* pnor: Fall back to AST mbox transport if IPMI is unavailableAndrew Jeffery2018-10-101-50/+19
| | | | | | | | | | | | | Avoid a flag-day transition by allowing for old BMC releases. Eventually support for the AST mailbox will be removed and the indirection with it.

* pnor: mboxdd: Rename class to PnorMboxDDAndrew Jeffery2018-10-101-4/+4
| | | | | | | | | | | | | | The rename is in preparation for introducing the fallback code, which needs to know of both the IPMI and AST mailbox implementations.

* pnor: Introduce an IPMI-based PNOR driver implementationAndrew Jeffery2018-10-101-2/+2
| | | | | | | | | | | | | | | | | | Similar to the AST MBOX implementation, the IPMI PNOR implementation negotiates the layout of the LPC FW space with the BMC, but using IPMI rather than the AST mailbox as a protocol transport. The same protocol is still used and has simply been adapted to the new interface. Note that currently the change of transport has had a 2-3x impact on boot performance. Optimisation is an ongoing effort.

* pnor: Add AST Mailbox protocol supportBenjamin Herrenschmidt2017-05-011-0/+258
This adds a new alternative PnorDD that uses the Asped AST Mbox protocol as supported by OpenBMC.
