Aaron Durbin bf1e481944 lib: remove FLASHMAP_OFFSET config variable
The FLASHMAP_OFFSET config variable is used in lib/fmap.c, however
the fmdtool creates a fmap_config.h with a FMAP_OFFSET #define.
Those 2 values are not consistent. Therefore, remove the Kconfig
variable and defer to the #define generated by fmdtool.

Furquan Shaikh 1e162bf8bd lib/prog_loaders: Allow platforms to skip stage cache
Before multi-CBFS support was added, x86 platforms cached their
ramstage in TSEG so that it could be re-used on the resume
path. However, more resources/assets are being put in cbfs that are
utilized during ramstage. Just caching ramstage does not mean that
correct cbfs region is used for all the data. Thus, provide an option
to allow platforms to skip caching any component for resume.

Furquan Shaikh 94b18a1757 xip: Do not pass --xip for early stages if CAR supports code execution
On modern x86 platforms like apollolake, pre-RAM stages verstage and
romstage run within the cache-as-ram region. Thus, we do not need to
pass in the --xip parameter to cbfstool while adding these
stages. Introduce a new Kconfig variable NO_XIP_EARLY_STAGES which is
default false for all x86 platforms. Apollolake selects this option
since it supports code execution with CAR.

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).

This patch generalizes the approach previously used for ARM32
TTB_SUBTABLES to "auto-detect" whether a certain region was defined in
memlayout.ld. This allows us to get rid of the explicit Kconfig for the

confusion when setting up future boards.

(Removing armv4/bootblock_simple.c because it references this Kconfig
and it is a dead file that I just forgot to remove in CL:12076.)

Martin Roth 59ff3400b0 Kconfig: Move defaults for CBFS_SIZE
We want the question for CBFS size to be next to the rom size in the
mainboard directory, but that doesn't seem to work for how people
want to set the defaults.  Instead of having the list of exceptions
to the size, just set the defaults at the end of kconfig.

- Move the defaults for chipsets not setting HAVE_INTEL_FIRMWARE into
the chipset Kconfigs (gm45, nehalem, sandybridge, x4x)
- Override the default for HAVE_INTEL_FIRMWARE on skylake.
- Move the HAVE_INTEL_FIRMWARE default setting into the firmware
Kconfig file
- Move the location of the default CBFS_SIZE=ROM_SIZE to the end of
the top level kconfig file, while leaving the question where it is.

Test=rebuild Kconfig files before and after the change, verify that
they are how they were intended to be.

Note: the Skylake boards actually changed value, because they were
picking up the 0x100000 from HAVE_INTEL_FIRMWARE instead of the
0x200000 desired.  This was due to the SOC_INTEL_SKYLAKE being after
the HAVE_INTEL_FIRMWARE default.  Affected boards were:
Google chell, glados, & lars and Intel kunimitsu.

Aaron Durbin 87c9faeb4c chromeos/vboot: provide support for x86 memory init verification
For x86 systems which resume through the reset vector one needs to
ensure the the RW slot taken at resume time matches the one at
boot time. The reason is that any assets pulled out of the boot
media need to match how the platform previously booted. To do
that one needs obtain the hash digest of the chosen slot, and it
needs to be saved in a secure place on the normal boot path. On
resume one needs to retrieve the hash digest back to compare it
with the chosen slot. If they don't match resuming won't be
possible.

BUG=chrome-os-partner:46049
BRANCH=glados
TEST=Suspended and resumed on chell. Also, tested with an EC build
     which returns a bad hash to ensure that is properly caught.

One special case is google/veyron's chromeos.fmd, which is used for a

Set aside 128K for the bootblock on non-x86 systems (where the COREBOOT
region ends up at the beginning of flash). This becomes necessary
because we're working without a real cbfs master header (exists for
transition only), which carved out the space for the offset.

Decoding the faulting address:

               1        Signal State Bit Map = [0] = 0x1

Therefore, the error appears to be triggered by an upstream C1E request.

This was eventually traced to concurrent access to the SP5100's SPI Flash controller by
multiple APs during startup.  Calls to the nvram read functions get_option and read_option
call CBFS functions, which in turn make near-simultaneous requests to the SPI Flash
controller, thus placing the SP5100 in an invalid state.  This limitation is not documented
in any public AMD errata, and was only discovered through considerable debugging effort.

Patrick Georgi 8a3592eec3 build system: Switch to fmap based firmware layout
We still add a master header for compatibility purposes, and the default
layouts don't cover anything non-coreboot (eg. IFD regions) yet.

The default layouts can be overridden by specifying an fmd file, from
which the fmap is generated.

Future work:
- map IFD regions to fmap regions
- non-x86: build minimalistic trampolines that jump into the first cbfs
  file, so the bootblock can be part of CBFS instead of reserving a
  whole 64K for it.
- teach coreboot's cbfs code to work without the master header
- teach coreboot's cbfs code to work on different fmap regions

HAS_PRECBMEM_TIMESTAMP_REGION was dependent on COLLECT_TIMESTAMPS,

the code may only be used when collecting timestamps, the HAS prefix

This fix could also be done by adding 'if COLLECT_TIMESTAMPS' everywhere

Julius Werner 66a476ad5f arm64: Implement generic stage transitions for non-Tegra SoCs
The existing arm64 architecture code has been developed for the Tegra132
and Tegra210 SoCs, which only start their ARM64 cores in ramstage. It
interweaves the stage entry point with code that initializes a CPU (and
should not be run again if that CPU already ran a previous stage). It
also still contains some vestiges of SMP/secmon support (such as setting
up stacks in the BSS instead of using the stage-peristent one from
memlayout).

This patch splits those functions apart and makes the code layout
similar to how things work on ARM32. The default stage_entry() symbol is
a no-op wrapper that just calls main() for the current stage, for the
normal case where a stage ran on the same core as the last one. It can
be overridden by SoC code to support special cases like Tegra.

The CPU initialization code is split out into armv8/cpu.S (similar to
what arm_init_caches() does for ARM32) and called by the default
bootblock entry code. SoCs where a CPU starts up in a later stage can
call the same code from a stage_entry() override instead.

The Tegra132 and Tegra210 code is not touched by this patch to make it
easier to review and validate. A follow-up patch will bring those SoCs
in line with the model.

Julius Werner 86fc11d0c9 arm/arm64: Generalize bootblock C entry point
When we first added ARM support to coreboot, it was clear that the
bootblock would need to do vastly different tasks than on x86, so we
moved its main logic under arch/. Now that we have several more
architectures, it turns out (as with so many things lately) that x86 is
really the odd one out, and all the others are trying to do pretty much
the same thing. This has already caused maintenance issues as the ARM32
bootblock developed and less-mature architectures were left behind with
old cruft.

This patch tries to address that problem by centralizing that logic
under lib/ for use by all architectures/SoCs that don't explicitly
opt-out (with the slightly adapted existing BOOTBLOCK_CUSTOM option).
This works great out of the box for ARM32 and ARM64. It could probably
be easily applied to MIPS and RISCV as well, but I don't have any of
those boards to test so I'll mark them as BOOTBLOCK_CUSTOM for now and
leave that for later cleanup.

Timothy Pearson 3bfd7cc61e drivers/pc80: Rework normal / fallback selector code
Per IRC and Gerrit discussion, the normal / fallback
selector code is a rather weak spot in coreboot, and
did not function correctly for certain use cases.

Rework the selector to more clearly indicate proper
operation, and also remove dead code.  Also tentatively
abandon use of RTC bit 385; a follow-up patch will
remove said bit from all affected mainboards.

The correct operation of the fallback code selector
approximates that of a power line recloser, with
a user option to attempt normal boot that can be
cleared by firmware, but never set by firmware.
Additionally, if cleared by user, the fallback
path should always be used on the next reboot.

Alexandru Gagniuc ecf2eb463f sandybridge ivybridge: Treat native init as first class citizen
This is a sad story. We have three different code paths for
sandybridge and ivybridge: proper native path, google MRC path, and,
everyone's favorite: Intel FSP path. For the purpose of this patch,
the FSP path lives in its own little world, and doesn't concern us.

Since MRC was first, when native files and variables were added, they
were suffixed with "_native" to separate them from the existing code.
This can cause confusion, as the suffix might make the native files
seem parasitical.

This has been bothering me for many months. MRC should be the
parasitical path, especially since we fully support native init, and
it works more reliably, on a wider range of hardware. There have been
a few board ports that never made it to coreboot.org because MRC would
hang.

gigabyte/ga-b75m-d3h is a prime example: it did not work with MRC, so
the effort was abandoned at first. Once the native path became
available, the effort was restarted and the board is now supported.

In honor of the hackers and pioneers who made the native code
possible, rename things so that their effort is the first class
citizen.
