2a9059aef5 arm: a37xx: pci: Ensure that root port is always on root zero bus
Writing to the PCI_PRIMARY_BUS register of the root port should not change
bus number on which is root port present.

This PCI_PRIMARY_BUS register is used only for correct configuration of
legacy PCI stuff, like forwarding of PCI special cycles between buses.

Aardvark HW does not support PCI special cycles, so it does not have HW
register for PCI_PRIMARY_BUS and therefore it does not matter what is
stored in this register.

So fix this issue and do not use PCI_PRIMARY_BUS register in pci-aardvark.c
driver for moving root bus of the root port.

After this change there is no reason for storing bus number (zero) into
first_busno variable, so remove this variable.

cf2a589a89 arm: a37xx: pci: Cleanup macro names
Remove "PCI_" prefix from all macros which are aardvark specific to not
conflict with macros defined in global include file pci.h. Instead add
"ADVK_" prefix for them so it is visible that they are aardvark specific.

After "ADVK_" prefix append keyword which describes register group, so it
would be clear to which register each macro value belongs.

Rename some macros for consistency with other macros.

819a43c90a arm: a37xx: pci: Use standard register macros from pci.h
PCI config space of the aardvark PCIe Root Port is available only in
internal aardvark memory space starting at offset 0x0. PCI Express
registers (PCI_EXP_*) start at offset 0xc0. And Advanced Error Reporting
registers (PCI_ERR_*) start at offset 0x100.

Replace custom aardvark register macros by standard PCI macros from
include/pci.h file with fixed offset.

Some DEVCTL and AER macros are not defined in include/pci.h file, so define
them in the same way as in linux uapi header file pci_regs.h.

54cebe8a3a efi_loader: fix dual signed image certification
The EFI spec allows for images to carry multiple signatures. Currently
we don't adhere to the verification process for such images.

The spec says:
"Multiple signatures are allowed to exist in the binary's certificate
table (as per PE/COFF Section "Attribute Certificate Table"). Only one
hash or signature is required to be present in db in order to pass
validation, so long as neither the SHA-256 hash of the binary nor any
present signature is reflected in dbx."

With our current implementation signing the image with two certificates
and inserting both of them in db and one of them dbx doesn't always reject
the image.  The rejection depends on the order that the image was signed
and the order the certificates are read (and checked) in db.

While at it move the sha256 hash verification outside the signature
checking loop, since it only needs to run once per image and get simplify
the logic for authenticating an unsigned imahe using sha256 hashes.

d9612f4426 tools: mkeficapsule: allow for specifying GUID explicitly
The existing options, "--fit" and "--raw," are only used to put a proper
GUID in a capsule header, where GUID identifies a particular FMP (Firmware
Management Protocol) driver which then would handle the firmware binary in
a capsule. In fact, mkeficapsule does the exact same job in creating
a capsule file whatever the firmware binary type is.

To prepare for the future extension, the command syntax will be a bit
modified to allow users to specify arbitrary GUID for their own FMP driver.

   [--fit <image> | --raw <image>] <capsule file>

16abff246b tools: mkeficapsule: add firmware image signing
With this enhancement, mkeficapsule will be able to sign a capsule
file when it is created. A signature added will be used later
in the verification at FMP's SetImage() call.

To do that, we need specify additional command parameters:
  -monotonic-cout <count> : monotonic count
  -private-key <private key file> : private key file
  -certificate <certificate file> : certificate file
Only when all of those parameters are given, a signature will be added
to a capsule file.

Users are expected to maintain and increment the monotonic count at
every time of the update for each firmware image.

9ebfc6ba5b CI: enforce packages upgrade for Msys2 on Windows
We need to install libgnutls-devel package to build the host tool,
mkeficapsule, and as of now, there seems to be a depencency conflict
in the current msys2 installer;

   :: installing libp11-kit (0.24.1-1) breaks dependency \
	'libp11-kit=0.23.22' required by p11-kit

To resolve this conflict, however, the initial "pacman -Syyuu" in
'tools_only_windows' job is not enough. Another "pacman -Su" will
enforce all the out-of-date packages being upgraded.
(Probably the first "-Syyuu" can be changed to "-Syu".)

07c79dd5fd fw_env: simplify logic & code paths in the fw_env_open()
Environment variables can be stored in two formats:
1. Single entry with header containing CRC32
2. Two entries with extra flags field in each entry header

For that reason fw_env_open() has two main code paths and there are
pointers for CRC32/flags/data.

Previous implementation was a bit hard to follow:
1. It was checking for used format twice (in reversed order each time)
2. It was setting "environment" global struct fields to some temporary
   values that required extra comments explaining it

This change simplifies that code:
1. It introduces two clear code paths
2. It sets "environment" global struct fields values only once it really
   knows them

To be fair there are *two* crc32() calls now and an extra pointer
variable but that should be cheap enough and worth it.

Behaviour of flash_io() was a bit unintuitive as it was writing to a

The ci_req->hw_buf can be NULL, test whether it is and if so,
avoid accessing it. Else, the system may crash.

96991e652f console: usb: kbd: Limit poll frequency to improve performance
Using the XHCI driver, the function `usb_kbd_poll_for_event` takes
30-40ms to run. The exact time is dependent on the polling interval the
keyboard requests in its descriptor, and likely cannot be significantly
reduced without major rework to the XHCI driver.

The U-Boot EFI console service sets a timer to poll the keyboard every 5
microseconds, and this timer is checked every time a block is read off
disk. The net effect is that, on my system, loading a ~40MiB kernel and
initrd takes about 62 seconds with a slower keyboard and 53 seconds
with a faster one, with the vast majority of the time spent polling the
keyboard.

To solve this problem, this patch adds a 20ms delay between consecutive
calls to `usb_kbd_poll_for_event`. This is sufficient to reduce the
total loading time to under half a second for both keyboards, and does
not impact the perceived keystroke latency.

078dfef931 usb: ehci-mx6: Enable OTG detection on imx8mm and imx8mn
The imx8mm and imx8mn appear compatible with imx7d-usb
flags in the OTG driver.  If the dr_mode is defined as
host or peripheral, the device appears to operate correctly,
however the auto host/peripheral detection results in an error.

The solution isn't just adding checks for imx8mm and imx8mn to
the check for imx7, because the USB clock needs to be running
to read from the USBNC_PHY_STATUS_OFFSET register or it will hang.

Marek requested that I not enable the clocks in ehci_usb_of_to_plat,
so I modified that function to return an unknown state if the
device tree does not explicitly state whether it is a host
or a peripheral.

When the driver probes, it looks to see if it's in the unknown
state, and only then will it read the register to auto-detect.

ad41ed1208 arm:dts:k3-am64-sk: EMIF tool update to 0.8.0 with 1333MTs for lpddr4
EMIF tool for AM64 SK is now updated to 0.8.0 that includes
* disabled Write DQ training
* improve CA ODT to 60 ohms

The lpddr4 enabled with periodic WDQ training is causing periodic 26us
stall. This makes the SoC stall without doing anything which leads to
R5 interrupt latency in TCM memory. Due to this periodic training there
are some outstanding CPU transactions waiting for the lpddr4 to complete.

Hence, disable the periodic write DQ training during the
non-initialization stage of lpddr4 which results in an approximate 1us
stall. Also, update the lpddr4 config to improve CA ODT by 60 ohms

The rationales are as follows:
- PI_WDQLVL_EN: 2 Bits register field to support write DQ leveling,
  disable bit 1 that supports Write DQ during non-initialization to
  avoid ~26us stall during code execution.

- MR11_DATA_F1/F2_x register fields value changed to 0x66 that changes
  the CA ODT from 48ohm to 60ohm to improve the eye margin on CA bus by
  increasing the signal swing.
