efi: Rename END to EFI_DP_END

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

This exported symbol has a very generic name. Rename it to indicate that
it relates to EFI and device-paths.

Fix checkpatch warnings related to use of multiple assignments.

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.

efi_loader: efi_net: Add device path cache

2025-03-10T06:02:25+00:00

In preparation to support mutiple efi net udevices. Add a device path
cache to support device paths from multiple ethernet udevices.
The device paths can be added to the cache before EFI gets initialized and
the protocols get installed.

efi_loader: efi_device_path: Pass net udevice as argument

2025-03-10T06:01:37+00:00

In preparation to support multiple EFI net objects, support
constructing device paths using an ethernet device different
than the default. Add a udevice argument to the device path
generation, and keep the callsites with eth_get_dev() to
preserve existing functionality.

Merge tag 'efi-next-2024-12-04' of https://source.denx.de/u-boot/custodians/u-boot-efi into next

2024-12-04T17:56:00+00:00

CI: https://source.denx.de/u-boot/custodians/u-boot-efi/-/pipelines/23707

With this pull request support for the EFI_HTTP_PROTOCOL and
EFI_IP4_CONFIG2 protocols are added. This allows EFI applications
to load files via HTTP.

UEFI:
      add efi_dp_from_ipv4 function
      add efi_net_set_addr, efi_net_get_addr functions
      add support for HTTP device path
      set EFI bootdevice device path to HTTP when loaded from wget
      add support to send http requests and parse http headers
      provide EFI_IP4_CONFIG2_PROTOCOL
      provide EFI_HTTP_PROTOCOL
      support IPv4() in device path to text protocol
      provide unit tests for the HTTP and IPv4 Config2 protocols

Network:
      zero terminate string with headers in wget_fill_info()
      zero terminate string with headers in wget_lwip_fill_info()
      pass port and server_name via wget_ctx in lwIP network stack
      let wget_with_dns work with dns disabled

Others:
      Add HTTP and IPV4 Config II protocols to UUID library functions.

efi_loader: net: set EFI bootdevice device path to HTTP when loaded from wget

2024-12-04T11:24:37+00:00

Set the device path of the efi boot device to an HTTP device path
(as formed by efi_dp_from_http) when the next boot stage is loaded
using wget (i.e., when wget is used with wget_info.set_bootdev=1).

When loaded from HTTP, the device path should account for it so that
the next boot stage is aware (e.g. grub only loads its http stack if
it itself was loaded from http, and it checks this from its device path).

efi_loader: device_path: add support for HTTP device path

2024-12-04T11:24:37+00:00

Add efi_dp_from_http to form a device path from HTTP. The
device path is the concatenation of the device path returned
by efi_dp_from_ipv4 together with an URI node and an END node.

efi_loader: Change efi_dp_from_mem() to use size

2024-11-09T08:56:45+00:00

All call sites are using size rather than end addresses,
so instead - as previously done - calculating an end address
everywhere, just modify the function to use size and internally
calculate the end address
