Michał Żygowski ede87184f8 nb/intel/sandybridge: Add support for DPR
Include DPR in the memory map calculations if enabled. DPR is required
for Intel TXT support.

TEST=Boot Debian 10 and see the DPR memory being reserved in E820 and
cbmem logs:
"BIOS-e820: [mem 0x000000007fc09000-0x00000000829fffff] reserved"
"TSEG base 0x80000000 size 8M"
"DPR base 0x7fd00000 size 3M"

Subrata Banik 6de8b42482 arch/x86: Refactor the SMBIOS type 17 write function
List of changes:
1. Create Module Type macros as per Memory Type
(i.e. DDR2/DDR3/DDR4/DDR5/LPDDR4/LPDDR5) and fix compilation
issue due to renaming of existing macros due to scoping the Memory
Type.
2. Use dedicated Memory Type and Module type for `Form Factor`
and `TypeDetail` conversion using `get_spd_info()` function.
3. Create a new API (convert_form_factor_to_module_type()) for
`Form Factor` to 'Module type' conversion as per `Memory Type`.
4. Add new argument as `Memory Type` to
smbios_form_factor_to_spd_mod_type() so that it can internally
call convert_form_factor_to_module_type() for `Module Type`
conversion.
5. Update `test_smbios_form_factor_to_spd_mod_type()` to
accommodate different memory types.
6. Skip fixed module type to form factor conversion using DDR2 SPD4
specification (inside dimm_info_fill()).

Refer to datasheet SPD4.1.2.M-1 for LPDDRx and SPD4.1.2.L-3 for DDRx.

Shelley Chen 4e9bb3308e Rename ECAM-specific MMCONF Kconfigs
Currently, the MMCONF Kconfigs only support the Enhanced Configuration
Access mechanism (ECAM) method for accessing the PCI config address
space.  Some platforms have a different way of mapping the PCI config
space to memory.  This patch renames the following configs to
make it clear that these configs are ECAM-specific:

- NO_MMCONF_SUPPORT --> NO_ECAM_MMCONF_SUPPORT
- MMCONF_SUPPORT --> ECAM_MMCONF_SUPPORT
- MMCONF_BASE_ADDRESS --> ECAM_MMCONF_BASE_ADDRESS
- MMCONF_BUS_NUMBER --> ECAM_MMCONF_BUS_NUMBER
- MMCONF_LENGTH --> ECAM_MMCONF_LENGTH

Please refer to CB:57861 "Proposed coreboot Changes" for more
details.

In cases where the existing code already accounts for null pointers, it

Angel Pons 6adbfa79aa nb/intel/haswell/pcie.c: Avoid needless death
Using `config_of(dev)` to access `dev->chip_info` will make coreboot die
if the latter is NULL, which is the case for devices detected at runtime
(i.e. not statically declared in the devicetree). Given that the code is
designed to work when the PEG config is all-zeroes (devicetree default),
dying because `dev->chip_info` is NULL is foolish and unwarranted.

Introduce a helper function that returns a pointer to devicetree config
when available, and otherwise returns a pointer to a zero-filled static
struct. In addition, avoid an out-of-bounds access in the very unlikely
case where the device's function is too large.

Tested on Asrock B85M Pro4, can now boot when `device pci 01.0 on end`
is commented out in its devicetree. Without this commit, it could not.

Angel Pons 6a2a5142d5 nb/intel/haswell: Fully handle GDXCBAR and EDRAMBAR
GDXCBAR and EDRAMBAR are accounted for when reporting resources to the
allocator, but they are not present in the DSDT. In addition, coreboot
does not enable either range, but MRC.bin sets up GDXCBAR and does not
disable it afterwards. Not reporting GDXCBAR in the DSDT can result in
resource conflicts, and not enabling EDRAMBAR can cause issues on CPUs
with eDRAM.

Enable both GDXCBAR and EDRAMBAR in coreboot code, and report these
ranges in the DSDT. This matches what Broadwell does. The value for
the `GDXC_BASE_ADDRESS` macro matches what MRC.bin programs as well.

Tested on Asrock B85M Pro4 with an i7-4770S (no eDRAM):
- Still boots
- EDRAMBAR is now enabled with base address of 0xfed80000
- GDXCBAR is still mapped with base address of 0xfed84000

Felix Held 2a29d45350 lib/hexdump: remove hexdump32 and use hexdump instead
hexdump and hexdump32 do similar things, but hexdump32 is mostly a
reimplementation that has additional support to configure the console
log level, but has a very unexpected len parameter that isn't in bytes,
but in DWORDs.
With the move to hexdump() the console log level for the hexdump is
changed to BIOS_DEBUG.

Do not use get_dram_base_mask to calculate system DRAM limits. Shift
operation around values operating on base and mask were causing
overflows and thus incorrect system DRAM limit. Another function
returning base and limit in KiB has been developed to avoid data loss.

Keep DRAM high base and limit in calculations only for Trinity where
the physical CPU address bits is 48. Although it is almost impossible
to have a non-zero value there, the platform would have to support
nearly 256GB of RAM.

Nico Huber 564413246d Revert "nb/intel/ironlake: Handle broken ME firmware"
This reverts commit 4447996cc5.

It looks like the patch repurposed the `memory_reserved_for_heci_mb`
variable as an indicator if the ME firmware is fine. The change to
setup_heci_uma() made it bail out early, even though the implementation
is obviously prepared to set things up even if the requested UMA
size is 0. This also leaves the code in an inconsistent state: The
second if's condition is always true.

Instead of counting consecutive matches (in `j`), check for a second
match directly in the control flow. Also, add some dedicated variables:

* `tap`: Keeps track of the tap value that resulted in a match and
         is eventually programmed into the hardware.

* `tap2`: Is just temporarily used to search for another edge.

Keeping `tap` sync'ed with the hardware has the benefit that we don't
need to read the programmed value back for later fixups.

There is no nb/amd/pi northbridge left in coreboot that could be paired

GPIO functionality that gets added by selecting
SOC_AMD_COMMON_BLOCK_BANKED_GPIOS is valid for all chips selecting it
and that code isn't valid for Bolton that uses the old GPIO 100
interface.

Angel Pons 936536cd2b nb/intel/common/fixed_bars.h: Add new read/write accessors
The {MCH,DMI,EP}BAR macros can be used for both reading and writing.
While this can sometimes be useful, compile-time overflow checking is
limited. Moreover, and-masks need to be bit-wise negated, which is easy
to forget and may result in spurious overflow warnings, and silencing
them with a cast also suppresses true integer overflow issues.

To address these limitations and for consistency with the existing MMIO
API (arch/mmio.h and device/mmio.h), these macros will be replaced with
prefixed wrappers around MMIO API functions. However, existing platform
code needs to be refactored, and the risk of introducing regressions is
substantial. To minimize the risk of breakage, the bulk of the platform
code changes will be verified using reproducible builds.

This patch introduces the new accessors, to be put to use in follow-ups.
These accessors are implemented as macros so that subsequent commits can
be verified using reproducible builds. They will be replaced with actual
functions after refactoring all platforms.

Angel Pons 6462cbb2c2 nb/intel/haswell: Ensure MCH has acked raminit
Haswell MRC.bin can return zero even when raminit did not complete
successfully. When this happens, the memory controller will not have
acknowledged raminit: the mc_init_done_ack bit in the MC_INIT_STATE_G
register will be zero, and memory accesses will lock up the system.

To handle this situation more gracefully, check the mc_init_done_ack bit
after running MRC. If the bit is not set, log a fatal error and halt.

Tested on Asrock B85M Pro4:
- With badly-seated DIMMs, MRC raminit fails and coreboot dies.
- After reseating the DIMMs, the board still boots successfully.

Angel Pons 90ae08922d nb/intel/haswell: Consolidate memory-down SPD handling
Mainboards do not need to know about `pei_data` to tell northbridge code
where to find the SPD data. Adjust `mb_get_spd_map` to take a pointer to
a struct instead of an array, and update all the mainboards accordingly.

Currently, the only board with memory-down in the tree is google/slippy.
Mainboard code now obtains the SPD index in `mb_get_spd_map` and adjusts
the channel population accordingly. Then, northbridge code reads the SPD
file and uses the index that was read in `mb_get_spd_map`, and copies it
to channel 0 slot 0 unconditionally. MRC only uses the first position of
the `spd_data` array, and ignores the other positions. In coreboot code,
`setup_sdram_meminfo` uses the data of each SPD index, so `copy_spd` has
to account for this.

Angel Pons 30931f5a4d sb/intel/lynxpoint: Move S3 check out of `early_pch_init`
Done for consistency with other platforms. This also drops redundant S3
resume logging, as `southbridge_detect_s3_resume` already prints it.

Tested on Asrock B85M Pro4, still boots and still resumes from S3.

Angel Pons 34be1be240 nb/intel/haswell: Finalize northbridge in ramstage
There's no need to finalize the northbridge in SMM. This also makes
unification with Broadwell easier.

Tested on Asrock B85M Pro4, still boots and registers get locked.

Angel Pons ae999503f6 nb/intel/haswell/pcie.c: Add missing pre-ASPM init
Add devicetree configuration parameters for mainboard-specific settings,
and provide reasonable defaults, which should usually be good enough.
This is based on Haswell SA Reference Code version 1.9.0 (Nov 2014).

Tested on Asrock B85M Pro4, registers now have the expected values.
