ipq806x: Add support for linux-4.4
1)Changes
- Rebased the patches for linux-4.4.7
- Added patch to fix spi nor fifo and dma support
- Added patch to configure watchdog barktime
2)Testing
Tested on IPQ AP148 Board:
a. NOR boot and NAND boot
b. ethernet network and ath10k wifi
c. ubi sysupgrade
UnTested
dwc3 usb has not been validated on IPQ board(AP148)
3)Known Issues:
Once we flash ubi image on AP148, and if we reset the board, uboot on
first boot creates PEB and LEB for dynamic sized partitions, which is incorrect
and not what linux expects which causes errors when trying to mount rootfs.
In order to test this, we can use the below steps:
a. Flash the ubi image on board and don't reset the board
b. load the kernel fit image in RAM and boot from there.

Errors -manifested themselves as input underruns, output overruns, and timed out -transactions. - -The block mode does not require the priming that occurs in FIFO mode. At the -moment that the QUP is placed into the RUN state, the QUP will immediately raise -an interrupt if the request is a write. Therefore, there is no need to prime -the pump. - -In addition, the block transfers require that whole blocks of data are -read/written at a time. The last block of data that completes a transaction may -contain less than a full blocks worth of data. - -Each block of data results in an input/output service interrupt accompanied with -a input/output block flag set. Additional block reads/writes require clearing -of the service flag. It is ok to check for additional blocks of data in the -ISR, but you have to ack every block you transfer. Imbalanced acks result in -early return from complete transactions with pending interrupts that still have -to be ack'd. The next transaction can be affected by these interrupts. -Transactions are deemed complete when the MAX_INPUT or MAX_OUTPUT flag are set. - -Changes from v2: -- Added in additional completion check so that transaction done is not - prematurely signaled. -- Fixed various review comments. - -Changes from v1: -- Split out read/write block function. -- Removed extraneous checks for transfer length - -Signed-off-by: Andy Gross <agross@codeaurora.org> - ---- -drivers/spi/spi-qup.c | 201 ++++++++++++++++++++++++++++++++++++------------- - 1 file changed, 148 insertions(+), 53 deletions(-) - ---- a/drivers/spi/spi-qup.c -+++ b/drivers/spi/spi-qup.c -@@ -82,6 +82,8 @@ - #define QUP_IO_M_MODE_BAM 3 - - /* QUP_OPERATIONAL fields */ -+#define QUP_OP_IN_BLOCK_READ_REQ BIT(13) -+#define QUP_OP_OUT_BLOCK_WRITE_REQ BIT(12) - #define QUP_OP_MAX_INPUT_DONE_FLAG BIT(11) - #define QUP_OP_MAX_OUTPUT_DONE_FLAG BIT(10) - #define QUP_OP_IN_SERVICE_FLAG BIT(9) -@@ -147,6 +149,7 @@ struct spi_qup { - int tx_bytes;

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 -@@ -516,4 +516,11 @@ config MTD_NAND_XWAY - Enables support for NAND Flash chips on Lantiq XWAY SoCs.

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-4.1/700-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 deleted file mode 100644 index dfe7169..0000000 --- a/target/linux/ipq806x/patches-4.1/700-clk-qcom-Add-support-for-NSS-GMAC-clocks-and-resets.patch +++ /dev/null @@ -1,734 +0,0 @@ -From 2fbb18f85826a9ba308fedb2cf90d3a661a39fd7 Mon Sep 17 00:00:00 2001 -From: Stephen Boyd <sboyd@codeaurora.org> -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 <sboyd@codeaurora.org> ---- - 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 = { - }, - };
