2018-09-23efi_loader: refactor efi_setup_loaded_image()Heinrich Schuchardt
Create the handle of loaded images and the EFI_LOADED_IMAGE_PROTOCOL inside efi_setup_loaded_image(). Do not use local variables. Currently we expect the loaded image handle to point to the loaded image protocol. Additionally we have appended private fields to the protocol. With the patch the handle points to a loaded image object and the private fields are added here. This matches how we handle the net and the gop object.

2018-09-23efi_loader: remove efi_exit_caches()Heinrich Schuchardt
Since GRUB patch d0c070179d4d ("arm/efi: Switch to arm64 linux loader", 2018-07-09) we do not need a workaround for GRUB on 32bit ARM anymore. So let's eliminate function efi_exit_caches(). This will require Linux distributions to update grub-efi-arm to the GRUB git HEAD (a tag containing the aforementioned GRUB patch is not available yet).

2018-09-23efi_loader: create root nodeHeinrich Schuchardt
Currently we assign a lot of protocols to loaded images though these protocols are not related to them. Instead they should be installed on a separate handle.

2018-09-10Remove <inttypes.h> includes and PRI* usages in printf() entirelyMasahiro Yamada
In int-ll64.h, we always use the following typedefs: typedef unsigned int u32; typedef unsigned long uintptr_t; typedef unsigned long long u64; This does not need to match to the compiler's <inttypes.h>. Do not include it. The use of PRI* makes the code super-ugly. You can simply use "l" for printing uintptr_t, "ll" for u64, and no modifier for u32.

2018-08-20efi_loader: fix a parameter check at CreateEvent()AKASHI Takahiro
The commit 21b3edfc9644 ("efi_loader: check parameters of CreateEvent") enforces a strict parameter check at CreateEvent(). On the other hand, UEFI specification version 2.7, section 7.1, says: The EVT_NOTIFY_WAIT and EVT_NOTIFY_SIGNAL flags are exclusive. If neither flag is specified, the caller does not require any notification concerning the event and the NotifyTpl, NotifyFunction, and NotifyContext parameters are ignored. So the check should be mitigated so as to comply with the specification. Without this patch, EDK2's Shell.efi won't be started.

2018-07-25efi_loader: allocate configuration table arrayHeinrich Schuchardt
The system table contains a link to the list of configurations tables. These include the device tree, SMBIOS table, and the ACPI table. This array is currently statically linked. With the patch it is allocated as EFI_RUNTIME_SERVICES_DATA. Due to the structure of the system table we cannot work with a linked list here.

2018-07-25efi_loader: Introduce ms abi vararg helpersAlexander Graf
Varargs differ between sysv and ms abi. On x86_64 we have to follow the ms abi though, so we also need to make sure we use x86_64 varargs helpers. This patch introduces generic efi vararg helpers that adhere to the respective EFI ABI. That way we can deal with them properly from efi loader code and properly interpret variable arguments. This fixes the InstallMultipleProtocolInterfaces tests in the efi selftests on x86_64 for me. Signed-off-by: Alexander Graf <agraf@suse.de>
2018-07-23doc: Replace DocBook with sphinx-based docsMario Six
The Linux kernel moved to sphinx-based documentation and got rid of the DocBook based documentation quite a while ago. Hence, the DocBook documentation for U-Boot should be converted as well. To achieve this, import the necessary files from Linux v4.17, and convert the current DocBook documentation (three files altogether) to sphinx/reStructuredText. For now, all old DocBook documentation was merged into a single handbook, tentatively named "U-Boot Hacker Manual". For some source files, the documentation style was changed to comply with kernel-doc; no functional changes were applied. Signed-off-by: Mario Six <mario.six@gdsys.cc>

2018-04-23efi_loader: correcty determine total device path lengthHeinrich Schuchardt
Device paths may consist of multiple instances. Up to now we have only considered the size of the first instance.
