Many ChromeOS devices use a GPIO to reset the system, in order to
guarantee that the TPM cannot be reset without also resetting the CPU.
Often chipset/SoC hardware watchdogs trigger some kind of built-in
CPU reset, bypassing this GPIO and thus leaving the TPM locked. These
ChromeOS devices need to detect that condition in their bootblock and
trigger a second (proper) reboot.
This patch adds some code to generalize this previously
mainboard-specific functionality and uses it on Veyron boards. It also
provides some code to add the proper eventlog entry for a watchdog
reset. Since the second reboot has to happen before firmware
verification and the eventlog is usually only initialized afterwards, we
provide the functionality to place a tombstone in a memlayout-defined
location (which could be SRAM or some MMIO register that is preserved
across reboots).

We've traditionally tucked the framebuffer at the end of memory (above
CBMEM) on ARM and declared it reserved through coreboot's resource
allocator. This causes depthcharge to mark this area as reserved in the
kernel's device tree, which may be necessary to avoid display corruption
on handoff but also wastes space that the OS could use instead.
Since rk3288 boards now have proper display shutdown code in
depthcharge, keeping the framebuffer memory reserved across the handoff
(and thus throughout the lifetime of the system) should no longer be
necessary. For now let's just switch the rk3288 implementation to define
it through memlayout instead, which is not communicated through the
coreboot tables and will get treated as normal memory by depthcharge.
Note that this causes it to get wiped in developer/recovery mode, which
should not be a problem because that is done in response to VbInit()
(long before any images are drawn) and 0 is the default value for a
corebootfb anyway (a black pixel).
Eventually, we might want to think about adding more memory types to
coreboot's resource system (e.g. "reserved until kernel handoff", or
something specifically for the frame buffer) to model this situation
better, and maybe merge it with memlayout somehow.

We want a reset signal to last 200us. The length of a reset signal is
represented by BIT0~BIT16 in DDR_PUBL_PTR2. When DDR memory runs at
667MHz, the calculated value for the reset signal is 0x20850, which is
bigger than the maximum value that can be described with 17 bits
(0x1ffff). As a result, the memory controller only sees 0x850, which
generates a 3.5us reset cycle instead, which violates the standard and
negatively impacts memory stability.
So instead, we now set it to the maximum value (0x1ffff) to prevent this
overflow, resulting in a reset signal of 196us for 667MHz DDR memory.

With introduction of uber-sbl SRAM usage pattern is changing, this
introduces the new memory layout.
This patch overlays DDR initialization code with uber-sbl, as uber-sbl
goes out of scope as soon as bootblock starts.
A 4K block at offset 0x3f000 added in the comments, this is a shared
structure used by different QCA modules.
This suggested layout is not final, but will allow to move closer to
the production image.

This moves PMIC_BUS from each mainboard's board.h file to a per-
mainboard Kconfig variable. To prevent humans from forgetting to
set a valid value, an invalid default is set in the rk3288 Kconfig
and checked in rk808.c so that compilation will fail if the mainboard
Kconfig does not override it.
Originally, PMIC_BUS was only used by mainboard code as an argument
to RK808 PMIC functions. To conform to the generic RTC API, however,
the RK808 code needs to have the bus number globally defined somewhere
since the rtc_get() and rtc_set() functions don't take any args.
Since CONFIG_PMIC_BUS is globally visible, we no longer need to pass
bus number to the PMIC functions.

This switches all the rk3288 platforms to use the common CBFS wrapper
instead of implementing its own CBFS media driver. It also happens
that veyron_* platforms use Gigadevice SPI flash (at least for now).
As we use more SPI-related stuff, for example eventlog and vboot data in
Brain's case, we will need to use more of the SPI API anyway. This
prevents us from having to duplicate pieces of it for rk3288.

Like Nyan, Veyron boards use a GPIO to reset the system so that we can
make the accompanying TPM reset secure and unforgeable. The normal
kernel reboot driver knows that, but the SoC-internal watchdog doesn't.
This patch implements a check for the global reset status register in
the early bootblock and triggers a hard_reset() when it matches "first
global watchdog reset" or "second global watchdog reset". Seems that
the difference between the two is is a choice controlled by
wdt_glb_srst_ctrl (unconfirmed), and we want this code to run in both
cases.

The only way to reliably reset an SD card in an unknown state is by
power-cycling. Since a kernel may crash and reboot at any point, SD
cards may be left in one of them fancy high-throughput modes that
depthcharge (or, in fact, a newly booting kernel without prior
knowledge) doesn't support, so we need to reset the card on every boot.
This patch adds support to turn off an RK808 regulator completely and
uses that to turn off SD card power rails in early romstage. The time
until configure_sdmmc() in ramstage turns them back on should be more
than enough to drain the power rail for an effective power-cycle.

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.

This allows us to get rid of the hacky second console_init() call in

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.
Further cleanup is necessary and on the short-term TODO, but beyond
the scope of this commit]

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.

Some SPI controllers (like Imgtec Pistachio), have a hard limit on SPI
read and write transactions. Limiting transfer size in the wrapper
allows to provide the API user with unlimited transfer size
transactions.
The tranfer size limitation is added to the spi_slave structure, which
is set up by the controller driver. The value of zero in this field
means 'unlimited transfer size'. It will work with existion drivers,
as they all either keep structures in the bss segment, or initialize
them to all zeros.
This patch addresses the problem for reads only, as coreboot is not
expected to require to write long chunks into SPI devices.

LDO7 (VCC10_LCD_PWREN_H) is essentially just a glorified GPIO that turns
the real VCC10 regulator on or off. We tried setting it to 3.3V since it
matches the VCC33_SYS voltage on the input of that regulator. However,
we didn't notice that the LDO only supports going up to 2.5V.
This patch changes the voltage to the allowed maximum, which should
still work fine as an enable line (and is the same value used by the
kernel). This removes an assertion error in the ramstage.
Also change the PMIC driver to assert maximum VSEL values based on the
LDO, because the lower-voltage ones support one more setting. (LDO3 is
actually listed to only go up to 0b1111 in the manual, and has a weird
jump from 0b1101 -> 2.2V (skipping over 0b1110) to 0b1111 -> 2.5V. I
don't know if that's a documentation error or what they were smoking
when they designed that, but we don't need to care for now.)
