Since regions in bootmem are sorted by increasing base address, we may
bail out of the search loop as soon as the region_base is bigger than
the max address allowed.

They're listed in AUTHORS and often incorrect anyway, for example:
- What's a "Copyright $year-present"?
- Which incarnation of Google (Inc, LLC, ...) is the current
copyright holder?
- People sometimes have their editor auto-add themselves to files even
though they only deleted stuff
- Or they let the editor automatically update the copyright year,
because why not?
- Who is the copyright holder "The coreboot project Authors"?
- Or "Generated Code"?
Sidestep all these issues by simply not putting these notices in
individual files, let's list all copyright holders in AUTHORS instead
and use the git history to deal with the rest.

When <symbols.h> was first introduced, it only declared a handful of
regions and we didn't expect that too many architectures and platforms
would need to add their own later. However, our amount of platforms has
greatly expanded since, and with them the need for more special memory
regions. The amount of code duplication is starting to get unsightly,
and platforms keep defining their own <soc/symbols.h> files that need
this as well.
This patch adds another macro to cut down the definition boilerplate.
Unfortunately, macros cannot define other macros when they're called, so
referring to region sizes as _name_size doesn't work anymore. This patch
replaces the scheme with REGION_SIZE(name).
Not touching the regions in the x86-specific <arch/symbols.h> yet since
they don't follow the standard _region/_eregion naming scheme. They can
be converted later if desired.

Bounce buffers used to be used in those cases where the payload
might overlap coreboot.
Bounce buffers are a problem for rampayloads as they need malloc.
They are also an artifact of our x86 past before we had relocatable
ramstage; only x86, out of the 5 architectures we support, needs them;
currently they only seem to matter on the following chipsets:
src/northbridge/amd/amdfam10/Kconfig
src/northbridge/amd/lx/Kconfig
src/northbridge/via/vx900/Kconfig
src/soc/intel/fsp_baytrail/Kconfig
src/soc/intel/fsp_broadwell_de/Kconfig
The first three are obsolete or at least could be changed
to avoid the need to have bounce buffers.
The last two should change to no longer need them.
In any event they can be fixed or pegged to a release which supports
them.
For these five chipsets we change CONFIG_RAMBASE from 0x100000 (the
value needed in 1999 for the 32-bit Linux kernel, the original ramstage)
to 0xe00000 (14 Mib) which will put the non-relocatable x86
ramstage out of the way of any reasonable payload until we can
get rid of it for good.
14 MiB was chosen after some discussion, but it does fit well:
o Fits in the 16 MiB cacheable range coreboot sets up by default
o Most small payloads are well under 14 MiB (even kernels!)
o Most large payloads get loaded at 16 MiB (especially kernels!)
With this change in place coreboot correctly still loads a bzImage payload.
Werner reports that the 0xe00000 setting works on his broadwell systems.

The patch series ending in 64049be (lib/bootmem: Add method to walk OS
POV memory tables) expanded the bootmem framework to also keep track of
memory regions that are only relevant while coreboot is still executing,
such as the ramstage code and data. Mixing this into the exsting bootmem
ranges has already caused an issue on CONFIG_RELOCATEABLE_RAMSTAGE
boards, because the ramstage code in CBMEM is marked as BM_RAMSTAGE
which ends up getting translated back to LB_RAM in the OS tables. This
was fixed in 1ecec5f (lib/bootmem: ensure ramstage memory isn't given to
OS) for this specific case, but unfortunately Arm boards can have a
similar problem where their stack space is sometimes located in an SRAM
region that should not be made available as RAM to the OS.
Since both the resources made available to the OS and the regions
reserved for coreboot can be different for each platform, we should find
a generic solution to this rather than trying to deal with each issue
individually. This patch solves the problem by keeping the OS point of
view and the coreboot-specific ranges separate from the start, rather
than cloning it out later. Ranges only relevant to the coreboot view
will never touch the OS-specific layout, to avoid the problem of losing
information about the original memory type of the underlying region that
needs to be restored for the OS view. This both supersedes the
RELOCATABLE_RAMSTAGE fix and resolves the problems on Arm boards.

Introduce new bootmem tags to allow more fine grained control over buffer
allocation on various platforms. The new tags are:
BM_MEM_RAMSTAGE : Memory where any kind of boot firmware resides and that
should not be touched by bootmem (by example: stack,
TTB, program, ...).
BM_MEM_PAYLOAD : Memory where any kind of payload resides and that should
not be touched by bootmem.
Starting with this commit all bootmem methods will no longer see memory
that is used by coreboot as usable RAM.
Bootmem changes:
* Introduce a weak function to add platform specific memranges.
* Mark memory allocated by bootmem as BM_TAG_PAYLOAD.
* Assert on failures.
* Add _stack and _program as BM_MEM_RAMSTAGE.
ARMv7 and ARMv8 specific changes:
* Add _ttb and _postram_cbfs_cache as BM_MEM_RAMSTAGE.
ARMv7 specific changes:
* Add _ttb_subtables as BM_MEM_RAMSTAGE.

that, only mark bootmem initialized when bootmem_write_memory_table() is
called. Any other calls to bootmem before that will report an error on

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.
