With this we can do 'boot <name>' where name is one of:
- a filename under /env/boot/
- a full path to a boot script
- a device name
- a partition name under /dev/
- a full path to a directory which
- contains boot scripts, or
- contains a loader/entries/ directory containing bootspec entries
Multiple names can be given, they are tried in order. So any mixture
between bootspec entries and bootscripts can be given. bootspec entries
can now also be given as a path to a directory containing bootspec entries.

spec entries found in directories.

Instead of only allowing complete devices we now also allow single
partitions to look for bootloader spec entries.
Normally the bootloader spec defines a way to find a partition containing /boot
on a device. On embedded systems it's often useful instead to have only a
single partition image which contains both the kernel and the root filesystems.
This partition image may be written to the device multiple times. With this
patch they can be booted with 'boot emmc0.<partno>'

There is no much sense in having the pinctrl drivers be user selectable
as all arches using on of them already selects the right one.
So to avoid presenting the user with the choice to enable unrelated
pinctrl drivers or pushing lots of dependencies into the Kconfig just
drop the configurability.

There are some reasons for using YAMON-style memory map:
* we can run Linux kernel from barebox;
* we can use GXemul for running barebox.
