Some network devices, especially when connected to a switch, are
connected via a fixed link. This patch adds support for a fixed phy
configured through device tree.
TODO: Add support for the "speed" and "full-duplex" properties.

It becomes a common case that the Kernel is loaded from the filesystem
which later becomes the rootfs. This adds a possibility to let bootm
automatically append the root= option to the kernel command line. This
is done when global.bootm.appendroot is true.

We have at least two places which convert a string to a boolean type,
so create a common function for this. strtobool treats
- any positive (nonzero) number as true
- "0" as false
- "true" (case insensitive) as true
- "false" (case insensitive) as false
Every other value results in an error and the input *val is not
modified. The caller is expected to initialize *val with the correct
default before calling strtobool.

I.MX6+ version of the silicon exposed PCIe core's reset signal as a bit
in one of the control registers. As a result using old, pre-i.MX6+,
reset sequence on i.MX6+ leads to Barebox hanging during startup. Using
exposed reset bit instead solves the problem.

fixes: 81737c1 mtd: Fix erasing of devices >4GiB
Several places erased a complete flash partition passing ~0 as count to
erase(). With the above commit count to erase was changed from an unsigned
type to a signed type, so the (count > f->size - offset) check in
erase() no longer triggers and the ~0 count is no longer adjusted to the whole
device size. Among other things this results in saveenv failures on NOR
flashes.
This patch fixes this by introducing an explicit macro for erasing the
whole device which is tested for in erase(). All other negative values
are rejected.

We have defined stdin, stdout and stderr as integer file descriptors,
but normally they should be FILE *. Also fprintf, fputc and fputs take
file descriptors instead of FILE *. As FILE * are inconvenient in the
barebox environment replace the f* functions with the corresponding d*
functions. dprintf is POSIX conform whereas dputc and dputs are barebox
specific, but do not conflict with any stdc function. fgetc is unused
and can be removed without replacing it.

We have a shortcut for fprintf(stderr, so use it. This is done to

This moves the function prototypes in include/fs.h which also exist
in the libc to the locations they would have in libc.
With this it becomes easier to share code between barebox and userspace
since the usual libc include files will exist. Also users of the libc
functions no longer have to include the barebox internal fs.h header.

Our asprintf and vasprintf have different prototypes than the glibc
functions. This causes trouble when we want to share barebox code
with userspace code. Change the prototypes for (v)asprintf to match
the glibc prototypes. Since the current (v)asprintf are convenient
to use change the existing functions to b(v)asprintf.

Some SoCs allow to store multiple boot images on a device in order to
improve robustness. This adds a -r option to barebox_update to indicate
we do not want to make an update but instead repair/refresh an existing
image. Handlers which want to support this feature must set the
BBU_HANDLER_CAN_REFRESH flag during registration.

We want to extend the functionality of the ubi detach function,
but we don't want to change the original detach function to make
UBI updates easier. This adds a barebox specific detach function
which encapsulates the original UBI function. Also this makes the
original ubi detach function internal to ubi.

This updated code supports recovering from unclean unmounts when write
buffer size is larger than 8. Linux uses takes information into
consideration when checking for writes.
The following list shows the changes for each file done compared to
u-boot v2016.03 code.
Makefile
* Add gc.o, do not include header as in u-boot
budget.c:
* Replace __UBOOT__ with __BAREBOX__
debug.c:
* Replace __UBOOT__ with __BAREBOX__
* Remove #include <linux/compat.h>

U-Boot essentially disabled pr_crit output and dump_stack() is defined
to do { } while (0), so ubifs_assert does nothing despite condition.
