* lib: Remove <common.h> inclusion from these filesTom Rini2023-12-211-1/+0
| | | | | | | | | | After some header file cleanups to add missing include files, remove common.h from all files in the lib directory. This primarily means just dropping the line but in a few cases we need to add in other header files now. Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Rini <trini@konsulko.com>

* efi: Move exit_boot_services into a functionSimon Glass2022-01-151-55/+11
| | | | | | | | | | | | | | | At present this code is inline in the app and stub. But they do the same thing. The difference is that the stub does it immediately and the app doesn't want to do it until the end (when it boots a kernel) or not at all, if returning to UEFI. Move it into a function so it can be called as needed. Add a comment showing how to store the memory map so that it can be accessed within the app if needed, for debugging purposes only. The map can change without notice. Signed-off-by: Simon Glass <sjg@chromium.org>

* dm: core: Create a new header file for 'compat' featuresSimon Glass2020-02-051-0/+1
| | | | | | | | | | | | At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

* efi_loader: consistent naming of protocol GUIDsHeinrich Schuchardt2019-04-231-1/+1
| | | | | | | | | | | | | We should consistently use the same name for protocol GUIDs as defined in the UEFI specification. Not adhering to this rule has led to duplicate definitions for the EFI_LOADED_IMAGE_PROTOCOL_GUID. Adjust misnamed protocol GUIDs. Adjust the text for the graphics output protocol in the output of the `efidebug dh` command. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

* x86: use EFI calling convention for efi_main on x86_64Ivan Gorinov2018-06-171-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | UEFI specifies the calling convention used in Microsoft compilers; first arguments of a function are passed in (%rcx, %rdx, %r8, %r9). All other compilers use System V ABI by default, passing first integer arguments of a function in (%rdi, %rsi, %rdx, %rcx, %r8, %r9). These ABI also specify different sets of registers that must be preserved across function calls (callee-saved). GCC allows using the Microsoft calling convention by adding the ms_abi attribute to a function declaration. Current EFI implementation in U-Boot specifies EFIAPI for efi_main() in the test apps but uses default calling convention in lib/efi. Save efi_main() arguments in the startup code on x86_64; use EFI calling convention for _relocate() on x86_64; consistently use EFI calling convention for efi_main() everywhere.

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-071-2/+1
| | | | | | | | | | | | | | | | | | | | When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

* efi: Add support for loading U-Boot through an EFI stubSimon Glass2015-08-051-0/+304
It is useful to be able to load U-Boot onto a board even if is it already running EFI. This can allow access to the U-Boot command interface, flexible booting options and easier development. The easiest way to do this is to build U-Boot as a binary blob and have an EFI stub copy it into RAM. Add support for this feature, targeting 32-bit initially. Also add a way to detect when U-Boot has been loaded via a stub. This goes in common.h since it needs to be widely available so that we avoid redoing initialisation that should be skipped.
