efi_loader: allow EFI_LOADER_BOUNCE_BUFFER on all architectures

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

2024-10-15T19:45:29Z

Use the LMB API's for allocating and freeing up memory. With this, the LMB module becomes the common backend for managing non U-Boot image memory that might be requested by other modules. Signed-off-by: Sughosh Ganu

efi_loader: Rename and move CMD_BOOTEFI_HELLO_COMPILE

2024-10-10T04:04:56Z

This is not actually a command so the name is confusing. Use BOOTEFI_HELLO_COMPILE instead. Put it in the efi_loader directory with the other such config options. The link rule (for $(obj)/%_efi.so) in scripts/Makefile.lib handles pulling in efi_crt0.o and efi_reloc.o so drop the 'extra' rules. Signed-off-by: Simon Glass Reviewed-by: Ilias Apalodimas

efi: add a helper to generate dynamic UUIDs

2024-09-12T15:35:37Z

Introduce a new helper efi_capsule_update_info_gen_ids() which populates the capsule update fw images image_type_id field. This allows for determinstic UUIDs to be used that can scale to a large number of different boards and board variants without the need to maintain a big list. We call this from efi_fill_image_desc_array() to populate the UUIDs lazily on-demand. Reviewed-by: Ilias Apalodimas Signed-off-by: Caleb Connolly

Kconfig: clean up the efi configuration status

2024-09-12T15:33:52Z

The EFI_LOADER and EFI config options are randomly scattered under lib/ making it cumbersome to navigate and enable options, unless you really know what you are doing. On top of that the existing options are in random order instead of a logical one. So let's move things around a bit and move them under boot/. Present a generic UEFI entry where people can select Capsules, Protocols, Services, and an option to compile U-Boot as an EFI for X86 Signed-off-by: Ilias Apalodimas Reviewed-by: Simon Glass

efi_loader: allow EFI_LOADER_BOUNCE_BUFFER on all architectures

There not only ARM64 boards but also RISC-V boards that require a bounce buffer to read block devices. Drop the architecture restriction. Signed-off-by: Heinrich Schuchardt

efi_loader: require EFI boot manager for EBBR compliance

A system has to support booting via the boot manager to be EBBR compliant. See the reference to variables Boot#### in the specification. Signed-off-by: Heinrich Schuchardt Reviewed-by: Ilias Apalodimas

efi_loader: adjust config options for capsule updates

2024-07-31T06:29:15Z

EFI_IGNORE_OSINDICATIONS is used to ignore OsIndications if setvariable at runtime is not supported and allow the platform to perform capsule updates on disk. With the recent changes boards can conditionally enable setvariable at runtime using EFI_RT_VOLATILE_STORE. Let's make that visible in our Kconfigs and enable EFI_IGNORE_OSINDICATIONS when set variable at runtime is disabled. Since EFI_RT_VOLATILE_STORE needs help from the OS to persist the variables, allow users to ignore OsIndications even if setvariable at runtime is enabled.
