select ARM_HAS_SG_CHAIN + select ARM_PATCH_PHYS_VIRT +- select AUTO_ZRELADDR ++ select AUTO_ZRELADDR if !ARCH_QCOM + select CLKSRC_OF + select COMMON_CLK + select GENERIC_CLOCKEVENTS +--- a/arch/arm/Makefile ++++ b/arch/arm/Makefile +@@ -240,9 +240,11 @@ MACHINE := arch/arm/mach-$(word 1,$(mac + else + MACHINE := + endif ++ifeq ($(CONFIG_ARCH_QCOM),) + ifeq ($(CONFIG_ARCH_MULTIPLATFORM),y) + MACHINE := + endif ++endif + + machdirs := $(patsubst %,arch/arm/mach-%/,$(machine-y)) + platdirs := $(patsubst %,arch/arm/plat-%/,$(sort $(plat-y))) +--- /dev/null ++++ b/arch/arm/mach-qcom/Makefile.boot +@@ -0,0 +1 @@ ++zreladdr-y+= 0x42208000 diff --git a/target/linux/ipq806x/patches-4.1/700-clk-qcom-Add-support-for-NSS-GMAC-clocks-and-resets.patch b/target/linux/ipq806x/patches-4.1/700-clk-qcom-Add-support-for-NSS-GMAC-clocks-and-resets.patch new file mode 100644 index 0000000000..dfe716953f --- /dev/null +++ b/target/linux/ipq806x/patches-4.1/700-clk-qcom-Add-support-for-NSS-GMAC-clocks-and-resets.patch @@ -0,0 +1,734 @@ +From 2fbb18f85826a9ba308fedb2cf90d3a661a39fd7 Mon Sep 17 00:00:00 2001 +From: Stephen Boyd +Date: Fri, 27 Mar 2015 00:16:14 -0700 +Subject: [PATCH] clk: qcom: Add support for NSS/GMAC clocks and resets + +Add the NSS/GMAC clocks and the TCM clock and NSS resets. + +Signed-off-by: Stephen Boyd +--- + drivers/clk/qcom/gcc-ipq806x.c | 594 ++++++++++++++++++++++++++- + drivers/clk/qcom/gcc-ipq806x.c.rej | 50 +++ + include/dt-bindings/clock/qcom,gcc-ipq806x.h | 2 + + include/dt-bindings/reset/qcom,gcc-ipq806x.h | 43 ++ + 4 files changed, 688 insertions(+), 1 deletion(-) + create mode 100644 drivers/clk/qcom/gcc-ipq806x.c.rej + +--- a/drivers/clk/qcom/gcc-ipq806x.c ++++ b/drivers/clk/qcom/gcc-ipq806x.c +@@ -220,12 +220,47 @@ static struct clk_regmap pll14_vote = { + }, + };
