2011-01-07  Julius Baxter  <julius@opencores.org>
        * 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
        <ETH_DATA_BASE>: 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: <ETH_TOTAL_BD>: Change to 8.
        <ETH_TXBD_NUM>: Change to 4.
        <ETH_RXBD_NUM>: Change to 4.
        <ETH_BUF_SPACE>: 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.
        <COPYBOOT_LOCATION>: 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.
