* efi_loader: adjust definitions of variable servicesHeinrich Schuchardt2018-06-031-12/+12
| | | | | | | | | | | The definitons of the variable services are adjusted: - use efi_uintn_t instead of unsigned long - use u16 * instead of s16 * for Unicode strings - correct definition of QueryVariableInfo - rename efi_get_next_variable to efi_get_next_variable_name Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>

| | | | | | | | | | | | | | | This patch lets the implementation of ExitBootServices conform to the UEFI standard.

* efi_loader: add bootmgrRob Clark2017-09-201-0/+4
| | | | | | | | | | | | | | | 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.)
