        * ChangeLog: Created

        * include/board.h: IP config 3 changes

        Remove flash defines for boards which do not have it.

        Reorganise UART and Ethernet modules defines

        : Changed to point to just past top of stack.

        * reset.s: Remove flash boot options and early relocation boot code.

        Added BSS clearing code.

        * flash_reset.S: Added, containing all flash boot code.

        * config.mk: Added different optimization options (all commented out)

        * ram.ld: Add BSS symbols to help clearing.

        * include/eth.h: : Change to 8.

        : Change to 4.

        : Change to 4.

        : Added.

        * drivers/eth.c:

        (init_tx_bd_pool): Use updated version of ETH_DATA_BASE.

        (init_rx_bd_pool): Ditto.

        * include/common.h: <_src_addr>: Added as extern (symbol from linker

        script)

        * cmds/load.h: Added eth.h include.

        : Defined in one place now, set as end of SDRAM

        minus the size of the relocate and boot program.

        A few flash functions surrounded with #ifdef FLASH_BASE_ADDR so they

        are compiled in only when the flash stuff is in use.

        (init_load): Whole CFG_IN_FLASH section removed. Tboot default location

        now set as end of ethernet buffer space.

        * cmds/memory.c:

        (testram): Warnings added if memory test will clobber stack. Start

        location automatically changed to end of stack, and test will abort

        if start location is before end location.
