Paul Menzel db23215039 device/device.c: Improve output in `init_dev()`
Since commit 05294292 (device tree: track init times) there are two
lines printed for each init() call of a device, when
`HAVE_MONOTONIC_TIMER` is selected.

	[…]
	CPU_CLUSTER: 0 init 12708 usecs
	DOMAIN: 0000 init
	DOMAIN: 0000 init 1 usecs
	PCI: 00:00.0 init
	Northbridge init
	PCI: 00:00.0 init 2 usecs
	PCI: 00:01.0 init
	PCI: 00:01.0 init 1 usecs
	PCI: 00:01.1 init
	PCI: 00:01.1 init 1 usecs
	PCI: 00:11.0 init
	PCI: 00:11.0 init 1 usecs
	PCI: 00:14.0 init
	PCI: 00:14.0 init 1 usecs
	PCI: 00:14.3 init
	SB800 - Late.c - lpc_init - Start.
	RTC Init
	RTC: coreboot checksum invalid
	SB800 - Late.c - lpc_init - End.
	[…]

Improve the output by changing the wording to.

	%s init ...\n
	init()
	%s init finished in %ld usecs\n

Note, that `%s init ... done in %ld usecs` is not possible as the
function `init()` can also print messages.

Vladimir Serbinenko c16e9dfa18 Create i945-ivy smm tseg init based on ivy code.
CPU-side logic is unchanged for this range of CPUs as long as all of them
use TSEG (or ASEG, just needs to be consistent). So uplift 206ax code while
extracting southbridge and APIC code into separate functions.

Kyösti Mälkki 4fbac46524 cbmem: Unify CBMEM init tasks with CBMEM_INIT_HOOK() API
Squashed and adjusted two changes from chromium.git. Covers
CBMEM init for ROMTAGE and RAMSTAGE.

cbmem: Unify random on-CBMEM-init tasks under common CBMEM_INIT_HOOK() API

There are several use cases for performing a certain task when CBMEM is
first set up (usually to migrate some data into it that was previously
kept in BSS/SRAM/hammerspace), and unfortunately we handle each of them
differently: timestamp migration is called explicitly from
cbmem_initialize(), certain x86-chipset-specific tasks use the
CAR_MIGRATION() macro to register a hook, and the CBMEM console is
migrated through a direct call from romstage (on non-x86 and SandyBridge
boards).

This patch decouples the CAR_MIGRATION() hook mechanism from
cache-as-RAM and rechristens it to CBMEM_INIT_HOOK(), which is a clearer
description of what it really does. All of the above use cases are
ported to this new, consistent model, allowing us to have one less line
of boilerplate in non-CAR romstages.

BRANCH=None
BUG=None
TEST=Built and booted on Nyan_Blaze and Falco with and without
CONFIG_CBMEM_CONSOLE. Confirmed that 'cbmem -c' shows the full log after
boot (and the resume log after S3 resume on Falco). Compiled for Parrot,
Stout and Lumpy.

cbmem: Extend hooks to ramstage, fix timestamp synching

Commit 7dd5bbd71 (cbmem: Unify random on-CBMEM-init tasks under common
CBMEM_INIT_HOOK() API) inadvertently broke ramstage timestamps since
timestamp_sync() was no longer called there. Oops.

This patch fixes the issue by extending the CBMEM_INIT_HOOK() mechanism
to the cbmem_initialize() call in ramstage. The macro is split into
explicit ROMSTAGE_/RAMSTAGE_ versions to make the behavior as clear as
possible and prevent surprises (although just using a single macro and
relying on the Makefiles to link an object into all appropriate stages
would also work).

This allows us to get rid of the explicit cbmemc_reinit() in ramstage
(which I somehow accounted for in the last patch without realizing that
timestamps work exactly the same way...), and replace the older and less
flexible cbmem_arch_init() mechanism.

Also added a size assertion for the pre-RAM CBMEM console to memlayout
that could prevent a very unlikely buffer overflow I just noticed.

BRANCH=None
BUG=None
TEST=Booted on Pinky and Falco, confirmed that ramstage timestamps once
again show up. Compile-tested for Rambi and Samus.

The cbmem util needs the CBMEM_IDs and the strings for
reporting and shares the cbmem.h file with coreboot. Split out
the IDs so for a simpler sharing and no worries about overlap of
standard libraries and other things in the header that coreboot
requires, but the tool does not.

Mono 62805e60c0 macbook21: switch off led before jumping to payload
Mimic vendor BIOS in switching off the led once coreboot has booted
successfully. Currently the led behavior is inconsistent. The led turns on
during poweron and stays on forever. When entering S3 and during S3 it
blinks and turns off after wake from S3. The behavior associated with S3
is the same under vendor BIOS and under coreboot. Switching off the led
before jumping to the payload makes the led behavior consistent within
coreboot before S3 and after wake from S3 and it makes the led behavior
consistent to vendor BIOS.

Julius Werner 7a8a4ab1d8 lib: Unify log2() and related functions
This patch adds a few bit counting functions that are commonly needed
for certain register calculations. We previously had a log2()
implementation already, but it was awkwardly split between some C code
that's only available in ramstage and an optimized x86-specific
implementation in pre-RAM that prevented other archs from pulling it
into earlier stages.

Using __builtin_clz() as the baseline allows GCC to inline optimized
assembly for most archs (including CLZ on ARM/ARM64 and BSR on x86), and
to perform constant-folding if possible. What was previously named log2f
on pre-RAM x86 is now ffs, since that's the standard name for that
operation and I honestly don't have the slightest idea how it could've
ever ended up being called log2f (which in POSIX is 'binary(2) LOGarithm
with Float result, whereas the Find First Set operation has no direct
correlation to logarithms that I know of). Make ffs result 0-based
instead of the POSIX standard's 1-based since that is consistent with
clz, log2 and the former log2f, and generally closer to what you want
for most applications (a value that can directly be used as a shift to
reach the found bit). Call it __ffs() instead of ffs() to avoid problems
when importing code, since that's what Linux uses for the 0-based
operation.

CQ-DEPEND=CL:273023
BRANCH=None
BUG=None
TEST=Built on Big, Falco, Jerry, Oak and Urara. Compared old and new
log2() and __ffs() results on Falco for a bunch of test values.

If SB_HT_CHAIN_ON_BUS0 is selected, HyperTransport chain for System Bus
is the first to scan and it will be assigned with bus number 0.

If HT_CHAIN_DISTRIBUTE is selected, each link will reserve a fixed range
of bus numbers instead of assigning consecutive numbers across all the links.

All fam10 have SB_HT_CHAIN_ON_BUS0 selected under northbridge.
Follow-up can easily drop this if we find this is dictated by architecture.
