* efi_loader: print file path w/o boot deviceHeinrich Schuchardt2023-05-131-4/+4
| | | | | | | Helloworld.efi should print the file path even if the boot device is not set. Signed-off-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com>

* efi_loader: printing UEFI revision in helloworld.efiHeinrich Schuchardt2022-09-031-12/+54
| | | | | | | | | | | | | | We need to support multiple digits in the parts of the UEFI verision number. E.g. EFI_SPECIFICATION_VERSION = (123 << 16) | 456 must be printed as 123.45.6 Signed-off-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com> Reviewed-by: Simon Glass <sjg@chromium.org>
* efi: Use 16-bit unicode stringsSimon Glass2022-02-031-20/+20
| | | | | | | | | | At present we use wide characters for unicode but this is not necessary. Change the code to use the 'u' literal instead. This helps to fix build warnings for sandbox on rpi.

| | | | | | | Let helloworld.efi print the device path of the boot device and the file path as provided by the loaded image protocol. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
* 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>
* efi_loader: use library memcpy() in helloworld.efiHeinrich Schuchardt2019-02-131-30/+6
| | | | | | | | Helloworld does not need its own memcpy() implementation anymore. Use the one provided in efi_freestanding.c. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
* efi_selftest: use CR LF in helloworldHeinrich Schuchardt2018-12-021-13/+27
| | | | | | | | | | | | The UEFI spec defines that a line feed moves the cursor to the next line and (only) a carriage return moves the cursor to the beginning of the line. So we should issue CR LF when we want to get to the start of the next line. Add some comments. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>

* 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_loader: helloworld.c: Explicitly use .rodata for loaded_image_guidAlexander Graf2017-12-161-1/+2
| | | | | | | | | | | | | | | | | | | | | Commit bbf75dd9345d0b ("efi_loader: output load options in helloworld") introduced a const variable in efi_main() called loaded_image_guid which got populated from a constant struct. While you would usually expect a compiler to realize that this variable should really just be a global pointer to .rodata, gcc disagrees and instead puts it on the stack. Unfortunately in some implementations of gcc it does so my calling memcpy() which we do not implement in our hello world environment. So let's explicitly move it to a global variable which in turn puts it in .rodata reliably and gets rid of the memcpy().
