Julius Werner 834b3ecd7c cbfs: Simplify load/map API names, remove type arguments
This patch renames cbfs_boot_map_with_leak() and cbfs_boot_load_file()
to cbfs_map() and cbfs_load() respectively. This is supposed to be the
start of a new, better organized CBFS API where the most common
operations have the most simple and straight-forward names. Less
commonly used variants of these operations (e.g. cbfs_ro_load() or
cbfs_region_load()) can be introduced later. It seems unnecessary to
keep carrying around "boot" in the names of most CBFS APIs if the vast
majority of accesses go to the boot CBFS (instead, more unusual
operations should have longer names that describe how they diverge from
the common ones).

cbfs_map() is paired with a new cbfs_unmap() to allow callers to cleanly
reap mappings when desired. A few new cbfs_unmap() calls are added to
generic code where it makes sense, but it seems unnecessary to introduce
this everywhere in platform or architecture specific code where the boot
medium is known to be memory-mapped anyway. In fact, even for
non-memory-mapped platforms, sometimes leaking a mapping to the CBFS
cache is a much cleaner solution than jumping through hoops to provide
some other storage for some long-lived file object, and it shouldn't be
outright forbidden when it makes sense.

Additionally, remove the type arguments from these function signatures.
The goal is to eventually remove type arguments for lookup from the
whole CBFS API. Filenames already uniquely identify CBFS files. The type
field is just informational, and there should be APIs to allow callers
to check it when desired, but it's not clear what we gain from forcing
this as a parameter into every single CBFS access when the vast majority
of the time it provides no additional value and is just clutter.

Furquan Shaikh 46514c2b87 treewide: Add Kconfig variable MEMLAYOUT_LD_FILE
This change defines a Kconfig variable MEMLAYOUT_LD_FILE which allows
SoC/mainboard to provide a linker file for the platform. x86 already
provides a default memlayout.ld under src/arch/x86. With this new
Kconfig variable, it is possible for the SoC/mainboard code for x86 to
provide a custom linker file as well.

Makefile.inc is updated for all architectures to use this new Kconfig
variable instead of assuming memlayout.ld files under a certain
path. All non-x86 boards used memlayout.ld under mainboard
directory. However, a lot of these boards were simply including the
memlayout from SoC. So, this change also updates these mainboards and
SoCs to define the Kconfig as required.

BUG=b:155322763
TEST=Verified that abuild with --timeless option results in the same
coreboot.rom image for all boards.

Huayang Duan 062646670f soc/mediatek/mt8183: Set CA and DQ vref range to correct value
The CA vref should alway select range[1]. But in fast calibration flow,
we missed the range selection and caused the CA vref to use the range[0] value.

The DQ vref should select correct range that corresponds to current frequency,
that is for 1600Mbps, 2400Mbps to select range[1], for 3200Mbps and 3600Mbps
to select range[0].

Refer to the 'JESD209-4 - Low Power Double Data Rate 4X(LPDDR4X).pdf',
used MR12 to set Vref(CA) levels, used MR14 to set VREF(DQ) levels.
MR12 range[0] values from 15.0% to 44.9%, range[1] values from 32.9% to 62.9%,
MR14 range[0] and range[1] values same as MR12.

Paul Ma d0ded16529 soc/mediatek: dsi: adjust hfp_byte and hbp_byte if too small
If panel has too small hfp or hbp, hfp_byte or hbp_byte may become
very small value or negative value. When very small value or
negative value is used, the panel will be scrolling or distorted.
This patch adjusts their values so that they are greater than
the minimum value and keep total of them unchanged.

DSI transfer HBP or HFP, There are some extra packet. ex. packet
header(4byte) and eof(2byte) and (next)hs packet header(4 byte).
the hfp_byte = HFP * BPP - packet header(4byte) and eof(2byte)
and (next)hs packet header(4 byte). So the min hfp_byte is 2 when
HFP = 4.

This is equivalent to the Linux kernel DSI change in:

switch the ca53 clock source to the intermediate clock.
Second, disable the armpll_ll clock output.
Third, raise armpll_ll frequency and enable the clock output.
The last, switch the ca53 clock source back to armpll_ll and

Julius Werner 00961676fd Revert "soc/mediatek/mt8183: Force retraining memory if requested"
This reverts commit 285975dbba.

Reason for revert: VB2_RECOVERY_TRAIN_AND_REBOOT was never meant to have
any special effect on memory training behavior. It was just supposed to
be a "reboot automatically after reaching kernel verification" recovery
reason. On x86 devices this was used to prime the separate recovery
MRC cache in the factory (make sure it is initialized before shipping).

This isn't used on Kukui anyway, but in order to make sure nobody copies
this code and keep the behavior consistent between platforms, let's
remove it.

Julius Werner 21a4053fde rules.h: Rename ENV_VERSTAGE to ENV_SEPARATE_VERSTAGE
When CONFIG_SEPARATE_VERSTAGE=n, all verstage code gets linked into the
appropriate calling stage (bootblock or romstage). This means that
ENV_VERSTAGE is actually 0, and instead ENV_BOOTBLOCK or ENV_ROMSTAGE
are 1. This keeps tripping up people who are just trying to write a
simple "are we in verstage (i.e. wherever the vboot init logic runs)"
check, e.g. for TPM init functions which may run in "verstage" or
ramstage depending on whether vboot is enabled. Those checks will not
work as intended for CONFIG_SEPARATE_VERSTAGE=n.

This patch renames ENV_VERSTAGE to ENV_SEPARATE_VERSTAGE to try to
clarify that this macro can really only be used to check whether code is
running in a *separate* verstage, and clue people in that they may need
to cover the linked-in verstage case as well.

Bill XIE c79e96b4eb security/vboot: Decouple measured boot from verified boot
Currently, those who want to use measured boot implemented within
vboot should enable verified boot first, along with sections such
as GBB and RW slots defined with manually written fmd files, even
if they do not actually want to verify anything.

As discussed in CB:34977, measured boot should be decoupled from
verified boot and make them two fully independent options. Crypto
routines necessary for measurement could be reused, and TPM and CRTM
init should be done somewhere other than vboot_logic_executed() if
verified boot is not enabled.

In this revision, only TCPA log is initialized during bootblock.
Before TPM gets set up, digests are not measured into tpm immediately,
but cached in TCPA log, and measured into determined PCRs right after
TPM is up.

This change allows those who do not want to use the verified boot
scheme implemented by vboot as well as its requirement of a more
complex partition scheme designed for chromeos to make use of the
measured boot functionality implemented within vboot library to
measure the boot process.

TODO: Measure MRC Cache somewhere, as MRC Cache has never resided in
CBFS any more, so it cannot be covered by tspi_measure_cbfs_hook().

Patrick Georgi 1c6d8a9cf4 soc: Remove copyright notices
They're listed in AUTHORS and often incorrect anyway, for example:
- What's a "Copyright $year-present"?
- Which incarnation of Google (Inc, LLC, ...) is the current
  copyright holder?
- People sometimes have their editor auto-add themselves to files even
  though they only deleted stuff
- Or they let the editor automatically update the copyright year,
  because why not?
- Who is the copyright holder "The coreboot project Authors"?
- Or "Generated Code"?

Sidestep all these issues by simply not putting these notices in
individual files, let's list all copyright holders in AUTHORS instead
and use the git history to deal with the rest.

Huayang Duan 998737df71 soc/mediatek/mt8183: Correct EMI bandwidth threshold for DVFS switch
Because eMCP and discrete DDR devices have different DVFS tables, their
EMI bandwidth thresholds should also be different. When the EMI total
bandwidth reaches the threshold, the system will notify DVFS module to
perform DVFS switch for system performance in low power states.

This patch increases the threshold from 0xa to 0xd for eMCP DDR devices
so that DVFS switch will be less likely to happen.

The register table of EMI_BWCT0 is incorrect in the datasheet. According
to the hardware design, BW_2ND_INT_BW_THR should be in bits [30:24]
instead of [22:16]. However, the logic in DRAM driver is correct,
aligned with the hardware design, so we don't need to correct it.

Jitao Shi f68cc81513 soc/mediatek: dsi: reduce the hbp and hfp for phy timing
The extra data transfer in DSI, namely, lpx, hs_prepare, hs_zero,
hs_exit and the sof/eof of DSI packets, will enlarge the line time,
which causes the real frame on dsi bus to be lower than the one
calculated by video timing. Therefore, hfp_byte is reduced by d_phy to
compensate the increase in time by the extra data transfer. However, if
hfp_byte is not large enough, the hsync period will be increased on DSI
data, leading to display scrolling in firmware screen.

To avoid this situation, this patch changes the DSI Tx driver to reduce
both hfp_byte and hbp_byte, with the amount proportional to hfp and hbp,
respectively. Refer to kernel's change in CL:1915442.

Also rename 'phy_timing' to 'timing' to sync with kernel upstream.

Since the phy timing initialization sequence has been corrected, the m
value adjustment in the analogix driver can be removed.

Julius Werner cefe89ee79 lib/fmap: Add optional pre-RAM cache
This patch adds an optional pre-RAM cache for the FMAP which most
platforms should be able to use, complementing the recently added
post-RAM FMAP cache in CBMEM. vboot systems currently read the FMAP
about half a dozen times from flash in verstage, which will all be
coalesced into a single read with this patch. It will also help
future vboot improvements since when FMAP reads become "free" vboot
doesn't need to keep track of so much information separately.

In order to make sure we have a single, well-defined point where the new
cache is first initialized, eliminate the build-time hardcoding of the
CBFS section offsets, so that all CBFS accesses explicitly read the
FMAP.

Add FMAP_CACHEs to all platforms that can afford it (other than the
RISC-V things where I have no idea how they work), trying to take the
space from things that look like they were oversized anyway (pre-RAM
consoles and CBFS caches).

Yu-Ping Wu 02d9071a0b soc/mediatek/mt8183: Disable DRAM DVFS in recovery mode
Currently full calibration with DVFS (which implies tripling memory
training time for multiple frequencies) will be run in recovery mode,
which takes up to 30 seconds with serial console enabled.

However, in recovery mode the system should be running only the recovery
programs with minimal services. DVFS should be not needed.

In order to improve stability and system boot time, we want to disable
DVFS training in recovery mode.

Hung-Te Lin 285975dbba soc/mediatek/mt8183: Force retraining memory if requested
To allow retraining memory without hotkey (for example in manufacturing
process), we want to enforce re-training when the recovery reason is set
to VB2_RECOVERY_TRAIN_AND_REBOOT (which can be done by running
 "crossystem recovery_request=0xc4").

The special reason was created for X86 MRC cache, for ensuring RO
calibration data is filled (the underlying implementation was in vboot,
not coreboot); and on MT8183 we have only RW calibration, but it seems
totally fine to extend that for RW.

If DRAM calibration fails or mem test fails using the cached calibration
results stored in flash, rerun DRAM full calibration. If partial
calibration fails or the mem test following it fails, hang forever.

Partial calibration acts as a fallback approach in case of full
calibration failure. Therefore, if it fails, there would be no other
ways to initialize DRAM. Instead of falling into reboot loop and
draining out of battery, it is better to just hang so that the end user
may notice that and send to RMA.

Julius Werner b3f24b4884 arm64: Uprev Arm TF and adjust to BL31 parameter changes
This patch uprevs the Arm Trusted Firmware submodule to the new upstream
master (commit 42cdeb930).

Arm Trusted Firmware unified a bunch of stuff related to BL31 handoff
parameters across platforms which involved changing a few names around.
This patch syncs coreboot back up with that. They also made header
changes that now allow us to directly include all the headers we need
(in a safer and cleaner way than before), so we can get rid of some
structure definitions that were duplicated. Since the version of entry
point info parameters we have been using has been deprecated in Trusted
Firmware, this patch switches to the new version 2 parameter format.

NOTE: This may or may not stop Cavium from booting with the current
pinned Trusted Firmware blob. Cavium maintainers are still evaluating
whether to fix that later or drop the platform entirely.

Tested on GOOGLE_KEVIN (rk3399).
