Using changes in this patch we were able to reduce approx 10k size of u-boot-spl.bin image. Following is breif description of changes to reduce SPL size: 1. Changes in board/freescale/ls1043ardb/Makefile to remove compilation of eth.c and cpld.c in case of SPL build. 2. Changes in board/freescale/ls1043ardb/ls1043ardb.c to keep only ddr_init and board_early_init_f funcations in case of SPL build. 3. Changes in ls1043a_common.h & ls1043ardb.h to remove driver specific macros due to which static data was being compiled in case of SPL build. 4. Disable MMC driver from bieng compiled in case of SPL NAND build and NAND driver from bieng compiled in case of SPL MMC build. 5. Remove I2C driver support from SPL in case of LS1043ARDB.
