* Patch by Sangmoon Kim, 23 Sep 2003:
fix pll_pci_to_mem_multiplier table for MPC8245
* Patch by Anders Larsen, 22 Sep 2003:
enable timed autoboot on PXA
* Patch by David Müller, 22 Sep 2003:
- add $(CFLAGS) to "-print-libgcc-filename" so compiler driver
returns correct libgcc file path
- "latency" reduction of busy-loop waiting to improve "U-Boot" boot
time on s3c24x0 systems
* Patch by Jon Diekema, 19 Sep 2003:
- Add CFG_FAULT_ECHO_LINK_DOWN option to echo the inverted Ethernet
link state to the fault LED.
- In NetLoop, make the Fault LED reflect the link status. The link
status gets updated on entry, and on timeouts.
