[PATCH 0/8] add generic EFI timer

[Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>]

Hi,

	On EFI you have 3 ways to get to do "timer"

	1: Simply by waiting X us and calling Boot Service udelay

	2: By using event

	3: By use the Timestamp GUID

	for barebox this would be the best but even on EDK II this is never
	ever compiled on any target.

	So we have 2 choice, use a Hardware specific timer or implement the
	timer using timestamp

	This pull request allow you to enable 2 timers and use the best one at
	runtime.

	EFI x86 (HW specific)
	EFI Generic (based on Event)

please pull
