[PATCH 0/3] add PBL handoff-data support
We need to pass data from the PBL to barebox proper. Right now we do this with passing the data in registers which is quite limited. As the amount of information that has to be passed increases it's time to overcome this limitation. This series introduces handoff-data which is a linked list of memory blobs that can be passed from PBL to barebox proper. Board and SoC code can append this list with their own entries and pick them up later in barebox proper. The ARM architecture is converted over to use handoff data, other architectures could follow.
