When we first added ARM support to coreboot, it was clear that the
bootblock would need to do vastly different tasks than on x86, so we
moved its main logic under arch/. Now that we have several more
architectures, it turns out (as with so many things lately) that x86 is
really the odd one out, and all the others are trying to do pretty much
the same thing. This has already caused maintenance issues as the ARM32
bootblock developed and less-mature architectures were left behind with
old cruft.
This patch tries to address that problem by centralizing that logic
under lib/ for use by all architectures/SoCs that don't explicitly
opt-out (with the slightly adapted existing BOOTBLOCK_CUSTOM option).
This works great out of the box for ARM32 and ARM64. It could probably
be easily applied to MIPS and RISCV as well, but I don't have any of
those boards to test so I'll mark them as BOOTBLOCK_CUSTOM for now and
leave that for later cleanup.

It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.
This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.
However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.
util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

On most platforms, enabling the console and exception handlers are
amongst the very first things you want to do, as they help you see
what's going on and debug errors in other early init code. However, most
ARM boards require some small amount of board-specific initialization
(pinmuxing, maybe clocks) to get the UART running, which is why
bootblock_mainboard_init() (and with it almost all of the actual
bootblock code) always had to run before console initialization for now.
This patch introduces an explicit bootblock_mainboard_early_init() hook
for only that part of initialization that absolutely needs to run before
console output. The other two hooks for SoC and mainboard are moved
below console_init(). This model has already proven its worth before in
the tegra124 and tegra132 custom bootblocks.

The following patches had to be squashed
to properly build all the different ARM boards.
ipq8064: storm: re-arrange bootblock initialization
The recent addition of the storm bootblock initialization broke
compilation of Exynos platforms. The SOC specific code needs to be
kept in the respective source files, not in the common CPU code.
As of now coreboot does not provide a separate SOC initialization API.
In general it makes sense to invoke SOC initialization from the board
initialization code, as the board knows what SOC it is running on.
Presently all what's need initialization on 8064 is the timer. This
patch adds the SOC initialization framework for 8064 and moves there
the related code.

. nyan_big, peach_pit, and storm targets build fine now.

arm: Redesign mainboard and SoC hooks for bootblock
This patch makes some slight changes to the way bootblock_cpu_init() and
bootblock_mainboard_init() are used on ARM. Experience has shown that
nearly every board needs either one or both of these hooks, so having
explicit Kconfigs for them has become unwieldy. Instead, this patch
implements them as a weak symbol that can be overridden by mainboard/SoC
code, as the more recent arm64_soc_init() is also doing.
Since the whole concept of a single "CPU" on ARM systems has kinda died
out, rename bootblock_cpu_init() to bootblock_soc_init(). (This had
already been done on Storm/ipq806x, which is now adjusted to directly
use the generic hook.) Also add a proper license header to
bootblock_common.h that was somehow missing.
Leaving non-ARM32 architectures out for now, since they are still using
the really old and weird x86 model of directly including a file. These
architectures should also eventually be aligned with the cleaner ARM32
model as they mature.

TEST=Booted on Pinky. Compiled for Storm and confirmed in the
disassembly that bootblock_soc_init() is still compiled in and called
right before the (now no-op) bootblock_mainboard_init().

There are ARM systems which are essentially heterogeneous multicores where
some cores implement a different ARM architecture version than other cores. A
specific example is the tegra124 which boots on an ARMv4 coprocessor while
most code, including most of the firmware, runs on the main ARMv7 core. To
support SOCs like this, the plan is to generalize the ARM architecture so that
all versions are available, and an SOC/CPU can then select what architecture
variant should be used for each component of the firmware; bootblock,
romstage, and ramstage.

ARM: Split out ARMv7 code and make it possible to have other arch versions.
We don't always want to use ARMv7 code when building for ARM, so we should
separate out the ARMv7 code so it can be excluded, and also make it possible
to include code for some other version of the architecture instead, all per
build component for cases where we need more than one architecture version
at a time.
The tegra124 bootblock will ultimately need to be ARMv4, but until we have
some ARMv4 code to switch over to we can leave it set to ARMv7.
