4e722d0766 nb/intel/ironlake: Split out HECI code out of raminit
Move HECI code out of raminit.c into a separate raminit_heci.c file. To
preserve reproducibility, use a temporary .c include. This will be gone
in a follow-up.

Tested with BUILD_TIMELESS=1, Packard Bell MS2290 remains identical.

e9665959ed treewide: Remove "ERROR: "/"WARN: " prefixes from log messages
Now that the console system itself will clearly differentiate loglevels,
it is no longer necessary to explicitly add "ERROR: " in front of every
BIOS_ERR message to help it stand out more (and allow automated tooling
to grep for it). Removing all these extra .rodata characters should save
us a nice little amount of binary size.

This patch was created by running

  find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';'

and doing some cursory review/cleanup on the result. Then doing the same
thing for BIOS_WARN with

  's/printk\(\s*BIOS_WARNING,\s*"WARN(ING)?: /printk\(BIOS_WARNING, "/gi'

a4d033a66d nb/amd/pi/00730F01/iommu: call pci_dev_set_resources directly
There is no need to have the iommu_set_resources function which only
calls pci_dev_set_resources, so assign pci_dev_set_resources directly to
the set_resources function pointer field in the iommu_ops struct.

ddf137f822 nb,soc/amd/*/iommu: fix comment about IOMMU MMIO resource
This comment was added with the AMD family 15h Trinity IOMMU support in
commit 88ebbeb7e2 and looks like a copy of
the comment about the subtractive decode ranges in the LPC device. The
IOMMU doesn't have any subtractively decoded I/O or MMIO ranges and this
is also not what the code does. This resource is the MMIO region to
configure the IOMMU instead, so fix the comment in all copies of the
IOMMU support code.

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.

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.

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.

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

88a0ce6e11 nb/amd/{agesa,pi}: Avoid overflows during DRAM calculation
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.

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.

2bb361f0f5 nb/intel/x4x: Refactor sync DLL programming (part 2)
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.

70d1c723f7 sb/amd/pi/hudson: remove unused Bolton PI FCH code
There is no nb/amd/pi northbridge left in coreboot that could be paired
with the Bolton FCH, since the remaining nb/amd/pi northbridges all use
an integrated FCH (Avalon on Mullins and Kern on Carrizo) while Bolton
is a discrete FCH. I ran into this when verifying if the common soc/amd
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.

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.

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.

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.

There are platforms that support error correction types other than

It is assumed that `struct memory_info` is packed to save space. Thus,
use `uint8_t` instead of an enum type (which are usually 4 bytes wide).

12d3768ec5 nb/intel/pineview: Clean up FIXMEs in raminit
Using MCHBAR32_AND_OR() in these two cases changes the order of
additions slightly. Originally, the MCHBAR offset and the base
register offset (0x5a4/0x5b4) were added first. Due to the added
parentheses in the register macros, now the complete register
offset is calculated first and then added to MCHBAR. Associativity
tells us that this doesn't change the result.

Changes in the resulting binary were verified manually on the
object file.

0f30063abf soc/intel/broadwell: Conditionally skip PRE_GRAPHICS_DELAY
It was commented that the need for the delay was mainly related
to external displays and only with VBIOS execution. Move the
delay such that it is done only when we actually need to execute
the VBIOS aka option rom.

A delay is currently only defined for librem/purism_bdw in
its Kconfig. As the description of the issue sounds like it
would equally happen on other platforms when VBIOS is involved,
promote the Kconfig visible option to global scope.

This cosmetic change does 2 things:
- change bitwise shifting to division
- Make the division by / KiB explicit for fixed legacy ranges like
  0xa0000.

the new resource allocator that will make use of any unclaimed space.

7519ca42b5 nb/intel/sandybridge: Clarify command timing calculation
Command timing is the absolute value of the most negative `pi_coding`
value across all ranks, or zero if there are no negative values. Use the
MAX() macro to ease proving that `cmd_delay` can never be negative, and
then drop the always-false underflow check.

The variable type for `cmd_delay` still needs to be signed because of
the comparisons with `pi_coding`, which is a signed value. Using an
unsigned type would result in undefined and also undesired behavior.

0a7d99c089 nb/intel/sandybridge: Fix handling of clock timing
Clock is a differential signal and propagates faster than command and
control, therefore its timing needs to be offset with `pi_code_offset`.
It is also a periodic signal, so it can safely wrap around.

To avoid potential undefined behavior, make `clk_delay` signed. It makes
no difference with valid values, because the initial value can be proven
to never be negative and `pi_code_offset` is always positive. With this
change, it is possible to add an underflow check, for additional sanity.
