To build a u-boot for danube board, user need to do the following things:
To configure u-boot for a proper board, user need to modify two files accordingly.

To configure u-boot for evaluation board, in danube-uboot/include/configs/danube.h, set
#define USE_EVALUATION_BOARD
#undef  USE_REFERENCE_BOARD
and vice-versa.

To let u-boot boot from ebu(flash,e.g), in danube-uboot/include/configus/danube.h, set 
#define   DANUBE_BOOT_FROM_EBU
Otherwise u-boot will be compiled for booting from RAM.

To use DDR RAM running at 111M, in danube-uboot/include/configus/danube.
h, set
#define  DANUBE_DDR_RAM_111M
#undef   DANUBE_DDR_RAM_166M
and vice-versa.

To define RAM size of RAM, in danube-uboot/include/configus/danube.
h, set
#define RAM_SIZE                0x2000000 /*32M ram*/
This is an example for a 32M RAM.


Besides above settings, user need to change danube-uboot/board/danube/config.mk to set the loading address of u-boot.
If U-Boot is to boot from EBU(flash), user needs to set
TEXT_BASE=0xB0000000
If u-boot is to boot from RAM, user needs to set
TEXT_BASE=0xa0400000

Use the script gct to build a uart downloadable u-boot image:
./gct danube_ref_ddr166.conf u-boot.srec u-boot.asc
