* 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.
