Several different firmware users have repetitive code to extract the
firmware data from a FIT. Add some helper functions to reduce the amount
of repetition. fit_conf_get_prop_node (eventually) calls
fdt_check_node_offset_, so we can avoid an explicit if. In general, this
version avoids printing on error because the callers are typically
library functions, and because the FIT code generally has (debug)
prints of its own. One difference in these helpers is that they use
fit_image_get_data_and_size instead of fit_image_get_data, as the former
handles external data correctly.

Signed-off-by: Simon Glass <sjg@chromium.org>
At present there is a confusing array of functions that handle the
device tree fix-ups needed for booting an OS. We should be able to switch
to using events to clean this up.
As a first step, create a new event type and call it from the standard
place.
Note that this event uses the ofnode interface only, since this can
support live tree which is more efficient when making lots of updates.

This was a work-around for the fact that global bootmeths such as EFI
bootmgr and VBE don't use a particular bootdev, or at least select it
themselves so that we don't need to scan all bootdevs when using that
bootmeth.
Drop the system bootdev entirely.
Signed-off-by: Simon Glass <sjg@chromium.org>
Now that we can separate this out from the normal bootmeths, update the
code to create it always.
We cannot rely on the device tree to create this, since the EFI project

with its processing.
Signed-off-by: Simon Glass <sjg@chromium.org>
Typically we want to find and use global bootmeths first, since they have
the best idea of how the system should boot. We then use normal bootmeths
as a fallback.
Add the logic for this, putting global bootmeths at the end of the
ordering. We can then easily scan the global bootmeths first, then drop
them from the list for subsequent bootdev-centric scans.
This changes the ordering of global bootmeths, so update the
bootflow_system() accordingly.
Drop the comment from bootmeth_setup_iter_order() since this is an
exported function and it should be in the header file.

For most testing we don't want this bootmeth to actually do anything. For

for this test.
Signed-off-by: Simon Glass <sjg@chromium.org>
The current way of handling things like EFI bootmgr is a bit odd, since
that bootmeth handles selection of the bootdev itself. VBE needs to work
the same way, so we should support it properly.
Add a flag that indicates that the bootmeth is global, rather than being
invoked on each bootdev. Provide a helper to read a bootflow from the
bootmeth.

Linux determines its console based on several sources:
1. the console command line parameter
2. device tree (e.g. /chosen/stdout-path)
3. various other board- and arch-specific sources
If the console parameter specifies a real console (e.g. ttyS0) then that is
used as /dev/console. However, if it does not specify a real console (e.g.
ttyDoesntExist) then *nothing* will be used as /dev/console.
Reading/writing it will return ENODEV. Additionally, no other source will
be used as a console source.
Linux commit ab4af56ae250 ("printk/console: Allow to disable console output
by using console="" or console=null") recently changed the semantics of the
parameter. Previously, specifying console="" would be treated like
specifying some other bad console. This commit changed things so that it
added /dev/ttynull as a console (if available). However, it also allows
for other console sources. If the device tree specifies a console (such as
if U-Boot and Linux share a device tree), then it will be used in addition
to /dev/ttynull. This can result in a non-silent console.
To avoid this, explicitly set ttynull as the console. This will disable
other console sources. If CONFIG_NULL_TTY is disabled, then this will have
the same behavior as in the past (no output, and writing /dev/console
returns ENODEV).
