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).

startup.c provides function to enable CPU in any stage to save register data
that can be used by secondary CPU (for normal boot) or any CPU (for resume
boot). stage_entry.S defines space for saving arm64_startup_data. This can be
filled by:
1) Primary CPU before bringing up secondary CPUs so that the secondary can use
register values to initialize MMU-related and other required registers to
appropriate values.
2) CPU suspend path to ensure that on resume the values which were saved are
restored appropriately.
stage_entry.S provides a common path for both normal and resume boot to
initialize saved registers. For resume path, it is important to set the
secondary entry point for startup since x26 needs to be 1 for enabling MMU and
cache.
This also ensures that we do not fall into false memory cache errors which
caused CPU to fail during normal / resume boot. Thus, we can get rid of the
stack cache invalidate for secondary CPUs.

Secondary CPUs were intermittently not coming online as expected.
Upon investigation it was found that a cache line needed to be
invalidated that corresponded to the top of the stack for the
failing CPU.
Currently the secondary CPUs come online with caching disabled.
However, the code paths are using C and thus the stack it is assigned.
The MMU is enabled in C after it's pushed its return path onto the
stack that went directly to ram. When the cache line corresponding
to its stack is valid in the cache it will hit once the MMU is enabled.
That hit will have invalid data w.r.t. the return addresses pushed
directly into ram.
This is not the best solution as the only way to guarantee we don't
hit such a situation is to tightly manage resource usage up until
the point of MMU enablement. That can be done in a followup patch.

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.
BUG=chrome-os-partner:32136
BRANCH=None
TEST=Booted PSCI kernel -- no SMP because cmd_prepare()
knowingly fails. Spintable kernel still brings up both
CPUs.

state inline with expectations. Plumb this path in for
CPUs turning on as well as waking up from a power down

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.

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).

Secmon needs a special build rule because of the objcopy -B

manual template so builds continue to work with upcoming

Note: secmon is actually missing symbols still so those

the symbols are just erroneously carried over as the

calls: 1. platform_prog_run() and 2. arch_prog_run().
The platform_prog_run() allows for a chipset to intercept
a program that will be run. This allows for CPU switching
as currently needed in t124 and t132.

The struct prog serves as way to consolidate program
loading. This abstraction can be used to perform more
complicated execution paths such as running a program
on a separate CPU after it has been loaded. Currently
t124 and t132 need to do that in the boot path. Follow
on patches will allow the platform to decide how to
execute a particular program.
Note: the vboot path is largely untouched because it's
already broken in the coreboot.org tree. After getting
all the necessary patches pushed then vboot will be
fixed.

It's an unfortunate side effect of our different-archs-per-stage
mechanism that all src/arch/*/Kconfig files are always parsed with no
if blocks to exclude them if they're not relevant. This makes it very
easy to accidentally rely on a Kconfig default set by a totally
different and not applying architecture.
This patch moves a few Kconfigs from ARM and X86 that leaked out like
this into a common Kconfig file for clarity. It also gives ARM64 its
own BOOTBLOCK_CUSTOM mechanism so that it doesn't leech off the ARM one
(currently not used by any board).
In the future, we should maybe prefix all options in the arch/*/Kconfig
files with the architecture name (such as X86_BOOTBLOCK_NORMAL and
ARM_LPAE are already doing), to make it more apparent when they are used
in the wrong place.

Transition library provides the following functionalities:
1) Setup the environment for switching to any particular EL and jump to the
loaded program at that EL. In short "Execute program X at exception level Y
using the state Z"
2) Provides routines for exception entry and exception exit that can be used by
any program to implement exception handling. The only routine required by the
program would be exc_dispatch which handles the exception in its own required
way and returns by making a call to exc_exit. On exc_exit, the transition
library unwinds the whole stack by popping out the saved state of xregs

Depending on the armv8 implementation the cpus could start in
EL1, EL2, or EL3. Therefore allow the SoC to select the appropriate
mode.

There are 2 things wrong with the current implementation:
1. the stack isn't guaranteed to be aligned to CONFIG_STACK_SIZE.
2. the stack isn't necessarily CONFIG_STACK_SIZE bytes.
Utilize the smp_processor_id() function to obtain the correct
cpu_info structure to obtain the correct index.

In order to accomodate MP on arm64 one needs to be able to determine

implementation the SoC needs to provide this implementation.

The GCC 4.9.2 update showed that the boot_state_init_entry
structures were being padded and assumed to be aligned in to an
increased size. The bootstate scheduler for static entries,
boot_state_schedule_static_entries(), was then calculating the
wrong values within the array. To fix this just use a pointer to
the boot_state_init_entry structure that needs to be scheduled.
In addition to the previous issue noted above, the .bs_init
section was sitting in the read only portion of the image while
the fields within it need to be writable. Also, the
boot_state_schedule_static_entries() was using symbol comparison
to terminate a loop which in C can lead the compiler to always
evaluate the loop at least once since the language spec indicates
no 2 symbols can be the same value.

Currently, the rmodules inclusion for vboot is dependent on ramstage_arch.
This change adds dependency on romstage_arch, since vboot is associated with
romstage. Inclusion based on ramstage_arch is left as is in case someone needs
it in ramstage.
