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

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

test: Allow saving and restoring the bloblist

2024-11-04T03:27:12Z

Tests which create a new bloblist overwrite the existing one in sandbox. Provide a flag for tests to declare this behaviour. Save and restore the bloblist pointer so that other tests remain unaffected. Note that when sandbox is running normally, the bloblist has been relocated to high in memory. The existing bloblist tests create a new bloblist low in memory, so they do not conflict. Correct a build error on coreboot by using accessors for gd->bloblist: Signed-off-by: Simon Glass

Merge patch series "Allow showing the memory map"

Simon Glass says: This little series adds a new 'memmap' command, intended to show the layout of memory within U-Boot and how much memory is available for loading images. Link: https://lore.kernel.org/r/20241021081934.289473-1-sjg@chromium.org
