Hi,
first of all, read the README in the upper directory of u-boot.

The idea is to create your project's subdirectory in the "board" directory and integrate in to the build process.

Second, it seems there is already some code available for the S29GL064M in u-boot.

> rgrep S29GL064M u-boot-1.1.2/
u-boot-1.1.2/board/cmc_pu2/flash.c: case FLASH_S29GL064M:
u-boot-1.1.2/board/cmc_pu2/flash.c: printf ("S29GL064M-R6 (64Mbit,uniform sector size)\n");
u-boot-1.1.2/board/cmc_pu2/flash.c: debug ("Chip: S29GL064M-R6\n");
u-boot-1.1.2/board/cmc_pu2/flash.c: info->flash_id+= FLASH_S29GL064M;

Hope it helps
