Rasmus Villemoes <rv@rasmusvillemoes.dk> says:
The commit message for patch 1 explains what it is I'd like to be able
to do, but here's some more background:
For a long time, we've embedded the boot script in the U-Boot binary
by building a bootscript.itb, and using a .dtsi like
/ {
config {
bootscript = /incbin/("/path/to/bootscript.itb");
};
};
which in turn is mentioned in CONFIG_DEVICE_TREE_INCLUDES, that
bootscript.itb FIT image has been embedded in U-Boot's control
dtb. Running that was then a matter of doing
fdt addr ${fdtcontroladdr} && fdt get addr bsaddr /config bootscript && source ${bsaddr}
There are a couple of advantage of having the bootscript (and other
script logic) embedded in the U-Boot binary. First, there's no need to
figure out some separate partition to store the script in, and making
sure that gets updated whenever the bootloader itself does. Second,
one doesn't need to worry about verifying the script; whatever steps
one needs to take to implement secure boot for U-Boot itself will by
necessity also cover the control dtb (if nothing else then because
that's where the public key for the kernel verification lives). And
third, the boot script is automatically updated together with U-Boot
itself; and if U-Boot is stored in an eMMC boot partition, that update
is guaranteed to be atomic.
Now with the stricter requirements of libfdt starting from v2026.04,
the above command no longer worked, or only half the time, because the
embedded FIT image may not land on an 8-byte aligned address. So that
line had to be changed a little (line breaks added)
fdt addr ${fdtcontroladdr}
&& fdt get addr bsaddr /config bootscript
&& fdt get size bssize /config bootscript
&& cp.b ${bsaddr} ${loadaddr} ${bssize}
&& source ${loadaddr}
which is getting quite unwieldy.
Then it struck me that one could perhaps simplify all of this quite a
lot: Cut out the intermediate bootscript.itb, just create a .dtsi
which directly puts a /images node inside the control dtb
/ {
images {
default = "bootscript";
bootscript {
description = "Boot script";
data = /incbin/("/path/to/bootscript.sh");
type = "script";
compression = "none";
};
};
};
and treat the control dtb itself as a FIT image; so the command to put
in $bootcmd becomes simply
source ${fdtcontroladdr}:bootscript
and embedding other pieces of callable scripts is quite trivial.
And that almost works out-of-the-box, except for the fit_check_format() sanity check.
Introduce a CONFIG_ knob that allows one to opt out of those sanity
checks, for the special case of the address being checked being
identical to gd->fdt_blob.
Link: https://lore.kernel.org/r/20260602213013.558064-1-rv@rasmusvillemoes.dk
Add a test demonstrating how one can embed various scripts in the
control DTB.
Verify that the source command can be used with ${fdtcontroladdr} by
itself (invoking the default script), and with :<node-name>
suffix. Check that the scripts themselves can invoke "sibling"
scripts. Also verify that without CONTROL_DTB_AS_FIT set, the control
DTB is not accepted by the source command.

__FUNCTION__ and __PRETTY_FUNCTION__ are gcc extensions that predate
the C99 __func__ identifier. scripts/checkpatch.pl emits a warning
for any new use of __FUNCTION__ and recommends __func__ instead. In
C (unlike C++) __PRETTY_FUNCTION__ is identical to __func__ because
C function names do not carry signature information, so the
distinction has no behavioural effect here. The majority of the tree
already uses __func__, but a handful of older files in arch/, board/,
boot/, drivers/, examples/ and include/ still carry the gcc spellings
(55 occurrences of __FUNCTION__ across 19 files plus one
__PRETTY_FUNCTION__ in drivers/usb/musb-new/omap2430.c). Convert
them all to the C99 form so the tree is consistent and new patches
in these areas do not have to follow an outdated local style.
Ten "Unnecessary ftrace-like logging - prefer using ftrace" warnings
remain on the printf("%s\n", __func__) and dbg("%s\n", __func__)
function-entry traces in drivers/net/rtl8169.c (behind DEBUG_RTL8169*
preprocessor guards) and drivers/usb/host/ohci-hcd.c. checkpatch
matches the literal "%s\n", __func__ shape regardless of the wrapper,
so silencing those warnings would require changing the debug message
text or removing the traces entirely.

Add a sandbox reset controller compatible string
"sandbox,reset-ctl-fallback-only" that reuses the existing sandbox assert,

Extend the reset-ctl-test DT node with a fifth reset line named "fallback"
that points at the new provider, and add dm_test_reset_reset_fallback_path
which verifies sandbox_reset_get_count() stays zero (rst_reset is never
invoked) while the line ends deasserted after reset_reset().
This complements the existing rst_reset coverage on sandbox,reset-ctl and
