2017-07-28efi_loader: only evaluate EFI_EXIT()'s ret onceRob Clark
There are a couple spots doing things like: return EFI_EXIT(some_fxn(...)); which I handn't noticed before. With addition of printing return value in the EFI_EXIT() macro, now the fxn call was getting evaluated twice. Which we didn't really want.

2017-07-26efi_loader: fix bug in efi_get_memory_mapRob Clark
When booting shim -> fallback -> shim -> grub -> linux the memory map is a bit larger than the size linux passes in on the first call. But in the EFI_BUFFER_TOO_SMALL case we were not passing back the updated size to linux so it would loop forever.

2017-07-26efi_loader: Fix configuration table overrideAlexander Graf
Before commit 7cbc12415d ("efi_loader: initalize EFI object list only once") we recreated the world on every bootefi invocation. That included the object tree as well as the configuration tables. Now however we don't recreate them, which means we must not explicitly override the configuration tables, as otherwise we may lose our SMBIOS table from the configuration table list on second bootefi invocation. This patch makes bootefi call our normal configuration table modification APIs to add/remove the FDT instead of recreating all tables from scratch. That way the SMBIOS table gets preserved across multiple invocations. Signed-off-by: Alexander Graf <agraf@suse.de>

2017-07-25efi_loader: expose protocols via GUIDRob Clark
shim.efi (or rather gnu-efi's LibLocateProtocol() which shim.efi uses) resolves protocols via efi_locate_handle() so the console protocols need to be added to the efi object list. Signed-off-by: Rob Clark <robdclark@gmail.com> [agraf: whitespace fixes] Signed-off-by: Alexander Graf <agraf@suse.de>
2017-07-25efi_loader: add helper macro to construct protocol objectsRob Clark
There are a bunch of protocols which should be exposed by GUID but are not. Add a helper macro to create an efi_object, to avoid much typing. Note that using the pointer for efiobj->handle is semi-arbitrary. We just need a unique value to match the efiobj supporting the protocol with the handle that LocateHandle() returns.. See LibLocateProtocol() in gnu-efi. It does LocateHandle() to find all the handles, and then loops over them calling HandleProtocol() with the GUID of the protocol it is trying to find.

2017-07-19efi_loader: disk: iterate only over valid block devicesxypron.glpk@gmx.de
The efi_loader currently stops iterating over the available block devices stopping at the first device that fails. This may imply that no block device is found. With the patch efi_loader only iterates over valid devices. It is based on patch 06d592bf52f6 (dm: core: Add uclass_first/next_device_check()) which is currently in u-boot-dm.git. For testing I used an odroid-c2 with a dts including &sd_emmc_a { status = "okay"; }; This device does not exist on the board and cannot be initialized.

2017-07-19bootefi: allow return without EFI_BOOT_SERVICES.Exitxypron.glpk@gmx.de
The Unified Extensible Firmware Interface Specification, version 2.7, defines in chapter 2.1.2 - UEFI Application that an EFI application may either directly return or call EFI_BOOT_SERVICES.Exit(). Unfortunately U-Boot makes the incorrect assumption that EFI_BOOT_SERVICES.Exit() is always called. So the following application leads to a memory exception on the aarch64 architecture when returning: EFI_STATUS efi_main( EFI_HANDLE handle, EFI_SYSTEM_TABlE systable) { return EFI_SUCCESS; } With this patch the entry point is stored in the image handle.

2017-07-11dm: ofnode: use fdt32_t for DT property value to fix sparse warningMasahiro Yamada
DTB is encoded in big endian. When we retrieve property values, we need to use fdt32_to_cpu (aka be32_to_cpu) for endian conversion. This is a bit error-prone, but sparse is useful to detect endian mismatch. We need to use (fdt32_t *) instead of (u32 *) for a pointer of a property value.
