* efi_loader: Check machine type in the image headerIvan Gorinov2018-04-061-0/+4
| | | | | | | | | Check FileHeader.Machine to make sure the EFI executable image is built for the same architecture. For example, 32-bit U-Boot on x86 will print an error message instead of loading an x86_64 image and crashing.

* efi_loader: fix building crt0 on armHeinrich Schuchardt2018-02-101-6/+2
| | | | | | | | | | | | | | | | | | | | | | Before the patch an undefined constant EFI_SUBSYSTEM was used in the crt0 code. The current version of binutils does not swallow the error. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=888403 The necessary constant IMAGE_SUBSYSTEM_EFI_APPLICATION is already defined in pe.h. So let's factor out asm-generic/pe.h for the image subsystem constants and use it in our assembler code. IMAGE_SUBSYSTEM_SAL_RUNTIME_DRIVER does not exist in the specification let's use IMAGE_SUBSYSTEM_EFI_ROM instead. The include pe.h is only used in code maintained by Alex so let him be the maintainer here too.

* efi_loader: set loaded image code/data type properlyRob Clark2017-09-201-0/+6
| | | | | | | | These should be set according to the image type. Shell.efi and SCT.efi use these fields to determine what sort of image they are loading. Signed-off-by: Rob Clark <robdclark@gmail.com> Signed-off-by: Alexander Graf <agraf@suse.de>
* efi_loader: Add PE image loaderAlexander Graf2016-03-151-0/+263
EFI uses the PE binary format for its application images. Add support to EFI PE binaries as well as all necessary bits for the "EFI image loader" interfaces. Signed-off-by: Alexander Graf <agraf@suse.de> Reviewed-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org>
