imd: make it work on big-endian machines ...

The commit

    commit 5e33577
    Author: Sascha Hauer <s.hauer@pengutronix.de>
    Date:   Tue Mar 29 10:06:46 2016 +0200

        imd: use struct imd_header * as argument

introduces additional imd type checks like this

    if (!imd_is_string(imd->type))
           return NULL;

These checks work incorrectly on any big-endian machine
because the imd->type field needs addition conversion
to little-endian byteorder before use.

Here is the imd command output on big-endian qemu-malta:

    barebox:/ imd /dev/nor0.barebox
    release: <NULL>
    build: <NULL>

This patch fixes the problem by adding necessary conversion
via imd_read_type().

reset_source: export reset_source_set_priority ...

In commit 4a7534bf07e ("reset-source: Allow different priorities") the

Do that change in EXPORT_SYMBOL() accordingly.
reset_source_set still exists but is a static inline now.

bootm: Optionally add a root= option to Kernel command line ...

It becomes a common case that the Kernel is loaded from the filesystem

automatically append the root= option to the kernel command line. This
is done when global.bootm.appendroot is true.

Kconfig: Create Kconfig symbol for NVVAR ...

nvvar support not only needs globalvar, but also persistent
environment storage. Add a separate default-y option which
depends on ENV_HANDLING for this case. Make the option visible

and add a help text to make this decision easier.

Kconfig: Make ENV_HANDLING visible ...

ENV_HANDLING is usable even without explicit loadenv/saveenv command
support. Instead of selecting this option from loadenv/saveenv, make
this option visible. loadenv/saveenv can then depend on ENV_HANDLING
rather than selecting it. This reduces Kconfig dependencies hassles.

Kconfig: Make GLOBALVAR visible ...

Currently global environment variables are only enabled when the

state: Fix Kconfig dependencies ...

State support does not need OF_BAREBOX_DRIVERS and never did, so drop
the dependency there. It's the state driver which needs of_find_path(),
since this symbol now is always enabled when OF is enabled, we don't
have to add the dependency to the state driver, but instead can depend
on OFDEVICE. We could depend on OF instead, but compiling the state
driver without OFDEVICE makes no sense.

fix erasing/protecting flashes with unspecified size ...

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.

stdio: Replace FILE functions with filedescriptor functions ...

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.
