- Update the local bus ranges in the FDT for Linux for the various devices connected to the local bus via chip-select.

- Set the LCRR_DBYP bit in the LCRR for local bus frequencies lower than 66 MHz and uses I/O accessor functions consequently.

- UPM data update.

- Update of default environment and configuration. Use I2C multibus as we do have two I2C buses. Also enable sdram and ext2 commands.
