Jonathan Gray	b6e9e09770	efi_loader: initialise partition_signature memory ... Zero partition_signature in the efi_device_path_hard_drive_path structure when signature_type is 0 (no signature) as required by the UEFI specification. This is required so that efi_dp_match() will work as expected when doing memcmp() comparisons. Previously uninitialised memory would cause it not match nodes when it should have when the signature type was not GUID. Corrects a problem where the loaded image protocol would not return a device path with MEDIA_DEVICE causing the OpenBSD bootloader to fail on rpi_3 and other targets. v2: Also handle signature_type 1 (MBR) as described in the specification Signed-off-by: Jonathan Gray <jsg@jsg.id.au> Tested-by: Artturi Alm <artturi.alm@gmail.com> Signed-off-by: Alexander Graf <agraf@suse.de>	7 years ago
Heinrich Schuchardt	ff401d3f81	efi_loader: efi_dp_match should have const arguments ... efi_dp_match does not change its arguments. So they should be marked as const. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>	7 years ago
Rob Clark	bf19273e81	efi_loader: Add mem-mapped for fallback ... When we don't have a real device/image path, such as 'bootefi hello', construct a mem-mapped device-path. This fixes 'bootefi hello' after devicepath refactoring.

Rob Clark	b66c60dde9	efi_loader: add device-path utils ... Helpers to construct device-paths from devices, partitions, files, and for parsing and manipulating device-paths. For non-legacy devices, this will use u-boot's device-model to construct device-paths which include bus hierarchy to construct device-paths. For legacy devices we still fake it, but slightly more convincingly. Signed-off-by: Rob Clark <robdclark@gmail.com> Signed-off-by: Alexander Graf <agraf@suse.de>	7 years ago
