Implement command--line option --gdbserver COMM, which does two things:
a) Run the sandbox process under gdbserver, using COMM as gdbserver's
communication channel.
b) Disables all timeouts, so that if U-Boot is halted under the debugger,
tests don't fail. If the user gives up in the middle of a debugging
session, they can simply CTRL-C the test script to abort it.
This allows easy debugging of test failures without having to manually
re-create the failure conditions. Usage is:
Window 1:
./test/py/test.py --bd sandbox --gdbserver localhost:1234
Window 2:
gdb ./build-sandbox/u-boot -ex 'target remote localhost:1234'
When using this option, it likely makes sense to use pytest's -k option
to limit the set of tests that are executed.
Simply running U-Boot directly under gdb (rather than gdbserver) was
also considered. However, this was rejected because:
a) gdb's output would then be processed by the test script, and likely
confuse it causing false failures.
b) pytest by default hides stdout from tests, which would prevent the
user from interacting with gdb.
While gdb can be told to redirect the debugee's stdio to a separate
PTY, this would appear to leave gdb's stdio directed at the test
scripts and the debugee's stdio directed elsewhere, which is the
opposite of the desired effect. Perhaps some complicated PTY muxing
and process hierarchy could invert this. However, the current scheme
is simple to implement and use, so it doesn't seem worth complicating
matters.
c) Using gdbserver allows arbitrary debuggers to be used, even those with
a GUI. If the test scripts invoked the debugger themselves, they'd have
to know how to execute arbitary applications. While the user could hide
this all in a wrapper script, this feels like extra complication.
An interesting future idea might be a --gdb-screen option, which could
spawn both U-Boot and gdb separately, and spawn the screen into a newly
created window under screen. Similar options could be envisaged for
creating a new xterm/... too.
--gdbserver currently only supports sandbox, and not real hardware.
That's primarily because the test hooks are responsible for all aspects of
hardware control, so there's nothing for the test scripts themselves can
do to enable gdbserver on real hardware. We might consider introducing a
separate --disable-timeouts option to support use of debuggers on real
hardware, and having --gdbserver imply that option.

The recent change to memalign() caused the allocation failure detection
code to be dead code; the "retry" logic is always activated under the same
condition that the original failure detection code is, and also fully
handles any possible failures. This patch solves the presence of dead
code.
Two alternatives are possible:
a) Delete the now-dead test, and rely on the "retry" path to handle any
allocation problems, as it does.
b) Make the "retry" path fall through to the existing (currently dead)
failure detection code, thus making it not-dead.
(b) was chosen since it reduces the diff between U-Boot's and the upstream
dlmalloc. This should make it marginally easier to import a new version of
dlmalloc in the future.

Without this, builds default to using new Travis CI infra-structure which
does no allow sudo. The builds need sudo in order to install the ELDK
compilers. Consequently, almost all builds fail without this.
I suspect that existing Travis CI users have not noticed this because
their accounts or builds have been grand-fathered into backwards-
compatible default settings, whereas I just set up a new build from
scratch and received new default settings.

The FB address is generated by the firmware running on the GPU/VideoCore
and is a "bus" address. This address is the other side of an IOMMU from
the ARM upon which U-Boot is running. Use bus_to_phys() to convert this
to an ARM physical address. Without this, U-Boot seems to work just fine,
but once the Linux kernel boots on an RPi2, accessing the FB memory often
causes a hard system hang.
