After commit 63e54275f684 (libpayload: Implement new CBFS access API),
libpayload includes headers from commonlib/bsd, which in turn include
vb2_sha.h from vboot after commit 0655f78041ef (commonlib/bsd: Add new
CBFS core implementation). Usually submodules are initialized by the top
level Makefile.inc, but since this file is never read when building
libpayload based payloads outside the main coreboot build, the header
cannot be found unless the vboot submodule had previously been
initialized. This is especially evident when following Tutorial 1 in the
documentation, where the coreboot repo is cloned without recursing into
submodules and coreinfo is built separately from the coreboot build
using `make -C payloads/coreinfo`.
TEST=Deinitialize submodules and run `make -C payloads/coreinfo`.
Coreinfo should build without error.

This patch contains several minor cleanups related to compiler.h:
- Replace __always_unused() (which is a Linux-specific concept that
doesn't make sense without also having __maybe_unused(), and had zero
uses in the codebase) with __unused() which moves here from helpers.h
- Add __underscores__ to the names of all attributes in the compiler
attribute shorthand macros. This is necessary to make them work in
files where the same name was already used for an identifier (e.g.
cbfstool/cbfs.h's `unused` array of file types).
- Remove libpayload's own copy of compiler.h and make it directly pull
in the commonlib/bsd copy.

Don't assume that libpayload is built from a fully checked
out coreboot tree.
There's already an override when building vboot, so reuse
that override when referring to its header files.

llvm-ar does not support "open" script command, and fails with an error.
This patch fixes it by removing lines `$(AR) rc <object-files>` and
it puts them as "addmod" commands. This way all object files and
archives can be packed into one archive.

New CBFS API uses commonlib/bsd/cbfs_serialized.h, which includes
vboot's vb2_sha.h. And, because vboot's includes are not available
in libpayload's installation directory nor in lpgcc paths, it was
causing compilation errors. This patch fixes this issue.
lpgcc will look for `vboot` directory like it is doing for `include`
directory to create correct paths. However, if payload will be built
using libpayload's build dir as a base, then vboot headers from
3rdparty/vboot will be used, as there is no way to pass VBOOT_SOURCE
from makefile to lpgcc.
Moreover, this patch moves VBOOT_SOURCE to the main Makefile to
make it available for installation target, to install headers from
vboot directory provided by caller.

Mock architecture can be used to build libpayload using host compiler.
It can be enabled by setting ARCH_MOCK=y in the dotconfig. It sets
LITTLE_ENDIAN=y, as most machines these days use little-endian CPUs.
Libpayload will use HOSTCC as CC, HOSTLD as LD, etc. instead of tools
provided by xcompile.
Mock architecture configuration can be used by payloads for testing
purposes. Thanks to it, tests can be architecture-independent,
and can be executed without requiring compatible Kconfig options,
e.g. ARCH_ARM64=y for ARM64 machine. However, one has to provide
implementation for most architecture-specific functions present
in arch/* directories.

Headers in libpayload define various structs like so:
struct struct_name { ... } __packed;
However, these header files do not include the compiler.h macro that
defines what __packed is, so they are actually defining a variable named
__packed and *not* declaring a packed struct. This leads to defining the
same variable multiple times, which was caught by GCC 10. Add compiler.h
to the compiler parameters so it is included in all files automatically.

Link time optimization is a technique for whole-program optimization.
Instead of doing code generation during compilation, the compiler saves
its intermediate representation to the object files. During the final
linking step, it will then merge all the object files together and
perform optimizations on the entire program. This can often reduce the
final binary size, but also may increase the total compilation time.
This patch introduces a Kconfig option for enabling link time
optimization in libpayload. Since libpayload does no linking of its own,
its LTO archive files will contain only IR and no generated code.
Downstream projects will need to use LTO-aware tools when manipulating
the archives (eg. gcc-ar and gcc-nm), but otherwise do not need to use
LTO themselves -- the compiler will recognize which files are LTO and
which are not, so enabling this option should mostly be "drop in".
For example, when building coreinfo.elf using tinycurses libpayload:
binary size compilation time
default 114 KiB 11.49s
LTO 95 KiB 10.36s
In this case the total compilation time was actually shorter -- despite
the final linking step taking longer, this was offset by the shorter
compilation times for each individual file (since there is no code gen
until the very end).

This patch adds support for the LZ4 decompression algorithm to
libpayload. It's what all the cool kids are using for decompression
these days and has many interesting advantages over LZMA (and everything
else I know of): blazing fast decompression (20(!) times faster than
LZMA, twice as fast as LZO on my Cortex-A72), no memory requirements on
decompression, and possibly in-place decompression support. It pays for
that with a lower compression ratio (about 50% larger compressed size
than LZMA, 10% larger than LZO for an ARM64 Linux kernel binary), but
the boot time math still works in its favor for our IO speeds.
This patch only adds the raw decompression functions for use by external
payloads, we can later try integrating them in CBFS. It copies the
decompression code itself unmodified from the upstream LZ4 library at
github.com/Cyan4973/lz4 which will hopefully make it easy to update. The
frame format parsing is reimplemented since the upstream version looks
unnecessarily complex and unreadable for our needs.

This patch adds the ability to attach a GDB host through the UART to a
running payload. Libpayload implements a small stub that can parse and
respond to the GDB remote protocol and provide the required primitives
(reading/writing registers/memory, etc.) to allow GDB to control
execution.
The goal of this implementation is to be as small and uninvasive as
possible. It implements only the minimum amount of primitives required,
and relies on GDB's impressive workaround capabilities (such as
emulating breakpoints by temporarily replacing instructions) for the
more complicated features. This way, a relatively tiny amount of code on
the firmware side opens a vast range of capabilities to the user, not
just in debugging but also in remote-controlling the firmware to change
its behavior (e.g. through GDBs ability to modify variables and call
functions).
By default, a system with the REMOTEGDB Kconfig will only trap into GDB
when executing halt() (including the calls from die_if(), assert(), and
exception handlers). In addition, payloads can manually call gdb_enter()
if desired. It will print a final "Ready for GDB connection." on the
serial, detach the normal serial output driver and wait for the commands
that GDB starts sending on attach.
Based on original implementation by Gabe Black <gabeblack@chromium.org>.
BUG=chrome-os-partner:18390
TEST=Boot a GDB enabled image in recovery mode (or get it to hit a
halt()), close your terminal, execute '<toolchain>-gdb --symbols
/build/<board>/firmware/depthcharge_gdb/depthcharge.elf --directory
~/trunk/src/third_party/coreboot/payloads/libpayload --directory
~/trunk/src/platform/depthcharge --directory
~/trunk/src/platform/vboot_reference --ex "target remote
<cpu_uart_pty>"' and behold the magic.
(You can also SIGSTOP your terminal's parent shell and the terminal
itself, and SIGCONT them in reverse order after GDB exits. More
convenient wrapper tools to do all this automatically coming soon.)

Pass -ggdb3 to the compiler when building libpayload, -ggdb so that it uses
"the most expressive format available", and 3 so that the debugging level is
set to 3, the highest value currently supported. The debugging information can
be stripped by the payload consuming the library, and will definitely be
stripped by cbfstool when installing that payload into an image.

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.

This target does (pretty much) exactly the same what jenkins
is doing on our build nodes:
- complete abuild run of our tree with a given payload
- building all libpayload configs we ship
- building the cbmem utility
In fact at some point we could tell jenkins to just run this command.
For debugging, pass along V and Q variables so inner make processes
are slightly more noisy on demand.

When libpayload header files are included in the payload itself, it's possible
that the payloads config settings will conflict with the ones in libpayload.
It's also possible for the libpayload config settings to conflict with the
payloads. To avoid that, the libpayload config settings have _LP_ (for
libpayload) added to them. The symbols themselves as defined in the Config.in files
are still the same, but the prefix added to them is now CONFIG_LP_ instead of just
CONFIG_.

The template had a dependency on config.h which was correct for coreboot,
where this build system originally came from, but not for libpayload which
uses the differently named libpayload-config.h, presumably to avoid colliding
with a config.h used by the actual payload. Because libpayload-config.h is now
effectively a dependency of everything, it doesn't have to be added piecemeal
in Makefile.inc.

PDCurses provides an alternative implementation of the curses library
standard in addition to tinycurses.
Where tinycurses is really tiny, PDCurses is more complete and provides
virtually unlimited windows and the full API.
The PDCurses code is brought in "vanilla", with all local changes
residing in curses/pdcurses-backend/
In addition to a curses library, this change also provides libpanel (as
part of the PDCurses code), and libform and libmenu which were derived
from ncurses-5.9.
As they rely on ncurses internals (and PDCurses is not ncurses), more
changes were required for these libraries to work.
The build system is extended to install the right set of header files
depending on the selected curses implementation.
