kernels, so let's reflect that in the 32-bit ARM defconfigs.

ARM: orion: add ATAGS dependencies

Most of the remaining arm board files in the kernel are unused and will be
removed in early 2023 if no users step up. So far I got no user replies
about the orion5x and mv78xx0 machines, but these are still supported
in the default kernel of the Debian 'armel' (armv5 softfloat) distro,
and there is an active project on github that tries to keep some of
these machines working, and Mauri Sandberg is working on a DT conversion
for the D-Link DNS-323.

It appears the Debian-on-Buffalo project has not got the Terastation WXL
working in a few years, and the other mv78xx0 machines are just the
reference designs, so I assume none of these have remaining users.

For the Orion5x family, the same is probably true for its reference
implementations (RD88Fxxxxx, DB88F281) and the machines with less than
64MB of memory (WNR854T, WRT350N v2).

The remaining nine machines are now scheduled to be kept for at least
2023, hopefully to be replaced with DT based versions.

The mv78xx0_defconfig file needs to enable CONFIG_UNUSED_BOARD_FILES
to still build, while the other affected defconfig files lose the
specific boards.

ARM: defconfig: address renamed CONFIG_DEBUG_INFO=y

CONFIG_DEBUG_INFO is now implicitly selected if one picks one of the
explicit options that could be DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT,
DEBUG_INFO_DWARF4, DEBUG_INFO_DWARF5.

This was actually not what I had in mind when I suggested making
it a 'choice' statement, but it's too late to change again now,
and the Kconfig logic is more sensible in the new form.

Change any defconfig file that had CONFIG_DEBUG_INFO enabled
but did not pick DWARF4 or DWARF5 explicitly to now pick the toolchain
default.

ARM: refresh defconfig files

A lot of Kconfig options have changed over the years, and we tend
to not do a blind 'make defconfig' to refresh the files, to ensure
we catch options that should not have gone away.

I used some a bit of scripting to only rework the bits where an
option moved around in any of the defconfig files, without also
dropping any of the other lines, to make it clearer which options
we no longer have.

ARM: defconfig: use correct debug_ll settings

The debug-ll infrastructure can be configured in two ways, either
by selecting a platform specific debug option, or by picking one
of the generic options (8250 or pl01x typically). For compatibility
with multiplatform kernels, we have changed a couple of platforms
to use the former method now when they used to use the latter.

Unfortunately, this broke the defconfigs because now they still
enable CONFIG_DEBUG_LL_UART_PL01X or CONFIG_DEBUG_LL_UART_8250,
and we no longer configure the correct register addresses
automatically.

Embarrassingly, this was only found in linux-next when the
defconfig builds turned up errors for multiple people, and I
had not caught those in my own tests, which were done using
the randconfig fixes patchset on top, and that has a workaround
to avoid a build error when the addresses are not configured.

The error was something like:

.config:2010:warning: symbol value '' invalid for DEBUG_UART_PHYS
.config:2011:warning: symbol value '' invalid for DEBUG_UART_VIRT

This patch avoids the problem by removing the respective
statements from the defconfig files. Any out of tree defconfig
files on the platforms I have changed will have to do the same
change or run into the build error above. Any users that have
a full .config already set the correct DEBUG_UART_PHYS/VIRT
addresses and do not need to change anything.

kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.
