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 <agross@codeaurora.org> -Signed-off-by: Archit Taneja <architt@codeaurora.org> - ---- -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 -@@ -530,4 +530,11 @@ 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.

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 -@@ -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 -@@ -248,9 +248,11 @@ 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 $(plat-y))) ---- /dev/null -+++ b/arch/arm/mach-qcom/Makefile.boot -@@ -0,0 +1 @@ -+zreladdr-y+= 0x42208000 diff --git a/target/linux/ipq806x/patches-4.1/301-ARM-qcom-add-Netgear-Nighthawk-X4-R7500-device-tree.patch b/target/linux/ipq806x/patches-4.1/301-ARM-qcom-add-Netgear-Nighthawk-X4-R7500-device-tree.patch deleted file mode 100644 index 1f5eba8377..0000000000 --- a/target/linux/ipq806x/patches-4.1/301-ARM-qcom-add-Netgear-Nighthawk-X4-R7500-device-tree.patch +++ /dev/null @@ -1,367 +0,0 @@ -From 7e77aa188a7a7c4391856a9e5ef5ef58f769e679 Mon Sep 17 00:00:00 2001 -From: Jonas Gorski <jogo@openwrt.org> -Date: Sun, 9 Aug 2015 13:02:38 +0200 -Subject: [PATCH] ARM: qcom: add Netgear Nighthawk X4 R7500 device tree - -Signed-off-by: Jonas Gorski <jogo@openwrt.org> ---- - arch/arm/boot/dts/Makefile | 1 + - arch/arm/boot/dts/qcom-ipq8064-r7500.dts | 370 +++++++++++++++++++++++++++++++ - 2 files changed, 371 insertions(+) - create mode 100644 arch/arm/boot/dts/qcom-ipq8064-r7500.dts - ---- a/arch/arm/boot/dts/Makefile -+++ b/arch/arm/boot/dts/Makefile -@@ -452,6 +452,7 @@ dtb-$(CONFIG_ARCH_QCOM) += \ - qcom-apq8084-mtp.dtb \ - qcom-ipq8064-ap148.dtb \ - qcom-ipq8064-db149.dtb \ -+ qcom-ipq8064-r7500.dtb \ - qcom-msm8660-surf.dtb \ - qcom-msm8960-cdp.dtb \ - qcom-msm8974-sony-xperia-honami.dtb ---- /dev/null -+++ b/arch/arm/boot/dts/qcom-ipq8064-r7500.dts -@@ -0,0 +1,342 @@ -+#include "qcom-ipq8064-v1.0.dtsi" -+ -+#include <dt-bindings/input/input.h> -+ -+/ { -+ model = "Netgear Nighthawk X4 R7500"; -+ compatible = "netgear,r7500", "qcom,ipq8064"; -+ -+ memory@0 { -+ reg = <0x42000000 0xe000000>; -+ device_type = "memory"; -+ }; -+ -+ reserved-memory { -+ #address-cells = <1>; -+ #size-cells = <1>; -+ ranges; -+ rsvd@41200000 { -+ reg = <0x41200000 0x300000>; -+ no-map; -+ }; -+ }; -+ -+ aliases { -+ serial0 = &uart4; -+ mdio-gpio0 = &mdio0; -+ }; -+ -+ chosen { -+ bootargs = "rootfstype=squashfs noinitrd"; -+ linux,stdout-path = "serial0:115200n8"; -+ }; -+ -+ soc { -+ pinmux@800000 { -+ i2c4_pins: i2c4_pinmux { -+ pins = "gpio12", "gpio13"; -+ function = "gsbi4"; -+ bias-disable; -+ }; -+ -+ nand_pins: nand_pins { -+ mux { -+ pins = "gpio34", "gpio35", "gpio36", -+ "gpio37", "gpio38", "gpio39", -+ "gpio40", "gpio41", "gpio42", -+ "gpio43", "gpio44", "gpio45", -+ "gpio46", "gpio47"; -+ function = "nand"; -+ drive-strength = <10>; -+ bias-disable; -+ }; -+ pullups { -+ pins = "gpio39"; -+ bias-pull-up; -+ }; -+ hold { -+ pins = "gpio40", "gpio41", "gpio42", -+ "gpio43", "gpio44", "gpio45", -+ "gpio46", "gpio47"; -+ bias-bus-hold; -+ }; -+ }; -+ -+ mdio0_pins: mdio0_pins { -+ mux { -+ pins = "gpio0", "gpio1"; -+ function = "gpio"; -+ drive-strength = <8>; -+ bias-disable; -+ }; -+ }; -+ -+ rgmii2_pins: rgmii2_pins { -+ mux { -+ pins = "gpio27", "gpio28", "gpio29", "gpio30", "gpio31", "gpio32", -+ "gpio51", "gpio52", "gpio59", "gpio60", "gpio61", "gpio62" ; -+ function = "rgmii2"; -+ drive-strength = <8>; -+ bias-disable; -+ }; -+ }; -+ }; -+ -+ gsbi@16300000 { -+ qcom,mode = <GSBI_PROT_I2C_UART>; -+ status = "ok"; -+ serial@16340000 { -+ status = "ok"; -+ }; -+ /* -+ * The i2c device on gsbi4 should not be enabled. -+ * On ipq806x designs gsbi4 i2c is meant for exclusive -+ * RPM usage.
