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.

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.

This patch adds a limited pulse-width modulator to sandbox's Chromium OS
Embedded Controller emulation. The emulated PWM device supports multiple
channels but can only set a duty cycle for each, as the actual EC
doesn't expose any functionality or information other than that. Though
the EC supports specifying the PWM channel by its type (e.g. display
backlight, keyboard backlight), this is not implemented in the emulation
as nothing in U-Boot uses this type specification.
This emulated PWM device is then used to test the Chromium OS PWM driver
in sandbox. Adding the required device node to the sandbox test

The signal handler is only useful for a few tests, as I understand it.
Make it optional.

Linux uses the prefix "ethernet" whereas u-boot uses "eth". This is from
the linux tree:
$ grep "eth[0-9].*=.*&" arch/**/*dts{,i}|wc -l
0
$ grep "ethernet[0-9].*=.*&" arch/**/*dts{,i}|wc -l
633
In u-boot device trees both prefixes are used. Until recently the only
user of the ethernet alias was the sandbox test device tree. This
changed with commit fc054d563b ("net: Introduce DSA class for Ethernet
switches"). There, the MAC addresses are inherited based on the devices
sequence IDs which is in turn given by the device tree.
Before there are more users in u-boot and both worlds will differ even
more, rename the alias prefix to "ethernet" to match the linux ones.
Also adapt the test cases and rename any old aliases in the u-boot
device trees.

os_find_text_base() assumes that first line of /proc/self/maps holds
information about the text. Hence we must call the function before calling
os_malloc() which calls mmap(0x10000000,).
Failure to do so has led to incorrect values for pc_reloc when an
exception was reported
=> exception undefined
Illegal instruction
pc = 0x5628d82e9d3c, pc_reloc = 0x5628c82e9d3c
as well as incorrect output of the bdinfo command
=> bdinfo

reloc off = 0x0000000010000000

In style of linked lists, instead of declaring symbols for boundaries
of getopt options array in the linker script, declare corresponding
sections and retrieve the boundaries via static inline functions.
Without this clang's LTO produces binary without any getopt options,
because for some reason it thinks that array is empty (start and end
symbols are at the same address).

Currently we use incremental linking (ld -r) to link several object
files from one directory into one built-in.o object file containing the
linked code from that directory (and its subdirectories).
Linux has, some time ago, moved to thin archives instead.
Thin archives are archives (.a) that do not really contain the object
files, only references to them.
Using thin archives instead of incremental linking
- saves disk space
- apparently works better with dead code elimination
- makes things easier for LTO
The third point is the important one for us. With incremental linking
there are several options how to do LTO, and that would unnecessarily
complicate things.
We have to use the --whole-archive/--no-whole-archive linking option
instead of --start-group/--end-group, otherwise linking may fail because
of unresolved symbols, or the resulting binary will be unusable.
We also need to use the P flag for ar, otherwise final linking may fail.

This commit does the same thing as Linux commit 33def8498fdd.
Use a more generic form for __section that requires quotes to avoid
complications with clang and gcc differences.
Remove the quote operator # from compiler_attributes.h __section macro.
Convert all unquoted __section(foo) uses to quoted __section("foo").
Also convert __attribute__((section("foo"))) uses to __section("foo")
even if the __attribute__ has multiple list entry forms.

This commit extends the sandbox to implement a dummy
extension_board_scan() function and enables the extension command in
the sandbox configuration. It then adds a test that checks the proper
functionality of the extension command by applying two Device Tree
overlays to the sandbox Device Tree.
