phosphor-ipmi-flash making progress!

[Patrick Venture]

For those interested parties, phosphor-ipmi-flash which provides a
variety of out-of-band mechanisms for updating the BMC in a
fully-configurable manner is nearly ready for wide distribution.

Currently supported: aspeed-p2a-ctrl (ipmipci), and inband (ipmibt)*
Shortly supported: aspeed-lpc-ctrl (ipmilpc)

*There is a bug in the transmit buffer size depending on whether it's
over KCS versus actually BT since BT has a smaller buffer requirement.

UBI Tarball updates aren't yet supported, but that's only a matter of
someone writing an update handler.  The firmware handler on the BMC
can be extended easily to support a variety of verification and update
mechanisms.  The default behavior is to leverage a service for each of
these things.  One can implement whatever they really want for each
service.

The file sent to the BMC isn't required to have a signature file.  One
could simply skip sending the hash file and have a verification step
that doesn't do anything special.  So, it's very flexible.

Here's some output:

$ ./phosphor_ipmi_flash_tool --command update --interface ipmipci
--image image-bmc --sig image-bmc.sig

Sending over the firmware image.
