[Pdbg] [PATCH 00/17] Rework sbefifo library and driver

[Amitay Isaacs]

The current implementation of libsbefifo assumes kernel device driver based
transport for sbefifo.  However, it's possible to use other transport
mechanism (e.g. cronus) to talk to sbefifo.  In order to use other transports,
sbefifo library must provide the protocol marshalling required for various
chip-ops.

The transport for sbefifo is abstracted as a sbefifo_transport hwunit.  This
results in a single implementation of sbefifo hwunit that performs the
chip-ops.  The sbefifo-mem hwunit, uses the sbefifo hwunit to do the chip-op.

Amitay Isaacs (17):
  libpdbg: Only real nodes should have "system-path" property
