* Ignore LPC and XSCOM BARs from BLDan Crowell2017-06-071-0/+5

* Map BAR attributes based on data from BootloaderDan Crowell2017-06-021-1/+37
| | | | | | | | | | | | | | | | | | | | | | | | | If the master processor has no memory behind it the entire memory map must be modified. Each processor has its own statically defined map that covers both memory and MMIOs. If the master has no memory, its memory map is swapped with another processor. Each processor gets a new effective fabric id that is then used to compute all of the BAR values for those processors. The SBE boots with a certain memory map programmed into the master processor. That value is then passed up through the bootloader into Hostboot. This value is compared to the BAR values that Hostboot assumes it is using. Based on that comparison, various attributes are computed to match the effective fabric positions.

* Restrict timebase sync to once per core.Patrick Williams2014-07-172-5/+11
| | | | | | | | | | | | | | | | | | | | | As part of Id3a3bc0b7367e61f2725af17975fe3ba068f69a9, I fixed the deferred work queue to not leak work objects if there are multiple objects. When cores wake up, each thread inserts a work object to synchronize its timebase. Now that they are not leaking, we are running this 8 times, which is causing enough clock drift that we are getting passed the timeout for core wakeups. Modify deferred work queue to allow us to skip performing work if there is already an outstanding deferred work object. This will return us to running the timebase sync just once.
