hostbridge.asl
Lower 20bits of TOLUD and TOLM registers include 19 reserved bits and
1 lock bit. If lock bit is set, then systemagent.asl would end up
reporting the base address of low MMIO incorrectly i.e. off by 1.
This change masks the lower 20 bits of TOLUD and TOM registers when
exposing it in the ACPI tables to ensure that the base address of low
MMIO region is reported correctly.

This change updates hostbridge.asl to use ASL2.0 syntax. This

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.

It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.
This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

On Broadwell, this reduces the number of 'remarks' in the IASL build
from 222 to 3.
Fixes these remarks:
Object is not referenced (Name is within method [_CRS])
The ACPI compiler is trying to be helpful in letting us know
that we're not using various fields in the MCRS ResourceTemplate
when we define it inside of the _CRS method. Since we're not
intending to use those objects in the method, it shouldn't be an
issue, but the warning is annoying and can mask real issues.
Moving the creation of the MCRS object to outside of the CRS
method and referencing it from there solves this problem.
This change was made for fsp_baytrail in commit 2eaa0d49

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.

Several of the intel platforms define the region reserved
for PCI memory resources in a location where it overlaps
with the MMIO (MCFG) region.
Using the memory map from mohon_peak as an example:
0. 0000000000000000-0000000000000fff: CONFIGURATION TABLES
1. 0000000000001000-000000000009ffff: RAM
2. 00000000000a0000-00000000000fffff: RESERVED
3. 0000000000100000-000000007fbcffff: RAM
4. 000000007fbd0000-000000007fbfffff: CONFIGURATION TABLES
5. 000000007fc00000-000000007fdfffff: RESERVED
6. 00000000e0000000-00000000efffffff: RESERVED
7. 00000000fee00000-00000000fee00fff: RESERVED
8. 0000000100000000-000000017fffffff: RAM
The ACPI table describing the space set aside for PCI memory
(not to be confused with the MMIO config space) is defined
as the region from BMBOUND (the top of DRAM below 4GB) to
a hardcoded value of 0xfebfffff. That region would overlap
the MMIO region at 0xe0000000-0xefffffff. For rangeley
the upper bound of the PCI memory space should be set
to 0xe0000000 - 1.
The MCFG regions for several of the affected chipsets are:
rangeley 0xe0000000-0xefffffff
baytrail 0xe0000000-0xefffffff
haswell 0xf0000000-0xf3ffffff
sandybridge 0xf8000000-0xfbffffff

The existing code generated invalid ACPI processor objects
if the core number was greater than 9. The first invalid
object instance was autocorrected by Linux, but subsequent
instances conflicted with each other, leading to a failure
to boot if more than 10 CPU cores were installed.
The modified code will function with up to 99 cores.

On those chipsets the pins are just a legacy concept. Real interrupts are
messages on corresponding busses or some internal logic of chipset.
Hence interrupt routing isn't anymore board-specific (dependent on layout) but
depends only on configuration.
Rather than attempting to sync real config, ACPI and legacy descriptors, just
use the same interrupt routing per chipset covering all possible devices.
The only part which remains board-specific are LPC and PCI interrupts.
Interrupt balancing may suffer from such merge but:
a) Doesn't seem to be the case of this map on current systems
b) Almost all OS use MSI nowadays bypassing this stuff completely
c) If we want a good balancing we need to take into account that e.g.
wlan card may be placed in a different slot and so would require complicated
balancing on runtime. It's difficult to maintain with almost no benefit.

as the kernel powers devices off on suspend and brings them
back online in resume.
This also adds a mutex around the TDP operations since it is
split across two methods and can't just rely on being Serialized.

The required power MSRs are mirrored in MCHBAR so
it is possible to configure TDP at runtime via ASL.
This adds the required fields and a set of methods to
configure "TDP down" and "TDP nominal". It explicitly
does not support "TDP up" at the moment.
PSSS: method is added to assist in searching the _PSS
table for the appropriate entry that corresponds to the
desired max non-turbo ratio.
STND: Set TDP Down from Nominal. This will limit CPU to
the TDP down configuration by sequencing the required
changes in the right order.
STDN: Set TDP Nominal from Down. This will set the CPU
back to nominal configuration by sequencing the required
changes in the correct (reverse) order.
This does not introduce any functional changes and must
be paired with additional changes to be useful.
The current configured TDP can be checked to see that
the transition to/from a desired level is successful.
