0f7e086229 drivers/intel/usb4/retimer: Update code to assign correct port number
Since TBT controller can have maximum 2 ports per controller, our
code will loop over DFP structure twice and determine port number.

Retimer driver used to assign port number as below:
1. Check if power GPIO is assigned for particular DFP entry or not
2. If entry is there, assign loop count as port number

Since loop count is 2, retimer will never assign port number = 2
even if it's present. In case of more than 1 controller, port number
assigned will still be 0 or 1 even though actual port index might
be 2 or 3. This will create an issue where even if you do transaction
on device on controller 2 (port index 2 or 3), EC will route it on
port 0 or 1 due to incorrect port index.

Update the driver flow as per below to handle this scenario:
1. Check if power GPIO is assigned for particular DFP entry or not
2. Get USB port number from config since it's stored in usb port
   information under devicetree
3. Pass the port number to ACPI SSDT and EC code

Above changes will ensure that we're assigning correct port
number as per calculation and EC will use correct port index.

BUG=b:189476816
BRANCH=None
TEST=Checked that retimer firmware update works on both ports and update
happens on correct port index.

a6b60ebedb drivers/intel/gma: Move extended VBT just below opregion
Currently the flow for opregion init is as below:
1. Allocate memory for opregion first (cbmem_add(opregion))
2. Check if VBT size > 6 KiB (this requires extended VBT support)
3. In case of extended VBT requirement, we allocate another chunk
   of memory which is equal to size of VBT (cbmem_add(extended_vbt))
4. Pass physical address pointer to OS via RVDA

We can optimize the above flow to allocate single chunk of memory by
checking VBT size in earlier step. The new optimized flow for opregion
init is as below:
1. Check if VBT size > 6 KiB (this requires extended VBT support)
2. In case of extended VBT requirement, total memory to be allocated
   is calculated as sizeof(opregion) + sizeof (extended_vbt)
   In case where VBT size is < 6 KiB, total memory requirement would
   be equal to sizeof(opregion)
3. Based on above calculation, allocate single chunk of memory based on
   total size.

This will also be helpful for the case of virtualization where guest
users don't have access to physical address and when it needs relative
address of VBT compared to absolute address.

In case of opregion 2.1 spec, we need to pass relative address of
VBT from opregion base in RVDA. This optimization will help in meeting
this requirement since relative address of extended VBT is easy to get.
This change will ensure that it meets opregion specification
requirement and will be compatible with future versions as well.

BUG=b:190019970
BRANCH=None
TEST=check the address of extended VBT region and address is coming
correctly.

8c9a89de99 arch/x86/ioapic: Drop irq_on_fsb as a configurable item
APIC Serial Bus pins were removed with ICH5 already, so a choice
'irq_on_fsb = 0' would not take effect. The related register BOOT_CONFIG
0x3 is also not documented since ICH5.

For emulation/qemu-q35 with ICH9 the choice INTERRUPT_ON_APIC_BUS was
wrong and ignored as BOOT_CONFIG register emulation was never implemented.

For ICH4 and earlier, the choice to use FSB can be made based on the
installed CPU model but this is now just hardwired to match P4 CPUs of
aopen/dxplplusu.

For sb/intel/i82371eb register BOOT_CONFIG 0x3 is also not defined
and the only possible operation mode there is APIC Serial Bus, which
requires no configuration.

146508d749 drivers/intel/fsp2_0: Add timestamps for loading FSPM & FSPS
The loads of the FSPM and FSPS binaries are not insignificant amounts of
time, and without these timestamps, it's not clear what's going on in

6b4b4a8349 drivers/pcie/rtd3/device: Add PCIe RTD3 driver
This driver was inspired from soc/intel/common/block/pci/rtd3. I decided
to copy and modify it because the Intel driver has a lot of Intel
specific code.

This driver has been stripped down to only provide a power resource and
set the StorageD3Enable property. This driver is SoC agnostic and does
not handle suspending the actual PCIe root port. That should be
implemented by an SoC specific driver.

This is required for Guybrush to suspend/resume properly because the
NVMe power is tied to the S0 power rails, so the kernel needs to place
the device into D3.

1e02ad3f5a drivers/i2c/designware: Report I2C timings for additional bus speeds
Since the OS provides its own driver for the I2C controller it can
choose to use a bus speed other than the one used at coreboot runtime.
In this case it would be good to provide a way how the needed bus
timings are communicated to the OS, since these are very board-specific
and there is no way that the OS can know them other than read the
appropriate ACPI reported timings.
This patch adds some code to report additional bus speed timings if

686018988c drivers/pc80/mc146818rtc: Check date and time for sanity
There are cases where the RTC_VRT bit in register D stays set after a
power failure while the real date and time registers can contain rubbish
values (can happen when RTC is not buffered). If we do not detect this
invalid date and/or time here and keep it, Linux will use these bad
values for the initial timekeeper init. This in turn can lead to dates
before 1970 in user land which can break a lot assumptions.

To fix this, check date and time sanity when the RTC is initialized and
reset the values if needed.

964948d97f drivers/i2c/rx6110sa: Add a Kconfig switch to disable ACPI support
In commit b64db833d6 a basic ACPI support was added to the driver.
With this support an SSDT-entry is created for this RTC and it is now
visible to the OS via ACPI. In Linux the PNP-devices, which are
reported over ACPI, are scanned rather early and if the entry is found,
the device is claimed even if there is no driver available yet.
In this case, when the native RTC-driver without ACPI-support is loaded
and tries to register this device, the RTC is already blocked by the
PNP-drivers and cannot be used anymore. This leads to a non-usable RTC
on kernels where the needed ACPI-extension is not yet merged into the
RTC driver.

This patch provides a way to disable the ACPI-support for the RTC if
needed.

e0dbeee40f drivers/sn65dsi86: Switch EDID reading to use "indirect mode"
The SN65DSI86 eDP bridge supports two ways to read the EDID: for now
we've been using "direct mode", which works by basically making the
bridge I2C device listen to another chip address besides its own and
proxy all requests received there directly to the eDP AUX channel. The
great part about that mode is that it is super easy and hassle-free to
use. The not so great part about it is that it doesn't work: for EDID
extensions, the last byte (which happens to contain the checksum) is
somehow always read as zero. We presume this is a hardware bug in the
bridge part.

The other, much more annoying way is "indirect mode", where each byte
transmitted over the AUX channel has to be manually set up in the I2C
registers of the bridge, just like we're already doing with DPCD
transactions. Thankfully, we can reuse most of the DPCD code for this so
it's not a lot of extra code. It's a bit slower but not as much as you'd
expect (26ms instead of 18ms on my board), and the difference is not
very relevant compared to common total times for display init.

Also, some of the (previously unused) enum definitions for the AUX_CMD
mode field of the bridge had just been plain wrong for some reason, and
needed to be fixed to make this work.
