2025-05-29global: Avoid indirect inclusion of <env.h> from <net.h>Tom Rini
Now that env_get_ip() has been removed, the include file <net.h> does not need anything from <env.h>. Furthermore, include/env.h itself includes other headers which can lead to longer indirect inclusion paths. To prepare to remove <env.h> from <net.h> fix all of the remaining places which had relied on this indirect inclusion to instead include <env.h> directly.

2023-12-09bootflow: bootmeth_efi: Set bootp_arch as hexShantur Rathore
bootmeth_efi sets up bootp_arch which is read later in bootp.c Currently bootp_arch is being set as integer string and being read in bootp.c as hex, this sends incorrect arch value to dhcp server which in return sends wrong file for network boot. For ARM64 UEFI Arch value is 0xb (11), here we set environment as 11 and later is read as 0x11 and 17 is sent to dhcp server. Setting it as hex string fixes the problem.

2023-11-17bootstd: Avoid freeing a non-allocated bufferSimon Glass
EFI applications can be very large and thus used to cause boot failures when malloc() space was exhausted. A recent changed fixed this by using the kernel_addr_r environment var as the address of the buffer. However, it still frees the buffer when the bootflow is discarded. Fix this by introducing a flag to indicate whether the buffer was allocated, or not. Note that kernel_addr_r is not the last word here. It might be better to use lmb to place images. But there is a lot of refactoring to do before we can remove the environment variables. The distro scripts rely on them so it is safe for bootstd to do so too.

2023-08-03bootstd: Avoid allocating memory for the EFI fileSimon Glass
The current bootflow-iteration algorithm reads the bootflow file into an allocated memory buffer so it can be examined. This works well in most cases. However, while the common case is that the first bootflow is immediately booted, it is also possible just to scan for available bootflows, perhaps selecting one to boot later. Even with the common case, EFI bootflows can be quite large. It doesn't make sense to read it into an allocated buffer when we have kernel_addr_t providing a suitable address for it. Even if we do have plenty of malloc() space available, it is a violation of U-Boot's lazy-init principle to read the bootflow before it is needed. So overall it seems better to make a change. Adjust the logic to read just the size of the EFI file at first. Later, when the bootflow is booted, read the rest of the file into the designated kernel buffer.

2023-04-26bootstd: Support booting EFI where multiple options existSimon Glass
The current EFI implementation has a strange quirk where it watches loaded files and uses the last-loaded file to determine the device that is being booted from. This is confusing with bootstd, where multiple options may exist. Even loading a device tree will cause it to go wrong. There is no API for passing this information, since the only entry into booting an EFI image is the 'bootefi' command. To work around this, call efi_set_bootdev() for EFI images, if possible, just before booting. Signed-off-by: Simon Glass <sjg@chromium.org>

2023-01-23bootstd: Treat DHCP and PXE as bootdev labelsSimon Glass
These are associated with the ethernet boot device but do not match its uclass name, so handle them as special cases. Provide a way to pass flags through with the bootdev so that we know how to process it. The flags are checked by the bootmeths, to ensure that only the selected bootmeth is used. While these both use the network device, they work quite differently. It is common to run only one of these, or to run PXE before DHCP. Provide bootflow flags to control which methods are used. Check these in the two bootmeths so that only the chosen one is used. Signed-off-by: Simon Glass <sjg@chromium.org>

Add a bootmeth driver which handles EFI boot, using EFI_LOADER. In effect, this provides the same functionality as the 'bootefi' command and shares the same code. But the interface into it is via a bootmeth, so it does not require any special scripts, etc. For now this requires the 'bootefi' command be enabled. Future work may tidy this up so that it can be used without CONFIG_CMDLINE being enabled. There was much discussion about whether this is needed, but it seems that it is, at least for now.
