efi_loader: use LOGC_EFI consistently

2025-01-26T10:06:56Z

The log category should be LOGC_EFI all over the EFI sub-system. Signed-off-by: Heinrich Schuchardt Reviewed-by: Ilias Apalodimas

efi_loader: correct logging StartImage()

2025-01-26T10:06:56Z

When logging running an image, e.g. `bootefi hello` the indent is not correctly reset. Signed-off-by: Heinrich Schuchardt

efi_loader: Expose efi_reinstall_protocol_interface in efi_loader.h

2025-01-05T01:30:48Z

This is done so that the device path protocol interface of the network device can be changed internally by u-boot when a new bootfile gets downloaded. Signed-off-by: Adriano Cordova Reviewed-by: Heinrich Schuchardt Reviewed-by: Ilias Apalodimas

efi_loader: avoid writing message in Exit() boot service

2025-01-05T01:30:47Z

We should not write messages in UEFI API functions. This may lead to incorrect screen layout in UEFI application. For single statements after if clause we don't need braces. Reviewed-by: Ilias Apalodimas Signed-off-by: Heinrich Schuchardt

dm: Add dm_remove_devices_active() for ordered device removal

2024-11-24T21:41:28Z

This replaces dm_remove_devices_flags() calls in all boot implementations to ensure non vital devices are consistently removed first. All boot implementation except arch/arm/lib/bootm.c currently just call dm_remove_devices_flags(DM_REMOVE_ACTIVE_ALL). This can result in crashes when dependencies between devices exists. The driver model's design document describes DM_FLAG_VITAL as "indicates that the device is 'vital' to the operation of other devices". Device removal at boot should follow this. Instead of adding dm_remove_devices_flags() with (DM_REMOVE_ACTIVE_ALL | DM_REMOVE_NON_VITAL) everywhere add dm_remove_devices_active() which does this. Fixes a NULL pointer deref in the apple dart IOMMU driver during EFI boot. The xhci-pci (driver which depends on the IOMMU to work) removes its mapping on removal. This explodes when the IOMMU device was removed first. dm_remove_devices_flags() is kept since it is used for testing of device_remove() calls in dm. Signed-off-by: Janne Grunau

efi_loader: use list_count_nodes() in efi_protocols_per_handle()

2024-08-11T05:47:23Z

Simplify the code by using the list_count_nodes() function. Signed-off-by: Heinrich Schuchardt

efi_loader: export efi_load_image_from_path

We can reuse this function to load the device-tree. Signed-off-by: Heinrich Schuchardt Reviewed-by: Ilias Apalodimas

efi_loader: allow concatenation with contained end node

2024-06-10T09:43:36Z

Allow appending a device-path to a device-path that contains an end node as separator. We need this feature for creating boot options specifying kernel, initrd, and dtb. Signed-off-by: Heinrich Schuchardt Reviewed-by: Ilias Apalodimas

efi_loader: Clean up efi_dp_append and efi_dp_concat

2024-01-13T17:17:47Z

Looking back at the initrd storing functionality, we introduced three functions, efi_dp_append_or_concatenate(), efi_dp_append/concat(). In hindsight we could have simplified that by a lot. First of all none of the functions append anything. They all allocate a new device path and concatenate the contents of two device paths in one. A boolean parameter controls the final device path -- if that's true an end node is injected between the two device paths. So let's rewrite this and make it a bit easier to read. Get rid of efi_dp_append(), efi_dp_concat() and rename efi_dp_append_or_concatenate() to efi_dp_concat(). This is far more intuitive and the only adjustment that is needed is an extra boolean argument on all callsites. Signed-off-by: Ilias Apalodimas

efi_loader: Remove

We largely do not need in these files, so drop it. The only exception here is that efi_freestanding.c needs and had been getting that via . Reviewed-by: Simon Glass Signed-off-by: Tom Rini
