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.

xilinx: Introduce XILINX_MINI configuration

2024-11-19T14:57:56+00:00

There is no common symbol which mini configurations are using and recent
get_mem_top() changes adding 1.3kB without having a way to remove it.
That's why introduce new symbol which can be used for removing features
which are not requested by these configurations.

xilinx: use get_mem_top() to compute ram_top

2024-11-15T13:32:47+00:00

Use the get_mem_top function to compute the value of ram_top. This was
earlier done through LMB API's, which are no longer available till
after relocation. Use get_mem_top() instead to compute the ram_top
value.

net: lwip: add DHCP support and dhcp commmand

2024-10-16T17:11:56+00:00

Add what it takes to enable NETDEVICES with NET_LWIP and enable DHCP as
well as the dhcp command. CMD_TFTPBOOT is selected by BOOTMETH_EFI due
to this code having an implicit dependency on do_tftpb().

Note that PXE is likely non-fonctional with NET_LWIP (or at least not
100% functional) because DHCP option 209 is not supported by the lwIP
library. Therefore, BOOTP_PXE_DHCP_OPTION cannot be enabled.
