If 'bootefi hello' or 'bootefi selftest' can be executed depends on the configuration. If an invalid non-numeric 1st argument is passed to bootefi, e.g. 'bootefi hola', this string is converted to 0 and U-Boot jumps to this typically invalid address. With the patch the online help is shown instead. Signed-off-by: NHeinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: NAlexander Graf <agraf@suse.de>

EFI calls are usually defined as asmlinkage. That means we pass all parameters to functions via the stack x86_32. On x86_64 however, we need to also stick to the MS ABI calling conventions, which the EFIAPI define conveniently handles for us. Most EFI functions were also marked with EFIAPI, except for the entry call. So this patch adjusts all entry calls to use EFIAPI instead of the manual asmlinkage attribute. While at it, we also change the prototype of the entry point to return efi_status_t instead of ulong, as this is the correct prototype definition. Signed-off-by: NAlexander Graf <agraf@suse.de> --- v1 -> v2: - Use efi_status_t in all occurences

This patch provides * a uclass for EFI drivers * a EFI driver for block devices For each EFI driver the uclass * creates a handle * adds the driver binding protocol The uclass provides the bind, start, and stop entry points for the driver binding protocol. In bind() and stop() it checks if the controller implements the protocol supported by the EFI driver. In the start() function it calls the bind() function of the EFI driver. In the stop() function it destroys the child controllers. The EFI block driver binds to controllers implementing the block io protocol. When the bind function of the EFI block driver is called it creates a new U-Boot block device. It installs child handles for all partitions and installs the simple file protocol on these. The read and write functions of the EFI block driver delegate calls to the controller that it is bound to. A usage example is as following: U-Boot loads the iPXE snp.efi executable. iPXE connects an iSCSI drive and exposes a handle with the block IO protocol. It calls ConnectController. Now the EFI block driver installs the partitions with the simple file protocol. iPXE uses the simple file protocol to load Grub or the Linux Kernel.

When trying to load an image from a non-existent USB key, U-Boot v2017.11 crashes on my x86 platform: => load usb 0:1 03000000 abc General Protection EIP: 0010:[<7b59030d>] EFLAGS: 00010286 Original EIP :[<fff4330d>] ...

Environment variable efi_selftest is passed as load options to the selftest application. It is used to select a single test to be executed. The load options are an UTF8 string. Yet I decided to keep the name propertiy of the tests as char[] to reduce code size. Special value 'list' displays a list of all available tests. Tests get an on_request property. If this property is set the tests are only executed if explicitly requested. The invocation of efi_selftest is changed to reflect that bootefi selftest with efi_selftest = 'list' will call the Exit bootservice.

Similar to a "real" UEFI implementation, the bootmgr looks at the BootOrder and BootXXXX variables to try to find an EFI payload to load and boot. This is added as a sub-command of bootefi. The idea is that the distro bootcmd would first try loading a payload via the bootmgr, and then if that fails (ie. first boot or corrupted EFI variables) it would fallback to loading bootaa64.efi. (Which would then load fallback.efi which would look for \EFI\*\boot.csv and populate BootOrder and BootXXXX based on what it found.)

Add EFI variable support, mapping to u-boot environment variables. Variables are pretty important for setting up boot order, among other things. If the board supports saveenv, then it will be called in ExitBootServices() to persist variables set by the efi payload. (For example, fallback.efi configuring BootOrder and BootXXXX load-option variables.) Variables are *not* currently exposed at runtime, post ExitBootServices. On boards without a dedicated device for storage, which the loaded OS is not trying to also use, this is rather tricky. One idea, at least for boards that can persist RAM across reboot, is to keep a "journal" of modified variables in RAM, and then turn halt into a reboot into u-boot, plus store variables, plus halt. Whatever the solution, it likely involves some per-board support. Mapping between EFI variables and u-boot variables: efi_$guid_$varname = {attributes}(type)value For example: efi_8be4df61-93ca-11d2-aa0d-00e098032b8c_OsIndicationsSupported= "{ro,boot,run}(blob)0000000000000000" efi_8be4df61-93ca-11d2-aa0d-00e098032b8c_BootOrder= "(blob)00010000" The attributes are a comma separated list of these possible attributes: + ro - read-only + boot - boot-services access + run - runtime access NOTE: with current implementation, no variables are available after ExitBootServices, and all are persisted (if possible). If not specified, the attributes default to "{boot}". The required type is one of: + utf8 - raw utf8 string + blob - arbitrary length hex string Signed-off-by: NRob Clark <robdclark@gmail.com> Signed-off-by: NAlexander Graf <agraf@suse.de>

Get rid of the hacky fake boot-device and duplicate device-path constructing (which needs to match what efi_disk and efi_net do). Instead convert over to use efi_device_path helpers to construct device-paths, and use that to look up the actual boot device. Also, extract out a helper to plug things in properly to the loaded_image. In a following patch we'll want to re-use this in efi_load_image() to handle the case of loading an image from a file_path.

A testing framework for the EFI API is provided. It can be executed with the 'bootefi selftest' command. It is coded in a way that at a later stage we may turn it into a standalone EFI application. The current build system does not allow this yet. All tests use a driver model and are run in three phases: setup, execute, teardown. A test may be setup and executed at boottime, it may be setup at boottime and executed at runtime, or it may be setup and executed at runtime. After executing all tests the system is reset.

Command 'bootefi hello' currently uses CONFIG_SYS_LOAD_ADDR as loading address. qemu machines have by default 128 MiB RAM. CONFIG_SYS_LOAD_ADDR for x86 is 0x20000000 (512 MiB). This causes 'bootefi hello' to fail. We should use the environment variable loadaddr if available. It defaults to 0x1000000 (16 MiB) on qemu_x86.

Before commit 7cbc1241 ("efi_loader: initalize EFI object list only once") we recreated the world on every bootefi invocation. That included the object tree as well as the configuration tables. Now however we don't recreate them, which means we must not explicitly override the configuration tables, as otherwise we may lose our SMBIOS table from the configuration table list on second bootefi invocation. This patch makes bootefi call our normal configuration table modification APIs to add/remove the FDT instead of recreating all tables from scratch. That way the SMBIOS table gets preserved across multiple invocations. Signed-off-by: NAlexander Graf <agraf@suse.de>

The Unified Extensible Firmware Interface Specification, version 2.7, defines in chapter 2.1.2 - UEFI Application that an EFI application may either directly return or call EFI_BOOT_SERVICES.Exit(). Unfortunately U-Boot makes the incorrect assumption that EFI_BOOT_SERVICES.Exit() is always called. So the following application leads to a memory exception on the aarch64 architecture when returning: EFI_STATUS efi_main( EFI_HANDLE handle, EFI_SYSTEM_TABlE systable) { return EFI_SUCCESS; } With this patch the entry point is stored in the image handle.
