We don't use zlib and gzip but do use lzo, so enable this.

This is a convenient way of finding out where boottime is going. Enable
it for coreboot.

While we don't want PCAT timers for timing, we want timer 2 so that we can
still make a beep. Re-purpose the PCAT driver for this, and enable it in
coreboot.

This timer runs at a rate that can be calculated, well over 100MHz. It is
ideal for accurate timing and does not need interrupt servicing.

Tidy up some old broken and unneeded implementations at the same time.

To provide a consistent view of boot time, we use the same time
base as coreboot. Use the base timestamp supplied by coreboot
as U-Boot's base time.

Since the ICH SPI controller uses PCI, we must ensure that PCI is available
before it is inited.

This fixes the current "ICH SPI: Cannot find device" message on boot.

This command is useful for measuring SPI flash load times and the like.
Enable gettime as well to obtain absolute time tick values.
