EFI has a Boot Graphics Record Table which can be used to show a logo
when booting up and shutting down.
Add support for adding this to the image, using a U-Boot logo which
includes the name, since many people will be unfamiliar with the logo.
Signed-off-by: Simon Glass <sjg@chromium.org>
This rule assumes that any .bmp file relates to the logo. We want to be
able to add a second BMP in some cases, so update the rule to match
a filename ending in '_logo.bmp'

Sometimes it is useful to provide several disks to QEMU. Update the -d

Sometimes it is useful to use SCSI instead of the plain virtio. Add a

Drop the -S for --sct-seq since it is a less common option.

We want to use the -K option for providing a kernel via QEMU's QFW

It seems better to specify the arch rather than using somewhat cryptic
flags. The build-qemu scripts uses -a (for Architecture) so do the same

This is not really needed, since it is the default and we have -p to

Plumb in the ability for U-Boot proper to accept an incoming standard
passage from a previous phase, such as SPL or TF-A. This allows data to
be passed from binary to binary when firmware is booting.
Series-changes: 2
- Rebase to master
- Rework global_data for new stdpass convention
Series-changes: 3
- Move passage.h into this patch
- Add passage_valid() to decide if stdpass was provided
- Move arch_passage_entry() into this patch
- Make the global_data fields present only when needed

commit ddf67daac3 ("efi_capsule: Move signature from DTB to .rodata")
was reverted in
commit 47a25e81d3 ("Revert "efi_capsule: Move signature from DTB to .rodata"")
because that's what U-Boot was usually doing -- using the DT to store
configuration and data. Some of the discussions can be found here [0].
(Ab)using the device tree to store random data isn't ideal though.
On top of that with new features introduced over the years, keeping
the certificates in the DT has proven to be problematic.
One of the reasons is that platforms might send U-Boot a DTB
from the previous stage loader using a transfer list which won't contain
the signatures since other loaders are not aware of internal
U-Boot ABIs. On top of that QEMU creates the DTB on the fly, so adding
the capsule certificate there does not work and requires users to dump
it and re-create it injecting the public keys.
Now that we have proper memory permissions for arm64, move the certificate
to .rodata and read it from there.

Convert this to Python and make use of the build_helpers module. Update
that module to remove old options and improve the ordering of options.
The script doubles in size, part of which is being a lot more friendly
with virtiofsd problems, as well as adding a verbose mode.
Update the documentation as well.

Recent Ubuntu versions (24.04+) disallow pip by default when
installing packages. The recommended approach is to use a virtual
environment (venv) instead.
Because of this, "make pip" is failing on such versions.
To prepare CI container migration to Ubuntu 24.04, use a venv in the
make_pip script.

It is confusing to have both "$(PHASE_)" and "$(XPL_)" be used in our
Makefiles as part of the macros to determine when to do something in our
Makefiles based on what phase of the build we are in. For consistency,
bring this down to a single macro and use "$(PHASE_)" only.

This is a feeble attempt to update the qemu script to run a selection of
UEFI tests. It copies a .seq file into the disk so it can be read by
SCT.
It doesn't seem to work and I am not sure why. I am posting it in case
someone else has ideas or wants to pic it up.
Once Ilias' CI solution is in place, I can perhaps come back to this.

It is handy to be able to quickly build and boot a QEMU image for a

For distros it only supports Ubuntu. Both 32- and 64-bit builds are

of SWIG_Python_AppendOutput, which would require an extra parameter

- Switch to using upstream DT on DH i.MX8MP DHCOM PDK2/PDK3.
- Add ability to build fallback DTBOs from arch/$(ARCH)/dts.
- Remove fdt_high and initrd_high env variables from imx6-dhcom.
- Add dummy clk for imx8.
- Fix DT corruption in imx8_cpu.
- Improve DDR stability on pico-imx7d.
Currently the enablement of OF_UPSTREAM results on the build system
searching for DTs only in dts/upstream/ . There are platforms which
use U-Boot specific DTBOs applied on top of U-Boot control DT during
SPL stage, and source DTs for these are located in arch/$(ARCH)/dtb.
Add dedicated 'dtbos' target which builds only .dtbos and not .dtbs and
in case CONFIG_OF_UPSTREAM_INCLUDE_LOCAL_FALLBACK_DTBOS is enabled, build
this target for arch/$(ARCH)/dtb to generate local U-Boot specific DTBOs.
Adjust top level Makefile so binman would search for .dtb and .dtbo in
both OF_UPSTREAM specific paths and arch/$(ARCH)/dtb for the .dtbo case
in case CONFIG_OF_UPSTREAM_INCLUDE_LOCAL_FALLBACK_DTBOS is enabled.
