[Pdbg] [PATCH 0/3] Add i2c put and get to pdbg

[Rashmica Gupta]

At the moment we only support multiples of 4 bytes. So if you just want to
set the device to read from it you need to do something like:
./pdbg  -P i2cm puti2c 0 0x50 10 3 0x000000  (the device addr counts as a byte)


The i2c reset function doesn't work as well as I would like... Sometimes
if you try to read from devices that don't exist, you can no longer read
from devices that do exist - using the reset func in skiboot (by doing 
i2ctransfer from i2ctools on the host or a reboot) or resetting the lbus
(./pdbg -P fsi0 -D4 putcfam 0x80d 0x20000000) sometimes but not always
fixes things.

  libpdbg: use i2ctools lib
  libpdbg: Add i2c get and put functions for i2c master on CFAM
  libpdbg: Add i2c get and put for i2c masters on the PIB
