On non-x86 systems, the location of the preram CBMEM console may not be in a
predictable place relative to other things in the linker script. That makes it
difficult to work with as its own section because the linker will complain if
you try to move backwards as it lays out memory. If the console header is
treated as an actual blob of memory which has to be put in the image, we'd
have to predict where to put it so that it isn't before something with a lower
address or after something with a higher address. Symbols, on the other hand,
can be defined arbitrarily.

Virtual Wire mode is set by writing 0 to the the MPTable
Feature2 bit field 'IMCR'. The virtualwire variable was
initially defined as writing a 1 to this bit field which
would actually set PIC mode instead of Virtual Wire mode.
However, nearly every mainboard called the MPTables with
virtualwire = 0, which actually had the effect of setting
Virtual Wire mode. I am correcting the definition but
leaving the call to write the MPTables with virtualwire = 0,
which is how most mainboards are already setting the tables
up.
See the MP Spec table 4-1 for more details:
Bit 7: IMCRP. When the IMCR presence bit is
set, the IMCR is present and PIC Mode is
implemented; otherwise, Virtual Wire Mode is
implemented.

Improve clang compatibility by dropping an opaque hack
The section attribute was only ever meant for specifying
section names, not their properties - otherwise they would
have provided section(name,attribute,class) instead of only
section(name).
The hack to add attribute and class to the name, and commenting
out the "real" definitions inserted by the compiler (see the
terminating "#"), is refused by clang developers.
This is a cleaner implementation in that the section is first
declared with its properties, then used later-on, expecting that
later conflicting declarations are ignored.
It can still break in two ways:
1. The assembler or linker could complain about a section declared
in two different ways.
2. The assembler could just use the latest declaration, not the first,
to determine the section's properties.
I won't sort these out unless they actually happen.

walkcbfs() is used only with ROMCC. Besides finding stages during the
bootblock, it's also used when applying microcode updates during the
bootblock phase. The function used to return only a pointer to the data of
the CBFS file, while making the header completely inaccessible. Since the
header contains the length of the CBFS file, the caller did not have a way
to know how long the data was. Then, other conventions had to be used to
determine the EOF, which might present problems if the user replaces the
CBFS file. This is not an issue when jumping to a stage (romstage), but can
present problems when accessing a microcode file which has not been
NULL-terminated.
Refactor walkcbfs_asm to return a pointer to the CBFS file header rather
than the data. Rename walkcbfs() to walkcbfs_head(), and reimplement a new
walkcbfs() based on walkcbfs_head(). Thus current usage of walkcbfs()
remains unaffected.
The code has been verified to run successfully under qemu.
Subsequent patches will change usage of walkcbfs() to walkcbfs_head where
knowing the length of the data is needed.

still ran synchronously from within the main thread's context.
Without any other code added the only change to the boot sequence
when cooperative multitasking is enabled is the queueing of an idlle
thread. The idle thread is responsible for ensuring progress is made
by calling timer callbacks.
The main thread can yield to any other threads in the system. That
means that anyone that spins up a thread must ensure no shared
resources are used from 2 or more execution contexts. The support
is originally intentioned to allow for long work itesm with busy
loops to occur in parallel during a boot.
Note that the intention on when to yield a thread will be on

It's helpful to provide a distinct state that affirmatively
describes that OS resume will occur. The previous code included
the check and the actual resuming in one function. Because of this
grouping one had to annotate the innards of the ACPI resume
path to perform specific actions before OS resume. By providing
a distinct state in the boot state machine the necessary actions
can be scheduled accordingly without modifying the ACPI code.

Here's the great news: From now on you don't have to worry about
hitting the right io.h include anymore. Just forget about romcc_io.h
and use io.h instead. This cleanup has a number of advantages, like
you don't have to guard device/ includes for SMM and pre RAM
anymore. This allows to get rid of a number of ifdefs and will
generally make the code more readable and understandable.
Potentially in the future some of the code in the io.h __PRE_RAM__
path should move to device.h or other device/ includes instead,
but that's another incremental change.

This patch adds a parallel implementation of cbmem that supports
dynamic sizing. The original implementation relied on reserving
a fixed-size block of memory for adding cbmem entries. In order to
allow for more flexibility for adding cbmem allocations the dynamic
cbmem infrastructure was developed as an alternative to the fixed block
approach. Also, the amount of memory to reserve for cbmem allocations
does not need to be known prior to the first allocation.
The dynamic cbmem code implements the same API as the existing cbmem
code except for cbmem_init() and cbmem_reinit(). The add and find
routines behave the same way. The dynamic cbmem infrastructure
uses a top down allocator that starts allocating from a board/chipset
defined function cbmem_top(). A root pointer lives just below
cbmem_top(). In turn that pointer points to the root block which
contains the entries for all the large alloctations. The corresponding
block for each large allocation falls just below the previous entry.
It should be noted that this implementation rounds all allocations
up to a 4096 byte granularity. Though a packing allocator could
be written for small allocations it was deemed OK to just fragment
the memory as there shouldn't be that many small allocations. The
result is less code with a tradeoff of some wasted memory.
+----------------------+ <- cbmem_top()
| +----| root pointer |
| | +----------------------+
| | | |--------+
| +--->| root block |-----+ |

| | alloc N |<----+ |

v +----------------------+
In addition to preserving the previous cbmem API, the dynamic
cbmem API allows for removing blocks from cbmem. This allows for
the boot process to allocate memory that can be discarded after
it's been used for performing more complex boot tasks in romstage.
In order to plumb this support in there were some issues to work
around regarding writing of coreboot tables. There were a few
assumptions to how cbmem was layed out which dictated some ifdef
guarding and other runtime checks so as not to incorrectly
tag the e820 and coreboot memory tables.
The example shown below is using dynamic cbmem infrastructure.
The reserved memory for cbmem is less than 512KiB.

In order to restore this pointer it needs to be available
at resume time. The method used to locate it at creation
time cannot be used again as that magic signature is
overwritten with the address itself. So a new CBMEM ID
is added to store the 32bit address so it can be found
again easily.
A new function is defined to save this pointer in CBMEM

in each mainboard when write_acpi_tables() is called.

Adding ranges directly into coreboot memory table raised issues
as those methods bypassed the MTRR setup. Such regions are now
added as resources, so declare the functions again as static.

We thought about two ways to do this change. The way we decided to try
was to
1. drop all ops from devices in romstage
2. constify all devices in romstage (make them read-only) so we can
compile static.c into romstage
3. the device tree "devices" can be used to read configuration from
the device tree (and nothing else, really)
4. the device tree devices are accessed through struct device * in
romstage only. device_t stays the typedef to int in romstage
5. Use the same static.c file in ramstage and romstage
We declare structs as follows:
ROMSTAGE_CONST struct bus dev_root_links[];
ROMSTAGE_CONST is const in romstage and empty in ramstage; This
forces all of the device tree into the text area.
So a struct looks like this:
static ROMSTAGE_CONST struct device _dev21 = {
#ifndef __PRE_RAM__
.ops = 0,
#endif
.bus = &_dev7_links[0],
.path = {.type=DEVICE_PATH_PCI,{.pci={ .devfn = PCI_DEVFN(0x1c,3)}}},
.enabled = 0,
.on_mainboard = 1,
.subsystem_vendor = 0x1ae0,
.subsystem_device = 0xc000,
.link_list = NULL,
.sibling = &_dev22,
#ifndef __PRE_RAM__
.chip_ops = &southbridge_intel_bd82x6x_ops,
#endif
.chip_info = &southbridge_intel_bd82x6x_info_10,
.next=&_dev22
};

The existing NVS variable for PPCM will be used to
select a dynamic max P-state.
By itself this does not change existing behavior because
the NVS PPCM variable is initialized to zero.
PPCM can be tested by building and booting a modified BIOS
that sets gnvs->ppcm to a value greater than 1 and checking
from the OS that the P-state is limited to that value.

coreboot used to pass some information to u-boot in the coreboot table
and other information in a modified flat device tree. Since the FDT code
was never upstreamed and removed from our tree, u-boot was changed to
get the information it needs from the coreboot table alone. However,
in the process of this change only the vboot shared data structure was
passed on by coreboot, so when u-boot tried to update the ChromeOS
specific ACPI entries, it would accidently overwrite the vboot data.
This patch passes on the ChromeOS specific ACPI data structure instead
of the vboot shared data. Another change to u-boot will teach it how
to get to the vboot shared data from there.

PCI Type 2 config was a strange and never-used config mechanism.
It is unlikely that in the 13 years of coreboot's existence that
type 2 was ever used; it just made life complicated for everyone.
It lived long enough in coreboot to be replaced by mmioconf.
Prior to making the device tree visible in romstage we want to
get rid of type2.
Delete two files we don't need any more (yay!).
Replace two functions with one: pci_config_default, which returns
a pointer to the default config method. At some future time this
may change to mmio but for now it is old type1 style.

The current code for initializing AP cpus has several shortcomings:
- it assumes APIC IDs are sequential
- it uses only the BSP for determining the AP count, which is bad if
there's more than one physical CPU, and CPUs are of different type
Note that the new code call cpu->ops->init() in parallel, and therefore
some CPU code needs to be changed to address that. One example are old
Intel HT enabled CPUs which can't do microcode update in parallel.

When compiling coreboot with the latest ChromeOS toolchain, GCC
complains that some printk calls use %zu in connection with size_t
types since it resolves the typedefs to long unsigned int.
The problem is solved by using the GCC built-in __SIZE_TYPE__ if it
exists and define __SIZE_TYPE__ to long unsigned int otherwise.
