ARM: tegra: fix ULPI PHY on Ventana and Seaboard

Commit ce02a71c2374 "tegra: dts: Sync tegra20 device tree files with

that U-Boot code could handle this. In practice, various code is missing,
and various configuration options are not enabled, which causes U-Boot to
hang when attempting to initialize this USB port. This patch enables ULPI
PHY support on Ventana, and adds the required pinmux setup for the port to
operate. Note that Ventana is so similar to Seaboard that this change is
made in the Seaboard board file, which is shared with Ventana.

Seaboard also has the ULPI USB port wired up in hardware, although to an
internal port that often doesn't have anything attached to it. However,
the DT nodes for the USB controller and PHY had different status property
values, so the port was not initialized by U-Boot. Fix this inconsistency,
and enable the ULPI port, just like in the Linux kernel DT. This likewise
requires enabling ULPI support in the Seaboard defconfig.

ARM: tegra: fix USB controller aliases

Some boards have a different set of USB controllers enabled in DT than
the set referenced by /alias entries. This patch fixes that. For
example, this avoids the following message while booting on Ventana,
which is caused by the fact that the USB0 controller had no alias, and
defaulted to wanting a sequence number of 0, which was later explicitly
requested by the alias for USB controller 2.

USB2:   Device 'usb@c5008000': seq 0 is in use by 'usb@c5000000'

This didn't affect USB operation in any way though.

Related, there's no need for the USB controller aliases to have an order
that's different from the HW order, so re-order any aliases to match the
HW ordering. This has the benefit that since USB controller 0 is the only
one that supports device-mode in HW, and U-Boot only supports enabling
device move on controller 0, there's now good synergy in the ordering! For
Tegra20, that's not relevant at present since USB device mode doesn't work
correctly on that SoC, but it will save some head-scratching later.

This patch doesn't fix the colibri_t20 board, even though it has the same
issue, since Marcel already sent a patch for that.

ARM: tegra: add APIs the clock uclass driver will need

A future patch will implement a clock uclass driver for Tegra. That driver
will call into Tegra's existing clock code to simplify the transition;
this avoids tieing the clock uclass patches into significant refactoring
of the existing custom clock API implementation.

Some of the Tegra clock APIs that manipulate peripheral clocks require
both the peripheral clock ID and parent clock ID to be passed in together.
However, the clock uclass API does not require any such "parent"
parameter, so the clock driver must determine this information itself.
This patch implements new Tegra- specific clock API
clock_get_periph_parent() for this purpose.

The new API is implemented in the core Tegra clock code rather than SoC-
specific clock code. The implementation uses various SoC-/clock-specific
data. That data is only available in SoC-specific clock code.
Consequently, two new internal APIs are added that enable the core clock
code to retrieve this information from the SoC-specific clock code. Due to
the structure of the Tegra clock code, this leads to some unfortunate code
duplication. However, this situation predates this patch.

Ideally, future work will de-duplicate the Tegra clock code, and migrate
it into drivers/clk/tegra. However, such refactoring is kept separate from
this series.

ARM: tegra: add peripheral clock init table

Currently, Tegra peripheral drivers control two aspects of their HW module
clock(s):

1) The clock enable/rate for the peripheral clock itself.

2) The system-level clock tree setup, i.e. the clock parent.

Aspect 1 is reasonable, but aspect 2 is a system-level decision, not
something that an individual peripheral driver should in general know
about or influence. Such system-level knowledge ties the driver to a
specific SoC implementation, even when they use generic APIs for clock
manipulation, since they must have SoC-specific knowledge such as parent
clock IDs. Limited exceptions exist, such as where peripheral HW is
expected to dynamically switch between clock sources at run-time, such
as CPU clock scaling or display clock conflict management in a multi-head
scenario.

This patch enhances the Tegra core code to perform system-level clock
tree setup, in a similar fashion to the Linux kernel Tegra clock driver.
This will allow future patches to simplify peripheral drivers by removing
the clock parent setup logic.

This change is required prior to converting peripheral drivers to use the
standard clock APIs, since:

1) The clock uclass doesn't currently support a set_parent() operation.
Adding one is possible, but not necessary at the moment.

2) The clock APIs retrieve all clock IDs from device tree, and the DT
bindings for almost all peripherals only includes information about the
relevant peripheral clocks, and not any potential parent clocks.

Nothing needs access to this type except the MMC driver itself. Move the
definition into the driver C file.

Make sure all Tegra MMC functions are named tegra_mmc_*. Even though
they're all static, it's useful to have good naming so that symbol tables

arm64: mvebu: Add basic support for the Marvell Armada 7K/8K SoC

Compared to the Armada 3700, the Armada 7K and 8K are much more on the
high-end side: they use a dual Cortex-A72 or a quad Cortex-A72, as
opposed to the Cortex-A53 for the Armada 3700.

The Armada 7K and 8K also use a fairly unique architecture, internally
they are composed of several components:

- One AP (Application Processor), which contains the processor itself
  and a few core hardware blocks. The AP used in the Armada 7K and 8K
  is called AP806, and is available in two configurations:
  dual Cortex-A72 and quad Cortex-A72.
- One or two CP (Communication Processor), which contain most of the I/O
  interfaces (SATA, PCIe, Ethernet, etc.). The 7K family chips have one
  CP, while the 8K family chips integrate two CPs, providing two times
  the number of I/O interfaces available in the CP.
  The CP used in the 7K and 8K is called CP110.

All in all, this gives the following combinations:

- Armada 7020, which is a dual Cortex-A72 with one CP
- Armada 7040, which is a quad Cortex-A72 with one CP
- Armada 8020, which is a dual Cortex-A72 with two CPs
- Armada 8040, which is a quad Cortex-A72 with two CPs

This patch adds basic support for this ARMv8 based SoC into U-Boot.

starting with the Marvell DB-88F7040 development board.

Not like A380, in Armada3700, there are two layers of decode windows for GBE:
First layer is:  GbE Address window that resides inside the GBE unit,
Second layer is: Fabric address window which is located in the NIC400

To simplify the address decode configuration for Armada3700, we bypass the

always have, setting a minimum size of 32MiB for malloc is reasonable.
However, in the SPL case not only do we not need that much we start
running into overlap problems and then will fail to boot.  Since we

reset: add no-op stubs for optional reset control

My motivation for this patch is to make reset control handling
optional for generic drivers.

I want to add reset control to drivers/usb/host/ehci-generic.c,
but it is used by several platforms, some will implement a reset
