Make the virtio ring code resilient against corruption of the buffers
shared with the device.
It follows the example of Linux by keeping a private copy of the
descriptors and metadata for state tracking and only ever writing to the
descriptors that are shared with the device. I was able to test these
hardening steps in the sandbox by simulating device writes to the
queues.
Add a regression test for virtio-rng reading beyond the end of its
buffer if the virtio device provides an invalid length.

Check the length of data written by the device is consistent with the

Virtio tests that find a child device require the virtio device driver

The virtqueue is passed to virtio_notify() so move the virtqueue
deletion to the end of the test when it's no longer needed. This wasn't

do anything for notifications, but it could cause problems if things
change and it was a bad example.

The bi_enetaddr field in struct bd_info is write-only; nothing ever
reads back the value.
Moreover, the value we write is more or less random, and certainly not
something one can rely on: If the board has a writable environment and
the mac address has been stored there, we fetch that value. But if the
board doesn't, this code runs before initr_net() -> eth_initialize(),
and thus before the code in eth-uclass which fetches MAC addresses
from eeprom, fuses or whatnot and populates the (run-time) environment
with those values.

Linux determines its console based on several sources:
1. the console command line parameter
2. device tree (e.g. /chosen/stdout-path)
3. various other board- and arch-specific sources
If the console parameter specifies a real console (e.g. ttyS0) then that is
used as /dev/console. However, if it does not specify a real console (e.g.
ttyDoesntExist) then *nothing* will be used as /dev/console.
Reading/writing it will return ENODEV. Additionally, no other source will
be used as a console source.
Linux commit ab4af56ae250 ("printk/console: Allow to disable console output
by using console="" or console=null") recently changed the semantics of the
parameter. Previously, specifying console="" would be treated like
specifying some other bad console. This commit changed things so that it
added /dev/ttynull as a console (if available). However, it also allows
for other console sources. If the device tree specifies a console (such as
if U-Boot and Linux share a device tree), then it will be used in addition
to /dev/ttynull. This can result in a non-silent console.
To avoid this, explicitly set ttynull as the console. This will disable
other console sources. If CONFIG_NULL_TTY is disabled, then this will have
the same behavior as in the past (no output, and writing /dev/console
returns ENODEV).

Asking if the alias we found actually points at the device tree node
we passed in (in the guise of its offset from blob) can be done simply
by asking if the fdt_path_offset() of the alias' path is identical to
offset.
In fact, the current method suffers from the possibility of false
negatives: dtc does not necessarily emit a phandle property for a node
just because it is referenced in /aliases; it only emits a phandle
property for a node if it is referenced in <angle brackets>
somewhere. So if both the node we passed in and the alias node we're
considering don't have phandles, fdt_get_phandle() returns 0 for both.
Since the proper check is so simple, there's no reason to hide that
behind a config option (and if one really wanted that, it should be
called something else because there's no need to involve phandle in
the check).

ARM semihosting provides no provisions for determining if there is
pending input. The only way to determine if there is console input is to
do a read (and block until the user types something). For this reason,
we always return true for tstc (since you will always get input if you
try). However, this behavior can cause problems for code which expects
tstc to eventually be empty. In query_console_serial, there is the
following construct:
/* empty input buffer */
while (tstc())
getchar();
with the current implementation, this effectively turns into an infinite
loop. To avoid this, fake tstc by returning false half of the time. This
is generally OK because the other common construct looks like
do {
if (tstc())
process(getchar());
} while (!timeout());
so it's fine if we only read a new character every other loop. This will
break things like CYGACC_COMM_IF_GETC_TIMEOUT, but that could be
reworked to test on the timeout instead of calling tstc again (and
ymodem over semihosted serial is not that useful in the first place).

This adds support for signing images in auto-generated FITs. To do this,
we need to add a signature node. The algorithm name property already has
its own option, but we need one for the key name hint. We could have
gone the -G route and added an explicit name for the public key (like
what is done for the private key). However, many places assume the
public key can be constructed from the key dir and hint, and I don't
want to do the refactoring necessary.
As a consequence of this, it is now easier to add public keys to an
existing image without signing something. This could be done all along,
but now you don't have to create an its just to do it. Ideally, we
wouldn't create a FIT at the end. This could be done by calling
fit_image_setup_sig/info.crypto->add_verify_data directly.
