+Overview
+--------
+QorIQ LS1012A Reference Design System (LS1012ARDB) is a high-performance
+development platform, with a complete debugging environment.
+The LS1012ARDB board supports the QorIQ LS1012A processor and is
+optimized to support the high-bandwidth DDR3L memory and
+a full complement of high-speed SerDes ports.
+
+LS1012A SoC Overview
+--------------------
+Please refer arch/arm/cpu/armv8/fsl-layerscape/doc/README.soc for LS2080A
+SoC overview.
+
+LS1012ARDB board Overview
+-----------------------
+ - SERDES Connections, 4 lanes supporting:
+      - PCI Express - 3.0
+      - SGMII, SGMII 2.5
+      - SATA 3.0
+ - DDR Controller
+     - 16-bit, 1 GB DDR3L SDRAM memory, running at data rates up to 1 GT/s
+ -QSPI: A dual 1:3 switch, NX3L4357GM,115 (U35) drives the QSPI chip-select
+ signals to
+    - QSPI NOR flash memory (2 virtual banks)
+    - the QSPI emulator.s
+ - USB 3.0
+    - one high-speed USB 2.0/3.0 port.
+ - Two enhanced secure digital host controllers:
+    - SDHC1 controller can be connected to onboard SDHC connector
+    - SDHC2 controller: Three dual 1:4 mux/demux devices,
+    74CBTLV3253DS (U30, U31, U33) drive the SDHC2 signals to eMMC,
+    SDIO WiFi, SPI, and Ardiuno shield
+ - 2 I2C controllers
+ - One SATA onboard connectors
+ - UART
+   - The LS1012A processor consists of two UART controllers,
+   out of which only UART1 is used on RDB.
+ - ARM JTAG support

+NVIDIA Tegra186 GPIO controllers
+
+Tegra186 contains two GPIO controllers; a main controller and an "AON"
+controller. This binding document applies to both controllers. The register
+layouts for the controllers share many similarities, but also some significant
+differences. Hence, this document describes closely related but different
+bindings and compatible values.
+
+The Tegra186 GPIO controller allows software to set the IO direction of, and
+read/write the value of, numerous GPIO signals. Routing of GPIO signals to
+package balls is under the control of a separate pin controller HW block. Two
+major sets of registers exist:
+
+a) Security registers, which allow configuration of allowed access to the GPIO
+register set. These registers exist in a single contiguous block of physical
+address space. The size of this block, and the security features available,
+varies between the different GPIO controllers.
+
+Access to this set of registers is not necessary in all circumstances. Code
+that wishes to configure access to the GPIO registers needs access to these
+registers to do so. Code which simply wishes to read or write GPIO data does not
+need access to these registers.
+
+b) GPIO registers, which allow manipulation of the GPIO signals. In some GPIO
+controllers, these registers are exposed via multiple "physical aliases" in
+address space, each of which access the same underlying state. See the hardware
+documentation for rationale. Any particular GPIO client is expected to access
+just one of these physical aliases.
+
+Tegra HW documentation describes a unified naming convention for all GPIOs
+implemented by the SoC. Each GPIO is assigned to a port, and a port may control
+a number of GPIOs. Thus, each GPIO is named according to an alphabetical port
+name and an integer GPIO name within the port. For example, GPIO_PA0, GPIO_PN6,
+or GPIO_PCC3.
+
+The number of ports implemented by each GPIO controller varies. The number of
+implemented GPIOs within each port varies. GPIO registers within a controller
+are grouped and laid out according to the port they affect.
+
+The mapping from port name to the GPIO controller that implements that port, and
+the mapping from port name to register offset within a controller, are both
+extremely non-linear. The header file <dt-bindings/gpio/tegra186-gpio.h>
+describes the port-level mapping. In that file, the naming convention for ports
+matches the HW documentation. The values chosen for the names are alphabetically
+sorted within a particular controller. Drivers need to map between the DT GPIO
+IDs and HW register offsets using a lookup table.
+
+Each GPIO controller can generate a number of interrupt signals. Each signal
+represents the aggregate status for all GPIOs within a set of ports. Thus, the
+number of interrupt signals generated by a controller varies as a rough function
+of the number of ports it implements. Note that the HW documentation refers to
+both the overall controller HW module and the sets-of-ports as "controllers".
+
+Each GPIO controller in fact generates multiple interrupts signals for each set
+of ports. Each GPIO may be configured to feed into a specific one of the
+interrupt signals generated by a set-of-ports. The intent is for each generated
+signal to be routed to a different CPU, thus allowing different CPUs to each
+handle subsets of the interrupts within a port. The status of each of these
+per-port-set signals is reported via a separate register. Thus, a driver needs
+to know which status register to observe. This binding currently defines no
+configuration mechanism for this. By default, drivers should use register
+GPIO_${port}_INTERRUPT_STATUS_G1_0. Future revisions to the binding could
+define a property to configure this.
+
+Required properties:
+- compatible
+    Array of strings.
+    One of:
+    - "nvidia,tegra186-gpio".
+    - "nvidia,tegra186-gpio-aon".
+- reg-names
+    Array of strings.
+    Contains a list of names for the register spaces described by the reg
+    property. May contain the following entries, in any order:
+    - "gpio": Mandatory. GPIO control registers. This may cover either:
+        a) The single physical alias that this OS should use.
+        b) All physical aliases that exist in the controller. This is
+           appropriate when the OS is responsible for managing assignment of
+           the physical aliases.
+    - "security": Optional. Security configuration registers.
+    Users of this binding MUST look up entries in the reg property by name,
+    using this reg-names property to do so.
+- reg
+    Array of (physical base address, length) tuples.
+    Must contain one entry per entry in the reg-names property, in a matching
+    order.
+- interrupts
+    Array of interrupt specifiers.
+    The interrupt outputs from the HW block, one per set of ports, in the
+    order the HW manual describes them. The number of entries required varies
+    depending on compatible value:
+    - "nvidia,tegra186-gpio": 6 entries.
+    - "nvidia,tegra186-gpio-aon": 1 entry.
+- gpio-controller
+    Boolean.
+    Marks the device node as a GPIO controller/provider.
+- #gpio-cells
+    Single-cell integer.
+    Must be <2>.
+    Indicates how many cells are used in a consumer's GPIO specifier.
+    In the specifier:
+    - The first cell is the pin number.
+        See <dt-bindings/gpio/tegra186-gpio.h>.
+    - The second cell contains flags:
+        - Bit 0 specifies polarity
+            - 0: Active-high (normal).
+            - 1: Active-low (inverted).
+- interrupt-controller
+    Boolean.
+    Marks the device node as an interrupt controller/provider.
+- #interrupt-cells
+    Single-cell integer.
+    Must be <2>.
+    Indicates how many cells are used in a consumer's interrupt specifier.
+    In the specifier:
+    - The first cell is the GPIO number.
+        See <dt-bindings/gpio/tegra186-gpio.h>.
+    - The second cell is contains flags:
+        - Bits [3:0] indicate trigger type and level:
+            - 1: Low-to-high edge triggered.
+            - 2: High-to-low edge triggered.
+            - 4: Active high level-sensitive.
+            - 8: Active low level-sensitive.
+            Valid combinations are 1, 2, 3, 4, 8.
+
+Example:
+
+#include <dt-bindings/interrupt-controller/irq.h>
+
+gpio@2200000 {
+	compatible = "nvidia,tegra186-gpio";
+	reg-names = "security", "gpio";

- * SPL driver for Diskonchip G4 nand flash
- *
- * Copyright (C) 2013 Mike Dunn <mikedunn@newsguy.com>
- *
- * SPDX-License-Identifier:	GPL-2.0+
- *
- * This driver basically mimics the load functionality of a typical IPL (initial
- * program loader) resident in the 2k NOR-like region of the docg4 that is
- * mapped to the reset vector.  It allows the u-boot SPL to continue loading if
- * the IPL loads a fixed number of flash blocks that is insufficient to contain
- * the entire u-boot image.  In this case, a concatenated spl + u-boot image is
- * written at the flash offset from which the IPL loads an image, and when the
- * IPL jumps to the SPL, the SPL resumes loading where the IPL left off.  See
- * the palmtreo680 for an example.
- *
- * This driver assumes that the data was written to the flash using the device's
- * "reliable" mode, and also assumes that each 512 byte page is stored
- * redundantly in the subsequent page.  This storage format is likely to be used
- * by all boards that boot from the docg4.  The format compensates for the lack
- * of ecc in the IPL.
- *
- * Reliable mode reduces the capacity of a block by half, and the redundant
- * pages reduce it by half again.  As a result, the normal 256k capacity of a
- * block is reduced to 64k for the purposes of the IPL/SPL.

+ * The bitflips_threshold specify the maximum number of bitflips before

+ *
+ * Note:
+ * 1/ ECC algorithms are working on pre-defined block sizes which are usually
+ *    different from the NAND page size. When fixing bitflips, ECC engines will
+ *    report the number of errors per chunk, and the NAND core infrastructure
+ *    expect you to return the maximum number of bitflips for the whole page.
+ *    This is why you should always use this function on a single chunk and
+ *    not on the whole page. After checking each chunk you should update your
+ *    max_bitflips value accordingly.
+ * 2/ When checking for bitflips in erased pages you should not only check
+ *    the payload data but also their associated ECC data, because a user might
+ *    have programmed almost all bits to 1 but a few. In this case, we
+ *    shouldn't consider the chunk as erased, and checking ECC bytes prevent
+ *    this case.
+ * 3/ The extraoob argument is optional, and should be used if some of your OOB
+ *    data are protected by the ECC engine.
+ *    It could also be used if you support subpages and want to attach some
+ *    extra OOB data to an ECC chunk.
+ *
+ * Returns a positive number of bitflips less than or equal to
+ * bitflips_threshold, or -ERROR_CODE for bitflips in excess of the

- * This is a userspace Linux utility that, when run on the Treo 680, will

- *        modprobe docg4 ignore_badblocks=1 reliable_mode=1
- *
- * This utility writes the concatenated spl + u-boot image to the start of the
- * mtd device in the format expected by the IPL/SPL.  The image file and mtd
- * device node are passed to the utility as arguments.  The blocks must have
- * been erased beforehand.
- *
- * When you compile this, note that it links to libmtd from mtd-utils, so ensure
- * that your include and lib paths include this.
