2015-01-04ipq8064: Add work around for slow timer clockVadim Bendebury
Libpayload libc requires timer clock frequency to be at least 1MHz. Ipq8064 code presently provides a single option of 32kHz. Pretend to be running at 1 MHz without additional accuracy. This is a hack which will be reverted as soon as the SOC is configured to supply a faster running clock.

2015-01-04libpayload: ipq8064: Add rudimentary timer driverVadim Bendebury
This is still using the 32kHz timer coreboot uses. A finer granularity timer implementation for 806x is in the works. BUG=chrome-os-partner:27784,chrome-os-partner:28880 TEST=none yet.

These drivers are needed right away and never really fit into depthcharge's driver model anyway. CQ-DEPEND=CL:194064 BUG=None TEST=Built and booted nyan, link, and peach_pit and verified that timer values in cbmem were reasonable. Built for nyan_big, nyan_blaze and daisy.
