87c6f8a488 expo: Add basic implementation
An expo is a way of presenting and collecting information from the
user. It consists of a collection of 'scenes' of which only one is
presented at a time. An expo is typically used to show a boot menu
and allow settings to be changed.

One created, the same expo can be automatically presented in graphical
form using a vidconsole, or in text form on a serial console.

Add an initial implementation of the expo itself. Supports for scenes
and objects is provided later.

30f3333d88 image: Move common image code to image_board and command
We should use the cmd/ directory for commands rather than for common code
used elsewhere in U-Boot. Move the common 'source' code into
image-board.c to achieve this.

The image_source_script() function needs to call run_command_list()  so

519e6641db cmd: pxe_utils: Limit fdtcontroladdr usage to non-fitImage
Commit d5ba6188df ("cmd: pxe_utils: Check fdtcontroladdr in label_boot")
forces '$fdtcontroladdr' DT address as a third parameter of bootm command
even if the PXE transfer pulls in a fitImage which contains configuration
node with its own DT that is preferrable to be passed to Linux. Limit the
$fdtcontroladdr fallback utilization to non-fitImages, since it is highly
likely a fitImage would come with its own DT, while single-file images do
need a separate DT.

bcc85b96b5 cmd: source: Support specifying config name
As discussed previously [1,2], the source command is not safe to use with
verified boot unless there is a key with required = "images" (which has its
own problems). This is because if such a key is absent, signatures are
verified but not required. It is assumed that configuration nodes will
provide the signature. Because the source command does not use
configurations to determine the image to source, effectively no
verification takes place.

To address this, allow specifying configuration nodes. We use the same
syntax as the bootm command (helpfully provided for us by fit_parse_conf).
By default, we first try the default config and then the default image. To
force using a config, # must be present in the command (e.g. `source
$loadaddr#my-conf`). For convenience, the config may be omitted, just like
the address may be (e.g. `source \#`). This also works for images
(`source :` behaves exactly like `source` currently does).

If both timeout and prompt is set to 0 the default entry shall

a5dacef738 cmd: pxe: support INITRD and FDT selection with FIT
Since the commit d5ba6188df ("cmd: pxe_utils: Check fdtcontroladdr
in label_boot") the FDT or the FDTDIR label is required in extlinux.conf
and the fallback done by bootm command when only the device tree present
in this command parameters is no more performed when FIT is used for
kernel.

When the label FDT or FDTDIR are absent or if the device tree file is
absent, the PXE command in U-Boot uses the default U-Boot device tree
selected by fdtcontroladdr = gd->fdt_blob, it is the "Scenario 3".

With this scenario the bootm FIP fallback is no more possible with
the extlinux.conf when only "kernel" label is present and is a FIP:

  kernel <path>#<conf>[#<extra-conf[#...]]

As the U-Boot FDT is always provided in the third bootm argument,
the device tree found in FIP is not used as fallback, it was done
previously in boot_get_fdt().

This patch adds a new field kernel_label to save the full kernel label.
The FDT bootm parameters use the kernel address (to avoid to load a
second time the same FIP) and the config when this full label is reused
for "fdt" or "initrd" label.

This FIP support in extlinux.conf is restored when the "FDT" label
can be found and select the same FIP (identical file and configuration):

  kernel <path>#<conf>[#<extra-conf[#...]]
  fdt <path>#<conf>[#<extra-conf[#...]]

The patch add also this possibility for initrd.

  initrd <path>#<conf>[#<extra-conf[#...]]

2827c2f07d Fix usage of CONFIG_PREBOOT
Due to usage of PREBOOT in Kconfig, macro CONFIG_PREBOOT is always defined
when CONFIG_USE_PREBOOT is enabled. In case CONFIG_PREBOOT is not
explicitly enabled it is set to empty C string and therefore
'#ifdef CONFIG_PREBOOT' guard does not work. Fix this issue by introducing
a new Kconfig symbol PREBOOT_DEFINED which cause to define new C macro
CONFIG_PREBOOT_DEFINED only when CONFIG_PREBOOT is really defined.

Change usage of '#ifdef CONFIG_PREBOOT' by '#ifdef CONFIG_USE_PREBOOT' for
code which checks if preboot code would be called and by
'#ifdef CONFIG_PREBOOT_DEFINED' for defining preboot code.

73ceadcd72 Merge branch 'master' of https://source.denx.de/u-boot/custodians/u-boot-sunxi
Beside some rather unexciting sync of the DTs from the kernel tree, and
some Kconfig cleanup, there are some improvements for the ARMv5 Allwinner
family, to support boards with the F1C200s (64MB DRAM) better. We will
get actual board support as soon as the DTs have passed the Linux review
process.
There is also support for the X96 Mate TV Box, featuring the H616 SoC and
a full 4GB of DRAM.
Also we found the secret to enable SPI booting on the H616 (pin PC5 must
be pulled to GND), so the SPI boot support patch is now good to go.

Passed the gitlab CI, plus briefly tested on Pine64-LTS, LicheePi Nano,
X96 Mate and OrangePi Zero.

1bf98bd4e2 sunxi: Kconfig: introduce SUNXI_MINIMUM_DRAM_MB
Traditionally we assumed that every Allwinner board would come with at
least 256 MB of DRAM, and set our DRAM layout accordingly. This affected
both the default load addresses, but also U-Boot's own address
expectations (like being loaded at 160 MB).

Some SoCs come with co-packaged DRAM, but only provide 32 or 64MB. So
far we special-cased those *chips*, as there was only one chip per DRAM
size. However new chips force us to take a more general approach.

Introduce a Kconfig symbol, which provides the minimum DRAM size of the
board. If nothing else is specified, we use 256 MB, and default to
smaller values for those co-packaged SoCs.
Then select the different DRAM maps according to this new symbol, so
that different SoCs with the same DRAM size can share those definitions.

Inspired by an idea from Icenowy.

This is just refactoring: compiled for all boards before and after this
patch: the binaries were identical.

19511935df boot: Correct handling of addresses in boot_relocate_fdt()
This code uses casts between addresses and pointers, so does not work with
sandbox. Update it so we can allow sandbox to do device tree fixups.

13819f07ea bootm: Change incorrect 'unsupported' error
At present when bootm fails, it says:

    subcommand not supported

and then prints help for the bootm command. This is not very useful, since
generally the error is related to something else, such as fixups failing.
It is quite confusing to see this in a test run.

Change the error and show the error code.

We could update the OS functions to return -ENOSYS when they do not
support the bootm subcommand. But this involves some thought since this is
arch-specific code and proper errno error codes are not always returned.
Also, with the code as is, all required subcommands are of course
supported - a problem would only come if someone added a new one or
removed support for one from an existing OS. Therefore it seems better to
leave that sort of effort for when our bootm tests are improved.

Note: v1 of this patch generated a discussion[1] about printing error
strings automatically using printf(). That is outside the scope of this
patch but will be dealt with separately.

28a22cd9a4 bootstd: Fix listing boot devices
bootdev_list() uses uclass_*_device_err() to iterate devices.
However, the only value _err adds is returning an error when the device
pointer is null, and that's checked anyway.

Also there is some intent to report errors, and that's what
uclass_*_device_check() is for, use it.
