-EFI on U-Boot
-=============
-This document provides information about the implementation of the UEFI API [1]
-in U-Boot.
-
-
-=========== Table of Contents ===========
-
-Motivation
-How do I get it?
-Status
-Future work
-
-
-Motivation
-----------
-
-With this API support in place, you can run any UEFI payload (such as the Linux
-kernel, grub2 or gummiboot) on U-Boot. This dramatically simplifies boot loader
-configuration, as U-Boot based systems now look and feel (almost) the same way
-as TianoCore based systems.
-
-How do I get it?
-----------------
-
-EFI support for 32bit ARM and AArch64 is already included in U-Boot. All you
-need to do is enable
-
- CONFIG_CMD_BOOTEFI=y
- CONFIG_EFI_LOADER=y
-
-in your .config file and you will automatically get a bootefi command to run
-an efi application as well as snippet in the default distro boot script that
-scans for removable media efi binaries as fallback.
-
-Status
-------
-
-I am successfully able to run grub2 and Linux EFI binaries with this code on
-ARMv7 as well as AArch64 systems.
-
-When enabled, the resulting U-Boot binary only grows by ~10KB, so it's very
-light weight.
-
-All storage devices are directly accessible from the uEFI payload
-
-Removable media booting (search for /efi/boot/boota{a64,arm}.efi) is supported.
-
-Simple use cases like "Plug this SD card into my ARM device and it just
-boots into grub which boots into Linux", work very well.
-
-
-Running HelloWord.efi
----------------------
-
-You can run a simple 'hello world' EFI program in U-Boot.
-Enable the option CONFIG_CMD_BOOTEFI_HELLO.
-
-Then you can boot into U-Boot and type:
-
- > bootefi hello
-
-The 'hello world EFI' program will then run, print a message and exit.
-
-
-Future work
------------
-
-Of course, there are still a few things one could do on top:
-
- - Improve disk media detection (don't scan, use what information we
-have)
- - Add EFI variable support using NVRAM
- - Add GFX support
- - Make EFI Shell work
- - Network device support
- - Support for payload exit
- - Payload Watchdog support

+# UEFI on U-Boot
+
+The Unified Extensible Firmware Interface Specification (UEFI) [1] has become
+the default for booting on AArch64 and x86 systems. It provides a stable API for
+the interaction of drivers and applications with the firmware. The API comprises
+access to block storage, network, and console to name a few. The Linux kernel
+and boot loaders like GRUB or the FreeBSD loader can be executed.
+
+## Building for UEFI
+
+The UEFI standard supports only little endian systems. The UEFI support can be
+activated for ARM and x86 by specifying
+
+ CONFIG_CMD_BOOTEFI=y
+ CONFIG_EFI_LOADER=y
+
+in the .config file.
+
+Support for attaching virtual block devices, e.g. iSCSI drives connected by the
+loaded UEFI application [3], requires
+
+ CONFIG_BLK=y
+ CONFIG_PARTITIONS=y
+
+### Executing a UEFI binary
+
+The bootefi command is used to start UEFI applications or to install UEFI
+drivers. It takes two parameters
+
+ bootefi <image address> [fdt address]
+
+* image address - the memory address of the UEFI binary
+* fdt address - the memory address of the flattened device tree
+
+Below you find the output of an example session starting GRUB.
+
+ => load mmc 0:2 ${fdt_addr_r} boot/dtb
+ 29830 bytes read in 14 ms (2 MiB/s)
+ => load mmc 0:1 ${kernel_addr_r} efi/debian/grubaa64.efi
+ reading efi/debian/grubaa64.efi
+ 120832 bytes read in 7 ms (16.5 MiB/s)
+ => bootefi ${kernel_addr_r} ${fdt_addr_r}
+
+The environment variable 'bootargs' is passed as load options in the UEFI system
+table. The Linux kernel EFI stub uses the load options as command line
+arguments.
+
+### Executing the boot manager
+
+The UEFI specfication foresees to define boot entries and boot sequence via UEFI
+variables. Booting according to these variables is possible via
+
+ bootefi bootmgr [fdt address]
+
+As of U-Boot v2018.03 UEFI variables are not persisted and cannot be set at
+runtime.
+
+### Executing the built in hello world application
+
+A hello world UEFI application can be built with
+
+ CONFIG_CMD_BOOTEFI_HELLO_COMPILE=y
+
+It can be embedded into the U-Boot binary with
+
+ CONFIG_CMD_BOOTEFI_HELLO=y
+
+The bootefi command is used to start the embedded hello world application.
+
+ bootefi hello [fdt address]
+
+Below you find the output of an example session.
+
+ => bootefi hello ${fdtcontroladdr}
+ ## Starting EFI application at 01000000 ...
+ WARNING: using memory device/image path, this may confuse some payloads!
+ Hello, world!
+ Running on UEFI 2.7
+ Have SMBIOS table
+ Have device tree
+ Load options: root=/dev/sdb3 init=/sbin/init rootwait ro
+ ## Application terminated, r = 0
+
+The environment variable fdtcontroladdr points to U-Boot's internal device tree
+(if available).
+
+### Executing the built-in selftest
+
+An UEFI selftest suite can be embedded in U-Boot by building with
+
+ CONFIG_CMD_BOOTEFI_SELFTEST=y
+
+For testing the UEFI implementation the bootefi command can be used to start the
+selftest.
+
+ bootefi selftest [fdt address]
+
+The environment variable 'efi_selftest' can be used to select a single test. If
+it is not provided all tests are executed except those marked as 'on request'.
+If the environment variable is set to 'list' a list of all tests is shown.
+
+Below you can find the output of an example session.
+
+ => setenv efi_selftest simple network protocol
+ => bootefi selftest
+ Testing EFI API implementation
+ Selected test: 'simple network protocol'
+ Setting up 'simple network protocol'
+ Setting up 'simple network protocol' succeeded
+ Executing 'simple network protocol'
+ DHCP Discover
+ DHCP reply received from 192.168.76.2 (52:55:c0:a8:4c:02)
+ as broadcast message.
+ Executing 'simple network protocol' succeeded
+ Tearing down 'simple network protocol'
+ Tearing down 'simple network protocol' succeeded
+ Boot services terminated
+ Summary: 0 failures
+ Preparing for reset. Press any key.
+
+## The UEFI life cycle
+
+After the U-Boot platform has been initialized the UEFI API provides two kinds
+of services
+
+* boot services and
+* runtime services.
+
+The API can be extended by loading UEFI drivers which come in two variants
+
+* boot drivers and
+* runtime drivers.
+
+UEFI drivers are installed with U-Boot's bootefi command. With the same command
+UEFI applications can be executed.
+
+Loaded images of UEFI drivers stay in memory after returning to U-Boot while
+loaded images of applications are removed from memory.
+
+An UEFI application (e.g. an operating system) that wants to take full control
+of the system calls ExitBootServices. After a UEFI application calls
+ExitBootServices
+
+* boot services are not available anymore
+* timer events are stopped
+* the memory used by U-Boot except for runtime services is released
+* the memory used by boot time drivers is released
+
+So this is a point of no return. Afterwards the UEFI application can only return
+to U-Boot by rebooting.
+
+## The UEFI object model
+
+UEFI offers a flexible and expandable object model. The objects in the UEFI API
+are devices, drivers, and loaded images. These objects are referenced by
+handles.
+
+The interfaces implemented by the objects are referred to as protocols. These
+are identified by GUIDs. They can be installed and uninstalled by calling the
+appropriate boot services.
+
+Handles are created by the InstallProtocolInterface or the
+InstallMultipleProtocolinterfaces service if NULL is passed as handle.
+
+Handles are deleted when the last protocol has been removed with the
+UninstallProtocolInterface or the UninstallMultipleProtocolInterfaces service.
+
+Devices offer the EFI_DEVICE_PATH_PROTOCOL. A device path is the concatenation
+of device nodes. By their device paths all devices of a system are arranged in a
+tree.
+
+Drivers offer the EFI_DRIVER_BINDING_PROTOCOL. This protocol is used to connect
+a driver to devices (which are referenced as controllers in this context).
+
+Loaded images offer the EFI_LOADED_IMAGE_PROTOCOL. This protocol provides meta
+information about the image and a pointer to the unload callback function.
+
+## The UEFI events
+
+In the UEFI terminology an event is a data object referencing a notification
+function which is queued for calling when the event is signaled. The following
+types of events exist:
+
+* periodic and single shot timer events
+* exit boot services events, triggered by calling the ExitBootServices() service
+* virtual address change events
+* memory map change events
+* read to boot events
+* reset system events
+* system table events
+* events that are only triggered programmatically
+
+Events can be created with the CreateEvent service and deleted with CloseEvent
+service.
+
+Events can be assigned to an event group. If any of the events in a group is
+signaled, all other events in the group are also set to the signaled state.
+
+## The UEFI driver model
+
+A driver is specific for a single protocol installed on a device. To install a
+driver on a device the ConnectController service is called. In this context
+controller refers to the device for which the driver is installed.
+
+The relevant drivers are identified using the EFI_DRIVER_BINDING_PROTOCOL. This
+protocol has has three functions:
+
+* supported - determines if the driver is compatible with the device
+* start - installs the driver by opening the relevant protocol with
+ attribute EFI_OPEN_PROTOCOL_BY_DRIVER
+* stop - uninstalls the driver
+
+The driver may create child controllers (child devices). E.g. a driver for block
+IO devices will create the device handles for the partitions. The child
+controllers will open the supported protocol with the attribute
+EFI_OPEN_PROTOCOL_BY_CHILD_CONTROLLER.
+
+A driver can be detached from a device using the DisconnectController service.
+
+## U-Boot devices mapped as UEFI devices
+
+Some of the U-Boot devices are mapped as UEFI devices
+
+* block IO devices
+* console
+* graphical output
+* network adapter
+
+As of U-Boot 2018.03 the logic for doing this is hard coded.
+
+The development target is to integrate the setup of these UEFI devices with the
+U-Boot driver model. So when a U-Boot device is discovered a handle should be
+created and the device path protocol and the relevant IO protocol should be
+installed. The UEFI driver then would be attached by calling ConnectController.
+When a U-Boot device is removed DisconnectController should be called.
+
+## UEFI devices mapped as U-Boot devices
+
+UEFI drivers binaries and applications may create new (virtual) devices, install
+a protocol and call the ConnectController service. Now the matching UEFI driver
+is determined by iterating over the implementations of the
+EFI_DRIVER_BINDING_PROTOCOL.
+
+It is the task of the UEFI driver to create a corresponding U-Boot device and to
+proxy calls for this U-Boot device to the controller.
+
+In U-Boot 2018.03 this has only been implemented for block IO devices.
+
+### UEFI uclass
+
+An UEFI uclass driver (lib/efi_driver/efi_uclass.c) has been created that
+takes care of initializing the UEFI drivers and providing the
+EFI_DRIVER_BINDING_PROTOCOL implementation for the UEFI drivers.
+
+A linker created list is used to keep track of the UEFI drivers. To create an
+entry in the list the UEFI driver uses the U_BOOT_DRIVER macro specifying
+UCLASS_EFI as the ID of its uclass, e.g.
+
+ /* Identify as UEFI driver */
+ U_BOOT_DRIVER(efi_block) = {
+ .name = "EFI block driver",
+ .id = UCLASS_EFI,
+ .ops = &driver_ops,
+ };
+
+The available operations are defined via the structure struct efi_driver_ops.
+
+ struct efi_driver_ops {
+ const efi_guid_t *protocol;
+ const efi_guid_t *child_protocol;
+ int (*bind)(efi_handle_t handle, void *interface);
+ };
+
+When the supported() function of the EFI_DRIVER_BINDING_PROTOCOL is called the
+uclass checks if the protocol GUID matches the protocol GUID of the UEFI driver.
+In the start() function the bind() function of the UEFI driver is called after
+checking the GUID.
+The stop() function of the EFI_DRIVER_BINDING_PROTOCOL disconnects the child
+controllers created by the UEFI driver and the UEFI driver. (In U-Boot v2013.03
+this is not yet completely implemented.)
+
+### UEFI block IO driver
+
+The UEFI block IO driver supports devices exposing the EFI_BLOCK_IO_PROTOCOL.
+
+When connected it creates a new U-Boot block IO device with interface type
+IF_TYPE_EFI, adds child controllers mapping the partitions, and installs the
+EFI_SIMPLE_FILE_SYSTEM_PROTOCOL on these. This can be used together with the
+software iPXE to boot from iSCSI network drives [3].
+
+This driver is only available if U-Boot is configured with
+
+ CONFIG_BLK=y
+ CONFIG_PARTITIONS=y
+
+## TODOs as of U-Boot 2018.03
