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 <mathieu@codeaurora.org> +--- + 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 +@@ -341,7 +341,7 @@ config ARCH_MULTIPLATFORM + depends on MMU + select ARM_HAS_SG_CHAIN + select ARM_PATCH_PHYS_VIRT +- select AUTO_ZRELADDR ++ select AUTO_ZRELADDR if !ARCH_QCOM + select TIMER_OF + select COMMON_CLK + select GENERIC_CLOCKEVENTS +--- a/arch/arm/Makefile ++++ b/arch/arm/Makefile +@@ -255,9 +255,11 @@ 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-4.19/0061-mtd-rootfs-conflicts-with-OpenWrt-auto-mounting.patch b/target/linux/ipq806x/patches-4.19/0061-mtd-rootfs-conflicts-with-OpenWrt-auto-mounting.patch new file mode 100644 index 0000000000..a4a957545b --- /dev/null +++ b/target/linux/ipq806x/patches-4.19/0061-mtd-rootfs-conflicts-with-OpenWrt-auto-mounting.patch @@ -0,0 +1,23 @@ +From 5001f2e1a325b68dbf225bd17f69a4d3d975cca5 Mon Sep 17 00:00:00 2001 +From: John Crispin <john@phrozen.org> +Date: Thu, 9 Mar 2017 09:31:44 +0100 +Subject: [PATCH 61/69] mtd: "rootfs" conflicts with OpenWrt auto mounting + +Signed-off-by: John Crispin <john@phrozen.org> +--- + drivers/mtd/qcom_smem_part.c | 4 ++++ + 1 file changed, 4 insertions(+) + +--- a/drivers/mtd/qcom_smem_part.c ++++ b/drivers/mtd/qcom_smem_part.c +@@ -189,6 +189,10 @@ static int parse_qcom_smem_partitions(st + m_part->size = le32_to_cpu(s_part->size) * (*smem_blksz); + m_part->offset = le32_to_cpu(s_part->start) * (*smem_blksz); + ++ /* "rootfs" conflicts with OpenWrt auto mounting */ ++ if (mtd_type_is_nand(master) && !strcmp(m_part->name, "rootfs")) ++ m_part->name = "ubi"; ++ + /* + * The last SMEM partition may have its size marked as + * something like 0xffffffff, which means "until the end of the diff --git a/target/linux/ipq806x/patches-4.19/0062-ipq806x-gcc-Added-the-enable-regs-and-mask-for-PRNG.patch b/target/linux/ipq806x/patches-4.19/0062-ipq806x-gcc-Added-the-enable-regs-and-mask-for-PRNG.patch new file mode 100644 index 0000000000..717934315a --- /dev/null +++ b/target/linux/ipq806x/patches-4.19/0062-ipq806x-gcc-Added-the-enable-regs-and-mask-for-PRNG.patch @@ -0,0 +1,25 @@ +From a16fcf911a020e46439a3bb3e702463fc3159831 Mon Sep 17 00:00:00 2001 +From: Abhishek Sahu <absahu@codeaurora.org> +Date: Wed, 18 Nov 2015 12:38:56 +0530 +Subject: [PATCH 62/69] ipq806x: gcc: Added the enable regs and mask for PRNG + +kernel got hanged while reading from /dev/hwrng at the +time of PRNG clock enable + +Change-Id: I89856c7e19e6639508e6a2774304583a3ec91172 +Signed-off-by: Abhishek Sahu <absahu@codeaurora.org> +--- + drivers/clk/qcom/gcc-ipq806x.c | 2 ++ + 1 file changed, 2 insertions(+) + +--- a/drivers/clk/qcom/gcc-ipq806x.c ++++ b/drivers/clk/qcom/gcc-ipq806x.c +@@ -1233,6 +1233,8 @@ static struct clk_rcg prng_src = { + .parent_map = gcc_pxo_pll8_map, + }, + .clkr = { ++ .enable_reg = 0x2e80, ++ .enable_mask = BIT(11), + .hw.init = &(struct clk_init_data){ + .name = "prng_src", + .parent_names = gcc_pxo_pll8, diff --git a/target/linux/ipq806x/patches-4.19/0063-1-ipq806x-tsens-driver.patch b/target/linux/ipq806x/patches-4.19/0063-1-ipq806x-tsens-driver.patch new file mode 100644 index 0000000000..685b0c3ce1 --- /dev/null +++ b/target/linux/ipq806x/patches-4.19/0063-1-ipq806x-tsens-driver.patch @@ -0,0 +1,627 @@ +From 3302e1e1a3cfa4e67fda2a61d6f0c42205d40932 Mon Sep 17 00:00:00 2001 +From: Rajith Cherian <rajith@codeaurora.org> +Date: Tue, 14 Feb 2017 18:30:43 +0530 +Subject: [PATCH] ipq8064: tsens: Base tsens driver for IPQ8064 + +Add TSENS driver template to support IPQ8064. +This is a base file copied from tsens-8960.c + +Change-Id: I47c573fdfa2d898243c6a6ba952d1632f91391f7 +Signed-off-by: Rajith Cherian <rajith@codeaurora.org> + +ipq8064: tsens: TSENS driver support for IPQ8064 + +Support for IPQ8064 tsens driver.

Currently, it does not +generate any error since bootloader enables the pcie_phy_clk +but the same error is coming during probe, if bootloader +disables pcie_phy_clk. + +Change-Id: Ib29c154d10eb64363d9cc982ce5fd8107af5627d +Signed-off-by: Abhishek Sahu <absahu@codeaurora.org> +--- + drivers/pci/host/pcie-qcom.c | 16 +++++++--------- + 1 file changed, 7 insertions(+), 9 deletions(-) + +--- a/drivers/pci/dwc/pcie-qcom.c ++++ b/drivers/pci/dwc/pcie-qcom.c +@@ -407,6 +407,7 @@ static void qcom_pcie_deinit_2_1_0(struc + { + struct qcom_pcie_resources_2_1_0 *res = &pcie->res.v2_1_0; + ++ clk_disable_unprepare(res->phy_clk); + reset_control_assert(res->pci_reset); + reset_control_assert(res->axi_reset); + reset_control_assert(res->ahb_reset); +@@ -415,7 +416,6 @@ static void qcom_pcie_deinit_2_1_0(struc + reset_control_assert(res->ext_reset); + clk_disable_unprepare(res->iface_clk); + clk_disable_unprepare(res->core_clk); +- clk_disable_unprepare(res->phy_clk); + clk_disable_unprepare(res->aux_clk); + clk_disable_unprepare(res->ref_clk); + regulator_disable(res->vdda); +@@ -472,12 +472,6 @@ static int qcom_pcie_init_2_1_0(struct q + goto err_clk_core; + } + +- ret = clk_prepare_enable(res->phy_clk); +- if (ret) { +- dev_err(dev, "cannot prepare/enable phy clock\n"); +- goto err_clk_phy; +- } +- + ret = clk_prepare_enable(res->aux_clk); + if (ret) { + dev_err(dev, "cannot prepare/enable aux clock\n"); +@@ -541,6 +535,12 @@ static int qcom_pcie_init_2_1_0(struct q + return ret; + } + ++ ret = clk_prepare_enable(res->phy_clk); ++ if (ret) { ++ dev_err(dev, "cannot prepare/enable phy clock\n"); ++ goto err_deassert_ahb; ++ } ++ + /* wait for clock acquisition */ + usleep_range(1000, 1500); + if (pcie->force_gen1) { +@@ -566,8 +566,6 @@ err_deassert_ahb: + err_clk_ref: + clk_disable_unprepare(res->aux_clk); + err_clk_aux: +- clk_disable_unprepare(res->phy_clk); +-err_clk_phy: + clk_disable_unprepare(res->core_clk); + err_clk_core: + clk_disable_unprepare(res->iface_clk); diff --git a/target/linux/ipq806x/patches-4.19/0071-9-pcie-qcom-change-duplicate-pci-reset-to-phy-reset.patch b/target/linux/ipq806x/patches-4.19/0071-9-pcie-qcom-change-duplicate-pci-reset-to-phy-reset.patch new file mode 100644 index 0000000000..227a1b4e7a --- /dev/null +++ b/target/linux/ipq806x/patches-4.19/0071-9-pcie-qcom-change-duplicate-pci-reset-to-phy-reset.patch @@ -0,0 +1,25 @@ +From 1a9c48123bd09f75562b6a2ee0f0a7b2d533cd45 Mon Sep 17 00:00:00 2001 +From: Abhishek Sahu <absahu@codeaurora.org> +Date: Thu, 22 Dec 2016 11:50:49 +0530 +Subject: pcie: qcom: change duplicate pci reset to phy reset + +The deinit issues reset_control_assert for pci twice and +does not contain phy reset. + +Change-Id: Iba849963c7e5f9a2a1063f0e2e89635df70b8a99 +Signed-off-by: Abhishek Sahu <absahu@codeaurora.org> +--- + drivers/pci/host/pcie-qcom.c | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +--- a/drivers/pci/dwc/pcie-qcom.c ++++ b/drivers/pci/dwc/pcie-qcom.c +@@ -408,7 +408,7 @@ static void qcom_pcie_deinit_2_1_0(struc + struct qcom_pcie_resources_2_1_0 *res = &pcie->res.v2_1_0; + + clk_disable_unprepare(res->phy_clk); +- reset_control_assert(res->pci_reset); ++ reset_control_assert(res->phy_reset); + reset_control_assert(res->axi_reset); + reset_control_assert(res->ahb_reset); + reset_control_assert(res->por_reset); diff --git a/target/linux/ipq806x/patches-4.19/0072-add-ipq806x-with-no-clocks.patch b/target/linux/ipq806x/patches-4.19/0072-add-ipq806x-with-no-clocks.patch new file mode 100644 index 0000000000..035281f66a --- /dev/null +++ b/target/linux/ipq806x/patches-4.19/0072-add-ipq806x-with-no-clocks.patch @@ -0,0 +1,12 @@ +--- a/drivers/firmware/qcom_scm.c ++++ b/drivers/firmware/qcom_scm.c +@@ -422,6 +422,9 @@ static const struct of_device_id qcom_sc + { .compatible = "qcom,scm-msm8996", + .data = NULL, /* no clocks */ + }, ++ { .compatible = "qcom,scm-ipq806x", ++ .data = NULL, /* no clocks */ ++ }, + { .compatible = "qcom,scm", + .data = (void *)(SCM_HAS_CORE_CLK + | SCM_HAS_IFACE_CLK diff --git a/target/linux/ipq806x/patches-4.19/0073-pinctrl-qom-use-scm_call-to-route-GPIO-irq-to-Apps.patch b/target/linux/ipq806x/patches-4.19/0073-pinctrl-qom-use-scm_call-to-route-GPIO-irq-to-Apps.patch new file mode 100644 index 0000000000..1507686456 --- /dev/null +++ b/target/linux/ipq806x/patches-4.19/0073-pinctrl-qom-use-scm_call-to-route-GPIO-irq-to-Apps.patch @@ -0,0 +1,183 @@ +From 2034addc7e193dc81d7ca60d8884832751b76758 Mon Sep 17 00:00:00 2001 +From: Ajay Kishore <akisho@codeaurora.org> +Date: Tue, 24 Jan 2017 14:14:16 +0530 +Subject: pinctrl: qcom: use scm_call to route GPIO irq to Apps + +For IPQ806x targets, TZ protects the registers that are used to +configure the routing of interrupts to a target processor. +To resolve this, this patch uses scm call to route GPIO interrupts +to application processor.
