global_data: Only include driver model fields when DM is enabled

2026-08-18T00:46:29Z

The struct list_head dmtag_list, struct udevice *dm_root, struct list_head uclass_root_s and struct list_head *uclass_root fields in struct global_data takes up 24/48 bytes of memory on ARMv7/AArch64. However, these fields are only used when $(PHASE_)DM is enabled. Guard driver model related fields using CONFIG_IS_ENABLED(DM) to save memory space when U-Boot proper is built with DM=y and xPL is built without xPL_DM.

bloblist: Rename GD_FLG_BLOBLIST_READY to GD_FLG_BLOBLIST_HANDOFF

2026-07-17T20:50:28Z

Now that we have made bloblist have distinct "find" and "create" functions, the global data tag "GD_FLG_BLOBLIST_READY" doesn't quite make sense anymore. Rename it to GD_FLG_BLOBLIST_HANDOFF. Suggested-by: Raymond Mao Reviewed-by: Raymond Mao Signed-off-by: Tom Rini

treewide: move bi_dram[] from bd to gd

2026-06-25T00:13:24Z

Currently, the bi_dram[] information is stored in the board info structure (bd). Because bd is only valid after reserve_board(), dram_init_banksize() must be called late in the initialization process. This limitation is problematic, as it forces us to rely on a variety of bespoke functions to determine board RAM, bank memory sizes, and other early setup requirements. By moving bi_dram[] into the global data (gd), we can run it earlier. This is particularly convenient since boards define their own dram_init_banksize() routines, which do not always rely on parsing Device Tree (DT) memory nodes. Additionally, U-Boot defaults to relocating to the top of the first memory bank. While boards currently use custom functions to override this behavior, having the DRAM bank information available earlier in gd makes relocating to a different bank trivial and standardizes the process.

global_data: fix type for gd_malloc_ptr()

2026-06-23T18:36:26Z

With commit 92aa3ec321b5 ("global_data: Reduce size of early-malloc vars") the type changes from (unsigned) long to int. But the type for default if SYS_MALLOC_F_LEN is unset was not changed. Remove the suffix. Fixes the warning: common/spl/spl.c:800:23: warning: format '%x' expects argument of type 'unsigned int', but argument 2 has type 'long int' [-Wformat=] Fixes: 92aa3ec321b5 ("global_data: Reduce size of early-malloc vars") Signed-off-by: Alexander Stein Reviewed-by: Simon Glass

memory: reserve from start_addr_sp to initial_relocaddr

2026-06-15T17:04:39Z

Add a new global data struct member called initial_relocaddr. This stores the original value of relocaddr, directly from setup_dest_addr. This is specifically to avoid any adjustments made by other init functions. Reserve the memory from gd->start_addr_sp - CONFIG_STACK_SIZE to gd->initial_relocaddr instead of gd->ram_top. This allows platform specific relocation addresses to work without unnecessarily painting over a large range. Signed-off-by: Randolph Sapp Reviewed-by: Simon Glass Reviewed-by: Ilias Apalodimas

string: add strdup_const and kstrdup_const

2026-04-21T17:19:49Z

Extend Linux compat by adding kstrdup_const(), backed by lib/string.c. This leverages U-Boots .rodata section on ARM64 to avoid pointlessly duplicating const strings. This is used by the Linux CCF_FULL port and may be useful elsewhere in U-Boot. Signed-off-by: Casey Connolly

dm: Remove pre-schema tag support

2025-11-10T17:30:56Z

Support for using "u-boot,dm-..." rather than "bootph-..." has been deprecated since February 2023. Any platforms using this have had a console message saying to migrate by 2023.07. Go and remove all support here now, for the v2026.01 release. The results of this change that aren't clear from the above are that we still have a checkpatch.pl error message, and document in doc/develop/spl.rst that they have been migrated since 2023. We also change the key2dtsi.py tool to use the correct bootph phase rather than the legacy phase. Signed-off-by: Tom Rini

efi_loader: Move public cert for capsules to .rodata

2025-04-11T11:25:31Z

commit ddf67daac39d ("efi_capsule: Move signature from DTB to .rodata") was reverted in commit 47a25e81d35c ("Revert "efi_capsule: Move signature from DTB to .rodata"") because that's what U-Boot was usually doing -- using the DT to store configuration and data. Some of the discussions can be found here [0]. (Ab)using the device tree to store random data isn't ideal though. On top of that with new features introduced over the years, keeping the certificates in the DT has proven to be problematic. One of the reasons is that platforms might send U-Boot a DTB from the previous stage loader using a transfer list which won't contain the signatures since other loaders are not aware of internal U-Boot ABIs. On top of that QEMU creates the DTB on the fly, so adding the capsule certificate there does not work and requires users to dump it and re-create it injecting the public keys. Now that we have proper memory permissions for arm64, move the certificate to .rodata and read it from there.
