malloc: work around some memalign fragmentation issues
Use of memalign can trigger fragmentation issues such as:
// Internally, this needs to find a free block quite bit larger than s.
// Once the free region is found, any unaligned "padding" immediately
// before and after the block is marked free, so that the allocation
// takes only s bytes (plus malloc header overhead).
p = memalign(a, s);
// If there's little fragmentation so far, this allocation is likely
// located immediately after p.
p2 = malloc(x);
free(p);
// In theory, this should return the same value for p. However, the hole
// left by the free() call is only s in size (plus malloc header overhead)
// whereas memalign searches for a larger block in order to guarantee it
// can adjust the returned pointer to the alignment requirements. Hence,
// the pointer returned, if any, won't be p. If there's little or no space
// left after p2, this allocation will fail.
p = memalign(a, s);
In practice, this issue occurs when running the "dfu" command repeatedly
on NVIDIA Tegra boards, since DFU allocates a large 32M data buffer, and
then initializes the USB controller. If this is the first time USB has
been used in the U-Boot session, this causes a probe of the USB driver,
which causes various allocations, including a strdup() of a GPIO name
when requesting the VBUS GPIO. When DFU is torn down, the USB driver
is left probed, and hence its memory is left allocated. If "dfu" is
executed again, allocation of the 32M data buffer fails as described
above.
In practice, there is a memory hole exactly large enough to hold the 32M
data buffer than DFU needs. However, memalign() can't know that in a
general way. Given that, it's particularly annoying that the allocation
fails!
The issue is that memalign() tries to allocate something larger to
guarantee the ability to align the returned pointer. This patch modifies
memalign() so that if the "general case" over-sized allocation fails,
another allocation is attempted, of the exact size the user desired. If
that allocation just happens to be aligned in the way the user wants,
(and in the case described above, it will be, since the free memory
region is located where a previous identical allocation was located),
the pointer can be returned.
This patch is somewhat related to 806bd245b1ab "dfu: don't keep
freeing/reallocating". That patch worked around the issue by removing
repeated free/memalign within a single execution of "dfu". However,
the same technique can't be applied across multiple invocations, since
there's no reason to keep the DFU buffer allocated while DFU isn't
running. This patch addresses the root-cause a bit more directly.
This problem highlights some of the disadvantages of dynamic allocation
and deferred probing of devices.
This patch isn't checkpatch-clean, since it conforms to the existing
coding style in dlmalloc.c, which is different to the rest of U-Boot.

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

video: Add a console driver that uses TrueType fonts
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.

video: Provide a backspace method
With proportional fonts the vidconsole uclass cannot itself erase the
previous character. Provide an optional method so that the driver can
handle this operation.

video: Use fractional units for X coordinates
With anti-aliased fonts we need a more fine-grained horizontal position
than a single pixel. Characters can be positioned to start part-way through
a pixel, with anti-aliasing (greyscale edges) taking care of the visual
effect.
To cope with this, use fractional units (1/256 pixel) for horizontal
positions in the text console.

video: Add stb TrueType font renderer
This is a header file which provides a fairly light-weight TrueType
rendering implementation. It is pulled from http://nothings.org/. The code
style does not comply with U-Boot but I think it is best to leave alone to
permit the source to be synced later if needed.
The only change is to fix a reference to fabs() which should route through
a macro to allow U-Boot to provide its own version.
