Aaron Durbin 8198c678f7 arch/x86: always use _start as entry symbol for all stages
Instead of keeping track of all the combinations of entry points
depending on the stage and other options just use _start. That way,
there's no need to update the arch/header.ld for complicated cases
as _start is always the entry point for a stage.

Aaron Durbin 4330a9c8e5 arch/x86: rename reset_vector -> _start
In order to align the entry points for the various stages
on x86 to _start one needs to rename the reset_vector symbol.
The section is the same; it's just a symbol change.

Andrey Petrov ccd300b4b4 arch/x86: Allow soc/chipset to set linking address
Until recently x86 romstage used to be linked at some default
address. The address itself is not meaningful because the code
was normally relocated at address calculated during insertion
in CBFS. Since some newer SoC run romstage at CAR it became
useful to link romstage code at some address in CAR and avoid
relocation during build/run time altogether.

Aaron Durbin f8468d43e0 cpu/x86/16bit: rename _start -> _start16bit
In order to avoid collisions with other _start symbols while
grepping and future ones be explicit about which _start this
one is: the 16-bit one only used by the reset vector in the
bootblock.

Subrata Banik b7e69a2e56 Skylake: Support Intel Speed Shift Technology based on config
Intel Speed Shift Technology is a new mechanism that replaces
Legacy P-state. ISST allows OS hints about energy/performance

1. Optimization frequency seclection for low residency workloads,
no longer a static knee point.
2. Optimized frequency selection for best energy to performance
trade offs.
3. Kick down frequency (from idle) fpr best responsiveness while

Coreboot's responsiblity is to configure MSR 0x1AA ISST_EN bits
which will reflect in CPUID.06h:EAX[Bit 7] that driver checkes
and enable HWP accordingly.

The FBC hardware for skylake does not have access to the bios_reserved
range so it always assumes 8MB is used and so the kernel will
therefore need to avoid using the last 8MB of the stolen window.
With the default stolen size of 32MB(-8MB) there is not enough space
for FBC to work with a high resolution panel.

Patrick Rudolph d912f1d4f9 nb/intel/sandybridge/raminit: Adjust timB to prevent overflow
Improved version of
I1a115a45d5febf351d89721ece79eaf43f7ee8a0

The first version wasn't well tested due to the lack of hardware
and it was to aggressive.

With timC being direct function of timB's 6 LSBs it's critical to match
timC and timB.
Some tests increments the value of timB by a small value,
which might cause the 6bit value to overflow, if it's close
to 0x3F.
Increment the value by a small offset if it's likely
to overflow, to make sure it won't overflow while running
tests and bricks the system due to a non matching timC.

In comparission to the first attempt, only 4 out of 128 timB values
are considered bad.

Needs test on real hardware !

Fixes a "edge write discovery failed" on my test system.

Test system:
 * Intel IvyBridge
 * Gigabyte GA-B75M-D3H

Julius Werner 09f2921b5d cbfs: Add LZ4 in-place decompression support for pre-RAM stages
This patch ports the LZ4 decompression code that debuted in libpayload
last year to coreboot for use in CBFS stages (upgrading the base
algorithm to LZ4's dev branch to access the new in-place decompression
checks). This is especially useful for pre-RAM stages in constrained
SRAM-based systems, which previously could not be compressed due to
the size requirements of the LZMA scratchpad and bounce buffer. The
LZ4 algorithm offers a very lean decompressor function and in-place
decompression support to achieve roughly the same boot speed gains
(trading compression ratio for decompression time) with nearly no
memory overhead.

For now we only activate it for the stages that had previously not been
compressed at all on non-XIP (read: non-x86) boards. In the future we
may also consider replacing LZMA completely for certain boards, since
which algorithm wins out on boot speed depends on board-specific
parameters (architecture, processor speed, SPI transfer rate, etc.).

BRANCH=None
BUG=None
TEST=Built and booted Oak, Jerry, Nyan and Falco. Measured boot time on
Oak to be about ~20ms faster (cutting load times for affected stages
almost in half).

Stages are inconsistent with other memlayout regions in that they don't

_eprogram, but that always only refers to the current stage and
_eprogram marks the actual end of the executable's memory footprint, not
the end of the area allocated in memlayout. Both of these are sometimes
useful to know, so let's add another set of symbols that allow the stage
areas to be treated more similarly to other regions.
