* 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 Mller, 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.

- CFG_FAULT_ECHO_LINK_DOWN:
Echo the inverted Ethernet link state to the fault LED.
Note: If this option is active, then CFG_FAULT_MII_ADDR
also needs to be defined.
- CFG_FAULT_MII_ADDR:
MII address of the PHY to check for the Ethernet link state.
