dfu: Make the DFU_WRITE_ALT symbol available outside of DFU

2026-03-16T09:38:47+00:00

The DFU_WRITE_ALT symbol is used both directly and indirectly (via
UPDATE_COMMON) for EFI capsule updates (FIT or raw), but does not depend
on DFU itself. Move this symbol outside of "if DFU" to remove a Kconfig
dependency problem.

Kconfig: Make further use of testing for !COMPILE_TEST

2025-10-08T22:12:41+00:00

We have a large number of library symbols that should not be prompted
for by the user really but rather selected by the platform (or SoC) as
needed. To start with however, make these depend on !COMPILE_TEST.

dfu: add scsi backend

2024-11-20T16:57:58+00:00

This is extremely similar to the MMC backend, but there are some notable
differences.

Works with a DFU string like

    scsi 4=u-boot-bin part 11

Where "4" is the SCSI dev number (sequential LUN across all SCSI devices)
and "11" is the partition number.

net: introduce alternative implementation as net/lwip/

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

Prepare the introduction of the lwIP (lightweight IP) TCP/IP stack by
adding a new net/lwip/ directory and the NET_LWIP symbol. Network
support is either NO_NET, NET (legacy stack) or NET_LWIP. Subsequent
commits will introduce the lwIP code, re-work the NETDEVICE integration
and port some of the NET commands and features to lwIP.

SPL_NET cannot be enabled when NET_LWIP=y. SPL_NET pulls some symbols
that are part of NET (such as arp_init(), arp_timeout_check(),
arp_receive(), net_arp_wait_packet_ip()). lwIP support in SPL may be
added later.

Similarly, DFU_TFTP and FASTBOOT are not compatible with NET_LWIP
because of dependencies on net_loop(), tftp_timeout_ms,
tftp_timeout_count_max and other NET things. Let's add a dependency on
!NET_LWIP for now.

SANDBOX can select NET_LWIP but doing so will currently disable the eth
dm tests as well as the wget tests which have strong dependencies on the
NET code.

Other adjustments to Kconfig files are made to fix "unmet direct
dependencies detected" for USB_FUNCTION_SDP and CMD_FASTBOOT when
the default networking stack is set to NET_LWIP ("default NET_LWIP"
instead of "default NET" in Kconfig).

The networking stack is now a choice between NO_NET,
NET and NET_LWIP. Therefore '# CONFIG_NET is not set' should be
'CONFIG_NO_NET=y'. Adjust the defconfigs accordingly.

dfu: fix Kconfig dependencies

2024-09-13T15:41:18+00:00

Fix link errors caused by missing Kconfig dependencies:

1. DFU_OVER_USB compiles common/dfu.c which calls g_dnl_clear_detach()
which is implemented in drivers/usb/gadget/g_dnl.c which needs
USB_GADGET_DOWNLOAD. Test case:

 $ printf "CONFIG_USB_GADGET_DOWNLOAD=n\nCONFIG_USB_FUNCTION_FASTBOOT=n" \
       >>configs/am62px_evm_a53_defconfig
 $ make am62px_evm_a53_defconfig
 $ make CROSS_COMPILE=aarch64-linux-gnu-
 [...]
 common/dfu.c:34:(.text.run_usb_dnl_gadget+0x68): undefined reference to `g_dnl_clear_detach
 [...]

2. With the above fixed, the same build causes:

 common/spl/spl_dfu.c:29:(.text.spl_dfu_cmd+0xb0): undefined reference to `run_usb_dnl_gadget'

This is because SPL_DFU compiles common/spl/spl_dfu.c which calls
run_usb_dnl_gadget() which is implemented in common/dfu.c which needs
DFU_OVER_USB.

Therefore add these dependencies to Kconfig.

dfu: add CONFIG_DFU_NAME_MAX_SIZE configuration

2023-11-21T14:28:15+00:00

Add CONFIG_DFU_NAME_MAX_SIZE to change the proper size.
If name is longer than default size, it can do wrong behavior during updating
image. So it need to change the proper maximum size.

This patch is proviced the solution to change value with configuration.

dfu: mtd: remove direct call of mtdparts_init function

2023-06-16T09:01:16+00:00

With MTD support in driver model, the direct call of mtdparts_init
should be avoided and replaced by mtd_probe_devices.

With the modificaton when MTDIDS/MTDPARTS are empty the OF fallback
with partition describe in device tree is correctly performed,
introduced by commit dc339bf784f0 ("mtd: add support for parsing
partitions defined in OF").
With this patch the dependency with CONFIG_CMD_MTDPARTS is removed.
