2018-06-14riscv: Add support for HI20 PE relocationsAlexander Graf
The PE standard allows for HI20/LOW12 relocations. Within the efi_loader target we always know that our relocation target is 4k aligned, so we don't need to worry about the LOW12 part. This patch adds support for the respective relocations. With this and a few grub patches I have cooking in parallel I'm able to run grub on RISC-V. Signed-off-by: Alexander Graf <agraf@suse.de>
2018-05-10SPDX: Convert a few files that were missed beforeTom Rini
As part of the main conversion a few files were missed. These files had additional whitespace after the '*' and before the SPDX tag and my previous regex was too strict. This time I did a grep for all SPDX tags and then filtered out anything that matched the correct styles. Fixes: 83d290c56fab ("SPDX: Convert all of our single license tags to Linux Kernel style") Reported-by: Heinrich Schuchardt <xypron.debian@gmx.de> Signed-off-by: Tom Rini <trini@konsulko.com>
2018-04-06efi_loader: Check machine type in the image headerIvan Gorinov
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.

2018-02-10efi_loader: fix building crt0 on armHeinrich Schuchardt
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.

2017-09-20efi_loader: set loaded image code/data type properlyRob Clark
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>
2016-03-15efi_loader: Add PE image loaderAlexander Graf
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>
