Thu Jun 5 19:33:58 CEST 2008


ARM: This patch adds support for the Lyrtech SFF-SDR
board, based on the TI DaVinci architecture (ARM926EJS).

Changes between V5 and V6:
  -New email address for contributor.
  -Init of EMIF-A CS3 address space to load FPGA.
  -Dynamic parsing of MAC address in EEPROM.
  -Add boot delay of 5 sec.
  -Use NFS for Linux boot command.
  -Add relocate flag for command history.
