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.

board: samsung: fix set_board_info() board_name buffer overflow

2026-04-13T23:42:34Z

Replace unbounded sprintf() with snprintf() using sizeof(info) as the bound when constructing the board_name string from bdname and bdtype. The previous call had no size limit and could overflow the 64-byte stack buffer if the concatenated string exceeded 63 bytes.

board: samsung: exynos-mobile: add EFI capsule update support

2026-02-25T01:47:03Z

Add support for EFI capsule updates via U-Boot's DFU. This flashes the boot partition with the new image provided in the capsule. Signed-off-by: Kaustabh Chakraborty Signed-off-by: Minkyu Kang

board: samsung: exynos-mobile: use blkmap for booting from userdata subpartitions

2026-02-25T01:47:03Z

Some distributions tend to provide a single combined image with EFS and the system root filesystem. Flashing it as-is in a single partition (usually done in userdata partition as it is the largest) is not bootable as U-Boot does not understand subpartitions. Use blkmap to map the userdata partition into its own block device. Signed-off-by: Kaustabh Chakraborty Signed-off-by: Minkyu Kang

board: samsung: exynos-mobile: enable OF_BOARD support

2026-02-23T06:35:33Z

OF_BOARD allows to choose the internal device tree in runtime. Use it to pass the external FDT as an internal one if it is not present. This approach is also used by qcom-phone, and it reduces boot image size. It is expected that an external FDT is present as U-Boot is packaged as an Android boot image.

board: samsung: exynos-mobile: disable MULTI_DTB_FIT support

2026-02-23T06:35:33Z

MULTI_DTB_FIT allowed a single U-Boot image to be booted in multiple devices, but it was not a scalable solution; as more devices are added, the U-Boot binary is bound to increase, space taken up by devicetrees which are not even used. The other approach is to be able to build separate images for multiple devices using the same "board" defined in U-Boot. This is used by qcom_phone to support muitiple devices. Follow the said approach for Exynos devices as well, disable MULTI_DTB_FIT for this board. Signed-off-by: Kaustabh Chakraborty Signed-off-by: Minkyu Kang

board: samsung: exynos-mobile: resolve env vars without board_info data

2026-02-23T06:35:33Z

Move environment variable setup procedure to exynos_env_setup(). This function is independent of data from exynos_board_info as it is due for removal in the succeding commits. Signed-off-by: Kaustabh Chakraborty Signed-off-by: Minkyu Kang

board: samsung: exynos-mobile: simplify parsing RAM banks from device tree

2026-02-23T06:35:33Z

Remove the baked-in bank addresses used for figuring out RAM banks from device tree. Instead, sequentially fill in the bank addresses and sizes, and doing away with an extra array for specifying bases. Signed-off-by: Kaustabh Chakraborty Signed-off-by: Minkyu Kang
