This patch makes sure that the flush/invalidate_dcache_range() functions
can handle corner-case calls like this -- invalidate_dcache_range(0, 0, 0);
This call is valid and is happily produced by USB EHCI code for example.
The expected behavior of the cache function(s) in this case is that they
will do no operation, since the size is zero.

The current implementation though has a problem where such invocation will
result in a hard CPU hang. This is because under such conditions, where the
start_addr = 0 and stop = 0, the addr = 0 and aend = 0xffffffe0 . The loop
will then try to iterate over the entire address space, which in itself is
wrong. But iterating over the entire address space might also hit some odd
address which will cause bus hang. The later happens on the Atheros MIPS.

The existing 8x16 font is adequate for most purposes. It is small and fast.
However for boot screens where information must be presented to the user,
the console font is not ideal. Common requirements are larger and
better-looking fonts.

This console driver can use TrueType fonts built into U-Boot, and render
them at any size. This can be used in scripts to place text as needed on
the display.

This driver is not really designed to operate with the command line. Much
of U-Boot expects a fixed-width font. But to keep things working correctly,
rudimentary support for the console is provided. The main missing feature is
support for command-line editing.

With anti-aliased fonts we need a more fine-grained horizontal position

To cope with this, use fractional units (1/256 pixel) for horizontal
positions in the text console.

wish to test multiple DFU configurations (e.g. SD card ext4 filesystem, SD
card whole raw partition, RAM, etc.), but don't want to test every
single transfer size on each, to avoid bloating the overall time taken by
testing. If the boardenv doesn't specify a set of sizes, the built-in list
is used as a default, preserving backwards-compatibility.

Currently, bad patterns are only honored when executing a shell command.
Other cases, such as the initial boot-up of U-Boot or when interacting
with command output rather than gathering all output prior to the shell
prompt, do not currently look for bad patterns in console output. This
patch makes sure that bad patterns are honored everywhere.

One benefit of this change is that if U-Boot sandbox fails to start up,
the error message it emits can be caught immediately, rather than relying
on a (long) timeout when waiting for the expected signon message and/or
command prompt.

When pytest generates the name for parametrized tests, simple parameter
values (ints, strings) get used directly, but more complex values such
as dicts are not handled. This yields test names such as:

    dfu[env__usb_dev_port0-env__dfu_config0]
    dfu[env__usb_dev_port0-env__dfu_config1]

Add some code to extract a custom fixture ID from the fixture values, so
that we end up with meaningful names such as:

    dfu[micro_b-emmc]
    dfu[devport2-ram]

If the boardenv file doesn't define custom names, the code falls back to
the old algorithm.

The existing net test executes a list of commands supplied by boardenv
variable env__net_pre_commands. The idea was that boardenv would know
whether the Ethernet device was attached to USB, PCI, ... and hence was
the best place to put any commands required to probe the device.

However, this approach doesn't scale well when attempting to use a single
boardenv across multiple branches of U-Boot, some of which require "pci
enum" to enumerate PCI and others of which don't, or don't /yet/ simply
because various upstream changes haven't been merged down.

This patch updates the test to require that the boardenv state which HW
features are required for Ethernet to work, and lets the test itself map
that knowledge to the set of commands to execute. Since this mapping is
part of the test script, which is part of the U-Boot code/branch, this
approach is more scalable. It also feels cleaner, since again boardenv
is only providing data, rather than test logic.

Currently, the distro boot commands always enumerate USB devices before
performing network operations. However, depending on the board and end-
user configuration, network devices may not be attached to USB, and so
enumerating USB may not be necessary. Enhance the scripts to make this
step optional, so that the user can decrease boot time if they don't
need USB.

This change is performed by moving the "usb start" invocation into a
standalone variable. If the user desires, they can replace that
variable's value with some no-op command such as "true" instead.

Booting from a USB storage device always needs to enumerate USB devices,
so this action is still hard-coded.
