Message:

sparc64 work:

• find a CPU node and read its clock_frequency attribute
• implement asm_delay_loop()
• set TICK_COMPARE register according to processor frequency
• small improvements at random places

OpenFirmware work:

• two new functions for walking the device tree

Generic boot loader work:

• added basic string functions

Usual pile of indentation and formatting fixes.
