* Automatically include config.hDan Crowell2019-12-063-7/+3
| | | | | | | | | | | | | | | | | | Rather than having to remember to include config.h anywhere we reference a CONFIG variable (and usually forgetting), this adds it to the default compiler flags so that it gets included in every source file we build.

* sio: Add test for availabilityAndrew Jeffery2018-10-151-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some components can continue to operate in the face of the SuperIO controller being unavailable on the LPC bus (specifically, the UART and boot flag processing). Other components require it present (AST-based SFC implementations and the AST mailbox). Components in the latter category can just fail with an errl when they attempt to access the controller, but for those in the former category we add an isAvailable() function in the SIO namespace to sidestep dealing with errors. Specifically, isAvailable() tests for the expected error when the SuperIO controller is disabled, and returns an errlHndl_t if any other error occurs. This way true LPC errors are propagated to the caller to commit as desired. For the moment *all* errors produced by the SIO::isAvailable() LPC bus access will result in the SIO code assuming the device is absent. We should be more precise about this, but the hardware behaviour seen under hostboot currently prevents us from being more specific. This problem is highlighted by a FIXME block in the implementation of SIO::isAvailable().

* Revert "sio: Add test for availability - LPC error tweak"Andrew Jeffery2018-10-151-15/+0
| | | | | | | | | | | | | | | | | | This reverts commit 627379aeaa27e30d66ebb0aecf218708d465162c, which incorrectly attempted to account for LPC errors during testing for SIO absence. The broken patch interprets the OPBM status as LPCHC status and expects an LPCHC SYNC Abnormal error, however as it's the OPBM status that indicates the error we never hit the LPCHC error path to populate the errl with the error RC expected by the SIO driver.

* bootconfig: Describe pnor boot flagsJoel Stanley2018-07-102-2/+44
| | | | | | | | | | | | | | | | | | | | The reserved boot flag is now used by a BMC to signal to the host firmware that it supports the mbox protocol[1]. Currently this has no affect on Hostboot, but in the future it will be used by skiboot. In the future hostboot could chose to use the mbox protocol to read and write PNOR.
