efi_loader: Depend on BLK

2025-01-21T01:26:54Z

In reworking the BLK usage in Kconfig, I found there's a few issues with EFI_LOADER=y and BLK=n. In general, we can easily say that lib/efi_loader/efi_file.c also should only be built with CONFIG_BLK. That however leaves the bootmgr code, eficonfig code and then parts of efi_device_path.c, efi_boottime.c and efi_setup.c which functionally depend on BLK. While these calls can be if'd out, I'm unsure if the result is usable. So rather than leave that buildable and imply that it is, I'm leaving that combination non-buildable and commenting that EFI_LOADER depends on BLK in the Kconfig currently.

efi_loader: Fix Kconfig logic around OF_LIBFDT

2024-12-04T20:00:45Z

Given that OF_LIBFDT is library functionality, the feature of EFI_LOADER needs to select OF_LIBFDT rather than depend on it being already enabled. Acked-by: Heinrich Schuchardt Signed-off-by: Tom Rini

efi_loader: efi_net: add EFI_HTTP_PROTOCOL

2024-12-04T11:24:38Z

Add an EFI HTTP driver. This commit implements the EFI_HTTP_PROTOCOL and the EFI_HTTP_SERVICE_BINDING_PROTOCOL. The latter is attached to the handle of th efi network device. This is the same handle where snp, pxe, and ipconfig are attached to. Signed-off-by: Adriano Cordova

efi_loader: Add a test app

2024-11-09T08:59:41Z

Add a simple app to use for testing. This is intended to do whatever it needs to for testing purposes. For now it just prints a message and exits boot services. There was a considerable amount of discussion about whether it is OK to call exit-boot-services and then return to U-Boot. This is not normally done in a real application, since exit-boot-services is used to completely disconnect from U-Boot. For now, this part is skipped.

efi_loader: fix CONFIG_EFI_HTTP dependencies

2024-10-30T13:54:28Z

CONFIG_CMD_DNS and CONFIG_CMD_WGET depend on CONFIG_CMD_NET. CONFIG_CMD_NET depends on CONFIG_NET or CONFIG_NET_LWIP. We shall only enable CONFIG_EFI_HTTP if there is network support. We have to select CONFIG_CMD_NET. Fixes: d7d07a8b508b ("efi_loader: support boot from URI device path") Signed-off-by: Heinrich Schuchardt Reviewed-by: Simon Glass Reviewed-by: Ilias Apalodimas

efi: memory: use the lmb API's for allocating and freeing memory
