Merge tag 'v2025.04-rc4' into next
This uses Heinrich's merge of lib/efi_loader/efi_net.c which results in
no changes.
Unfortunately this change was not safe as some devices are bound before
relocation, but we don't want to probe them.
It causes 'raise: Signal # 8 caught' on jerry.
Move the bootstage timer to after autoprobe in initf_dm() since the
trace test does not tolerate any variance.

Rather than doing autoprobe within the driver model code, move it out to
the board-init code. This makes it clear that it is a separate step from
binding devices.
For now this is always done twice, before and after relocation, but we
should discuss whether it might be possible to drop the post-relocation
probe.
For boards with SPL, the autoprobe is still done there as well.
Note that with this change, autoprobe happens after the
EVT_DM_POST_INIT_R/F events are sent, rather than before.

Quite a few of the members of struct global_data are only used before
reloction, or have little meaning afterwards, yet they hang around in
struct global_data for the lifetime of U-Boot. This uses up precious
pre-relocation SRAM on many boards.
To help with this, start a new struct which exists only before
relocation. Move new_fdt into this new struct. Drop the display of it
in the 'bdinfo' command as it is probably not very useful.
Note that the field does not exist in SPL builds.

bootstage_get_size() returns the total size of the data structure
including associated records.
When copying from gd->bootstage, only the allocation size of gd->bootstage
must be used. Otherwise too much memory is copied.
This bug caused no harm so far because gd->new_bootstage is always
large enough and reading beyond the allocation length of gd->bootstage
caused no problem due to the U-Boot memory layout.
Fix by using the correct size and perform the initial copy directly
in bootstage_relocate() to have the whole relocation process in the
same function.

When U-Boot is running from flash memory (execute in place) then
gd->fdt_blob before relocation points to read-only flash memory.
So U-Boot calls board_fix_fdt() with read-only gd->fdt_blob pointer which
cause immediate CPU crash when callback is trying to modify gd->fdt_blob.
Fix this issue by introducing a new config option OF_INITIAL_DTB_READONLY
which moves fix_fdt callback after the reloc_fdt callback. This makes
CONFIG_OF_BOARD_FIXUP working also if U-Boot before relocation is not
running from read/write (S)RAM memory.
This is required for mpc85xx boards when booting from flash NOR.

Typically the bloblist is set up after the devicetree is present. This
makes sense because bloblist may use malloc() to allocate the space it
needs.
However sometimes the devicetree itself may be present in the bloblist.
In that case it is at a known location in memory so we can init the
bloblist very early, before devicetree.
Add a flag to indicate whether the bloblist has been inited. Add a
function to init it only if needed. Use that in the init sequence.

At present the initcall list consists of a list of function pointers. Over
time the initcall lists will likely change to mostly emitting events,
since most of the calls are board- or arch-specific.
As a first step, allow an initcall to be an event type instead of a
function pointer. Add the required macro and update initcall_run_list() to
emit an event in that case, or ignore it if events are not enabled.
The bottom 8 bits of the function pointer are used to hold the event type,
with the rest being all ones. This should avoid any collision, since
initcalls should not be above 0xffffff00 in memory.
Convert misc_init_f over to use this mechanism.
Add comments to the initcall header file while we are here. Also fix up
the trace test to handle the change.

At present this leaves the stack at the pre-relocation value. This is not
ideal since we want to have U-Boot running entirely from the top of
memory.
In addition, the new global_data pointer is not actually used, since
the global_data pointer itself is relocated, then the pre-relocation value
is changed, so the effective value (after relocation) does not update.
Adjust the implementation to follow the 32-bit code more closely, with a
trampoline function which is passed the new stack and global_data pointer.
This ensures that the correct values come through even when relocating.

In case of OF_SEPARATE (!OF_EMBED), the devicetree blob is placed

When GD_FLG_SKIP_RELOC is set, relocation is skipped, so the blob is
still in .bss section, but will be cleared. As a result, the devicetree
become invalid.
To avoid this issue, should relocate it regardless of GD_FLG_SKIP_RELOC
in reloc_fdt().
