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 -@@ -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-4.14/0061-mtd-rootfs-conflicts-with-OpenWrt-auto-mounting.patch b/target/linux/ipq806x/patches-4.14/0061-mtd-rootfs-conflicts-with-OpenWrt-auto-mounting.patch deleted file mode 100644 index a4a957545b..0000000000 --- a/target/linux/ipq806x/patches-4.14/0061-mtd-rootfs-conflicts-with-OpenWrt-auto-mounting.patch +++ /dev/null @@ -1,23 +0,0 @@ -From 5001f2e1a325b68dbf225bd17f69a4d3d975cca5 Mon Sep 17 00:00:00 2001 -From: John Crispin -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 ---- - 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-4.14/0062-ipq806x-gcc-Added-the-enable-regs-and-mask-for-PRNG.patch b/target/linux/ipq806x/patches-4.14/0062-ipq806x-gcc-Added-the-enable-regs-and-mask-for-PRNG.patch deleted file mode 100644 index a3e0a1dc5d..0000000000 --- a/target/linux/ipq806x/patches-4.14/0062-ipq806x-gcc-Added-the-enable-regs-and-mask-for-PRNG.patch +++ /dev/null @@ -1,25 +0,0 @@ -From a16fcf911a020e46439a3bb3e702463fc3159831 Mon Sep 17 00:00:00 2001 -From: Abhishek Sahu -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 ---- - 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 -@@ -1234,6 +1234,8 @@ 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-4.14/0063-1-ipq806x-tsens-driver.patch b/target/linux/ipq806x/patches-4.14/0063-1-ipq806x-tsens-driver.patch deleted file mode 100644 index 685b0c3ce1..0000000000 --- a/target/linux/ipq806x/patches-4.14/0063-1-ipq806x-tsens-driver.patch +++ /dev/null @@ -1,627 +0,0 @@ -From 3302e1e1a3cfa4e67fda2a61d6f0c42205d40932 Mon Sep 17 00:00:00 2001 -From: Rajith Cherian -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 - -ipq8064: tsens: TSENS driver support for IPQ8064 - -Support for IPQ8064 tsens driver.

And finally, it helps us transition the GCC driver to use -RPM clocks when that configuration is enabled. - -Cc: Georgi Djakov -Signed-off-by: Stephen Boyd ---- - drivers/clk/qcom/gcc-apq8084.c | 16 +++++++--------- - drivers/clk/qcom/gcc-ipq806x.c | 14 ++++++-------- - drivers/clk/qcom/gcc-msm8660.c | 15 +++++++-------- - drivers/clk/qcom/gcc-msm8960.c | 14 ++++++-------- - drivers/clk/qcom/gcc-msm8974.c | 17 +++++++---------- - 5 files changed, 33 insertions(+), 43 deletions(-) - ---- a/drivers/clk/qcom/gcc-apq8084.c -+++ b/drivers/clk/qcom/gcc-apq8084.c -@@ -3607,18 +3607,16 @@ MODULE_DEVICE_TABLE(of, gcc_apq8084_matc - - static int gcc_apq8084_probe(struct platform_device *pdev) - { -- struct clk *clk; -+ int ret; - struct device *dev = &pdev->dev; - -- /* Temporary until RPM clocks supported */ -- clk = clk_register_fixed_rate(dev, "xo", NULL, CLK_IS_ROOT, 19200000); -- if (IS_ERR(clk)) -- return PTR_ERR(clk); -+ ret = qcom_cc_register_board_clk(dev, "xo_board", "xo", 19200000); -+ if (ret) -+ return ret; - -- clk = clk_register_fixed_rate(dev, "sleep_clk_src", NULL, -- CLK_IS_ROOT, 32768); -- if (IS_ERR(clk)) -- return PTR_ERR(clk); -+ ret = qcom_cc_register_sleep_clk(dev); -+ if (ret) -+ return ret; - - return qcom_cc_probe(pdev, &gcc_apq8084_desc); - } ---- a/drivers/clk/qcom/gcc-ipq806x.c -+++ b/drivers/clk/qcom/gcc-ipq806x.c -@@ -3023,19 +3023,17 @@ MODULE_DEVICE_TABLE(of, gcc_ipq806x_matc - - static int gcc_ipq806x_probe(struct platform_device *pdev) - { -- struct clk *clk; - struct device *dev = &pdev->dev; - struct regmap *regmap; - int ret; - -- /* Temporary until RPM clocks supported */ -- clk = clk_register_fixed_rate(dev, "cxo", NULL, CLK_IS_ROOT, 25000000); -- if (IS_ERR(clk)) -- return PTR_ERR(clk); -+ ret = qcom_cc_register_board_clk(dev, "cxo_board", "cxo", 25000000); -+ if (ret) -+ return ret; - -- clk = clk_register_fixed_rate(dev, "pxo", NULL, CLK_IS_ROOT, 25000000); -- if (IS_ERR(clk)) -- return PTR_ERR(clk); -+ ret = qcom_cc_register_board_clk(dev, "pxo_board", "pxo", 25000000); -+ if (ret) -+ return ret; - - ret = qcom_cc_probe(pdev, &gcc_ipq806x_desc); - if (ret) ---- a/drivers/clk/qcom/gcc-msm8660.c -+++ b/drivers/clk/qcom/gcc-msm8660.c -@@ -2720,17 +2720,16 @@ MODULE_DEVICE_TABLE(of, gcc_msm8660_matc - - static int gcc_msm8660_probe(struct platform_device *pdev) - { -- struct clk *clk; -+ int ret; - struct device *dev = &pdev->dev; - -- /* Temporary until RPM clocks supported */ -- clk = clk_register_fixed_rate(dev, "cxo", NULL, CLK_IS_ROOT, 19200000); -- if (IS_ERR(clk)) -- return PTR_ERR(clk); -+ ret = qcom_cc_register_board_clk(dev, "cxo_board", "cxo", 19200000); -+ if (ret) -+ return ret; - -- clk = clk_register_fixed_rate(dev, "pxo", NULL, CLK_IS_ROOT, 27000000); -- if (IS_ERR(clk)) -- return PTR_ERR(clk); -+ ret = qcom_cc_register_board_clk(dev, "pxo_board", "pxo", 27000000); -+ if (ret) -+ return ret; - - return qcom_cc_probe(pdev, &gcc_msm8660_desc); - } ---- a/drivers/clk/qcom/gcc-msm8960.c -+++ b/drivers/clk/qcom/gcc-msm8960.c -@@ -3503,7 +3503,6 @@ MODULE_DEVICE_TABLE(of, gcc_msm8960_matc - - static int gcc_msm8960_probe(struct platform_device *pdev) - { -- struct clk *clk; - struct device *dev = &pdev->dev; - const struct of_device_id *match; - struct platform_device *tsens; -@@ -3513,14 +3512,13 @@ static int gcc_msm8960_probe(struct plat - if (!match) - return -EINVAL; - -- /* Temporary until RPM clocks supported */ -- clk = clk_register_fixed_rate(dev, "cxo", NULL, CLK_IS_ROOT, 19200000); -- if (IS_ERR(clk)) -- return PTR_ERR(clk); -+ ret = qcom_cc_register_board_clk(dev, "cxo_board", "cxo", 19200000); -+ if (ret) -+ return ret; - -- clk = clk_register_fixed_rate(dev, "pxo", NULL, CLK_IS_ROOT, 27000000); -- if (IS_ERR(clk)) -- return PTR_ERR(clk); -+ ret = qcom_cc_register_board_clk(dev, "pxo_board", "pxo", 27000000); -+ if (ret) -+ return ret; - - ret = qcom_cc_probe(pdev, match->data); - if (ret) ---- a/drivers/clk/qcom/gcc-msm8974.c -+++ b/drivers/clk/qcom/gcc-msm8974.c -@@ -2717,7 +2717,7 @@ static void msm8974_pro_clock_override(v - - static int gcc_msm8974_probe(struct platform_device *pdev) - { -- struct clk *clk; -+ int ret; - struct device *dev = &pdev->dev; - bool pro; - const struct of_device_id *id; -@@ -2730,16 +2730,13 @@ static int gcc_msm8974_probe(struct plat - if (pro) - msm8974_pro_clock_override(); - -- /* Temporary until RPM clocks supported */ -- clk = clk_register_fixed_rate(dev, "xo", NULL, CLK_IS_ROOT, 19200000); -- if (IS_ERR(clk)) -- return PTR_ERR(clk); -- -- /* Should move to DT node?

The lifetime of those -variables is determined by the watchdog driver. However, the lifetime -of variables used by the watchdog core differs from the lifetime of -struct watchdog_device. To remedy this situation, watchdog drivers -can implement ref and unref callbacks, to be used by the watchdog -core to lock struct watchdog_device in memory. - -While this solves the immediate problem, it depends on watchdog drivers -to actually implement the ref/unref callbacks. This is error prone, -often not implemented in the first place, or not implemented correctly. - -To solve the problem without requiring driver support, split the variables -in struct watchdog_device into two data structures - one for variables -associated with the watchdog driver, one for variables associated with -the watchdog core. With this approach, the watchdog core can keep track -of its variable lifetime and no longer depends on ref/unref callbacks -in the driver. As a side effect, some of the variables originally in -struct watchdog_driver are now private to the watchdog core and no longer -visible in watchdog drivers. - -As a side effect of the changes made, an ioctl will now always fail -with -ENODEV after a watchdog device was unregistered with the character -device still open. Previously, it would only fail with -ENODEV in some -situations. Also, ioctl operations are now atomic from driver perspective. -With this change, it is now guaranteed that the driver will not unregister -a watchdog between a timeout change and the subsequent ping. - -The 'ref' and 'unref' callbacks in struct watchdog_driver are no longer -used and marked as deprecated. - -Signed-off-by: Guenter Roeck -Signed-off-by: Wim Van Sebroeck ---- - Documentation/watchdog/watchdog-kernel-api.txt | 45 +-- - drivers/watchdog/watchdog_core.c | 2 - - drivers/watchdog/watchdog_dev.c | 383 +++++++++++++------------ - include/linux/watchdog.h | 22 +- - 4 files changed, 218 insertions(+), 234 deletions(-) - ---- a/Documentation/watchdog/watchdog-kernel-api.txt -+++ b/Documentation/watchdog/watchdog-kernel-api.txt -@@ -44,7 +44,6 @@ The watchdog device structure looks like - - struct watchdog_device { - int id; -- struct cdev cdev; - struct device *dev; - struct device *parent; - const struct watchdog_info *info; -@@ -56,7 +55,7 @@ struct watchdog_device { - struct notifier_block reboot_nb; - struct notifier_block restart_nb; - void *driver_data; -- struct mutex lock; -+ struct watchdog_core_data *wd_data; - unsigned long status; - struct list_head deferred; - }; -@@ -66,8 +65,6 @@ It contains following fields: - /dev/watchdog0 cdev (dynamic major, minor 0) as well as the old - /dev/watchdog miscdev.

These IPs provide a -broader interface for external slow peripheral devices such as LCD and -NAND/NOR flash memory or SRAM like interfaces. - -We add support for the NAND controller found within EBI2. For the SoCs -of our interest, we only use the NAND controller within EBI2. Therefore, -it's safe for us to assume that the NAND controller is a standalone block -within the SoC. - -The controller supports 512B, 2kB, 4kB and 8kB page 8-bit and 16-bit NAND -flash devices. It contains a HW ECC block that supports BCH ECC (4, 8 and -16 bit correction/step) and RS ECC(4 bit correction/step) that covers main -and spare data. The controller contains an internal 512 byte page buffer -to which we read/write via DMA. The EBI2 type NAND controller uses ADM DMA -for register read/write and data transfers. The controller performs page -reads and writes at a codeword/step level of 512 bytes. It can support up -to 2 external chips of different configurations. - -The driver prepares register read and write configuration descriptors for -each codeword, followed by data descriptors to read or write data from the -controller's internal buffer. It uses a single ADM DMA channel that we get -via dmaengine API. The controller requires 2 ADM CRCIs for command and -data flow control. These are passed via DT. - -The ecc layout used by the controller is syndrome like, but we can't use -the standard syndrome ecc ops because of several reasons. First, the amount -of data bytes covered by ecc isn't same in each step. Second, writing to -free oob space requires us writing to the entire step in which the oob -lies. This forces us to create our own ecc ops. - -One more difference is how the controller accesses the bad block marker. -The controller ignores reading the marker when ECC is enabled. ECC needs -to be explicity disabled to read or write to the bad block marker. For -this reason, we use the newly created flag NAND_BBT_ACCESS_BBM_RAW to -read the factory provided bad block markers. - -v3: -- Refactor dma functions for maximum reuse -- Use dma_slave_confing on stack -- optimize and clean upempty_page_fixup using memchr_inv -- ensure portability with dma register reads using le32_* funcs -- use NAND_USE_BOUNCE_BUFFER instead of doing it ourselves -- fix handling of return values of dmaengine funcs -- constify wherever possible -- Remove dependency on ADM DMA in Kconfig -- Misc fixes and clean ups - -v2: -- Use new BBT flag that allows us to read BBM in raw mode -- reduce memcpy-s in the driver -- some refactor and clean ups because of above changes - -Reviewed-by: Andy Gross -Signed-off-by: Archit Taneja - ---- -drivers/mtd/nand/Kconfig | 7 + - drivers/mtd/nand/Makefile | 1 + - drivers/mtd/nand/qcom_nandc.c | 1913 +++++++++++++++++++++++++++++++++++++++++ - 3 files changed, 1921 insertions(+) - create mode 100644 drivers/mtd/nand/qcom_nandc.c - ---- a/drivers/mtd/nand/Kconfig -+++ b/drivers/mtd/nand/Kconfig -@@ -546,4 +546,11 @@ config MTD_NAND_HISI504 - help - Enables support for NAND controller on Hisilicon SoC Hip04. - -+config MTD_NAND_QCOM -+ tristate "Support for NAND on QCOM SoCs" -+ depends on ARCH_QCOM -+ help -+ Enables support for NAND flash chips on SoCs containing the EBI2 NAND -+ controller.
