For x86 systems employing CONFIG_LATE_CBMEM_INIT, set_top_of_ram() is
called in ramstage to note the upper address of the 32-bit address
space. This in turn is consumed by cbmem. However, in this scenario
cbmem_top() cannot always be relied upon because get_top_of_ram()
doesn't return the same value provided to set_top_of_ram().
To fix the inconsistency in ramstage save the value passed in
to set_top_of_ram() and defer to it as the return value for
cbmem_top().

As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.
However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.
util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

The imd (internal memory database) library provides a way to
track memory regions by assigning ids to each region. The implementation
is a direct descendant of dynamic cbmem. The intent is to replace
the existing mechanisms which do similar things: dynamic cbmem, stage
cache, etc.
Differences between dynamic cbmem and imd:
- All structures/objects are relative to one another. There
are no absolute pointers serialized to memory.
- Allow limiting the size of the idm. i.e. provide a maximum
memory usage.
- Allow setting the size of the root structure which allows
control of the number of allocations to track.

This is the same location as CBMEM_RESUME_BACKUP - the two aren't used

documentation that actually said that this location was free to use, and
didn't need to be restored after use in S3 resume, but it looks like
the DOS boot vector gets loaded juat above this location, so it SHOULD
be ok. The alternative is to copy the memory out and store it in cbmem
until we're ready to restore it.
2) When a request for the pointer to a CAR variable comes in, pass back

3) Skip the memcopy of the CAR Data. The CAR variables do not

The replacement function confirms CBMEM TOC is wiped clean on power
cycles and resets. It also introduces compatibility interface to ease
up transition to DYNAMIC_CBMEM.

CBMEM console buffer size is adjustable in menuconfig, but this would
not correctly adjust the overall allocation made for CBMEM.
HIGH_MEMORY_SIZE is aligned to 64kB and definitions are moved down in
the header file as HIGH_MEMORY_SIZE is not used with DYNAMIC_CBMEM.
Try to continue boot even if CBMEM cannot be created. This error would
only occur during development of new ports anyways and more log output
is better.

Add support for Sandybridge and Ivybridge using the Intel FSP.
The FSP is different enough to warrant its own source files.
This source handle the majority of FSP interaction.
"Intel® Firmware Support Package (Intel® FSP) provides key
programming information for initializing Intel® silicon and can be
easily integrated into a boot loader of the developer’s choice.
It is easy to adopt, scalable to design, reduces time-to-market, and

For both romstage and ramstage, this calls an arch-specific function
get_cbmem_table() to resolve the base and size of CBMEM region. In ramstage,
the result is cached as the query may be relatively slow involving multiple PCI
configuration reads.
For x86 CBMEM tables are located right below top of low ram and
have fixed size of HIGH_MEMORY_SIZE in EARLY_CBMEM_INIT implementation.

We can postpone the call to set_top_of_ram_once() outside the
loops and make just one call instead.
As set_top_of_ram() is now only called once, it is no longer
necessary to check if high_tables_base was already set.
