b4f47e8067 nb/intel/haswell: Move SPD addresses to devicetree
Introduce a sandybridge-style devicetree setting for SPD addresses,
and use it instead of runtime code in mb_get_spd_map() for all
haswell boards without CONFIG(HAVE_SPD_IN_CBFS) - effectively all
boards except google/slippy.

Patch also covers recently added Z97 boards using Broadwell MRC.

Also update util/autoport to match.

abuild passes for all affected boards.
autoport builds, but otherwise untested.

ee12634872 nb/sandybridge,sb/bd82x6x: Configure USB from southbridge devicetree
Transfer all USB responsibilities to southbridge/intel/bd82x6x,
using one set of USB port configuration supplied by mainboards
in the southbridge section of their devicetree.

For MRC raminit, export southbridge_fill_pei_data() as a hook for
southbridge code to implement. With new code via this hook, bd82x6x
fills pei_data based on this one set of USB port config.

For native raminit, early_usb_init() now goes directly to the devicetree
and no longer get passed an address to it.

TEST=abuild passes for all affected boards. All USB ports still work
on asus/p8x7x-series/v/p8z77-m.

317a982ddb nb/intel/sandybridge: Refactor pei_data building code
Incorporate fixed constants and simple data members into struct
pei_data as it gets initialized and make more use of existing helpers.

Drop northbridge_fill_pei_data() as it gets replaced entirely.

Gut southbridge_fill_pei_data() in preparation for having southbridge
code fill in USB-related members.

This is to make the code easier to maintain, and realizes small savings
in compiled code size too.

c770ad6246 cpu/x86: Make 1GB paging the default
This patch flips the polarity of CONFIG_USE_1G_PAGES_TLB into
CONFIG_NEED_SMALL_2MB_PAGE_TABLES which is off by default, meaning
CPUs added in the future will automatically build the smaller 1GB pages.
We can expect support for this feature to be available on all future CPU
generations (with the possible exception of embedded edge cases), so
this default setting should make mistakes less likely and keep
maintenance effort lower. (Besides, enabling the support where it
doesn't work fails fast, whereas keeping it disabled where it could work
is an inefficiency that can easily go overlooked for a long time.)

While this is technically a CPU feature, not a northbridge feature, we
support a lot more individual CPUs than northbridges in the pre-SoC era,
and they tend to be closely coupled anyway. So select the option at the
northbridge level for older CPUs to keep things simpler.

SMBus mux, which makes the DIMM SPDs inaccessible. Given that the SPD

side-effects, simply move the call to `mb_post_raminit_setup()` after
the call to `setup_sdram_meminfo()`.

This patch disables legacy VGA cycles for iGPU, under such

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.

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.

80c79a5dc3 device/device.h: Drop multiple links
Multiple links are unused throughout the tree and make the code more
confusing as an iteration over all busses is needed to get downstream
devices. This also not done consistently e.g. the allocator does not
care about multiple links on busses. A better way of dealing multiple
links below a device is to feature dummy devices with each their
respective bus.

This drops the sconfig capability to declare the same device multiple
times which was previously used to declare multiple links.

This issue is also seen in the release notes generation script where
Makefiles get renamed before running cloc.

sets hole_startk to the actual value that then gets used by

This APU is always a single-node and since we're in ramstage when
domain_read_resources gets called, there's DRAM on this node, so no need
to check for this. To be extra sure, also initialize basek and limitk
before calling get_dram_base_limit with pointers to those as arguments.
This won't be necessary for the code to work as intended, but will
probably keep the compiler from complaining. Also move the declaration
of basek, limitk and sizek to the beginning of the function.
