When doing a 'boot friesel net' one expects a message when 'friesel'
does not give any bootable results and thus 'net' is booted. This patch
adds this message.

When no targets to boot are found it can happen that the boot command
just returns silently. Explicitly print a message in this case to give

We have a struct bootentries type to collect different boot entries,
so use this to pass around data between functions rather than using
an array of strings. With this we also no longer have to convert a
string to a boot entry multiple times.

This completes the separation of the blspec code from the boot
code. With this the boot code only handles generic boot entries
of type struct bootentry which are embedded into the type
(blspec/bootscript) specific structs.

We currently have to special case blspec entries vs. boot scripts
in the common boot code since we want to print different informations
about them. This adds a 'title' and 'description' which can be filled
in with different information by bootscripts and blspec entries and
so we get rid of the special handling.
Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
The code in common/boot.c collects the different boot entries in
lists of type struct blspec, eventhough many of them may not be
bootloader spec entries but for example boot scripts. This is the first
step of separating the data structures from boot entries and bootloader
spec: As struct blspec is merely a container for collecting boot entries
We simply rename struct blspec to struct bootentries. No functional change.

Now that the bootm code can be used without the command, we have to
move the magicvar descriptions from the command code to the common
bootm code aswell.
Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
bootm has a C API, so the bootm options have to depend on the
option providing the bootm code (CONFIG_BOOTM), not on the
option providing the command (CONFIG_CMD_BOOTM). Fixing the
dependencies makes it possible to fully use bootm from C without
enabling the bootm command support.
This also removes the CMD_ prefix from the options which means
we have to update the defconfigs aswell.

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

is done when global.bootm.appendroot is true.

nvvar support not only needs globalvar, but also persistent

ENV_HANDLING is usable even without explicit loadenv/saveenv command

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*

specific, but do not conflict with any stdc function. fgetc is unused
