CONFIG_CMD_SAVEENV saveenv
- CONFIG_CMD_FAT * FAT command support
CONFIG_CMD_FLASH flinfo, erase, protect
CONFIG_CMD_FPGA FPGA device initialization support
CONFIG_CMD_GO * the 'go' command (exec code)
- Partition Labels (disklabels) Supported:
Zero or more of the following:
CONFIG_MAC_PARTITION Apple's MacOS partition table.
- CONFIG_DOS_PARTITION MS Dos partition table, traditional on the
- Intel architecture, USB sticks, etc.
CONFIG_ISO_PARTITION ISO partition table, used on CDROM etc.
CONFIG_EFI_PARTITION GPT partition table, common when EFI is the
bootloader. Note 2TB partition limit; see
CONFIG_SYS_JFFS2_FIRST_BANK, CONFIG_SYS_JFFS2_NUM_BANKS
Define these for a default partition on a NOR device
-- FAT(File Allocation Table) filesystem write function support:
- CONFIG_FAT_WRITE
-
- Define this to enable support for saving memory data as a
- file in FAT formatted partition.
-
- This will also enable the command "fatwrite" enabling the
- user to write files to FAT.
-
-- FAT(File Allocation Table) filesystem cluster size:
- CONFIG_FS_FAT_MAX_CLUSTSIZE
-
- Define the max cluster size for fat operations else
- a default value of 65536 will be defined.

Compile ARM Trusted Firmware (ATF)
==================================
- > cd ~/hikey/src/atf
+ > cd ~/hikey/src/arm-trusted-firmware
> make CROSS_COMPILE=aarch64-linux-gnu- all fip \
BL30=~/hikey/bin/mcuimage.bin \
BL33=~/hikey/bin/u-boot.bin DEBUG=1 PLAT=hikey
Compile l-loader
===============
- > cd ~/hikey/l-loader
+ > cd ~/hikey/src/l-loader
> make BL1=~/hikey/bin/bl1.bin all
> cp *.img ~/hikey/bin
- > cp l-loader.bin ~/hikey.bin
+ > cp l-loader.bin ~/hikey/bin
These instructions are adapted from
https://github.com/96boards/documentation/wiki/HiKeyUEFI
the hisi-idt.py utility.
The command below assumes HiKey enumerated as the first USB serial port
- > sudo ~/hikey/burn_boot/hisi-idt.py -d /dev/ttyUSB0 --img1=~/hikey/bin/l-loader.bin
+ > sudo ~/hikey/src/burn-boot/hisi-idt.py -d /dev/ttyUSB0 --img1=~/hikey/bin/l-loader.bin
2. Once LED 0 comes on solid, HiKey board should be detected as a fastboot device by plugging a USB A to mini B
cable from your PC to the USB OTG port of HiKey (on some boards I've found this to be unreliable).

-/**
- * 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.

+/**
+ * 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.
