simplify NET_LEGACY || NET_LWIP condition with NET condition

2026-04-27T17:26:40+00:00

Since the move to make NET a menuconfig and NO_NET a synonym of NET=n,
when NET is enabled, NET_LEGACY || NET_LWIP is necessarily true, so
let's simplify the various checks across the codebase.

SPL_NET_LWIP doesn't exist but SPL_NET_LEGACY is an alias for SPL_NET so
the proper symbol is still defined in SPL whenever needed.

rename NET to NET_LEGACY

2026-04-27T17:26:40+00:00

Highlight that NET really is the legacy networking stack by renaming the
option to NET_LEGACY.

This requires us to add an SPL_NET_LEGACY alias to SPL_NET as otherwise
CONFIG_IS_ENABLED(NET_LEGACY) will not work for SPL.

The "depends on !NET_LWIP" for SPL_NET clearly highlights that it is
using the legacy networking app so this seems fine to do.

This also has the benefit of removing potential confusion on NET being a
specific networking stack instead of "any" network stack.

board: xilinx: Retry FRU EEPROM read on timeout

2025-12-19T07:25:27+00:00

Wrap the dm_i2c_read() call is used for FRU EEPROM reads in a
retry loop, attempting up to EEPROM_FRU_READ_RETRY times if a
-ETIMEDOUT error is returned. The loop exits immediately on
success or any error other than -ETIMEDOUT. This improves
robustness against transient I2C timeouts during FRU detection
and decoding.

board: xilinx: Update ESRT after copying GUID

2025-12-19T07:25:26+00:00

The EFI System Resource Table (ESRT) is updated after the firmware
image GUID is copied to the fw_images structure. This ensures that
the ESRT accurately reflects the current firmware resources.

board: xilinx: update guid based on metadata

2025-10-09T07:07:04+00:00

The generated GUID applies to all Xilinx platforms but is not
specific to any individual board. For FWU multi bank update,
use the image UUID (GUID) from the FWU metadata structure
rather than embedding a generated GUID into the U-Boot build.

board: xilinx: Store board info data in data section

2025-04-16T13:39:48+00:00

Line 171 in README is describing that before relocation no code
should use global variable because global variables are placed
to BSS section which is initialized to 0 after relocation.

In the case of ZynqMP, where DTB reselection is enabled, the EEPROM
is read again after relocation. This prevents the issue from being
observed. However, in Versal Gen 2, where DTB reselection is also
enabled, the EEPROM is not read after relocation because it is not
yet wired in board_init(). This leads to a situation where the code
accesses an incorrect memory location, because none is really
checking the board_info is valid or not. To fix, move the board_info
into the data section and also check whether it is valid or not.

board: remove capsule update support in set_dfu_alt_info()

2025-04-11T11:20:37+00:00

Now that capsule update sets the dfu_alt_info environment variable
explicitly, there is no need to support it in the set_dfu_alt_info()
function. Decouple SET_DFU_ALT_INFO from EFI_CAPSULE_FIRMWARE_FIT and
EFI_CAPSULE_FIRMWARE_RAW. For many boards, this was the only use of
set_dfu_alt_info() so remove the function entirely.

fdt: Swap the signature for board_fdt_blob_setup()

2024-12-18T21:18:59+00:00

This returns a devicetree and updates a parameter with an error code.
Swap it, since this fits better with the way U-Boot normally works. It
also (more easily) allows leaving the existing pointer unchanged.

No yaks were harmed in this change, but there is a very small code-size
reduction.

For sifive, the OF_BOARD option must be set for the function to be
called, so there is no point in checking it again. Also OF_SEPARATE is
defined always.
