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.

Merge patch series "bootm: Clean up arch-specific, pre-OS clean-up"

2026-03-19T00:36:50Z

Simon Glass says: Each arch does something slightly different before booting the OS. Some archs even do different things depending on the CPU type. It is quite hard to know what actually happens in the final milliseconds before the OS boot. This series attempts to start cleaning up U-Boot in this area. The basic intent is to create a new bootm_final() function which can be called by all archs. It provides some flags for a couple of necessary variations but otherwise it is generic. All architectures are converted over to use this new function. board_quiesce_devices() is moved into bootm_final() so that all archs benefit from it. This series fixes a bug in device_remove() is fixed where removing a parent with specialised flags (e.g. DM_REMOVE_ACTIVE_ALL) could leave children activated, since they do not match the flags. This fixes is needed to avoid bootm_final() causing test failures on sandbox. Future work could take this a little further: - Convert EFI loader to use the same function - Improve comments for cleanup_before_linux() across architectures - Support fake-run tracing on all archs Link: https://lore.kernel.org/r/20260306023638.2678886-1-sjg@chromium.org

riscv: Call bootm_final()

2026-03-18T19:17:34Z

The RISC-V announce_and_cleanup() duplicates the common pre-boot steps. Replace it with a call to bootm_final(). Move board_quiesce_devices() into bootm_final() so it is available to all architectures. Drop the RISC-V weak definition and header declaration since the generic one in bootm.h is used instead.
