Subject: * Patch by Sangmoon Kim, 23 Sep 2003:   fix pll_pci_to_mem_multiplier
 table for MPC8245
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* 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.
