6dca554f23 ARM: tegra: fix ULPI PHY on Ventana and Seaboard
Commit ce02a71c23 "tegra: dts: Sync tegra20 device tree files with
Linux" enabled the ULPI USB port on Ventana, but made no attempt to ensure
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.

002ddbffb6 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.

2f6a7e8ce5 ARM: tegra: fix USB ULPI PHY reset signal inversion confusion
USB ULPI PHY reset signals are typically active low. Consequently, they
should be marked as GPIO_ACTIVE_LOW in device tree, and indeed they are in
the Linux kernel DTs, and in DT properties that U-Boot doesn't yet use.
However, in DT properties that U-Boot does use, the value has been set to
0 (== GPIO_ACTIVE_HIGH) to work around a bug in U-Boot.

This change fixes the DT to correctly represent the HW, and fixes the
Tegra USB driver to cope with the fact that dm_gpio_set_value() internally
handles any inversions implied by the DT value GPIO_ACTIVE_LOW.

7468676684 ARM: tegra: fix clock_get_periph_rate() for UART clocks
Make clock_get_periph_rate() return the correct value for UART clocks.

This change needs to be applied before the patches that enable CONFIG_CLK
for Tegra SoCs before Tegra186, since enabling that option causes
ns16550_serial_ofdata_to_platdata() to rely on clk_get_rate() for UART
clocks, and clk_get_rate() eventually calls clock_get_periph_rate().

This change is a rather horrible hack, as explained in the comment added
to the clock driver. I've tried fixing this correctly for all clocks as
described in that comment, but there's too much fallout elsewhere. I
believe the clock driver has a number of bugs which all cancel each-other
out, and unravelling that chain is too complex at present. This change is
the smallest change that fixes clock_get_periph_rate() for UART clocks
while guaranteeing no change in behaviour for any other clock, which
avoids other regressions.

d0ad8a5cbf 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.

6dbcc962e4 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.

ee562dc34e ARM: tegra: pull Tegra210 SoC DT from Linux v4.7
The primary benefit of this change is that it adds all missing clocks and
resets properties to peripherals. This will allow peripheral drivers to
migrate to the standard clock and reset APIs in the future.

Main changes:
* Brought in the correct Tegra210 CAR binding; the old file in U-Boot
  appears to be a renamed version of the Tegra124 bindings rather than
  the real Tegra210 version.
* Conversion of SPI and UART nodes to standard DMA bindings. U-Boot
  doesn't use DMA so isn't affected.
* Split of EHCI and USB PHY nodes. The EHCI nodes continue to contain all
  information required by U-Boot, so U-Boot is not affected.
* Conversion of many magic numbers to named defines.
* Addition of many nodes not used by U-Boot, including separation of the
  Tegra LIC (Legacy IRQ controller) and GIC.
* Node sort order fixes.

Remaining deltas relative to the Linux DT:
* U-Boot has enabled PCIe for Tegra210, but the kernel hasn't yet.
* The GPIO node compatible value in the kernel explicitly includes
  Tegra124 values whereas U-Boot does not. I'll send a kernel patch to
  correct this.

3b8c1b3b22 ARM: tegra: pull Tegra124 SoC DT from Linux v4.7
The primary benefit of this change is that it adds all missing clocks and
resets properties to peripherals. This will allow peripheral drivers to
migrate to the standard clock and reset APIs in the future.

Main changes:
* USB phy_type property is aligned with the kernel, so board files are
  updated so the final DT content doesn't change. I'm not convinved that
  Nyan uses HSIC phy_type. However, I'd rather this change be a no-op,
  and any DT bug-fixes be separate.
* Sync misc changes from the kernel: missing DT content, minor compatible
  value fixes, typos.

Remaining deltas relative to the Linux DT:
* U-Boot uses #address-cells/#size-cells of 1 whereas the kernel uses 2.
  I believe U-Boot's DT parsing currently assumes that these values match
  the physical address size, so I didn't synchronize this part of the DT.
* U-Boot uses the original XUSB PHY DT binding, wherease the kernel DT
  has moved to a newer version. Thus, XUSB client nodes include properties
  names phys and phy-names that do not appear in the kernel, and don't
  include pad definitions in the padctl node.

migrate to the standard clock and reset APIs in the future.

Main changes:

* Changed the phy_type value for the second USB port. This required board
  DTs to be updated to keep the same configuration.
* Boards need to define the clk32k_in clock that feeds the Tegra PMC.
* Addition of tegra30-mc.h since tegra30.dtsi now includes it.
* Conversion of many magic numbers to named defines.
* Addition of many nodes not used by U-Boot.
* Node sort order fixes.

Remaining deltas relative to the Linux DT:

f53c4e4bbd mmc: tegra: priv struct and naming cleanup
struct mmc_host is a Tegra-specific structure, but the name implies it's
something defined by core MMC code, which is confusing. Rename it to
struct tegra_mmc_priv to make its purpose more obvious. The new name is
also more appropriate for a DM driver private data structure, which will
be relevant later in this series.

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
are easy to interpret. A few functions aren't renamed by this patch since
they'll be deleted by a subsequent patch in this series.

21b29fc64e 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.
Future patches will integrate other device drivers and board support,
starting with the Marvell DB-88F7040 development board.

31d36f748c MIPS: Hang if run on a secondary CPU
Some systems are configured such that multiple CPUs begin running from
their reset vector following a system reset. If this occurs then U-Boot
will be run on multiple CPUs simultaneously, which causes all sorts of
issues as the multiple instances of U-Boot clobber each other.

Prevent this from happening by simply hanging with an infinite loop if
we run on a CPU whose ID, as determined by GlobalNumber or EBase.CPUNum
as appropriate, is non-zero.

d263cda5ae MIPS: Fix cache maintenance in relocate_code & simplify
The relocate_code function was handling cache maintenance incorrectly.
It copied U-Boot to its new location, flushed the caches & then
proceeded to apply relocations & jump to the new code without flushing
the caches again. This is problematic as the instruction cache could
potentially have already fetched instructions that hadn't had relocs
applied.

Rework this to perform the flush_cache call using the code in the
original copy of U-Boot, after having applied relocations to the new
copy of U-Boot. The new U-Boot can then be jumped to safely once that
cache flush has been performed.

As part of this, since the old U-Boot is used up until after that cache
flush, complexity around loading values from the GOT using a jump & link
instruction & loads from a table is removed. Instead we can simply load
the needed values with PTR_LA fromt the original GOT.

instruction cache as early as possible. Otherwise we initialise the L2
first such that the L1s have no opportunity to generate access to the
uninitialised L2.

f8981277f5 MIPS: If we don't need DDR for cache init, init cache first
On systems where cache initialisation doesn't require zeroed memory (ie.
systems where CONFIG_SYS_MIPS_CACHE_INIT_RAM_LOAD is not defined)
perform cache initialisation prior to lowlevel_init & DDR
initialisation. This allows for DDR initialisation code to run cached &
thus significantly faster.

4f9226b403 MIPS: Preserve Config implementation-defined bits
The coprocessor 0 Config register includes 9 implementation defined
bits, which in some processors do things like enable write combining or
other functionality. We ought not to wipe them to 0 during boot. Rather
than doing so, preserve their value & only clear the bits standardised
by the MIPS architecture.

33b5c9b209 MIPS: Enable use of the instruction cache earlier
Enable use of the instruction cache immediately after it has been
initialised. This will only take effect if U-Boot was linked to run from
kseg0 rather than kseg1, but when this is the case the data cache
initialisation code will run cached & thus significantly faster.

8cb4817d0f MIPS: Probe cache line sizes once during boot
Rather than probing the cache line sizes on every call of any cache
maintenance function, probe them once during boot & store the values in
the global data structure for later use. This will reduce the overhead
of the cache maintenance functions, which isn't a big deal yet but
becomes more important once L2 caches which may expose their properties
via coprocessor 2 or the CM are supported.

adf32adb70 PowerPC: Update MIP405/MIP405T to use Kconfig better
Convert CONFIG_MIP405T from SYS_EXTRA_OPTIONS to a real config

There are two boards, MIP405 and MIP405T that have a few differences.
Start by checking for CONFIG_TARGET_MIP405.  Then introduce
CONFIG_TARGET_MIP405T and use that not CONFIG_MIP405T.  Next, convert
also convert the usage of CONFIG_ISO_STRING to be based on Kconfig.
