ac55dadb1c fsl: Secure Boot: Enable IE (Key extention) Feature
For validating images from uboot (Such as Kernel Image), either keys
from SoC fuses can be used or keys from a verified table of public
keys can be used. The latter feature is called IE Key Extension
Feature.

For Layerscape Chasis 3 based platforms, IE table is validated by
Bootrom and address of this table is written in scratch registers 13
and 14 via PBI commands.

Following are the steps describing usage of this feature:

1) Verify IE Table in ISBC phase using keys stored in fuses.
2) Install IE table. (To be used across verification of multiple
   images stored in a static global structure.)
3) Use keys from IE table, to verify further images.

This patch allows using i2c commands (e.g. "i2c probe", "i2c md", etc)

b52a3fa08b i2c: ti: Update method to calculate psc, sscl and ssch I2C parameters
This patch updates the way in which psc, sscl and ssch I2C parameters are
calculated to be in sync with v4.9 Linux kernel
SHA1: 69973b830859bc6529a7a0468ba0d80ee5117826
in the ./drivers/i2c/busses/i2c-omap.c

The previous method was causing several issues:
- The internal I2C frequency (after prescaler) was far above recommended
one (7 - 12 MHz [*]) - the current approach brings better noise suppression
(as stated in Linux commit: SHA1: 84bf2c868f3ca996e5bb)

- The values calculated (psc, sscl and ssch) were far from optimal, which
caused on the test platform (AM57xx) the I2C0 SCL signal low time (Fast
Mode) of ~1.0us (the standard requires > 1.3 us).

0f5b461b9b i2c: lpc32xx: Force consistent bus numbering
Normally, this would probably be done by adding devicetree aliases
to the main dtsi file for the lpc32xx and using bus->req_seq instead.

Since we want to have consistent i2c numbering, we cannot force the
bus->req_seq because. If for instance we have 3 buses numbered
from 0 to 2 with i2c0 enabled, i2c1 disabled and i2c2 enabled;
i2c2 can be selected using 'i2c dev 1' and 'i2c dev 2' commands
because a bus can be probed using req_seq or seq interchangeably.

0f4b2ba176 tpm: Add function to load keys via their parent's SHA1 hash
If we want to load a key into a TPM, we need to know the designated parent
key's handle, so that the TPM is able to insert the key at the correct place in
the key hierarchy.

However, if we want to load a key whose designated parent key we also
previously loaded ourselves, we first need to memorize this parent key's handle
(since the handles for the key are chosen at random when they are inserted into
the TPM). If we are, however, unable to do so, for example if the parent key is
loaded into the TPM during production, and its child key during the actual
boot, we must find a different mechanism to identify the parent key.

To solve this problem, we add a function that allows U-Boot to load a key into
the TPM using their designated parent key's SHA1 hash, and the corresponding
auth data.

db40c1aa1c drivers/net/phy: add fixed-phy / fixed-link support
This patch adds support for having a "fixed-link" to some other MAC
(like some embedded switch-device).

For this purpose we introduce a new phy-driver, called "Fixed PHY".

Fixed PHY works only with CONFIG_DM_ETH enabled, since the fixed-link is
described with a subnode below ethernet interface.

Most ethernet drivers (unfortunately not all are following same scheme
for searching/attaching phys) are calling "phy_connect(...)" for getting
a phy-device.
At this point we link in, we search here for a subnode called "fixed-
link", once found we start phy_device_create(...) with the special phy-
id PHY_FIXED_ID (0xa5a55a5a).

During init the "Fixed PHY" driver has registered with this id and now
gets probed, during probe we get all the details about fixed-link out of
dts, later on the phy reports this values.

f8e57c650d fdt_support: Fixup 'ethernet' aliases not ending in digits
The Raspberry Pi device tree files since Linux v4.9 have a "ethernet"
alias pointing to the on-board Ethernet device node. However,
U-Boot's fdt_fixup_ethernet() only looks at ethernet aliases ending
in digits.

As the spec doesn't mandate that aliases must end in numbers and there
have been much older uses of an "ethernet" aliases in the wild
(according to Tom Rini), change the code to accept "ethernet" as well.

Without this Linux isn't told of the MAC address provided by the
RPI firmware and the ethernet interface is always assigned a random MAC
address.

0c77092e81 arc: dts: separate single axs10x.dts file
We want to use the same device tree blobs in both Linux and U-Boot for
ARC boards.

Earlier device tree sources in U-Boot were very simplified and hadn't been
updated for quite a long period of time.

So this commit is the first step on the road to unified device tree blobs.

First of all we re-organize device tree sources for AXS10X boards.
As AXS101 and AXS103 boards consist of AXS10X motherboard and AXC001 and
AXC003 cpu tiles respectively we add corresponding device tree source
files: axs10x_mb.dtsi for motherboard, axc001.dtsi and axc003.dtsi for
cpu tiles and axs101.dts and axs103.dts to represent actual boards.

Also we delete axs10x.dts as it is no longer used.

One more important change - we add timer device to ARC skeleton device
tree sources as both ARC700 and ARCHS cores contain such timer.
We add core_clk nodes to abilis_tb100, nsim, axc001 and axc003 device tree
sources as it is referenced via phandle from timer node in common
skeleton.dtsi file.

2a792753d6 dm: Add callback to modify the device tree
Certain boards come in different variations by way of utilizing daughter
boards, for example. These boards might contain additional chips, which
are added to the main board's busses, e.g. I2C.

The device tree support for such boards would either, quite naturally,
employ the overlay mechanism to add such chips to the tree, or would use
one large default device tree, and delete the devices that are actually
not present.

Regardless of approach, even on the U-Boot level, a modification of the
device tree is a prerequisite to have such modular families of boards
supported properly.

Therefore, we add an option to make the U-Boot device tree (the actual
copy later used by the driver model) writeable, and add a callback
method that allows boards to modify the device tree at an early stage,
at which, hopefully, also the application of device tree overlays will
be possible.

1ec2a80b10 arm: mvebu: theadorable: Add 'pcie' test command
This board specific command tests for the presence of a specified PCIe
device (via vendor-ID and device-ID). If the device is not detected,
this will get printed. If the device is detected, the board will get
resetted so that an easy loop test can be done. The board will reboot
until the PCIe device is not detected.

1304f4bb8e arm: mvebu: theadorable: Add board-specific PEX detection pulse width
Define a board-specific detection pulse-width array for the SerDes PCIe
interfaces. If not defined in the board code, the default of currently 2
is used. Values from 0...3 are possible (2 bits).

In this case of the theadorable board, PEX interface 0 needs a value
of 0 for the detection pulse width so that the PCIe device (Atheros
WLAN PCIe device) is consistantly detected.

2399e40120 arm: mvebu: AXP: Add possiblity to configure PEX detection pulse width
Tests have shown that on some boards the default width of the
configuration pulse for the PEX link detection might lead to
non-established PCIe links (link down). Especially under certain
conditions (higher temperature) and with specific PCIe devices
(in the case on the theadorable board its a Atheros PCIe WLAN
device). To enable a board-specific detection pulse width this weak
array "serdes_pex_pulse_width[4]" is introduced which can be
overwritten if needed by a board-specific version. If the board
code does not provide a non-weak version of this variable, the
default value will be used. So nothing is changed from the
current setup on the supported board.

Many thanks to Adam from Marvell for all his insights here and
his suggestion about testing with a changed detection pulse width.
