78ba7a7865 device/dram/ddr{3,4}: Rename spd_raw_data for specific DDR
Rename different spd_raw_data[] for DDR3 and DDR4.
This is to solve the conflict when we include both "ddr3.h" and ddr4.h"
for example here: src/device/dram/spd.c.
Otherwise, it won't compile as DDR3 and DDR4 have different
spd_raw_data[] size.

8b5aacca3f nb/intel/gm45: Call mb_post_raminit_setup() later
The only implementations of `mb_post_raminit_setup()` in the tree are
found in Lenovo ThinkPads. These boards use this function to toggle a
SMBus mux, which makes the DIMM SPDs inaccessible. Given that the SPD
data is needed in `setup_sdram_meminfo()` and that there are no other
side-effects, simply move the call to `mb_post_raminit_setup()` after
the call to `setup_sdram_meminfo()`.

TEST=Verify SMBIOS Type 17 information for lenovo/x200 is correct.

6f75dd0fd0 sandybridge,haswell,broadwell: Use DIV_ROUND_CLOSEST macro
Integer division in C truncates toward zero. When the dividend and the
divisor are positive, one can add half of the divisor to the dividend to
round the division result towards the closest integer. We already have a
macro in commonlib to do just that, so put it to good use.

Tested with BUILD_TIMELESS=1, coreboot images for the Asus P8Z77-V LX2
and the Asrock B85M Pro4 do not change.

1e2821882f nb/haswell: Disable iGPU when dGPU is used
This is usually is handled by Haswell mrc.bin, disabling VGA
decode on the iGPU when a dGPU is installed. However, Broadwell
mrc.bin does not, so the iGPU and dGPU are both enabled.

This patch disables legacy VGA cycles for iGPU, under such
conditions. It has been tested on Broadwell mrc.bin when
using a graphics card on Dell OptiPlex 9020 SFF (currently
under review at this time of writing, submitted by Mate
Kukri).

This patch has also been tested when Haswell mrc.bin is used,
and there are seemingly no breaking changes caused by it.

b506020076 commonlib: Change GCD function to always use 64 bits
It seems that we have some applications where we need to calculate a GCD
in 64 bits. Now, we could instantiate the algorithm multiple times for
different bit width combinations to be able to use the most efficient
one for each problem... but considering that the function usually only
gets called once per callsite per stage, and that software emulation of
64-bit division on 32-bit systems doesn't take *that* long either, we
would probably usually be paying more time loading the second instance
of the function than we save with faster divisions. So let's just make
things easy and always do it in 64-bit and then nobody has to spend time
thinking on which version to call.

de37109767 lib: Move IP checksum to commonlib
This patch moves the IP checksum algorithm into commonlib to prepare for
it being shared with libpayload. The current implementation is ancient
and pretty hard to read (and does some unnecessary questionable things
like the type-punning stuff which leads to suboptimal code generation),
so this reimplements it from scratch (that also helps with the
licensing).

This algorithm is prepared to take in a pre-calculated "wide" checksum
in a machine-register-sized data type which is then narrowed down to 16
bits (see RFC 1071 for why that's valid). This isn't used yet (and the
code will get optimized out), but will be used later in this patch
series for architecture-specific optimization.

bfb11bec3b include/device/device.h: Remove CHIP_NAME() macro
Macros can be confusing on their own; hiding commas make things worse.
This can sometimes be downright misleading. A "good" example would be
the code in soc/intel/xeon_sp/spr/chip.c:

CHIP_NAME("Intel SapphireRapids-SP").enable_dev = chip_enable_dev,

This appears as CHIP_NAME() being some struct when in fact these are
defining 2 separate members of the same struct.

It was decided to remove this macro altogether, as it does not do
anything special and incurs a maintenance burden.

2.  Remove post-mainboard SPD data sanitization code in raminit_mrc.c,

3.  Remove old prototypes from raminit_native.h
4a. Drops raminit_native.h from raminit.c, as individual headers

4b. Drop another header from raminit.c IWYU identified as unneeded.

1e9601c5ef nb/intel/sandybridge: Standardize MRC vs. native SPD mapping API
Changes both MRC and native raminit code path to get SPD mapping
from one place.

Boards with all memory socketed specify their mappings in a
devicetree setting introduced in commit 5709e03613
("nb/intel/sandybridge: Migrate MRC settings to devicetree") back in
May 2019 but remains unused as of this patch. This setting
will now hold raw SMBus addresses, and MRC raminit gets code to
translate them into a representation MRC expects.

Boards with soldered down memory (specifically with HAVE_SPD_IN_CBFS
in their board Kconfig), with or without socketed memory, specify
their layouts in mb_get_spd_map() as used by Haswell boards, where
they access hardware GPIO straps to select which SPD data to use.

This harmonizes the way boards specify their SPD layouts across
Haswell/SNB/IVB boards whether using MRC or native raminit. Going
forward they only need to specify the layout in one place. (Going
forward the devicetree setting should be backported to Haswell,
once we get native raminit working there.)

With this, northbridge code is now fully responsible for loading
all SPD data, be it from CBFS or SMBus.

To avoid breakage, transition will happen in stages:

1. This patch gets all the code in, and implements weak stubs that
maintain existing code and data flow (i.e. mainboards still populate
final SPD layout data). At this point devicetree already uses new
representation, but is still unused meaning no breakage.

2. Follow-up patch(es) remove mainboard_get_spd() from mainboards, and
replace it with mb_get_spd_map() or devicetree values (as appropriate)
with converted SPD info. The "weak" mainboard_get_spd() with new logic
takes over. Boards go Haswell Style at this point. Boards with MRC
raminit also lose code to fill in SPD data, allowing new data to take
hold.

3. Clean-up patch removes the weak functions and public prototypes re
mainboard_get_spd(), making it internal to northbridge. Changeover is
complete.

052fb7c451 x86: Add pre-memory stages CBFS cache scratchpad support
Having a CBFS cache scratchpad offers a generic way to decompress CBFS
files through the cbfs_map() function without having to reserve a
per-file specific memory region.

This commit introduces the x86 `PRERAM_CBFS_CACHE_SIZE' Kconfig to set
the pre-memory stages CBFS cache size.  A cache size of zero disables
the CBFS cache feature.  The default value is 16 KB which seems a
reasonable minimal value enough to satisfy basic needs such as the
decompression of a small configuration file. This setting can be
adjusted depending on the platform needs and capabilities.

We have set this size to zero for all the platforms without enough
space in Cache-As-RAM to accommodate the default size.

To help identify the licenses of the various files contained in the

.c and .h files. This extends that practice to Makefiles.

Any file in the coreboot project without a specific license is bound
to the license of the overall coreboot project, GPL Version 2.

This patch adds the GPL V2 license identifier to the top of all
makefiles in the commonlib, console, northbridge, security, and
southbridge directories that don't already have an SPDX license line
at the top.
