efi: add EFI_DEBUG_IMAGE_INFO for debug

2025-07-03T09:25:56+00:00

This commit adds the functionality of generate EFI_DEBUG_IMAGE_INFO
while loading the image.

This feature is described in UEFI Spec 2.10. Section 18.4.3.
The implementation ensures support for hardware-assisted debugging and
provides a standardized mechanism for debuggers to discover the load
address of an EFI application.

efi: drop volatile qualifier from "save gd" variables

2025-06-13T22:57:15+00:00

The global gd pointer is no longer volatile-qualified, so drop that
qualifier from these bookkeeping variables.

efi_loader: Separate device path into its own header

2025-05-25T09:27:18+00:00

These functions are useful for the EFI app. As a first step towards
making these available outside lib/efi_loader, create a separate header
file and include it where needed. Add proper comments to the functions,
since many are missing at present.

Note that this undoes the changes of commit cf6d4535cc4c ("x86:
emulation: Disable bloblist for now") as that was intended only for the
release due to time.

efi_loader: stop network in EXIT_BOOT_SERVICES

2025-04-06T16:03:22+00:00

It has been reported that memory corruption can occurred because network
packages where received after EXIT_BOOT_SERVICES. See the thread
starting at [1].

We try to remove all drivers when EXIT_BOOT_SERVICES is called. But

* Some network drivers don't call their own stop method when removed.
* Some network drivers don't have a remove method.
* Some devices have CONFIG_DM_DEVICE_REMOVE=n.

Let's call eth_halt() in EXIT_BOOT_SERVICES explicitly.

efi_loader: Clean up usage of structure jmp_buf_data

2025-03-10T06:41:20+00:00

Structure jmp_buf_data provides the underlying format of jmp_buf, which
we actually don't care about. Clean up existing code to use the standard
jmp_buf type. This introduces no functional change.

common: clean up setjmp.h

2025-03-10T06:41:16+00:00

Separate setjmp.h into an architecture independent part and an architecture
specific part. This simplifies moving from using struct jmp_buf_data
directly to using type jmp_buf in our code which is the C compliant way.
