The CPU on/off functions are the method for the Kernel to support CPU
hot-plug function in PSCI. To support this, we still need flow controller
support to capture the WFI from the CPU and inform PMC to power gate the
CPU core. On the other path, we turn on the CPU by toggling the PMC and
use flow controller to let go when the power is steady.
BUG=chrome-os-partner:32136
BRANCH=None
TEST=built the kernel with PSCI enabled,
check both of the CPUs are coming up,
test the CPU hot-plug is working on Ryu

In order to start CPUs while in secmon/psci one needs to
set up the proper SoC state. Therefore, refactor the current
CPU startup API to allow for this by adding cpu_prepare_startup()

Looks like Intel has added two more USB 2.0 ports from LynxPoint to
Broadwell, which shifted the port offsets of the USB 3.0 ports behind
them. The USB 2.0 ports are now 0x480 to 0x520 and the 3.0 ones 0x530 to
0x560 (at least according to what my kernel seems to think). The offset
of the first USB 3.0 port is hardcoded and seems to have been copied
over without accounting for this, meaning when we try to operate on all
USB 3.0 ports we actually operate on the last two 2.0 and the first two
3.0 ports instead.
This patch should fix the bug for now. In the future, we might want to
consider dynamically detecting port locations through the Protocol
Capability structures at the end of the XHCI register set instead.

To ensure that boot flags (legacy, usb, signed-only) are
properly restored from CMOS and used in the first boot after
a battery removal or RTC reset then the VbNv region needs to
be preserved around the cmos_init call.
When using vboot firmware selection and VbNv is stored in CMOS
then that region of CMOS will have been re-initialized by the
time we call cmos_init and reset CMOS if the chipset flag was
set indicating a problem.

This function will use the next available/free protected range
register to cover the specified region of flash and write
protect it until the next reset.
This will be used by the common MRC cache code to protect the
RW_MRC_CACHE region after it is updated.
In order to communicate to the common NVM code that this function
is defined also enable CONFIG_MRC_SETTINGS_PROTECT variable.

In order for some panels to meet spec when the system is put
into S5 by way of power button during firmware (i.e. not by
the OS) then it needs to turn off the backlight and give it
time to turn off before going into S5.
If the OS properly sequences the panel down then the backlight
enable bit will not be set in this step and nothing will happen.

save it in NVS so it can be returned in \_GPE._SWS method.

Provide support for SoCs to participate in PSCI commands.
There are 2 steps to a command:
1. prepare() - look at request and adjust state accordingly
2. commit() - take action on the command
The prepare() function is called with psci locks held while
the commit() function is called with the locks dropped.
No SoC implements the appropriate logic yet.

Newly turned on CPUs need a place to go bring its EL3
state inline with expectations. Plumb this path in for
CPUs turning on as well as waking up from a power down

moved around for easier consumption in ramstage and

Our CBFS header offset on rk3288 was very low and overlapped with the
end of the bootblock on recent Pinky builds. This can create all kinds
of fun effects like BSS variables suddenly being initialized to
something else than zero, in an effect that jumps somewhere else for
every slightest code size change.
This patch moves the CBFS header offset up a bit and the CBFS ROM offset
down (because there's really no point in leaving such a large gap). This
resolves our immediate booting problems, and I'll also start on a patch
to add further checks somewhere that catch these overlaps in the future.

Confirmed that I saw the same "Not enough room for another

This patch runs basic NAND initialization code on Proto 0.2 boards which
have been reworked for NAND. It makes sense to do this in coreboot for
two reasons:
- In general, it is reasonable for coreboot to initialize clocks and such
in preparation for depthcharge's use. Waiting times can be pooled, and
the initialization itself here is very fast.
- There is a kernel bug which requires that the clock is already initialized
before the kernel loads NAND support. coreboot is a more sensible place
to put a workaround than depthcharge because depthcharge initializes
things lazily, but when booting from USB, depthcharge won't need to look
at NAND.
This change involves bringing in an additional header file, ebi2.h, from U-Boot.
TEST=Booted a kernel from USB and verified that NAND came up without any
depthcharge hacks, whereas previously a USB-booted kernel would be unable
to access NAND even with the same drivers compiled in due to an initialization
failure.

We've had gpiolib.h which defines a few common GPIO access functions for
a while, but it wasn't really complete. This patch adds the missing
gpio_output() function, and also renames the unwieldy
gpio_get_in_value() and gpio_set_out_value() to the much easier to
handle gpio_get() and gpio_set(). The header is renamed to the simpler
gpio.h while we're at it (there was never really anything "lib" about
it, and it was presumably just chosen due to the IPQ806x include/
conflict problem that is now resolved).
It also moves the definition of gpio_t into SoC-specific code, so that
different implementations are free to encode their platform-specific
GPIO parameters in those 4 bytes in the most convenient way (such as the
rk3288 with a bitfield struct). Every SoC intending to use this common
API should supply a <soc/gpio.h> that typedefs gpio_t to a type at most
4 bytes in length. Files accessing the API only need to include <gpio.h>
which may pull in additional things (like a gpio_t creation macro) from
<soc/gpio.h> on its own.
For now the API is still only used on non-x86 SoCs. Whether it makes
sense to expand it to x86 as well should be separately evaluated at a
later point (by someone who understands those systems better). Also,
Exynos retains its old, incompatible GPIO API even though it would be a
prime candidate, because it's currently just not worth the effort.

In order to properly support more arm64 SoCs PSCI needs
to handle the hierarchy of cpus/clusters within the SoC.
The nodes within PSCI are kept in a tree as well as
a depth-first ordered array of same tree. Additionally,
the PSCI states are now maintained in a hierachal manner.
OFF propogates up the tree as long as all siblings are
set to OFF. ON propogates up the tree until a node is
not already set to OFF.
The SoC provides the operations for determining how many
children are at a given affinity level. Lastly, the
secmon startup has been reworked in that all non-BSP CPUs
wait for instructions from the BSP.

With the code now running on the FPGA board it makes sense to correct
the memory layout definitions to match the actual hardware.
Note that the latest FPGA board firmware introduced support of the
additional 128KB of SRAM (called GRAM) at base address of 0x9a000000.
These are still interim values, which will be tweaked when the actual
bring up board is available.

C0_COUNT register is a free running counter clocked by the CPU
frequency divided by two. On the FPGA board it results in 25 MHz, on
real SOCs it will have to be figured out later.
Some magic addresses and numbers are used to find out if the code is
running on the FPGA board.
timestamp_get() and timer_monotonic_get() are kept in the same file.
The CPU initialization makes sure that CO COUNT is in fact enabled and
starts from zero.

This patch is the start of a series to change all non-x86 SoC-specific
headers to be included as <soc/header.h> instead of the old
<soc/vendor/chip/header.h> or "header.h". It will add an include/soc/
directory under every src/soc/vendor/chip/ and append the .../include/
part of that to the global include path.
This matches the usage of <arch/header.h> for architecture-specific
headers and had already been done for some headers on Tegra. It has the
advantage that a source file which does not know the specific SoC used
(e.g. Tegra files common for multiple chips, or a global include file)
can still include SoC-specific headers and access macros/types defined
there. It also makes the includes for mainboard files more readable, and
reduces the chance to pull in a wrong header when copying mainboard
sources to use a different-related SoC (e.g. using a Tegra124 mainboard
as template for a Tegra132 one).
For easier maintainability, every SoC family is modified individually.
This patch starts out by changing Rk3288. Also alphabetized headers in
affected files since we touch them anyway.

Solving the DACR bug will mean that XN bits suddenly become enforced on
non-LPAE systems, and we will no longer be able to execute out of a
region mapped DCACHE_OFF. When we enable the MMU in romstage we are
still executing out of SRAM, so we would instantly kill ourselves.
Solve this issue by enabling the MMU earlier (in the bootblock) and
mapping the SRAM regions as DCACHE_WRITETHROUGH. They should really be
DCACHE_WRITEBACK, but it looks like there might be hardware limitations
in the Cortex-A12 cache architecture that prevent us from doing so.
Write-through mappings are equivalent to normal non-cacheable on the A12
anyway, and by using this attribute we don't need to introduce a new
DCACHE_OFF_BUT_WITHOUT_XN_BIT type in our API. (Also, using normal
non-cacheable might still have a slight speed advantage over strongly
ordered since it should fetch whole cache lines at once if the processor
finds enough accesses it can combine.)

This patch does some general cleanup in the Rockchip clock code, and
adds some more assertions regarding the PLL VCO and output frequency
ranges. It changes all PLL divisors to use the lowest values that can
still hit the target frequency, since higher NR values lead to higher
jitter and higher NO values increase power draw.
Also change DDR3 frequency code to hardcode the optimal divisors for
certail frequencies. As a little hack we will interpret 666000000 to
actually mean 666666666.6P (and analogous for 533MHz), since that's what
you usually want for memory.

This change re-writes the spi_xfer() function to support full-duplex
transfers.
Even though the code looks much different, the same basic algorithm
for setting up the transfer is used. The main difference is that
reads from rxdr and writes to txdr occur simultaneously and accounting
is more complicated, so I separated the higher-level accounting
portion from the low-level FIFO handling portion to simplify things.

This patch creates a new mechanism to define the static memory layout
(primarily in SRAM) for a given board, superseding the brittle mass of
Kconfigs that we were using before. The core part is a memlayout.ld file
in the mainboard directory (although boards are expected to just include
the SoC default in most cases), which is the primary linker script for
all stages (though not rmodules for now). It uses preprocessor macros
from <memlayout.h> to form a different valid linker script for all
stages while looking like a declarative, boilerplate-free map of memory
addresses to the programmer. Linker asserts will automatically guarantee
that the defined regions cannot overlap. Stages are defined with a
maximum size that will be enforced by the linker. The file serves to
both define and document the memory layout, so that the documentation
cannot go missing or out of date.
The mechanism is implemented for all boards in the ARM, ARM64 and MIPS
architectures, and should be extended onto all systems using SRAM in the
future. The CAR/XIP environment on x86 has very different requirements
and the layout is generally not as static, so it will stay like it is
and be unaffected by this patch (save for aligning some symbol names for
consistency and sharing the new common ramstage linker script include).
BUG=None
TEST=Booted normally and in recovery mode, checked suspend/resume and
the CBMEM console on Falco, Blaze (both normal and vboot2), Pinky and
Pit. Compiled Ryu, Storm and Urara, manually compared the disassemblies
with ToT and looked for red flags.

This patch adds the macros __ROMSTAGE__ and __RAMSTAGE__ which get
predefined in their respective stages by make, so that we have one
specific macro for every stage. It also renames __BOOT_BLOCK__ and
__VER_STAGE__ to __BOOTBLOCK__ and __VERSTAGE__ for consistency.
This change is intended to provide finer control and clearer
communication of intent after we added a new (optional) stage that falls
under __PRE_RAM__, and will hopefully provide some robustness for the
future (we don't want to end up always checking for romstage with #if
defined(__PRE_RAM__) && !defined(__BOOT_BLOCK__) &&
!defined(__VER_STAGE__) && !defined(__YET_ANOTHER_PRERAM_STAGE__)). The
__PRE_RAM__ macro stays as it is since many features do in fact need to
differentiate on whether RAM is available. (Some also depend on whether
RAM is available at the end of a stage, in which case #if
!defined(__PRE_RAM__) || defined(__ROMSTAGE__) should now be
authoritative.)
It's unfeasable to change all existing occurences of __PRE_RAM__ that
would be better described with __ROMSTAGE__, so this patch only
demonstratively changes a few obvious ones in core code.
BUG=None
TEST=None (tested together with dependent patch).
