These patches introduce sbe fifo driver for getmem/putmem.  It's based on
Ben's original incomplete patches.  The sbe fifo driver also parses ffdc in
case of any errors and dumps the ffdc data.  It should be easy to add other
chip-ops using the infrastructure in sbefifo.c

Other related changes include:
  - Convert kernel pib backend to use /dev/scom*

  - Fixing bug in putmem
    Do a single read of data from stdin and then do a single memory write.
    This avoids the address offset error.

  - Reorganize code in _putmem to be similar to _getmem
    This means if we fail to write memory using one target, we can try again
    with another target.


Amitay Isaacs (5):
  mem: Read all the memory before call mem_write
  mem: Make _putmem consistent with _getmem
  libpdbg: Replace warn/err with PR_WARNING/PR_ERROR
  libpdbg: Add interface to BMC kernel sbefifo driver
  main: Use sbefifo first before adu for memory read/write

Benjamin Herrenschmidt (2):
  target: Store "fd" for struct pib
  libpdbg: Add bmc /dev/scom* backend
