cpu/amd/agesa/Kconfig: Select LAPIC_MONOTONIC_TIMER
Thanks to Aaron Durbin coreboot provides monotonic timers. Select the LAPIC monotonic timer for the AMD AGESA CPUs.
The following is an excerpt from serial log of the ASRock E350M1.
$ grep usec seriallog-20130502_100902.log 01.016: Root Device init 1578 usecs 01.029: CPU_CLUSTER: 0 init 112415 usecs 01.029: PCI: 00:00.0 init 3240 usecs 01.088: PCI: 00:01.0 init 104572 usecs 01.088: PCI: 00:01.1 init 1663 usecs 01.088: PCI: 00:11.0 init 1662 usecs 01.088: PCI: 00:14.0 init 1662 usecs 01.088: PCI: 00:14.3 init 8665 usecs 01.088: PCI: 00:14.4 init 1665 usecs 01.088: PCI: 00:18.0 init 1662 usecs 01.088: PCI: 00:18.1 init 1663 usecs 01.088: PCI: 00:18.2 init 1663 usecs 01.088: PCI: 00:18.3 init 1663 usecs 01.088: PCI: 00:18.4 init 1663 usecs 01.088: PCI: 00:18.5 init 1665 usecs 01.088: PCI: 00:18.6 init 1664 usecs 01.088: PCI: 00:18.7 init 1663 usecs 01.088: PNP: 002e.2 init 1576 usecs 01.088: PNP: 002e.5 init 1577 usecs 01.088: PNP: 002e.a init 1590 usecs 01.088: PNP: 002e.b init 30144 usecs 01.088: PCI: 03:00.0 init 1663 usecs
So the graphics device needs around 100 ms for being initialized.
The full serial log is in the Gerrit comments.
