board: xilinx: Generate FWU capsule dfu_alt_info from fwu_platform_hook()

2026-08-12T04:54:37Z

Commit 371a6c1744f3 ("board: xilinx: Add capsule and FWU support") and commit 818c06faa119 ("board: amd: Add capsule and FWU support") introduced a separate set_dfu_alt_info() for the FWU multi-bank case (Versal and Versal Gen 2 respectively) which set the dfu_alt_info environment variable directly, while configure_capsule_updates() handled the non-FWU case by filling update_info.dfu_string. Fold the FWU multi-bank generation (fwu_gen_alt_info_from_mtd() over the nor0 MTD partitions) into fwu_platform_hook() and drop the standalone set_dfu_alt_info().

board: xilinx: Add FWU boot index support

2026-06-08T08:50:05Z

Add fwu_plat_get_alt_num() and fwu_plat_get_bootidx() platform callbacks required for FWU multi-bank update on Versal and Versal Gen 2. The boot index is read from the PMC Global PGGS4 register which is populated by PLM with a magic number and boot partition index. Uses firmware IOCTL when CONFIG_ZYNQMP_FIRMWARE is enabled, otherwise falls back to direct MMIO read.

simplify NET_LEGACY || NET_LWIP condition with NET condition

2026-04-27T17:26:40Z

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

2026-04-27T17:26:40Z

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

2025-12-19T07:25:27Z

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 guid based on metadata

2025-10-09T07:07:04Z

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

2025-04-16T13:39:48Z

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()

2025-04-11T11:20:37Z

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.
