Quite a lot of the code in common/relates to booting and images. Before
adding more it seems like a good time to move the code into its own
directory.
Most files with 'boot' or 'image' in them are moved, except:
- autoboot.c which relates to U-Boot automatically running a script
- bootstage.c which relates to U-Boot timing
Drop the removal of boot* files from the output directory, since this
interfers with the symlinks created by tools and there does not appear
to be any such file from my brief testing.

The optee_copy_fdt_nodes is only used to copy op-tee nodes
of U-Boot device tree (from gd->fdt_blob when OF_LIVE is not activated)
to external device tree but it is not compatible with OF_LIVE.
This patch migrates all used function fdt_ functions to read node on
old_blob to ofnode functions, compatible with OF_LIVE and remove this
parameter "old_blob".
The generated "device tree" is checked on stm32mp platform with OF_LIVE

At present this function does not accept a size for the FIT. This means
that it must be read from the FIT itself, introducing potential security
risk. Update the function to include a size parameter, which can be
invalid, in which case fit_check_format() calculates it.
For now no callers pass the size, but this can be updated later.
Also adjust the return value to an error code so that all the different
types of problems can be distinguished by the user.

The loading convention for optee or any other tee on arm64 is as bl32
parameter to the trusted-firmware. So TF-A gets invoked with the TEE as
bl32 and main u-boot as bl33. Once it has done its startup TF-A jumps
into the bl32 for the TEE startup, returns to TF-A and then jumps to bl33.
All of them get passed a devicetree as parameter and all components often
get loaded from a FIT image.
OP-TEE will create additional nodes in that devicetree namely a firmware
node and possibly multiple reserved-memory nodes.
While this devicetree is used in main u-boot, in most cases it won't be
the one passed to the actual kernel. Instead most boot commands will load
a new devicetree from somewhere like mass storage of the network, so if
that happens u-boot should transfer the optee nodes to that new devicetree.
To make that happen introduce optee_copy_fdt_nodes() called from the dt
setup function in image-fdt which after checking for the optee presence
in the u-boot dt will make sure a optee node is present in the kernel dt
and transfer any reserved-memory regions it can find.

Refactoring for boot_get_fdt()

Our platform doesn't store the DTB into the Android image second area,
but rather copies the DTB to RAM from a dedicated dtb.img partition [0],
prior to booting the Android image by calling bootm.
Similar to [1], we find it useful to just call 'bootm' and have the
right DTB being passed to OS (assuming its address has been previously
stored in 'fdtaddr' by calling `fdt addr <dtb-addr>`).
Booting Android with DTB from 'fdtaddr' will only occur if:
- No DTB is embedded in the second area of Android image
- 'fdtaddr' points to a valid DTB in RAM

The 'no_fdt' goto label was introduced by v2015.01 commit [0] and it
had two review stages [1-2]. The *documented* purpose behind commit [0]
is (excerpt from commit description):
> allows both FDT and non-FDT kernels to boot by making the
> third parameter to the bootm/bootz optional
While [1] and [2] share the same goal, they have very different
implementations:
- [1] was based on a very simple 'argc' check at function error out
with returning success to the caller if the third parameter was NOT
passed to bootm/bootz command. This approach had the downside of
returning success to the caller even in case of legitimate internal
errors, which should halt booting.
- [2] added the "no_fdt" label and several "goto no_fdt" statements.
This allowed to report the legitimate internal errors to the caller.
IOW the major difference between [1] and [2] is:
- [1] boot w/o FDT if FDT address is not passed to boot{m,z,*}
- [2] give *freedom* to the developer to boot w/o FDT from any
(more or less) arbitrary point in the function flow (and here
comes the peculiar aspect, which looks to be a leftover from [1])
with the precondition that the 3rd argument (FDT address) is NOT
provided to boot{m,z,*}. In practice, this means that only a subset
of "goto no_fdt" end up booting w/o FDT while the other subset is
returning an error to the caller.
This patch removes the peculiar behavior described above, such that
"goto no_fdt" performs really what it tells to the developer.
The motivation of this patch is to decrease the unneeded complexity
and increase the readability of boot_get_fdt().

Paranoid programming [1] lies at the foundation of proper software
development, but the repetitive zeroing-out of output arguments in the
context of the same function rather clutters the code and inhibits
further refactoring/optimization than is doing any good.
In boot_get_fdt(), we already perform zero/NULL-initialization of
*of_flat_tree and *of_size at the beginning of the function, so doing
the same at function error-out is redundant/superfluous.
Moreover, keeping the code unchanged might encourage the developers to
update *of_flat_tree and *of_size during some interim computations,
which is against the current design of boot_get_fdt(). Currently,
writing useful data into these arguments happens just before
successfully returning from boot_get_fdt() and it should better stay so.

It works perfectly fine to boot an Android boot.img with bootm command
followed by an explicit address argument that holds the image. But if
we have boot.img downloaded into default 'loadaddr', and then boot it
using bootm command without the address argument, we will run into
problem, because U-Boot fails to find ramdisk and fdt (second area) in
boot.img.
The current Android image support assumes there is always an address
argument on bootm command. However just like booting any other images,
'loadaddr' should be used when address argument is missing from bootm
command. It patches boot_get_ramdisk() and boot_get_fdt() a bit to
support this quite common usage of bootm command for Android image.

When running sandbox with the new pointer sanitization we just recently
introduced, we're running into a case with FIT images where we end up
interpreting pointers as addresses.
What happened is that most callers of set_working_fdt_addr() simply
convert pointers into addresses without taking into account that they
might be 2 separate address spaces. Fix the callers up to map their
pointers into addresses.
This makes sandbox tests pass for me again.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.
