1e578ed20c sandbox: Add support for Address Sanitizer
Add CONFIG_ASAN to build with the Address Sanitizer. This only works
with the sandbox so the config is likewise dependent. The resulting
executable will have ASAN instrumentation, including the leak detector
that can be disabled with the ASAN_OPTIONS environment variable:

   ASAN_OPTIONS=detect_leaks=0 ./u-boot

Since u-boot uses its own dlmalloc, dynamic allocations aren't
automatically instrumented, but stack variables and globals are.

Instrumentation could be added to dlmalloc to poison and unpoison memory
as it is allocated and deallocated, and to introduce redzones between
allocations. Alternatively, the sandbox may be able to play games with
the system allocator and somehow still keep the required memory
abstraction. No effort to address dynamic allocation is made by this
patch.

The config is not yet enabled for any targets by default.

99e2fbcb69 linker_lists: Rename sections to remove . prefix
Rename the sections used to implement linker lists so they begin with
'__u_boot_list' rather than '.u_boot_list'. The double underscore at the
start is still distinct from the single underscore used by the symbol
names.

Having a '.' in the section names conflicts with clang's ASAN
instrumentation which tries to add redzones between the linker list
elements, causing expected accesses to fail. However, clang doesn't try
to add redzones to user sections, which are names with all alphanumeric
and underscore characters.

e844e5d908 sandbox: Move some mac addresses to device tree
This prevents some conflicts when running sandbox with -D, since the
"rom" mac address will be random and won't match the environment. We
still need to keep addresses for eth1 and eth6 in the environment,
because dm_test_eth_rotate expects to be able to disable them by
removing their envaddr variables. This can likely be fixed in a future
series by adding a function to cause sandbox eth_opts callback for a
particular mac to fail immediately.

bedb182e32 sandbox: net: Add aliases for ethernet devices
Commit f3dd213e15 ("net: introduce helpers to get PHY ofnode from MAC")
changed the ethernet sequence assignment from

uclass 36: ethernet
0   * eth@10002000 @ 05813460, seq 0
1   * eth@10003000 @ 05813550, seq 5
2   * sbe5 @ 05813640, seq 3
3   * eth@10004000 @ 05813730, seq 6
4   * dsa-test-eth @ 05813820, seq 4
5   * lan0 @ 05813a30, seq 2
6   * lan1 @ 05813b50, seq 7

to

uclass 36: ethernet
0   * eth@10002000 @ 03813630, seq 0
1   * eth@10003000 @ 03813720, seq 5
2   * sbe5 @ 03813810, seq 3
3   * eth@10004000 @ 03813900, seq 6
4     phy-test-eth @ 038139f0, seq 7

6   * lan0 @ 03813cf0, seq 2
7   * lan1 @ 03813e10, seq 8

This caused the mac address assignment to switch around. Avoid this in
the future by assigning aliases for all ethernet devices. This reverts
the sequence to what it was before the aformentioned commit (with
phy-test-eth as seq 8). There is no ethernet1 for whatever reason.

ccf24a9d77 sandbox: Avoid binman error when run without device tree
With sandbox, U-Boot can be run without a device tree (i.e. no -d or -T
parameter). In this case an empty device tree is created for convenience.
With a recent change this causes an error due to the missing '/binman'

be run without a device tree.

3609e1dc5f dts: automatically build necessary .dtb files
When building for a custom board, it is quite common to maintain a
private branch which include some defconfig and .dts files. But to
hook up those .dts files requires modifying a file "belonging" to
upstream U-Boot, the arch/*/dts/Makefile. Forward-porting that branch
to a newer upstream then often results in a conflict which, while it
is trivial to resolve by hand, makes it harder to have a CI do "try to
build our board against latest upstream".

The .config usually includes information on precisely what .dtb(s) are
needed, so to avoid having to modify the Makefile, simply add the
files in (SPL_)OF_LIST to dtb-y.

A technicality is that (SPL_)OF_LIST is not always defined, so rework
the Kconfig symbols so that (SPL_)OF_LIST is always defined (when
(SPL_)OF_CONTROL), but only prompted for in the cases which used to be
their "depends on".

nios2 and microblaze already have something like this in their
dts/Makefile, and the rationale in commit 41f59f6853 is similar to
the above. So this simply generalizes existing practice. Followup
patches could remove the logic in those two makefiles, just as there's
potential for moving some common boilerplate from all the
arch/*/dts/Makefile files to the new scripts/Makefile.dts.
