checkstack() runs at the end of ramstage to warn about stack overflows,
and it assumes that CONFIG_STACK_SIZE is always the size of the stack to
check. This is only true for systems that bring up multiprocessing in
ramstage and assign a separate stack for each core, like x86 and ARM64.
Other architectures like ARM and MIPS (for now) don't touch secondary
CPUs at all and currently don't look like they'll ever need to, so they
generally stay on the same (SRAM-based) stack they have been on since
their bootblock.
This patch tries to model that difference by making these architectures
explicitly set CONFIG_STACK_SIZE to zero, and using that as a cue to
assume the whole (_estack - _stack) area in checkstack() instead. Also
adds a BUG() to the stack overflow check, since that is currently just
as non-fatal as the BIOS_ERR message (despite the incorrect "SYSTEM
HALTED" output) but a little more easy to spot. Such a serious failure
should not drown out in all the normal random pieces of lower case boot
spam (also, I was intending to eventually have a look at assert() and
BUG() to hopefully make them a little more useful/noticeable if I ever

of them. This patch adds several timestamps to both the bootblock and
especially the verstage to allow more fine-grained boot time tracking.
Some of the introduced timestamps can appear more than once per boot.
This doesn't seem to be a problem for both coreboot and the cbmem
utility, and the context makes it clear which operation was timestamped
at what point.
Also simplifies cbmem's timestamp printing routine a bit, fixing a

Since we can now reduce our vboot2 work buffer by 4K, we can use all
that hard-earned space for the CBMEM console instead (and 4K are
unfortunately barely enough for all the stuff we dump with vboot2).
Also add console_init() and exception_init() to the verstage for
CONFIG_RETURN_FROM_VERSTAGE, which was overlooked before (our model
requires those functions to be called again at the beginning of every
stage... even though some consoles like UARTs might not need it, others
like the CBMEM console do). In the !RETURN_FROM_VERSTAGE case, this is
expected to be done by the platform-specific verstage entry wrapper, and
already in place for the only implementation we have for now (tegra124).
(Technically, there is still a bug in the case where EARLY_CONSOLE is
set but BOOTBLOCK_CONSOLE isn't, since both verstage and romstage would
run init_console_ptr() as if they were there first, so the romstage
overwrites the verstage's output. I don't think it's worth fixing that
now, since EARLY_CONSOLE && !BOOTBLOCK_CONSOLE is a pretty pointless
use-case and I think we should probably just get rid of the
CONFIG_BOOTBLOCK_CONSOLE option eventually.)

We have known for a while that the old x86 model of calling init_timer()
in ramstage doesn't make sense on other archs (and is questionable in
general), and finally removed it with CL:219719. However, now timer
initialization is completely buried in the platform code, and it's hard
to ensure it is done in time to set up timestamps. For three out of four
non-x86 SoC vendors we have brought up for now, the timers need some
kind of SoC-specific initialization.
This patch reintroduces init_timer() as a weak function that can be
overridden by platform code. The call in ramstage is restricted to x86
(and should probably eventually be removed from there as well), and
other archs should call them at the earliest reasonable point in their
bootblock. (Only changing arm for now since arm64 and mips bootblocks
are still in very early state and should sync up to features in arm once
their requirements are better understood.) This allows us to move
timestamp_init() into arch code, so that we can rely on timestamps
being available at a well-defined point and initialize our base value as
early as possible. (Platforms who know that their timers start at zero
can still safely call timestamp_init(0) again from platform code.)

Non-x86 boards currently need to hardcode the position of their CBFS
master header in a Kconfig. This is very brittle because it is usually
put in between the bootblock and the first CBFS entry, without any
checks to guarantee that it won't overlap either of those. It is not fun
to debug random failures that move and disappear with tiny alignment
changes because someone decided to write "ORBC1112" over some part of
your data section (in a way that is not visible in the symbolized .elf
binaries, only in the final image). This patch seeks to prevent those
issues and reduce the need for manual configuration by making the image
layout a completely automated part of cbfstool.
Since automated placement of the CBFS header means we can no longer
hardcode its position into coreboot, this patch takes the existing x86
solution of placing a pointer to the header at the very end of the
CBFS-managed section of the ROM and generalizes it to all architectures.
This is now even possible with the read-only/read-write split in
ChromeOS, since coreboot knows how large that section is from the
CBFS_SIZE Kconfig (which is by default equal to ROM_SIZE, but can be
changed on systems that place other data next to coreboot/CBFS in ROM).
Also adds a feature to cbfstool that makes the -B (bootblock file name)
argument on image creation optional, since we have recently found valid
use cases for CBFS images that are not the first boot medium of the
device (instead opened by an earlier bootloader that can already
interpret CBFS) and therefore don't really need a bootblock.

Some projects (like ChromeOS) put more content than described by CBFS
onto their image. For top-aligned images (read: x86), this has
traditionally been achieved with a CBFS_SIZE Kconfig (which denotes the
area actually managed by CBFS, as opposed to ROM_SIZE) that is used to
calculate the CBFS entry start offset. On bottom-aligned boards, many
define a fake (smaller) ROM_SIZE for only the CBFS part, which is not
consistently done and can be an issue because ROM_SIZE is expected to be
a power of two.
This patch changes all non-x86 boards to describe their actual
(physical) ROM size via one of the BOARD_ROMSIZE_KB_xxx options as a
mainboard Kconfig select (which is the correct place to declare
unchangeable physical properties of the board). It also changes the
cbfstool create invocation to use CBFS_SIZE as the -s parameter for
those architectures, which defaults to ROM_SIZE but gets overridden for
special use cases like ChromeOS. This has the advantage that cbfstool
has a consistent idea of where the area it is responsible for ends,
which offers better bounds-checking and is needed for a subsequent fix.
Also change the FMAP offset to default to right behind the (now
consistently known) CBFS region for non-x86 boards, which has emerged as
a de-facto standard on those architectures and allows us to reduce the
amount of custom configuration. In the future, the nightmare that is
ChromeOS's image build system could be redesigned to enforce this
automatically, and also confirm that it doesn't overwrite any space used
by CBFS (which is now consistently defined as the file size of
coreboot.rom on non-x86).

With the Storm image layout reworked, the very first blob read out of
NOR SPI flash by the IPQ8064 maskrom is supposed to be a concatenation
of three binaries: one to run on RPM, another one to run on AP, and
the third one - the actual coreboot bootblock.
This layout allows to greatly reduce the size and complexity of the
two first blobs, as they do not need to include the SPI driver.
The first binary in the input file list starts with the combined
header, describing the rest of the blob. This utility copies the first
input file into output, updating the combined header with the total
size of the concatenated binaries.
The second and third binaries in the combined image are required to be
aligned at 256 byte offsets in the file as counted from the end of
the combined header. The new utility allows to concatenate two or
three files, always expecting the first file to be prepended by the
combined header.
For further reference below is the utility's help message:

This patch uses the new bootblock_mainboard_early_init() hook to run the
UART pinmuxing on rk3288-based boards before initializing the console.
This allows us to get rid of the hacky second console_init() call in
bootblock_soc_init(). We can also simplify the pinmux selection a bit
since we know that a given board always uses the same UART (still keep
an assert around to be sure, though).

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.

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.
[pg: this was already partly upstreamed. These are the remains.

With this change, audio 'beeps' are heard on boot if Ctrl-U is
pressed, or devmode/recmode is entered. I also tested via an
explicit call to VbExBeep in the kernel boot path. Note that
a couple of Rush CLs for depthcharge are needed for audio, too.
BUG=chrome-os-partner:32582
BRANCH=none
TEST=as above. Built and booted Rush/Norrin64.

After DDR PHY reset de-asserted, DLL automatically starts to
lock, and the lock time is maximum 5.12us. The output clock of
DLL supplies the clocks of DDR controller and PHY digital logic.
So before DLL lock, the clocks of DDR controller and PHY digital
logic are indeterminate. When programming DDR in the period of
DLL unlock, the programming maybe unstable because of the
indeterminate clocks. So we need wait for at least 5.12us after
de-asserting reset, then start to program DDR registers.
10us provide some safety margin.

TEST=I'm using the following command line test ok(15000 cycles).
"while sleep 4 && dut-control cold_reset:on sleep:.1 cold_reset:off;
do : ; done"
