some rockchip soc will not include lib/timer.c in SPL stage,
so implement timer driver for some soc can use us delay function in SPL.

Similar to load an fdt, when loading an initrd about the 512Mb mark
things seem to break. For now force loading below 512Mb until the reason
why this fails has been determined/solved.

There are already Kconfig options for SPI flash drivers, but we
have not moved them from config.h to defconfig files. This commit
does this in a batch.

We have finished Generic Board conversion for ARM and PowerPC, i.e.
all the boards have been converted except OpenRISC, SuperH, SPARC,
which have not supported Generic Board framework yet.
Select SYS_GENERIC_BOARD in arch/Kconfig and delete all the macro
defines in include/configs/*.h.

Now that MMC works in U-Boot add config distro command support to start
Linux in a standard fashion. One oddity here is that linux fails to load
when the fdt is relocated to above 512MB, so set fdt_high to make sure it's
loaded below that.

The Firefly RK3288 is a suitable target board for initial mainline Rockchip
support. It includes a good set of peripherals, a recent SoC and it is
readily available.
This adds only some basic files required to allow the baord to display a
serial message in SPL and hang.
