lmb: move lmb_map_update_notify() to EFI

2025-02-20T10:09:33+00:00

When building with qemu_arm64_defconfig with CONFIG_CC_OPTIMIZE_FOR_DEBUG=y
and CONFIG_EFI_LOADER=n an error undefined reference to efi_add_memory_map_pg
occurs.

Move the EFI dependent part of lmb_map_update_notify() to the EFI
sub-system.

efi_loader: Pass in the required parameters from EFI bootmeth

2025-01-26T10:06:57+00:00

Rather than setting up the global variables and then making the call,
pass them into function directly. This cleans up the code and makes it
all a bit easier to understand.

efi_loader: Expose efi_reinstall_protocol_interface in efi_loader.h

2025-01-05T01:30:48+00:00

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.

efi_loader: efi_net: add EFI_HTTP_PROTOCOL

2024-12-04T11:24:38+00:00

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.

Add an implementation of the EFI_IP4_CONFIG2_PROTOCOL. The protocol
is attached to the handle of the efi network device. This is the same
handle where snp and pxe are attached to.

efi_loader: net: add support to send http requests and parse http headers

2024-12-04T11:24:38+00:00

Add network-stack agnostic way to send an http request and
parse http headers from efi drivers. This uses wget as a
backend and communicates with it via efi_wget_info.

The function efi_net_do_request allocates a buffer on behalf of an
efi application using efi_alloc and passes it to wget to receive
the data. If the method is GET and the buffer is too small, it
re-allocates the buffer based on the last received Content-Length
header and tries again. If the method is HEAD it just issues one
request. So issuing a HEAD request (to update Content-Length) and
then a GET request is preferred but not required.

The function efi_net_parse_headers parses a raw buffer containing
an http header into an array of EFI specific 'http_header' structs.

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.
