This series offers an optimization of the Android image loading procedure.

The first patch introduces a new 'abootimg load' command, which loads
partitions from storage into memory. It uses malloc() to find a free
memory region, whereas previously, the developer had to find a free
memory region by himself.

The remaining patches reduce boot time by avoiding extra disk activity.

The second patch implements get_preloaded_partition(), which picks a
partition from memory previously loaded by the 'abootimg load' command.

The third patch optimizes the 'abootimg load' command by skipping zeros
loading at the partition's end.

Roman Stratiienko (3):
  abootcmd: Add load subcommand
  avb: Implement get_preloaded_partition callback
  abootimg: Implement smart image load feature
