* x86: Rename efi-x86 target to efi-x86_appBin Meng2018-06-171-4/+4
| | | | | | | To avoid confusion, let's rename the efi-x86 target to efi-x86_app. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
* x86: Add generic EFI payload supportBin Meng2018-06-171-10/+9
| | | | | | | | | | | It is possible to create a generic EFI payload for all x86 boards. The payload is configured to include as many generic drivers as possible. All stuff that touches low-level initialization are not allowed as such is the EFI BIOS's responsibility. Platform specific drivers (like gpio, spi, etc) are not included.

* x86: efi: Refactor the directory of EFI app and payload supportBin Meng2018-06-171-5/+1
| | | | | | | | | | | | | | At present the EFI application and payload support codes in the x86 directory is distributed in a hybrid way. For example, the Kconfig options for both app and payload are in arch/x86/lib/efi/Kconfig, but the source codes in the same directory get built only for CONFIG_EFI_STUB. This refactors the codes by consolidating all the EFI support codes into arch/x86/cpu/efi, just like other x86 targets.

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-071-3/+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_loader: split README.efi into two separate documentsHeinrich Schuchardt2018-02-101-0/+259
README.efi describes two different concepts: * U-Boot exposing the UEFI API * U-Boot running on top of UEFI. This patch splits the document in two. Religious references are removed. The separation of the concepts makes sense before detailing the internals of U-Boot exposing the UEFI API in a future patch.
