The boot parameter table index memory address for J721E was configured
to an incorrect value which prevented the use of this definition to
determine which boot parameter table is active which is needed to be
able to distinguish between primary and backup boot modes. Fix this
issue by updating the value to the correct one also in alignment with
the J721E Technical Reference Manual (TRM).

Keystone2 u-boot loads the initrd image into non-LPAE addressed memory
but linux kernel is running in LPAE. This causes a conflict as kernel
detects that non-memory address is passed and kernel ignores initrd.
There is an existing fixup logic to modify the address in the proper
configuration, but this is disabled at the moment. Enable the fixup
by setting the env variable for this so that initrd can be used
properly.

On am571x-idk there can be following configurations based on Jumper J51
and LCD panel detected.

1) J51 removed (6port): 6 port Ethernet. Disable LCD panel.
2) J51 placed (LCD) + Panel detected: 4 port Ethernet with appropriate LCD.
3) J51 placed (LCD) + Panel not detected/not supported.

Configuration 3 is considered invalid as we can't use display nor ICSS1
ethernet ports due to hardware muxing. Alert the user to fix the
configuration and prevent boot.

Alternative was to allow boot and limit to 4 port Ethernet with no display
but this involved introduction of another DTB for the kernel and was
considered not worth the hassle.

When running our tests there are some cases where as part of the Python
2.7 to Python 3.6 migration we didn't force Python 3.6 to be used as
everything wasn't yet migrated.  Now that everything is, make sure to
tell virtualenv to use python3.  In the case of Travis this is best done
by making the tools test happen after the main tests so that it will
already have been run in all cases, TEST_PY_TOOLS is a subset of

In the first version, the result of malloc is checked
with ut_assertnonnull. But on a fail, this macro exit
the function, so previously malloc are not freed.

So to avoid a memleak, we don't use ut_assertnonnull,
but simply check the return of malloc. If one has failed,
we freed all the allocated memory and quit the function.

Currently the size of pci_addr_t and pci_size_t depends on
CONFIG_SYS_PCI_64BIT. For qemu_arm64_defconfig with 4 GiB RAM this leads
to an error

    pci_hose_phys_to_bus: invalid physical address

which is due to the truncation of the bus address in _dm_pci_phys_to_bus.

Defining CONFIG_SYS_PCI_64BIT is not a solution as this results in an error

   PCI: Failed autoconfig bar 10

So let's use unsigned long for pci_addr_t and pci_size_t if
CONFIG_SYS_PCI_64BIT is not defined.

Considering that 32bit U-Boot is used to launch some 64bit x86 systems we
cannot do without CONFIG_SYS_PCI_64BIT requiring u64 as type.

As usual a bit late a couple of tiny fixes and improvements for ARC.

1. Switch from ARC UART to a convenient DW UART on ARC
   simulation platforms. This became avaialble when nSIM got support
   of that much more standard UART (starting from nSIM v2019.06).
   FWIW also available now in Free nSIM [1].

   This among other things allows us finally to use the same one binary
   on all our simulators & FPGA-based emulators.

2. Disable networking support on simulated platforms as there's no
   network interface in them.

3. Add Virtio net & block devices for the configuration supported
   by QEMU so that we may leverage those virtual peripherals and
   in fact it's possible to load uImage from TFTP server and bootm it.

4. Minor fixes for HSDK clocks.

5. Rework of how we chose and use compiler options for ARC-based boards.
   In real world ARC-based designs are customized more or less but very
   rarely match any of our "templates" thus it makes not much sense to
   pretend we have some fixed configs, instead we now will fully reply
   on a SoC or even board on getting precise set of compiler options
   preferably even extracted from real HW via "tcfgen" utility.

6. Well and finally yet another simplification - switch to generic
   written in C accessors which are much more universal and just work
   for any target supported by the complier as compared to GAS
   implementation which is much more target-dependent.

   This one was heavily "inspired" by similar implementation for RISCV
   and ARM.

First of all U-Boot is not that performance oriented as real run-time
software like OS or user bare-metal app so we may afford being not super
fast as we only being executed once. That in return allows us to be more
universal and support wider variety of devices.

And looking forward that will significantly reduce maintenance and simplify
support of newer architectures.

And while at it we add quad-word accessors like readq(), writeq() etc.

It's a very rare if at all existing occasion when ARC CPU template
is used as is w/o any changes - in the end it's a beauty and competitive
advantage of ARC cores to be tailored for a particular use-case - and
so it doesn't make a lot of sense to offer template-based "-mcpu" selection.
Given for each and every platform we end-up adding quite a few more flags
it's logical to move "-mcpu" selection to platform's definition as well
which we exactly do here.

The commit e8e9715d ("regulator: fixed: Modify enable-active-high behavior")
fixed the regulator driver behavior when 'enable-active-high' is defined.
Unfortunately, this patch used dm_regulator_platdata()'s "boot_on" member
to set GPIOD_IS_OUT_ACTIVE flag and enable the regulator.

The issue here is that regulator_common_ofdata_to_platdata() is called
_before_ regulator_pre_probe() function in which the 'regulator-boot-on'
property is asserted.

As a result the GPIOD_IS_OUT_ACTIVE flag is not set and gpio_request_by_name()
called in the former function is not enabling the regulator.
This is problematic for e.g. i.MX ethernet driver, which then tries to
perform initialization without power (and fails).

The solution here is to explicitly enable regulator in regulator_pre_probe()
callback only when 'regulator-boot-on' property is present in device tree.
The GPIOD_IS_OUT_ACTIVE flag is not set at all, but relevant gpio is
requested.
