+Summary
+=======
+
+This document covers the PDU001 target.
+
+Hardware
+========
+
+The PDU-001 (Processor and Display Unit) is a plugin card for 19" racks. It is
+manufactured by EETS GmbH (https://www.eets.ch). The core of the board is a m2
+SOM from bytes at work (https://www.bytesatwork.ch) which in turn is based on
+AM3352 SOC from TI (http://www.ti.com).
+
+Customization
+=============
+
+As usual the console serial interface is set by CONFIG_CONS_INDEX. Best choice
+is 4 here since UART3 is wired to the connector K2.
+The Run LED on the PDU-001 can be turned on red by setting CONFIG_RUN_LED_RED
+or green by setting CONFIG_RUN_LED_GREEN. Setting CONFIG_RUN_LED_OFF will turn
+off the Run LED.
+
+Booting
+=======
+
+The system boots from either eMMC or SD card cage. It will first try to boot
+from the SD card cage. If this fails (missing or unbootable SD card) it will
+try to boot from the internal eMMC. The root file system is always expected to
+be located in the second partition of the device (eMMC or SD card) that pro-
+vided the boot loader.

- This driver supports the built-in GPIO controller of MPC85XX CPUs.
+ This driver supports the built-in GPIO controller of MPC8XXX CPUs.
Each GPIO bank is identified by its own entry in the device tree,
i.e.
Aside from the standard functions of input/output mode, and output
value setting, the open-drain feature, which can configure individual
GPIOs to work as open-drain outputs, is supported.
-
- The driver has been tested on MPC85XX, but it is likely that other
- PowerQUICC III devices will work as well.

+ * bcm2835 sdhost driver.
+ *
+ * The 2835 has two SD controllers: The Arasan sdhci controller
+ * (supported by the iproc driver) and a custom sdhost controller
+ * (supported by this driver).
+ *
+ * The sdhci controller supports both sdcard and sdio. The sdhost
+ * controller supports the sdcard only, but has better performance.
+ * Also note that the rpi3 has sdio wifi, so driving the sdcard with
+ * the sdhost controller allows to use the sdhci controller for wifi
+ * support.
+ *
+ * The configuration is done by devicetree via pin muxing. Both
+ * SD controller are available on the same pins (2 pin groups = pin 22
+ * to 27 + pin 48 to 53). So it's possible to use both SD controllers
+ * at the same time with different pin groups.
+ *
+ * This code was ported to U-Boot by
+ * Alexander Graf <agraf@suse.de>
+ * and is based on drivers/mmc/host/bcm2835.c in Linux which is written by
+ * Phil Elwell <phil@raspberrypi.org>

+/**
+ * fdt_first_region() - find regions in device tree
+ *
+ * Given a nodes and properties to include and properties to exclude, find
+ * the regions of the device tree which describe those included parts.
+ *
+ * The use for this function is twofold. Firstly it provides a convenient
+ * way of performing a structure-aware grep of the tree. For example it is
+ * possible to grep for a node and get all the properties associated with
+ * that node. Trees can be subsetted easily, by specifying the nodes that
+ * are required, and then writing out the regions returned by this function.
+ * This is useful for small resource-constrained systems, such as boot
+ * loaders, which want to use an FDT but do not need to know about all of
+ * it.
+ *
+ * Secondly it makes it easy to hash parts of the tree and detect changes.
+ * The intent is to get a list of regions which will be invariant provided
+ * those parts are invariant. For example, if you request a list of regions
+ * for all nodes but exclude the property "data", then you will get the
+ * same region contents regardless of any change to "data" properties.
+ *
+ * This function can be used to produce a byte-stream to send to a hashing
+ * function to verify that critical parts of the FDT have not changed.
+ * Note that semantically null changes in order could still cause false
+ * hash misses. Such reordering might happen if the tree is regenerated
+ * from source, and nodes are reordered (the bytes-stream will be emitted
+ * in a different order and many hash functions will detect this). However
+ * if an existing tree is modified using libfdt functions, such as
+ * fdt_add_subnode() and fdt_setprop(), then this problem is avoided.
+ *
+ * The nodes/properties to include/exclude are defined by a function
+ * provided by the caller. This function is called for each node and
+ * property, and must return:
+ *
+ * 0 - to exclude this part
+ * 1 - to include this part
+ * -1 - for FDT_IS_PROP only: no information is available, so include
+ * if its containing node is included
+ *
+ * The last case is only used to deal with properties. Often a property is
+ * included if its containing node is included - this is the case where
+ * -1 is returned.. However if the property is specifically required to be
+ * included/excluded, then 0 or 1 can be returned. Note that including a
+ * property when the FDT_REG_SUPERNODES flag is given will force its
+ * containing node to be included since it is not valid to have a property
+ * that is not in a node.
+ *
+ * Using the information provided, the inclusion of a node can be controlled
+ * either by a node name or its compatible string, or any other property
+ * that the function can determine.
+ *
+ * As an example, including node "/" means to include the root node and all
+ * root properties. A flag provides a way of also including supernodes (of
+ * which there is none for the root node), and another flag includes
+ * immediate subnodes, so in this case we would get the FDT_BEGIN_NODE and
+ * FDT_END_NODE of all subnodes of /.
+ *
+ * The subnode feature helps in a hashing situation since it prevents the
+ * root node from changing at all. Any change to non-excluded properties,
+ * names of subnodes or number of subnodes would be detected.
+ *
+ * When used with FITs this provides the ability to hash and sign parts of
+ * the FIT based on different configurations in the FIT. Then it is
+ * impossible to change anything about that configuration (include images
+ * attached to the configuration), but it may be possible to add new
+ * configurations, new images or new signatures within the existing
+ * framework.
+ *
+ * Adding new properties to a device tree may result in the string table
+ * being extended (if the new property names are different from those
+ * already added). This function can optionally include a region for
+ * the string table so that this can be part of the hash too. This is always
+ * the last region.
+ *
+ * The FDT also has a mem_rsvmap table which can also be included, and is
+ * always the first region if so.
+ *
+ * The device tree header is not included in the region list. Since the
+ * contents of the FDT are changing (shrinking, often), the caller will need
+ * to regenerate the header anyway.

+ * available
+ * @priv: Private pointer passed to h_include

-/**
- * fdt_first_region() - find regions in device tree
- *
- * Given a nodes and properties to include and properties to exclude, find
- * the regions of the device tree which describe those included parts.
- *
- * The use for this function is twofold. Firstly it provides a convenient
- * way of performing a structure-aware grep of the tree. For example it is
- * possible to grep for a node and get all the properties associated with
- * that node. Trees can be subsetted easily, by specifying the nodes that
- * are required, and then writing out the regions returned by this function.
- * This is useful for small resource-constrained systems, such as boot
- * loaders, which want to use an FDT but do not need to know about all of
- * it.
- *
- * Secondly it makes it easy to hash parts of the tree and detect changes.
- * The intent is to get a list of regions which will be invariant provided
- * those parts are invariant. For example, if you request a list of regions
- * for all nodes but exclude the property "data", then you will get the
- * same region contents regardless of any change to "data" properties.
- *
- * This function can be used to produce a byte-stream to send to a hashing
- * function to verify that critical parts of the FDT have not changed.
- * Note that semantically null changes in order could still cause false
- * hash misses. Such reordering might happen if the tree is regenerated
- * from source, and nodes are reordered (the bytes-stream will be emitted
- * in a different order and mnay hash functions will detect this). However
- * if an existing tree is modified using libfdt functions, such as
- * fdt_add_subnode() and fdt_setprop(), then this problem is avoided.
- *
- * The nodes/properties to include/exclude are defined by a function
- * provided by the caller. This function is called for each node and
- * property, and must return:
- *
- * 0 - to exclude this part
- * 1 - to include this part
- * -1 - for FDT_IS_PROP only: no information is available, so include
- * if its containing node is included
- *
- * The last case is only used to deal with properties. Often a property is
- * included if its containing node is included - this is the case where
- * -1 is returned.. However if the property is specifically required to be
- * included/excluded, then 0 or 1 can be returned. Note that including a
- * property when the FDT_REG_SUPERNODES flag is given will force its
- * containing node to be included since it is not valid to have a property
- * that is not in a node.
- *
- * Using the information provided, the inclusion of a node can be controlled
- * either by a node name or its compatible string, or any other property
- * that the function can determine.
- *
- * As an example, including node "/" means to include the root node and all
- * root properties. A flag provides a way of also including supernodes (of
- * which there is none for the root node), and another flag includes
- * immediate subnodes, so in this case we would get the FDT_BEGIN_NODE and
- * FDT_END_NODE of all subnodes of /.
- *
- * The subnode feature helps in a hashing situation since it prevents the
- * root node from changing at all. Any change to non-excluded properties,
- * names of subnodes or number of subnodes would be detected.
- *
- * When used with FITs this provides the ability to hash and sign parts of
- * the FIT based on different configurations in the FIT. Then it is
- * impossible to change anything about that configuration (include images
- * attached to the configuration), but it may be possible to add new
- * configurations, new images or new signatures within the existing
- * framework.
- *
- * Adding new properties to a device tree may result in the string table
- * being extended (if the new property names are different from those
- * already added). This function can optionally include a region for
- * the string table so that this can be part of the hash too. This is always
- * the last region.
- *
- * The FDT also has a mem_rsvmap table which can also be included, and is
- * always the first region if so.
- *
- * The device tree header is not included in the region list. Since the
- * contents of the FDT are changing (shrinking, often), the caller will need
- * to regenerate the header anyway.
