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

2026-02-25T01:47:03+00:00

Add support for EFI capsule updates via U-Boot's DFU. This flashes the
boot partition with the new image provided in the capsule.

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

2026-02-25T01:47:03+00:00

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.

board: samsung: exynos-mobile: enable OF_BOARD support

2026-02-23T06:35:33+00:00

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

2026-02-23T06:35:33+00:00

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.

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

2026-02-23T06:35:33+00:00

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.

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

2026-02-23T06:35:33+00:00

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.

treewide: Clean up DECLARE_GLOBAL_DATA_PTR usage

2026-02-17T19:50:22+00:00

Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and
drop the unnecessary inclusion of asm/global_data.h.

Headers should be included directly by the files that need them,
rather than indirectly via global_data.h.

arm: Update linker scripts to ensure appended device tree is aligned

2026-01-20T18:06:41+00:00

With commit 0535e46d55d7 ("scripts/dtc: Update to upstream version
v1.7.2-35-g52f07dcca47c") it is now a fatal error to U-Boot if our
device tree is not 8-byte aligned. In commit 85f586035d75 ("ARM: OMAP2+:
Pad SPL binary to 8-byte alignment before DTB") Beleswar Padhi explains
that we must have ALIGN(x) statements inside of a section to ensure that
padding is included and not simply that the linker address counter is
incremented. To that end, this patch:
- Expands some linker sections to be more readable when adding a second
  statement to the section.
- Aligns the final section before _end (for U-Boot) or
  _image_binary_end or __bss_end (for xPL phases) by 8-bytes by adding
  '. = ALIGN(8);' to the final section before the symbol.
- Ensure that we do have alignment by adding an ASSERT so that when not
  aligned we fail to link (and explain why).
- Remove now-spurious  '. = ALIGN(x);' statements that were intended to
  provide the above alignments.

kbuild: Bump the build system to 6.1

2026-01-02T16:28:14+00:00

Our last sync with the kernel was 5.1.

We are so out of sync now, that tracking the patches and backporting
them one by one makes little sense and it's going to take ages.

This is an attempt to sync up Makefiles to 6.1.
Unfortunately due to sheer amount of patches this is not easy to review,
but that's what we decided during a community call for the bump to 5.1,
so we are following the same guidelines here.
