3eb90bad65 Generic udelay() with watchdog support
According to the PPC reference implementation the udelay() function is
responsible for resetting the watchdog timer as frequently as needed.
Most other architectures do not meet that requirement, so long-running
operations might result in a watchdog reset.

This patch adds a generic udelay() function which takes care of
resetting the watchdog before calling an architecture-specific
__udelay().

095a460b49 arm nomadik: use 1000 as HZ value and rewrite timer code
This sets CONFIG_SYS_HZ to 1000 as required, and completely rewrites
timer code, which is now both correct and much smaller.  Unused
functions like udelay_masked() have been removed as no driver uses
them, even the ones that are not currently active for this board.
mtu.h is copied literally from the kernel sources.

fd14c41a86 arm nomadik: cleanup reset
There is only one public release of the Nomadik chip, so the ifdef
in reset code as well as a define in the config file are not needed

d5254f149d Initial support for Nomadik 8815 development board
The NMDK8815 board is distributed by ST Microelectornics.
Other (proprietary) code must be run to unlock the CPU before
U-Boot runs. doc/README.nmdk8815 outlines the boot sequence.

This is the initial port, with basic infrastructure and
a working serial port.
