[PATCH 0/3] add PBL handoff-data support

[Sascha Hauer <s.hauer@pengutronix.de>]

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.

  ARM: move blob_is_arm_boarddata() to include
  add handoff-data support
  ARM: pass handoff data from PBL to proper
