2017-10-09efi_selftest: avoid dereferencing NULL in tpl testHeinrich Schuchardt
The task priority levels test uses two events one passes the notification counter as context. The other passes NULL. Both use the same notification function. So we need to check for NULL here.

2017-10-09efi_loader: supply EFI network testHeinrich Schuchardt
This patch provides an EFI application to check the correct function of the Simple Network Protocol implementation. It sends a DHCP request and analyzes the DHCP offer. Different error conditions including a 10s timeout are checked. A successful execution will look like this: => bootefi nettest Scanning disk ide.blk#0...

2017-09-20efi_loader: add bootmgrRob Clark
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.)

2017-09-20efi_loader: efi variable supportRob Clark
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: Rob Clark <robdclark@gmail.com> Signed-off-by: Alexander Graf <agraf@suse.de>
