447240e27b android: boot: boot image header v3, v4 do not support recovery DTBO
android_image_get_dtbo() is used to get recovery DTBO via abootimg cmd.
This is not supported in boot image header v3 and v4. Thus, print an
error message when v1,v2 header version are not used.

f48efa0edb android: boot: kcomp: support andr_image_data
andr_image_data structure is used as a global representation of
boot image header structure. Introduce this new structure to
support all boot header versions : v0,v1.v2.v3.v4 and to support
v3 and v4 while maitaining support for v0,v1,v2.
The need of using andr_image_data comes from the change of header
structure in both version 3 and 4.

Rework android_image_get_kcomp()  to support this new struct.

9c6d57dc7e qemu: Add a bootmeth for qfw
This supports reading a kernel and ramdisk from qfw, then loading it with
either the booti or bootz commands.

22353fa6b5 bootstd: Add some default filesystems and commands
We need to support a basic set of filesystems for booting to work in most
cases. Add these in via a new option, letting the board disable them
individually (for space reasons) if desired.

This enables the filesystem commands as well as the actual functionality,
even though bootstd is quite happy to use ext4 without the ext4 command.
Further work would be needed to disintangle this and reduce code size.

Add several other options as well, providing sensible defaults.

We cannot enable this by default, since it expands the size of many
boards quite a lot.

47aedc29dc bootstd: Switch bootdev scanning to use labels
At present we set up the bootdev order at the start, then scan the
bootdevs one by one.

However this approach cannot be used with hunters, since the bootdevs may
not exist until the hunter is used. Nor can we just run all the hunters at
the start, since that violate's U-Boot's 'lazy init' requirement. It also
increases boot time.

So we need to adjust the algorithm to scan by labels instead. As a first
step, drop the dev_order[] array in favour of a list of labels. Update the
name of bootdev_setup_iter_order() to better reflect what it does.

Update some related comments and log messages. Also disable a few tests
until a later commit where we can use them.
