dc45951e88 drivers/elog/elog: Add timestamps to elog_init
elog init requires doing a lot of SPI transactions. This change makes it
clear how long we spend initializing elog.

BUG=b:179699789
TEST=Boot guybrush and see elog init timestamps
 114:started elog init                                3,029,116 (88)
 115:finished elog init                               3,071,281 (42,165)

b28a035ea0 elog: move MAX_EVENT_SIZE to commonlib/bsd/include
Moves MAX_EVENT_SIZE to commonlib/bsd/include, and renames it
ELOG_MAX_EVENT_SIZE to give it an "scoped" name.

The moving is needed because this defined will be used from
util/cbfstool (see next CL in the chain).

e929a75fbe elog: move functionality to commonlib/bsd
This commit moves some drivers/elog/ functionality to commonlib/bsd
since they will be called from util/cbfstool/.

In particular:
 * elog_fill_timestamp(), elog_update_checksum(), elog_checksum_event()
   were moved to commonlib/bsd/elog
 * elog_fill_timestamp() receives the time parameters and updates the
   event based on the "time" arguments.

The original elog_*() functions were written by Duncan Laurie
(see CB:1311) and he gave permission to re-license the code to BSD.

954df3d6bf include/bcd: move bcd code to commonlib/bsd/include
Move bcd2bin() / bin2bcd() functions to commonlib/bsd/include/

Also, the license is changed from GPL to BSD.
This is because it is needed from "utils" (see CL in the chain).

For reference bin2bcd() & bcd2bin() are very simple functions.
There are already BSD implementations, like these ones (just to
name a few):

d45e70c124 Move elog_internal.h to commonlib/bsd/include
Move elog_internal.h to commonlib/bsd/include/bsd/.
And rename it from elog_internal.h to elog.h.

Since this file will be included from util/ it also converts the "uNN"
types into "uintNN_t" types.

The two defines that are not used by util/ are moved to
drivers/elog/elog.c, the only file that includes them.

Move also the function elog_verify_header() from drivers/elog/, to
commonlib/bsd/elog.c since this function will be called from util/
as well.

The rationale behind moving elog's defines & structs to
commonlib/bsd/include is to make them available to util/ tools and/or
payloads (should it be needed in the future).

The files that are being relicensed to BSD were coded by Duncan Laurie,
and he is Ok with the relicense.

c893197352 commonlib/region: Turn addrspace_32bit into a more official API
We had the addrspace_32bit rdev in prog_loaders.c for a while to help
represent memory ranges as an rdev, and we've found it useful for a
couple of things that have nothing to do with program loading. This
patch moves the concept straight into commonlib/region.c so it is no
longer anchored in such a weird place, and easier to use in unit tests.
Also expand the concept to the whole address space (there's no real need
to restrict it to 32 bits in 64-bit environments) and introduce an
rdev_chain_mem() helper function to make it a bit easier to use. Replace
some direct uses of struct mem_region_device with this new API where it
seems to make sense.

76cedd2c29 acpi: Move ACPI table support out of arch/x86 (3/5)
This change moves all ACPI table support in coreboot currently living
under arch/x86 into common code to make it architecture
independent. ACPI table generation is not really tied to any
architecture and hence it makes sense to move this to its own
directory.

In order to make it easier to review, this change is being split into
multiple CLs. This is change 3/5 which basically is generated by
running the following command:
$ git grep -iIl "arch/acpi" | xargs sed -i 's/arch\/acpi/acpi\/acpi/g'

540a98001d printf: Automatically prefix %p with 0x
According to the POSIX standard, %p is supposed to print a pointer "as
if by %#x", meaning the "0x" prefix should automatically be prepended.
All other implementations out there (glibc, Linux, even libpayload) do
this, so we should make coreboot match. This patch changes vtxprintf()
accordingly and removes any explicit instances of "0x%p" from existing
format strings.

How to handle zero padding is less clear: the official POSIX definition
above technically says there should be no automatic zero padding, but in
practice most other implementations seem to do it and I assume most
programmers would prefer it. The way chosen here is to always zero-pad
to 32 bits, even on a 64-bit system. The rationale for this is that even
on 64-bit systems, coreboot always avoids using any memory above 4GB for
itself, so in practice all pointers should fit in that range and padding
everything to 64 bits would just hurt readability. Padding it this way
also helps pointers that do exceed 4GB (e.g. prints from MMU config on
some arm64 systems) stand out better from the others.

c9b13594eb src/: Remove g_ prefixes and _g suffixes from variables
These were often used to distinguish CAR_GLOBAL variables that weren't
directly usable. Since we're getting rid of this special case, also get
rid of the marker.

This change was created using coccinelle and the following script:
	@match@
	type T;
	identifier old =~ "^(g_.*|.*_g)$";
	@@
	old

	@script:python global_marker@
	old << match.old;
	new;
	@@
	new = old
	if old[0:2] == "g_":
	  new = new[2:]

	if new[-2:] == "_g":
	  new = new[:-2]

	coccinelle.new = new

	@@
	identifier match.old, global_marker.new;
	@@
	- old
	+ new

	@@
	type T;
	identifier match.old, global_marker.new;
	@@
	- T old;
	+ T new;

	@@
	type T;
	identifier match.old, global_marker.new;
	@@
	- T old
	+ T new
	 = ...;

There were some manual fixups: Some code still uses the global/local
variable naming scheme, so keep g_* there, and some variable names
weren't completely rewritten.

a46ee4d34d elog: Ensure eventlog will always get initialized when configured in
Commit 0d9cd92e (chromeos: Clean up elog handling) removed the
individual elog_init() calls from mainboards that did them and automated
adding certain events through the boot state machine. Unfortunately,
the new code would sometimes not log any specific event at all, and
thereby also never call elog_init() (through elog_add_event()) which
adds the "System boot" event.

We can assume that any board that configures the eventlog at all
actually wants to use it, so let's just add another call to elog_init()
to the boot state machine so we can ensure it gets called at least once.

There were multiple paths where writes and erases of the flash

synchronization point resides as the very last thing done when
adding an event to the log. The shrinking check happens before
committing the event to non-volatile storage so there's no need
to attempt a shrink in elog_init() because any previous events
committed already honored the full threshold.
